Extreme weather impacts on butterfly populations in Southern Texas, USA
Journal of Insect Conservation - - Trang 1-14 - 2023
Climate change is altering biodiversity of ecosystems worldwide by causing shifts in species’ home ranges, potential extinctions of species, and Extreme Climatic Events (ECEs), such as hurricanes and extreme temperatures. The purpose of this study was to examine effects of two extreme weather events on butterfly populations in the Gulf Prairies and Marshes ecoregion in Willacy and Kenedy Counties,...... hiện toàn bộ
Farmland biodiversity: wildflower-sown islands within arable fields and grassy field margins both promote spider diversity
Journal of Insect Conservation - Tập 26 - Trang 415-424 - 2021
Agricultural intensification and the concomitant landscape homogenization is leading to a worldwide decline in farmland biodiversity. Non-crop habitats in agroecosystems may counteract the loss of arthropods such as spiders and thus contribute to sustainable agriculture. However, the effectiveness of field margins and set-aside wildflower-sown patches in maintaining spider diversity is not well un...... hiện toàn bộ
Distribution, Ecology and Population Dynamics of the American Burying Beetle [Nicrophorus Americanus Olivier (Coleoptera, Silphidae)] in South-central Nebraska, USA
Journal of Insect Conservation - Tập 3 - Trang 171-181 - 1999
The endangered American burying beetle, Nicrophorus americanus Olivier, was previously widespread throughout eastern North America. In the past century numbers of this beetle have drastically declined and currently remnant populations are known from only six states despite intensive surveying efforts conducted for the last nine years. Efforts aimed at discovering and managing remnant populations h...... hiện toàn bộ
Patch shape alters spider community structure: links between microhabitat choice and sensitivity to increased edge habitat
Journal of Insect Conservation - Tập 16 - Trang 581-589 - 2011
Increased edge effects in fragmented habitats can affect the abundance of edge-dwelling organisms, but these impacts may depend on the biological attributes of species. Microhabitat choice, a species characteristic that reflects combinations of biological traits, may affect the ability of peripheral species to take advantage of increased edge habitat in the presence of edge effects. In this field ...... hiện toàn bộ
Pitfall trapping of scarce Orthoptera at a coastal nature reserve in Essex, UK
Journal of Insect Conservation - Tập 10 - Trang 371-373 - 2006
The value of pitfall trapping was questioned in a recent review of methods for sampling Orthoptera in grassland ecosystems. However, subsequent to the publication of this review, interesting data has become available from pitfall trapping at Colne Point, an important coastal nature reserve in Essex, UK. As a result of this trapping, the nationally scarce and Essex Red Data List species, Platycleis...... hiện toàn bộ
Effect of forest removal on the abundance of the endangered American burying beetle, Nicrophorus americanus (Coleoptera: Silphidae)
Journal of Insect Conservation - Tập 13 - Trang 37-43 - 2007
We test the hypothesis that the decline of the endangered American burying beetle (Nicrophorus americanus) from over 90% of its original range is the result of habitat loss and fragmentation of eastern North America. Forest removal at a site in southeastern Oklahoma known to have a significant population of N. americanus gave us a unique opportunity to test this hypothesis. At the local scale of t...... hiện toàn bộ
Host plant pattern and variation in climate predict the location of natal grounds for migratory monarch butterflies in western North America
Journal of Insect Conservation - Tập 14 - Trang 731-744 - 2010
The breeding grounds of migrant generation monarch butterflies in eastern North America are well known. In stark contrast the location of natal grounds of western migrants has not been delineated. We show that 55% of the area within seven western states was potential breeding range based on: (1) the occurrence of milkweed host plant species with phenology making them available during late-summer a...... hiện toàn bộ
Impacts of the invasive hornet Vespa velutina on native wasp species: a first effort to understand population-level effects in an invaded area of Europe
Journal of Insect Conservation - Tập 26 - Trang 663-671 - 2022
Invasive alien species could generate a multitude of impacts towards native species. The introduction and spread of Vespa velutina in Europe is raising concern for the conservation of insect’s biodiversity, including wasps due to predation, competition or a combination of these two mechanisms. Nevertheless, most evidence for negative effects on other wasps are based on laboratory experiments, dire...... hiện toàn bộ
Entomological and functional role of floral strips in an organic apple orchard: Hymenopteran parasitoids as a case study
Journal of Insect Conservation - Tập 16 - Trang 315-318 - 2012
Habitat manipulation techniques improve the availability of resources required by natural enemies to increase their effectiveness. This study focused on the effects of floral strips on Hymenopteran parasitoid presence. The experiments were conducted during spring 2007 in one organic low-input apple orchard located in south-eastern France. The density and the diversity of parasitic wasps collected ...... hiện toàn bộ
