A database of larval host plants for the tortricid tribe Grapholitini (Lepidoptera: Tortricidae: Olethreutinae) is presented, and larval hosts are summarized for each genus. Food plants have been reported for over 400 of the approximately 1,644 described species of Grapholitini. Of the 81 genera currently assigned to the tribe, at least one larval host has been reported for 51. Ninety-seven different plant families have been reported at least once for a species of Grapholitini, with the greatest number of grapholitines recorded from Fabaceae (168 species), followed by Fagaceae (43 species), Pinaceae (43), Sapindaceae (36), Rosaceae (30), Asteraceae (30), Euphorbiaceae (15), Rutaceae (12), Annonaceae (12), Salicaceae (11), and Cupressaceae (11). Thirty-two genera appear to be restricted, or nearly so, to specific host families, but many of these are either monotypic or are represented by exceedingly few records. Extraordinarily, entomophagy is well documented in three genera: Andrioplecta, Coccothera, and Parapammene. Two new combinations are provisionally proposed based on hosts and male genitalia: Andrioplecta magnetica (Meyrick, 1928), new combination, and A. theristis (Meyrick, 1912), new combination, both of which are currently assigned to “Grapholitini unplaced species.”

This work is the first attempt to integrate into one list and quantify all the known species of Guade loupean insects. It includes all the species known to us to be reported for the island of Guadeloupe until the 31st of December 2019. A total of 3097 valid species are listed, of which the largest component is the beetles (1447 species). Preliminarily, 632 species (20%) are considered to be strictly endemic to Guadeloupe, and 250 species are recognized as adventive or introduced. The bibliography complements the taxonomic information and includes over 350 titles. Brief annotations are also given on the history of entomology in Guadeloupe. This list includes four new island records for Guadeloupe: Azeta rhodogaster Guenée, 1852 (Lepidoptera: Erebidae), Eudocima apta (Walker, 1857) (Lepidoptera: Erebidae), Urania leilus (Linnaeus, 1758) (Lepidoptera: Uraniidae) and Micronotus quadriundulatus (Redtenbacher, 1892) (Orthoptera: Tetrigidae), all recently collected in Guadeloupe.
Heat stress transcription factors (HSFs) regulate transcriptional response to a large number of environmental influences, such as temperature fluctuations and chemical compound applications. Plant HSFs represent a large and diverse gene family. The HSF members vary substantially both in gene expression patterns and molecular functions. HEATSTER is a web resource for mining, annotating, and analyzing members of the different classes of HSFs in plants. A web-interface allows the identification and class assignment of HSFs, intuitive searches in the database and visualization of conserved motifs, and domains to classify novel HSFs.
We aimed to assess the utility of the Global Compendium of Weeds (GCW) as an indicator of plant invasiveness, by relating it to invasiveness at smaller scales. We correlated two global measures of invasiveness for alien plant species taken from the GCW (the total number of references for each species and the number of continental areas they are reported from), against distribution data from 18 regions (countries and continents). To investigate relationships between correlation strength and region size and spatial resolution (size of distribution units), we conducted meta-analyses. Finally, invasiveness measures were correlated against the number of habitats occupied by alien plant species and their median abundance in those habitats, in fine-scale vegetation plots in the Czech Republic and the state of Montana (USA). The majority of Spearman’s rho coefficients between GCW-derived invasiveness and regional distributions were less than 0.4. Correlation strength was positively related to region size and resolution. Correlations were weaker when the number of habitats occupied by a species, and species abundances within occupied habitats, were considered. We suggest that the use of the GCW as an invasiveness measure is most appropriate for hypotheses posed at coarse, large scales. An exhaustive synthesis of existing regional distributions should provide a more accurate index of the global invasiveness of species.
Der Global Index of Vegetation-Plot Databases (GIVD) ist eine Metadatenbank von Vegetations - datenbanken weltweit, die im Jahr 2010 von einem internationalen Leitungsgremium ins Leben gerufen wurde und auf einem Server in Greifswald beheimatet ist. Ziel von GIVD ist es, einen besseren Überblick über die zunehmende Zahl von Vegetationsdatenbanken zu geben und ihren Inhalt für übergreifende vegetationsökologische Analysen zu erschließen. Im vorliegenden Beitrag analysieren wir, welche Daten aus Mitteleuropa (incl. Benelux-Länder) in GIVD derzeit registriert sind. Am 20. März 2011 stammten 1,35 Millionen der insgesamt registrierten 2,45 Millionen Vegetationsaufnahmen aus den 12 betrachteten Ländern. Mit über 600.000 digital verfügbaren Vegetationsaufnahmen entsprechend einer Dichte von 18 km–2 sind die Niederlande weltweit führend.
