This note relates the discovery of on species of land snails of the Vendée kind in "marais des Bourbes" (Olonne-sur-Mer) on the Vendée coast. This is the second time Vertigo moulinsiana, a rare species in Vendée, has been found.
Anax parthenope is a very rare dragonfly in Vendée. This article relates how this species bred once only in 2001 on a sand dune in Noirmoutier island.
This note states the number of grounded sperm whales on the French Atlantic coast and more especially on the coast of Vendée between 1900 and 2002.
Clé de détermination des Coléoptères Lucanides et Scarabéides de Vendée et de l’Ouest de la France
(2002)
It is an identification key of species of beetles called Lucanoideas and Scarabaeoideas already observed in Vendée and in Western France or likely to be found there some day or other. 160 species have been described, often illustrated with maps of their habitats in France.
Following the 1989-90 winter storms, remains of several straight-tusked elephants as well as a rich quaternary paleoflora were found on the strand of La Parée beach in Brétignolles-sur-Mer (Vendée, France). The story of these findings, the diggings of the bones, the dating and the paleoenvironment of the deposits are mentioned in this article. The sediments are old "peat bogs" which belong to two distinct eras : Pleistocene (peat bog holding the remains of straight-tusked elephants) and Holocene (peat bog showing tracks of Bovidae and prints of tools, and higher peat bogs).
Recent extension works of the quarry of La Gouraudière in Mauzé-Thouarsais (in Deux-Sèvres), and excavation works for the water reservoirs to irrigate the cereal fields in Le Bernard (in Vendée) led to the collection of an interesting fauna of ammonites among which several species are close to the téthysian ones.
The Revue des Sciences naturelles de l’Ouest was edited in the years 1891-97. Although poorly known, it contains valuable papers on the natural sciences in Western France, particularly in Vendée. After a short presentation, we give here the content tables of this periodical together with a list of public libraries where it can be found.
Tracks and faeces of otter are abundant around the lac du Jaunay (Vendée) but this animal is very fierce and nocturnal. Nevertheless, an otter was observed in very good condition at midday, in June. It was fishing in a small pound near the lake. This note describes the behaviour of this otter.
After 1985, the otter (Lutra lutra) was not found any more on the Sèvre Nantaise (France). From 1997, a careful exploration revealed presence signs of its presence showing the coming back of this mammal.
Observation d’une genette, Genetta genetta (Linné, 1758), sur les rives du lac du Jaunay en Vendée
(2001)
The diurnal observation of a Genet, such as the one made in the bocage of Vendée (France) related here, is exceptional because this small carnivore is said to be so shy and so exclusively nocturnal.
The Genet is a little carnivore whose status is not very well-known in Vendée (France). The methods for a county survey about these carnivores are set out in order to get information about its presence. The results will make it possible to map out an atlas showing where it is located and where it lives.
The Orchis simia is a rare orchid in Vendée (France). Historical data and the amount of books published about it are mentioned here. A new find on the limestone formation of Chantonnay has been added to the present distribution of species.
The writer mentions the existence of the Ophrys passionis in Loire-Atlantique and in Vendée (France), which are two countries where this Orchid had never be seen before. All the observations so far emphasize the hypothesis that this Orchid is different from the other related Orchids through its ability to adapt to a specific pollinator, Andrena carbonaria.
L’Ophrys petite araignée, Ophrys araneola Reichenbach 1831, redécouverte de l’espèce en Vendée
(2001)
The Ophrys araneola which had not been seen in Vendée (France) since 1993 was rediscovered in may 1993 among a colony of Ophrys sphegodes. The writer underlines the risks of eventually confusing the two species and mentions the different characteristics of each in order to avoid any confusion.
This article summarizes the observations of Odonatas gathered over the last fifteen years in Vendée. It results from collective research work by more than forty naturalists. A map locating each of the 58 species of Odonatas is given as well.
A first inventory of Yeu island’s Orthoptera (Vendée, France) allow us to list 23 species and 4 species of the allied orders Mantodea, Phasmodea and Dermaptera. A faunistic study was established on each species and a discussion gives an evaluation of the imprint of human activity on insular Orthoptera’s communities.
