Environmental indicators of macroinvertebrate and fish assemblage integrity in urbanizing watersheds
Urbanization compromises the biotic integrity and health of streams, and indicators of integrity loss are needed to improve assessment programs and identify mechanisms of urban effects. We investigated linkages between landscapes and assemblages in 31 wadeable Piedmont streams in the Etowah River basin in northern Georgia (USA). Our objectives were to identify the indicators of macroinvertebrat...
متن کاملFish assemblage responses to forest cover.
We investigated whether fish assemblage structure in southern Appalachian streams differed with historical and contemporary forest cover. We compared fish assemblages in 2(nd)-4(th) order streams draining watersheds that had increased forest cover between 1950 and 1993 (i.e., reforesting watersheds). We sampled fish in 50 m reaches during August 2001 and calculated catch-per-unit-effort (CPUE) ...
متن کاملThresholds of species loss in Amazonian deforestation frontier landscapes.
In the Brazilian Amazon, private land accounts for the majority of remaining native vegetation. Understanding how land-use change affects the composition and distribution of biodiversity in farmlands is critical for improving conservation strategies in the face of rapid agricultural expansion. Working across an area exceeding 3 million ha in the southwestern state of Rondônia, we assessed how t...
متن کاملAssessing the Relationship Between Vegetation Structure and Harvestmen Assemblage in an Amazonian Upland Forest
14 1. Arthropod diversity and non-flying arthropod food web are strongly influenced by 15 habitat components related to plant architecture and habitat structural complexity. 16 However, we still poorly understand the relationship between arthropod diversity and the 17 vegetation structure at different spatial scales. Here, we examined how harvestmen 18 assemblages are distributed across six loc...
متن کاملGround-Vegetation Clutter Affects Phyllostomid Bat Assemblage Structure in Lowland Amazonian Forest
Vegetation clutter is a limiting factor for bats that forage near ground level, and may determine the distribution of species and guilds. However, many studies that evaluated the effects of vegetation clutter on bats have used qualitative descriptions rather than direct measurements of vegetation density. Moreover, few studies have evaluated the effect of vegetation clutter on a regional scale....
