This work was done on 1996 and 1997, and presents an extremely valuable baseline to compare the recent and future changes on the insular shallow habitats of the Azorean islands. We examined the structure of the molluscan communities of the macroalgae Halopteris scoparia in São Miguel Island (Azores, Portugal). This island was chosen because it is the largest and the most populated of the archipelago, with polluted sites which...
Global maps of soil temperatureNARA Subscribed
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1‐km 2 r...
Recovery of Arapaima sp. populations by community‐based management in floodplains of the Purus River, AmazonNARA Subscribed
In the present study a unique dataset on population abundance in various community‐based management ( CBM ) and non‐ CBM areas is analysed to address the question of whether CBM can recover overexploited populations of Arapaima sp. in river‐floodplain ecosystems. All non‐ CBM areas possessed depleted Arapaima sp. populations with a mean density of 0·01 individuals ha −1 . Arapaima sp. population densities in all CBM areas chan...
Climate effects on amphibian distributions depend on phylogenetic resolution and the biogeographical history of taxaNARA Subscribed
Aim Disentangling the effects of climate and historical factors on biodiversity distribution remains a challenge for biogeographers. Here, we provide an analytical framework to discriminate the contributions of contemporary climate and the biogeographical history of taxa to the geographical distributions of phylogenetic lineages. Furthermore, we evaluate the constraint that the biogeographical history of clades exerts on the a...