Background: The treatment of high-risk neuroblastoma patients consists of multimodal induction therapy to achieve remission followed by consolidation therapy to prevent relapses. However, the type of consolidation therapy is still discussed controversial. We applied metronomic chemotherapy in the prospective NB90 trial and monoclonal anti-GD2-antibody (MAB) ch14.18 in the NB97 trial. Here, we present the long term outcome data of the patient cohort. Methods: A total of 334 stage 4 neuroblastoma patients one year or older were included. All patients successfully completed the induction therapy. In the NB90 trial, 99 patients received at least one cycle of the oral maintenance chemotherapy (NB90 MT, 12 alternating cycles of oral melphalan/etoposide and vincristine/cyclophosphamide). In the NB97 trial, 166 patients commenced the MAB ch14.18 consolidation therapy (six cycles over 12 months). Patients who received no maintenance therapy according to the NB90 protocol or by refusal in NB97 (n = 69) served as controls. Results: The median observation time was 11.11 years. The nine-year event-free survival rates were 41 ± 4%, 31 ± 5%, and 32 ± 6% for MAB ch14.18, NB90 MT, and no consolidation, respectively (p = 0.098). In contrast to earlier reports, MAB ch14.18 treatment improved the long-term outcome compared to no additional therapy (p = 0.038). The overall survival was better in the MAB ch14.18-treated group (9-y-OS 46 ± 4%) compared to NB90 MT (34 ± 5%, p = 0.026) and to no consolidation (35 ± 6%, p = 0.019). Multivariable Cox regression analysis revealed ch14.18 consolidation to improve outcome compared to no consolidation, however, no difference between NB90 MT and MAB ch14.18-treated patients was found. Conclusions: Follow-up analysis of the patient cohort indicated that immunotherapy with MAB ch14.18 may prevent late relapses. Finally, metronomic oral maintenance chemotherapy also appeared effective.
Der Stockberg bei Ottbergen, Kreis Höxter, wurde 1982 nach fast zwanzigjährigem Bemühen der Naturkundler unter Schutz gestellt. Bereits in den beiden über dieses Gebiet veröffentlichten Arbeiten von KOPPE (1962) und LEWEJOHANN (1964) wird die floristische Bedeutung des Berges hervorgehoben. BRINKMANN (1978) bezeichnet ihn gar als wertvollsten und artenreichsten Muschelkalkhang im gesamten Regierungsbezirk Detmold.
An der Abteilung Höxter der Universität -Gesamthochschule- Paderborn wurde 1977 der Fachhochschulstudiengang Landespflege eingerichtet. Im Juli 1980 wurde ich nach Höxter berufen, um das Lehrgebiet "Vegetationskunde (Pflanzensoziologie/-ökologie)" zu vertreten. Zum Aufgabenbereich gehört auch ein Teil des Lehrgebietes "Freilandpflanzenkunde, Pflanzenverwendung", und zwar der Bereich der einheimischen Wildpflanzen und der Pflanzensystematik.
Im vorigen Jahrhundert waren die durchschnittlichen Ernteerträge in der Landwirtschaft weit geringer als heute. Mißernten, die meist durch ungünstige Witterungsverhältnisse, aber auch durch Pflanzenkrankheiten und Schädlinge bedingt waren, konnten für die Bevölkerung zur Katastrophe werden. Der Witterungsverlauf in unserem Raum sowie seine und sonstige Auswirkungen auf die Ernteergebnisse und die Versorgungslage von den ersten Jahrzehnten des vorigen Jahrhunderts bis zum Jahre 1863 sind der Gegenstand dieses Beitrages.
Jedem an Natur und Landschaft interessierten Wanderer, der mit offenen Augen unsere Heimat durchstreift, fällt die große Zahl der Steinbrüche auf, auf die er in Wald und Feld stößt. Da sind sowohl die kleinen Brüche, die, heute meist aufgelassen, einst dem Bedarf eines Dorfes oder dem Waldwegebau dienten. Da sind aber auch riesige Steinbrüche, in denen auch jetzt noch mit großem technischen Aufwand Steine gebrochen werden.
