Effects of habitat loss and fragmentation on the abundance and species richness of aphidophagous beetles and aphids in experimental alfalfa landscapes

European Journal of Entomology, 2008
In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, such as foliar-foraging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild interactions. We evaluated how habitat

Estimating offsets for avian displacement effects of anthropogenic impacts [PDF]

, 2019
Biodiversity offsetting, or compensatory mitigation, is increasingly being used in temperate grassland ecosystems to compensate for unavoidable environmental damage from anthropogenic developments such as transportation infrastructure, urbanization, and ...

Using the Lonsdorf model for estimating habitat loss and fragmentation effects on pollination service

Ecological Processes, 2021
One of the most important issues related to landscape ecology and ecosystem services is finding the pattern of habitat patches that offers the highest pollination in agricultural landscapes. In this regard, two processes of habitat loss and fragmentation

Effects of habitat loss on Brazilian primates: assessing extinction thresholds in the Amazon and Atlantic Forest

Perspectives in Ecology and Conservation, 2023
Habitat loss has major impacts on biodiversity. Yet, such impacts are not always linear, as there can be threshold values of habitat amount below which species become extirpated from human-modified landscapes (extinction thresholds).

Transmission loss in manatee habitats

The Journal of the Acoustical Society of America, 2006
The Florida manatee is regularly exposed to high volumes of vessel traffic and other human-related noise because of its coastal distribution. Quantifying specific aspects of the manatee’s acoustic environment will allow for a better understanding of how these animals respond to both natural and human-induced changes in their environment.

‘No Net Loss’ - Instrument Choice in Wetlands Protection [PDF]

, 2006
While not a high priority issue for most people, the public has long recognized the general importance of wetlands. Since President George H.W. Bush\u27s campaign in 1988, successive administration have pledged to ensure there would be no net loss of ...

The value of carbon sequestration and storage in coastal habitats [PDF]

, 2014
Coastal margin habitats are globally significant in terms of their capacity to sequester and store carbon, but their continuing decline, due to environmental change and human land use decisions, is reducing their capacity to provide this ecosystem ...

Critical shifts on spatial traits and the risk of extinction of Andean anurans: an assessment of the combined effects of climate and land-use change in Colombia

Perspectives in Ecology and Conservation, 2019
Climate and land-use change, raise significant threats to biodiversity, affecting species ranges worldwide. Both factors operate on different scales, so including spatial traits that allow them to be appropriately evaluated is relevant to the early ...
