Insect populations including butterflies are declining worldwide, and they are becoming an
urgent conservation priority in many regions. Understanding which butterfly species migrate …

Studies of host specificity in tropical insect herbivores are evolving from a focus on insect
distribution data obtained by canopy fogging and other mass collecting methods, to a focus …

Most eukaryotic organisms are arthropods. Yet, their diversity in rich terrestrial ecosystems is
still unknown. Here we produce tangible estimates of the total species richness of …

Insects and other arthropods are central to terrestrial ecosystems. However, data are lacking
regarding their global population abundance. We synthesized thousands of evaluations …

The paper presents data on the use of simple crown traps for studying the insect fauna. The
crown trap is a five-litre plastic container with a window cut out on one side of it at a distance …

The Cape Floristic Region of South Africa is a global biodiversity hotspot. In 1998, a process
of conservation planning began in the region that required quantitative targets for …

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a
major role in regulating the global climate. They support the livelihoods of a substantial …

Sex roles are typically thought of as being fixed for a given species. In most animals males
compete for females, whereas the females are more reluctant to mate. Therefore sexual …

▪ Abstract The diversity and composition of herbivore assemblages was a favored theme for
community ecology in the 1970s and culminated in 1984 with Insects on Plants by Strong …

Forest canopies represent the functional interface between 90% of the Earth's terrestrial
biomass and the atmosphere and include some of the most threatened of all terrestrial …
