PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

Ecography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Age‐related trends in niche position and specialization in Neotropical vertebrates

Ecography, EarlyView.
Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

Stochastic and deterministic processes influencing mountain mire diatom communities across spatial scales

Ecography, EarlyView.
Understanding how deterministic and stochastic processes influence the shape of microorganism community assembly across different spatial scales is essential for disentangling biodiversity patterns. Mires are nutrient‐poor and heterogeneous wetlands that form isolated habitats supporting highly diverse diatom assemblages, particularly in mountainous ...

Making sense of Sarkozy’s Union for the Mediterranean. CEPS Policy Brief No. 155, 7 March 2008 [PDF]

, 2008
President Sarkozy’s proposed Union for the Mediterranean (or UMed) has so far been poorly conceived and, to say the least, awkwardly presented politically. However this does not mean that nothing good can come of it.

Plant adaptive strategies respond to environmental change across European grassland habitats

Ecography, EarlyView.
Grassland ecosystems are facing rapid and ongoing change driven by intensified land‐use and accelerated climate change, highlighting the urgent need to understand their potential adaptation and response to environmental change. We analyzed data from 52 980 vegetation plots spanning all major grassland habitats in Europe (including alpine, rocky, sandy,

Simulating past and future refugia for temperate trees in northern Italy

Ecography, EarlyView.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...

Geographic biases and gaps in the sampling of plant–pollinator networks

Ecography, EarlyView.
Plant–pollinator interactions are essential for maintaining biodiversity and supporting food production, yet inferences drawn from network syntheses may be shaped by where interaction data are generated and which datasets are most reused. Here, we quantify the global distribution of published plant–pollinator networks, assess how publication rates vary