A review of biological control efforts against Diptera of medical and veterinary importance includes pertinent literature of major dipterous taxonomic groups where some success has been achieved or where work is currently being conducted on species breeding in aquatic (e.g., mosquitoes, blackflies, tabanids) and terrestrial habitats (muscids, tsetse, etc.). Most effort has been directed against aquatic Diptera because of the human and animal disease agents they transmit. Research has established that the natural enemy component frequently is responsible for significant population reduction and indispensable to integrated control which seeks to maintain populations below annoyance or disease transmission levels. The manipulation of natural enemies through introduction and/or augmentation has in some cases provided satisfactory control, and sustained releases of natural enemies over several years may overcome the relative high cost of massive release rates. Ultimately, to guarantee the existence and maximum expression of resident natural enemies has become almost universally accepted, and challenging, to sound control practices. Indeed, chemical industry recognizing this, has sought to manufacture products such as Bacillus toxins, juvenile hormones, and baits that are minimally disruptive to existing natural controls. Although such easily applied products have been widely adopted, their cost continues to become prohibitive with developing resistance, as was observed earlier with many organophosphate and chlorinated hydrocarbon insecticides. Further advancements in the control ofthese Diptera should continue to embrace a sound appreciation for the natural control component and nurture ways to allow its maximum expression.

Unter den zahlreichen einheimischen Arten der Nagetiere sind die Bilche oder Schläfer am wenigsten bekannt. Das liegt an ihrer heimlichen, vorwiegend in der Dämmerung und bei Nacht aktiven Lebensweise, sowie ihrer lückenhaften Verbreitung. Von den vier europäischen Schläfern kommen bei uns im Kreis nur zwei, nämlich Siebenschläfer und Haselmaus, vor.
Anfang Mai 1982 trafen Mitglieder unseres Vereins auf ein aufsehenerregendes Vorkommen der Frauenschuh-Orchidee im Altkreis Warburg. Das war Anlaß, die Umgebung des Standorts näher zu erkunden. In vier Begehungen von Mai bis September konnte ich einen ungefähren Einblick in die Flora dieses Gebiets gewinnen. Zu erschöpfenden Aussagen wären Beobachtungen über mehrere Vegetationsperioden hinweg notwendig.
Johann Konrad Schlaun, berühmt gewordener Barockbaumeister des Fürstbischofs zu Münster, verbrachte seine ersten Lebensjahre und frühe Jugendzeit in Nörde, einem kleinen Dörfchen in der südlichen Eggelandschaft. Seinem Vater, Heinrich Schlaun, oblag in diesem Orte und seiner Nachbarschaft die Wahrnehmung wirtschaftlicher und eingeschränkt hoheitlicher Belange des Klosters Hardehausen. Das bezeugt ein Schreiben des damaligen Abtes von Hardehausen, F. Stephan Overgar, "Unserm Richter zu Nörde einzuhändigen",
Dieser aus den Wäldern Nordamerikas stammende Bär gehört zur Familie der Kleinbären. Er erreicht ein Gewicht von ca. 10 kg und eine Länge von 80 bis 90 cm. Seine Haarfarbe ist gelblichgrau, mit Schwarz durchsetzt. Bärinnen scheinen etwas heller gefärbt. Der etwa 25 cm lange Schwanz ist mehrfach schwarz quergebändert. Eine larvenartige schwarze Gesichtsmaske paßt zu dem unsteten nächtlichen Räuberleben des Waschbären. Seine Beine sind mäßig lang, fünfzehig und mit langen Krallen bewehrt. Die Fußsohlen berühren beim Gehen den Boden in voller Länge und sind unbehaart; die Sprungspur hat daher Ähnlichkeit mit der des Steinmarders.
Arthropods use fluid medium motion-sensing filiform hairs on their exoskeleton to detect aerodynamic or hydrodynamic stimuli in their surroundings that affect their behaviour. The hairs, often of different lengths and organized in groups or arrays, respond to particular fluid motion amplitudes and frequencies produced by prey, predators, or conspecifics, even in the presence of background noise peculiar to the environment. While long known to biologists and experimentally investigated by them, it is only relatively recently that comprehensive physical-mathematical models have emerged offering an alternative methodology for investigating the biomechanics of filiform hair motion. These models have been developed and applied to quantitatively predict the performance characteristics of filiform hairs in air and water as a function of the relevant parameters that affect their physical behaviour. They even allow the exploration of possible biological evolutionary paths for filiform hair changes resulting from physical selection pressures. In this chapter we review the state of knowledge of filiform hair biomechanics and discuss two physical-mathematical models to predict hair dynamical behaviour. One modelling approach is analytically exact, serving for quantitative purposes, while the other, derived from it, is approximate, serving for qualitative guidance concerning the parameter dependencies of hair motion. Using these models we look in turn at the influence of these parameters and the fluid media physical properties on hair motion, including the possibility of medium-facilitated viscous coupling between hairs. The models point to areas where data is currently lacking and future research could be focused. In addition, new results are presented pertaining to transient tlows. We qualitatively explore the possibility of an overlapping water-air niches adaptation potential that may explain how, over many generations, the filiform hairs of an arthropod living in water could have evolved to function in air. Because flow-sensing hairs have served to inspire corresponding artificial medium motion microsensors, we discuss recent advances in this area. Significant challenges remain to be overcome, especially with respect to the materials and fabrication techniques used. In spite of the impressive technological advances made, nature still remains unrivalled.
