Potential of nitrogen-fixing symbiotic systems for revegetation strategies of calcareous quarries in Mediterranean conditions [PDF]

open access: yes, 2006
Anthropogenic degradation activities (overgrazing, deforestation, quarry exploitation¿) together with a long dry and hot summer, with scarce, erratic but torrential rainfalls, is a major threat to Mediterranean ecosystem sustainability.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

open access: yesIbis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.
