Coastal heathland succession influences butterfly community composition and threatens endangered butterfly speciesJournal of Insect Conservation - Tập 18 - Trang 111-120 - 2014
Jens Schirmel, Thomas Fartmann
Succession has a strong influence on species diversity and composition of semi-natural open terrestrial ecosystems. While several studies examined the effects of succession on butterflies in grassland and forest ecosystems, the response of heathland butterflies to succession had not been investigated so far. To address this issue we sampled butterfly abundance and environmental parameters on the B...... hiện toàn bộ
Status of the regal fritillary (Speyeria idalia) and effects of fire management on its abundance in northeastern Kansas, USAJournal of Insect Conservation - Tập 11 - Trang 299-308 - 2006
Alexis F. L. A. Powell, William H. Busby, Kelly Kindscher
The Regal Fritillary (Speyeria idalia), which once occupied prairies and meadows in North America from the upper Great Plains to the Atlantic coast, has disappeared in recent decades from nearly the entirety of the eastern half of its range and has declined westward. In the Great Plains, where the species is limited to native prairie remnants, several large populations are thought to exist, but pa...... hiện toàn bộ
Utilising museum data for comparative analysis of threatened insect speciesJournal of Insect Conservation - Tập 24 - Trang 793-804 - 2020
Simon Connolly, Darren Ward
Insect conservation is often impeded by a lack of species-specific data leading to difficulties in assessment of conservation and threat status. Utilising specimens and records held within natural history museums may help to overcome such limitations. We used specimens and their associated data from the New Zealand Arthropod Collection to provide a comparative analysis of threatened species and th...... hiện toàn bộ
Elephant impact on dragonfliesJournal of Insect Conservation - Tập 12 - Trang 493-498 - 2007
Michael J. Samways, Paul B. C. Grant
African elephants and other indigenous megaherbivores have a major impact on local vegetation structure, including aquatic communities, as their big feet and large mass pound the fringes of water bodies. This disturbance is likely to have a profound influence on the structure and composition of insect assemblages in these habitats. We investigated which dragonfly (Odonata) species were tolerant of...... hiện toàn bộ
Wastelands: their attractiveness and importance for preserving the diversity of wild bees in urban areasJournal of Insect Conservation - Tập 23 - Trang 573-588 - 2019
Lucyna Twerd, Weronika Banaszak-Cibicka
Urban wastelands are important substitute habitats for many insect species, but their value for the protection of wild bees is still poorly studied. We assessed species richness, abundance, and the diversity of wild bees in wastelands that differed in area (2–35 ha), stage of ecological succession, location (suburbs or closer to the city centre), and history of land use. In the investigated plots,...... hiện toàn bộ
Possible Metapopulation Structure of the Threatened ButterflyPyrgus armoricanus in SwedenJournal of Insect Conservation - Tập 10 - Trang 43-51 - 2006
Erik Öckinger
Many insect species dependent on patchily distributed habitats have been shown to exist as metapopulations. Here I investigated the occurrence patterns of the butterfly Pyrgus armoricanus at its northern range margin in Sweden. This was done by mapping all potentially suitable habitat patches within the only area in Sweden where the species occurs (ca. 10├ù20┬ákm), and thereafter checking for pres...... hiện toàn bộ
