Effects of habitat loss and fragmentation on the abundance and species richness of aphidophagous beetles and aphids in experimental alfalfa landscapes
(Czech Academy of Sciences, 2008)
In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, such as foliarforaging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild ...
Assessing how habitat loss restricts the geographic range of Neotropical anurans
Habitat loss and fragmentation exert unquestionable negative effects in a wide range of taxa on both regional and local scales. However, there is a debate over whether habitat change impacts geographic species distribution. ...
Short-term effects of habitat fragmentation on the abundance and species richness of beetles in experimental alfalfa micro-landscapes
(Sociedad de Biología de Chile, 2004)
The use of native vegetation as a proxy for habitat may overestimate habitat availability in fragmented landscapes
Native vegetation is often used as a proxy for habitat to estimate habitat availability in landscapes. This approach may lead to incorrect estimates of the impacts of habitat loss and fragmentation on species, which have ...
Persistence of plants and pollinators in the face of habitat loss: Insights from trait-based metacommunity models
(Elsevier Academic Press Inc, 2015-11)
The loss of natural habitats is one of the main causes of the global decline of biodiversity. Understanding how increasing habitat loss affects ecological processes is critical for mitigating the effects of environmental ...
Effects of habitat loss, habitat fragmentation, and isolation on the density, species richness, and distribution of ladybeetles in manipulated alfalfa landscapes
1. Habitat loss and fragmentation are the main causes of changes in the distribution and abundance of organisms, and are usually considered to negatively affect the abundance and species richness of organisms in a landscape. ...
Bird responses to forest loss: the influence of habitat specialization
(Wiley Blackwell Publishing, Inc, 2017-02)
Aim: Due to intrinsic differences in the sensitivity to habitat grain among species, studies performed at different extent are necessary to understand the consequences of forest loss and fragmentation. Using a large database, ...
Unraveling the drivers of community dissimilarity and species extinction in fragmented landscapes
(ECOLOGICAL SOC AMERWASHINGTON, 2012)
Communities in fragmented landscapes are often assumed to be structured by species extinction due to habitat loss, which has led to extensive use of the species-area relationship (SAR) in fragmentation studies. However, ...
How population loss through habitat boundaries determines the dynamics of a predator-prey system
(Elsevier B.V., 2014-12-01)
The increased persistence of predator-prey systems when interactions are distributed through the space has been acknowledged by both empirical and theoretical studies. One salient feature of predator-prey interactions in ...