Anthropologischer Verein zu Göttingen : die Ausgrabung des neolithischen Dorfes bei Diemarden
(1911)
Anthropologischer Verein zu Göttingen. In der Sitzung am 11. Mai 1910 wurde zunächst an Sitelle des bisherigen Vorsitzenden Prof. Max Verworn, der sich vom Verein verabschiedete, um einem Ruf an die Universität Bonn zu folgen, Herr Prof. Dr. Fr. Merkel zum Vorsitzenden gewählt und die frei gewordene Stelle im Vorstande durch die Wahl des Herrn Prof. Dr. Heiderich wieder besetzt. Sodann erstattete Herr Prof. Max Verworn einen ausführlichen Bericht über "Die Ausgrabung des neolithischen Dorfes bei Diemarden"
The birds of Billiton Island
(1937)
Resume 1) The egg of Squilla oratoria DE HAAN is centrolecithal and undergoes partial cleavages resulting in rudimentary primary yolk pyramids. 2) The germinal disk is first represented by a pair of optic lobes and a ventral plate, which are afterward connected by paired, lateral ectoderm thickenings to form a V-shape. The V is then transformed into an O by the appearance of a transverse band between the optic lobes of both sides. 3) A small blastopore is formed. Of the mesendoderm cells derived from the blastopore by cell immigrations, those attached to the lower surface of the lateral ectoderm thickenings are differentiated into a U-shaped, naupliar mesoderm band. This inesoderm band joins the preante:mulary mesoderm derived from the optic lobe, and grows into a complete ring conforming to the shape of the germinal disk. 4) The extra-blastoporic immigrants consist of a preantennulary mesoderm, mesodermal yolk cells and a part of the naupliar mesoderm. The greater part of the preantennulary mesoderm cells disintegrate sooner or later, without forming any distinct structure. The mesodermal yolk cells also degenerate after taking part in the dissolution of the deutoplasm. A discussion as regards the mutual relationship between these elements, with the conclusion that the formation of the preantennulary mesoderm represents the initial step of the extra-blastoporic cell sinking from the whole egg surface, is included. 5) The endodermal elements consist of a compact cell mass differentiated from the posterior part of the mesendoderm layer and the endodermal yolk cells immigrated from the blastopore. The yolk cells, after migrating through the most peripheral part of the yolk, scatter all over its surface. The endoderm plate is nothing but a mass of yolk cells. which remain without scattering. 6) Eight mesoteloblasts derived from the blastoporic lip are attached to the inner surface of the thoracico-abdominal process, making four groups. The ectoteloblasts are differentiated from the ordinary blastoderm cells in a later stage than the mesoteloblasts. In the final condition they consist of 21 cells forming a complete ring around the thoracico-abdominal process. 7) Both the ectoderm and the mesoderm are derived from the teloblasts in all of the post-naupliar segments.· The dorsal ectoderm, however, is non-teloblastic in only a few anterior segments. Differentiation of segments proceeds from the front toward the back. 8) The telson mesoderm is formed by the cells sunk from the telson ectoderm which is derived from the peri-blastoporic ectoderm . 9) The anus is the remnant of the blastopore. In accordance with the change of the caudal furca, the anus is displaced from the dorsal side of the telson to the ventral border between this and the last abdominal segment. 10) There is a distinct nauplius stage. Of the meta-naupliar segments, those from the m:txillula to the second maxilliped are laid on the germinal disk, the following segments together forming a thoracico-abdominal process. Two maxiliiped segments, however, are later separated from the cephalon with the development of the carapace fold, and join the trunk segments. Externally, six abdominal segments are formed. 11) The ganglionic cells are proliferated from the neuroblasts occupying the most superficial part of the centra1 nervous system. The giant ganglionic cells arise from the ordinary ganglionic cells and not directly from neuroblasts. The development of the cerebrum is described. The tritocerebra of both sides are conne~ted by a transverse nerve-fibre bundle behind the stomodaeum. The ganglia of the segments from the mandible to the second maxilliped first exhibit a typical ladder-like shape. Of these ganglia, the anterior three constitute a sub-resophageal ganglion by more or less complete fusion, while the posterior two are transferred from the cephalon to the thoracico-abdomimil process with the constriction of the segments. The inter-ganglionic cell groups take part in the constriction of the consecutive segments. The seventh abdominal ganglion is clearly indicated by the presence of such a cell group as well as of a pair of nerve fibre masses. 