ABSTRACT 1 European rabbits are considered a keystone species in the Iberian Peninsula.
Their populations have sharply declined over the past century, mainly due to habitat loss …

We propose a multivariate approach to the study of geographic species distribution which
does not require absence data. Building on Hutchinson's concept of the ecological niche …

This paper compares two habitat-suitability assessing methods, the Ecological Niche Factor
Analysis (ENFA) and the Generalised Linear Model (GLM), to see how well they cope with …

Predictive models on breeding habitat preferences of Bonelli's eagle (Hieraaetus fasciatus;
Aves: Accipitridae) have been performed at four different spatial scales in Castellón …

In the semiarid areas of the Mediterranean basin, restoration activities during the XXth
century have mainly relied on extensive plantations of Pinus halepensis, which now cover …

Predicting abundance across a species' distribution is useful for studies of ecology and
biodiversity management. Modeling of survey data in relation to environmental variables can …

The successful conservation of bird species relies upon our understanding of their habitat
use and requirements. In the coming decades the importance of such knowledge will only …

Farmland throughout the world is frequently likened to a mosaic or patchwork and this
heterogeneity is widely recognised as strongly influencing the abundance and diversity of …

Habitat preference of eagle owls Bubo bubo were examined through comparing habitat
composition around 51 occupied cliffs and 36 non‐occupied cliffs in Alicante (E Spain). We …

The Spanish Bonelli's Eagle populations have decreased markedly because of high
mortality. We recorded 424 cases of dead eagles between 1990 and 1998 in Spain which …
