Extinctions of aculeate pollinators in Britain and the role of large-scale agricultural changes [PDF]

open access: yes, 2014
Pollinators are fundamental to maintaining both biodiversity and agricultural productivity, but habitat destruction, loss of flower resources, and increased use of pesticides are causing declines in their abundance and diversity. Using historical records

Dynamic modelling of the potential habitat loss of endangered species: the case of the Canarian houbara bustard (Chlamydotis undulata fuerteventurae) [PDF]

open access: yes, 2016
In this work, we apply a dynamic modelling approach to analyse the habitat loss of the Canarian houbara bustard (Chlamydotis undulata fuerteventurae). This tool allows us to assess the effects of the socio-economic and environmental interactions on the

Marked decline in forest-dependent small mammals following habitat loss and fragmentation in an Amazonian deforestation frontier [PDF]

open access: yes, 2020
Agricultural frontier expansion into the Amazon over the last four decades has created million hectares of fragmented forests. While many species undergo local extinctions within remaining forest patches, this may be compensated by native species from ...

Habitat Loss on Rondon’s Marmoset Potential Distribution

open access: yesLand, 2017
The Amazon basin is one of the most biologically diverse places on earth. However, agricultural expansion and infrastructure development have led to widespread deforestation that threatens the survival of many taxa.

Addressing climate change and development pressures in an urban estuary through habitat restoration planning

open access: yesFrontiers in Ecology and Evolution, 2023
Native habitats in Florida face dual pressures at the land-sea interface from urban development and sea-level rise. To address these pressures, restoration practitioners require robust tools that identify reasonable goals given historical land use trends,

Effects of roads on wildlife in an intensively modified landscape [PDF]

open access: yes, 2000
This paper examines the ecological impacts arising from road networks and the potential ameliorating effects of roadside habitat in a highly modified landscape. A U.K.

Habitat conversion and global avian biodiversity loss [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2003
The magnitude of the impacts of human activities on global biodiversity has been documented at several organizational levels. However, although there have been numerous studies of the effects of local-scale changes in land use (e.g. logging) on the abundance of groups of organisms, broader continental or global-scale analyses addressing the same basic ...

Systematic land-cover change in KwaZulu-Natal, South Africa: Implications for biodiversity

open access: yesSouth African Journal of Science, 2015
Land-cover change and habitat loss are widely recognised as the major drivers of biodiversity loss in the world. Land-cover maps derived from satellite imagery provide useful tools for monitoring land-use and land-cover change.

Does stress mess with rodents’ heads? Influence of habitat amount and genetic factors in mandible fluctuating asymmetry in South American water rats (Nectomys squamipes, Sigmodontinae) from Brazilian Atlantic rainforest remnants

open access: yesEcology and Evolution, 2021
Loss of developmental stability can lead to deviations from bilateral symmetry (i.e. Fluctuating Asymmetry ‐ FA), and is thought to be caused by environmental and genetic factors associated with habitat loss and stress. Therefore, levels of FA might be a

Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]

open access: yes, 2019
Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus
