Species traits may predict extinction risk of Azorean endemic arthropods
Ground‐dwelling endemic arthropods face a higher extinction risk due to habitat degradation and invasive plants. Canopy species may seem less threatened but still face extinction risks from habitat fragmentation. Body size and trophic group did not predict species threat levels.

Two new species of Sinacroneuria Yang & Yang, 1995 (Plecoptera: Perlidae) from China
Two new species of the stonefly genus Sinacroneuria, S. aequalis sp. nov. and S. transversa sp. nov., are described and illustrated from the Fujian and Zhejiang provinces of China. These new taxa are compared with related congeners.

The vulnerability of British aquatic insects to climate change
Freshwater ecosystems are particularly at risk from climate change due to the intrinsic link between the physical properties of the water environment and those species that live there. Mayflies, stoneflies and caddisflies are key indicators of the health

Active predators do not necessarily specialize in sedentary prey: A simulation model
Active predators, which move to find food, are assumed to specialize in sedentary prey. This study used an individual‐based simulation to test whether this assumption holds. The results show that active predators do not always specialize in sedentary prey; instead, prey choice greatly depends on prey spatial pattern and competition with ambush ...

Aquatic habitat response to small dam removal demonstrates recovery in three years
Abstract Dams disrupt river networks by interrupting longitudinal transport of sediment and nutrients and obstructing the movement of aquatic organisms. Increasingly, water resource managers are looking for dam removal as a solution to restore connectivity and improve aquatic habitats, water quality, and fish passage.

What Are the Phylogenetic Limits to Pollinator Diversity?
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

Endemic Flora and Fauna of Arkansas [PDF]
Arkansas has an amazing diversity of plants and animals contained within its political boundaries. Forty-seven taxa are reported as Arkansas endemics, including seven plants, thirteen crustaceans (two amphipods, three isopods, eight crayfishes), nine ...

Abstract The tidal freshwater zone is an aquatic transition zone that links a river to its estuary and provides an important habitat used in the life cycle of resident and migratory fishes. Yet, information on the trophic structure of fishes in this habitat is scarce. To address this gap, we characterize the trophic structure of a fish community in the
