Increases in species richness cause decreases in phylogenetic diversity in Mediterranean and Temperate plant assemblages

open access: yesEcology, Volume 107, Issue 4, April 2026.
Abstract The relationship between taxonomic and phylogenetic diversities remains underexplored. Our goal was to determine whether a causal link exists between species richness and phylogenetic diversity and to determine the direction of this relationship.

Bioclimatic modelling in the holocene and in future warming scenarios in Arbutus unedo L. [PDF]

open access: yes, 2018
Growing forests wildfires in Portugal are an increasing concern since forests in the Mediterranean region are vulnerable to recent global warming. Long-term negative effects are expected on the vegetation with the coming increasing drought.

Detecting and predicting spatial and interannual patterns of temperate forest springtime phenology in the eastern U.S. [PDF]

open access: yes, 2002
We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993.

Butterfly abundance in a warming climate: patterns in space and time are not congruent [PDF]

open access: yes, 2010
We present a model of butterfly abundance on transects in England. The model indicates a significant role for climate, but the direction of association is counter to expectation: butterfly population density is higher on sites with a cooler climate ...
