Mammal ecology in fragmented landscapes: beyond the effects of habitat amount
(Universidade Estadual Paulista (Unesp), 2020-09-03)
A conversão de áreas naturais para uso antropogênico da terra causa perda, fragmentação e degradação de habitat, as quais são as principais ameaças para a conservação de mamíferos terrestres em todo o mundo. Nesta tese ...
Effects of habitat loss, habitat fragmentation, and isolation on the density, species richness, and distribution of ladybeetles in manipulated alfalfa landscapes
(WILEY, 2006)
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. ...
Mechanisms affecting population density in fragmented habitat
(RESILIENCE ALLIANCE, 2005-06)
We conducted a factorial simulation experiment to analyze the relative importance of movement pattern, boundary-crossing probability, and mortality in habitat and matrix on population density, and its dependency on habitat ...
Edge effects and their influence on habitat suitability calculations: a continuous approach applied to birds of the Atlantic forest
(British Ecological Society, 2012-01-18)
1. The suitability of human-modified habitats for native species and the response of species to habitat edges are two important ecological processes that affect species and communities in fragmented landscapes. However, ...
Indirect effects of habitat loss via habitat fragmentation: A cross-taxa analysis of forest-dependent species
(Elsevier B.V., 2020-01-01)
Recent studies suggest that habitat amount is the main determinant of species richness, whereas habitat fragmentation has weak and mostly positive effects. Here, we challenge these ideas using a multi-taxa database including ...
Short-term effects of habitat fragmentation on the abundance and species richness of beetles in experimental alfalfa microlandscapes
(SOCIEDAD BIOLOGIA CHILE, 2004-09)
Habitat loss and fragmentation are considered as the main causes of biodiversity depression. Habitat loss implies a reduction of suitable habitat for organisms, and habitat fragmentation is a change in the spatial configuration ...
Effects of habitat degradation on the abundance, richness and diversity of raptors across Neotropical biomes
(Elsevier, 2009-10)
Population growth and human development result in biodiversity loss and biological homogenization not only in developed countries, but increasingly in the less developed countries as well. In those countries, where ...
Habitat amount, habitat heterogeneity, and their effects on arthropod species diversity
(Brasil, 2013)
Not all studies have empirically supported the model that predicts a positive relationship between habitat heterogeneity and biodiversity. We hypothesized that these different results stem from the methods used to assess ...