12) The development of the compound eye is traced. The ganglion opticum is derived from the ectoderm of the optic lobe lateral to the protocerebrum; it is not an outgrowth of the cerebrum. 13) The ganglion visceralum is differentiated from the anterior wall of the stomodaeum. 14) A median dorsal organ is formed. In close connection with the activity of this organ, the embryo undergoes one ecdysis. 15) The mid-gut epithelium is formed by the gradual expansion of the anterior and posterior endoderm plates over the yolk sac. These plates, however, extend only on the ventral side of the yolk sac before hatching. The posterior plate is produced by the concentration of the scattered yolk cells toward the periphery of the. plate differentiated from the mesendoderm, while the anterior plate is formed by yolk cells alone. 16) The greater part of the intestine develops from the outgrowth of the posterior endoderm epithelium, the proctodaeum occupying only the rectum. 17) The posterior liver lobes are produced from the posterior endoderm plate as a pair of blind tubes and extend as far backward as the telson. The anterior liver lobes and the lateral mid-gut cceca are rather incompletely developed, being ~eparated by shallow superficial grooves of the yolk sac. These two pairs of diverticula are only partially covered by the endoderm epithelium, and develop into more or less distinct coeca during larval life. They later seem to be completely absorbed again by the mid-gut. 18) The product of each division of the mesoteloblast is equivalent to one mesodermal-segment. The mesoderm of the seventh abdominal segment is derived from the posteriorly situated daughter cell produced by the last division of the teloblast. In' accordance with the grouping of teloblasts, the trunk mesoderm is separated into two ventral and two dorsal bands. Each band is further separated into segmentally arranged blocks, the somites. The ccelom develops in no stage and in no segment. 19) The dorsal mesoderm gives rise to the extensor and the oblique muscles of the trunk, the anterior and posterior limb muscles, as well as to the mesodermal inclusion of the limb. The -ventral mesoderm grows into the flexor. The connective tissue investing the intestine -and the liver lobes are principally constructed from the dorsal mesoderm. The germ cell does not appear until hatching. A brief account is also given of the fate of the naupliar mesoderm. 20) The heart wall and the pericardial floor are morphologically one unit. They arise from the dorsal mesoderm as a pair of membranes stretching between it and the intestine. The dilated and elongated parts of the heart are formed by the subsequent union of these paired rudiments. 21) The anterior dorsal vessel has a two-fold origin; it is formed by the fusion of an anterior rudiment extending backward from the rostrum and a posterior one developing as a tubular outgrowth of the heart. The former is derived from the rearrangement of mesenchymatous cells which migrated from the anterior end of the naupliar mesoderm. 22) By the time of hatching, two pairs of lateral vessels are formed as hollow linear thickenings of the pericardial floor in front and behind the dilated part of the heart. 23) The antennal gland remains rudimentary without acquiring any intercellular lumen. The maxillar gland is not laid until hatching. The labral and anal glands are derived from the peristomodaeal and the telson mesoderm respectively. 23) Comparisons are made bewteen Squilla and other orders of Malacostraca as regards the salient points of the embryonic development. These have led to the conclusion that the Stomatopoda are most closely related in their embryonic development to Nebaliacea, and further that Stomatopoda represent a rather primitive group separated from the main stem of Malacostraca very early, only next in order to Nebaliacea.
