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 ...
Responses of Chilean forest birds to anthropogenic habitat fragmentation across spatial scales
Although it is recognized that anthropogenic forest fragmentation affects habitat use by organisms across multiple spatial scales, there is uncertainty about these effects. We used a hierarchical sampling design spanning ...
Pérdida de hábitat y su relación con la extincion de especiesHabitat loss and its relation to species Extinction
(Bogotá : Universidad de Ciencias Aplicadas y Ambientales, 2003, 2019)
Land use intensification differentially benefits alien over native predators in agricultural landscape mosaics
Aim: Both anthropogenic habitat disturbance and the breadth of habitat use by alien species have been found to facilitate invasion into novel environments, and these factors have been hypothesized to be important within ...
Do beavers improve the habitat quality for Magellanic Woodpeckers? ¿Los castores mejoran la calidad del hábitat para el pájaro carpintero magallánico?
The effect of the disturbances caused by the American beaver (Castor canadensis), introduced to the Cape Horn Biosphere Reserve, on species of birds that are forest habitat specialists is poorly understood. Using telemetry ...
Effects of habitat fragmentation on seed quality of Lapageria rosea Efecto de la fragmentación del hábitat sobre la calidad de las semillas en Lapageria rosea
Habitat fragmentation is commonly associated to a reduction in plant fitness, because the reduction in the number of seeds produced. However habitat fragmentation might also affect plant fitness through a reduction in the ...
Habitat use by Oncifelis guigna and Pseudalopex culpaeus in a fragmented forest landscape in central Chile
Native forests in Chile have been replaced by exotic plantations, generating a mosaic of forest fragments immersed in a matrix of plantations and farms. This landscape change could affect habitat availability for native ...
Reproductive consequences of flower damage in two contrasting habitats: The case of Viola portalesia (Violaceae) in Chile
(Sociedad de Biologia de Chile, 2012)
The indirect impact of flower herbivory on plant reproduction depends on the pollination environment, particularly on the presence or absence of pollinator species with the ability to discriminate damaged from undamaged ...
Increased resource availability prevents the disruption of key ecological interactions in disturbed habitats
(Ecological Society of America, 2017)
© 2017 Fontúrbel et al. Anthropogenic disturbance can modify habitat structure and resource availability, potentially disrupting ecological interactions. This issue may be critical for pollination and seed dispersal, which ...
