Habitat quality, not habitat amount, drives mammalian habitat use in the Brazilian Pantanal
(2021-01-01)
Context: An understanding of species-habitat relationships is required to assess the impacts of habitat fragmentation and degradation. To date, habitat modeling in fragmented landscapes has relied on landscape composition ...
Habitat Requirements and Selection by Kelp Gulls (Larus Dominicanus) in Central and Northern Patagonia, Argentina
(Oxford University Press, 2004-01)
We analyzed habitat requirements and selection of Kelp Gulls (Larus dominicanus) breeding at 68 colonies along 2,500 km of coastline in Patagonia, Argentina. Kelp Gulls use a wide range of nesting habitats that include ...
Modeling of potential habitat suitability of Hippocamelus bisulcus: effectiveness of a protected areas network in Southern Patagonia
(Springer, 2017)
Introduction
Huemul (Hippocamelus bisulcus Molina) is the most threatened flag species of Southern Patagonia, where conservation efforts were not effective to avoid the retraction of its distribution area. Habitat quality ...
The use of native vegetation as a proxy for habitat may overestimate habitat availability in fragmented landscapes
(Springer, 2016-05-01)
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 ...
Forest loss and the biodiversity threshold: an evaluation considering species habitat requirements and the use of matrix habitats
(Brasil, 2013)
Habitat loss is the main driver of the current biodiversity crisis, a landscape-scale process that affects the survival of spatially-structured populations. Although it is well-established that species responses to habitat ...
Specific differences in habitat requirement drive responses to habitat loss and disturbance in Atlantic Forest small mammals
(Instituto de BiologiaPrograma de Pós-Graduação em Ecologia e Biomonitoramento (Pós-Ecologia)UFBABrasil, 2018-06-15)
As deforestation proceeds, habitat is lost in the landscape and the human-created matrix augments. Species that differ in their habitat requirements and tolerance to disturbance should not be equally affected
by habitat ...
Selecting compact habitat reserves for species with differential habitat size needs
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
We propose a model for the design of protected habitat reserves, which maximizes the number of species represented at least once in a limited set of reserved sites or parcels. Most models for reserve design do not differentiate ...
