Relating Depth and Diversity of Bivalvia and Gastropoda in Two Contrasting Sub-Arctic Marine Regions
Frontiers in Marine Science, 2019 The need to understand species distribution- and biodiversity patterns in high-latitude marine regions is immediate as these marine environments are undergoing rapid environmental changes, including ocean warming and ocean acidification. By the year 2100,

Methods in Ecology and Evolution, EarlyView.Abstract Advances in collection of environmental DNA (eDNA) through active air filtration and sampling from vegetation (leaf swabs) have demonstrated the promise of using airborne eDNA for terrestrial vertebrate surveys. However, methods are at an early stage, and we lack insights into the effect of air filtration time and the complementarity between ...

Complexity of Products: The Effect of Data Regularisation
Entropy, 2018 Among several developments, the field of Economic Complexity (EC) has notably seen the introduction of two new techniques. One is the Bootstrapped Selective Predictability Scheme (SPSb), which can provide quantitative forecasts of the Gross Domestic ...

Animal Conservation, EarlyView.The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

AnimalsNestedness in community ecology predicts that species in a species-poor site should be a subset of species of a species-rich site. A variety of ecological mechanisms have been offered to explain community nestedness; however, few studies have ...

Beta diversity of aquatic insects (Ephemeroptera, Plecoptera and Trichoptera) across stream microhabitats [PDF]
Acta Limnologica Brasiliensia: Aim We evaluated how the combination of environmental characteristics affects the beta diversity of the EPT (Ephemeroptera, Plecoptera and Trichoptera) community across stream microhabitats. Methods The samples were collected in 12 streams around the

Cladistics, EarlyView.Abstract Historical biogeography faces a persistent conceptual and methodological dilemma concerning the nature of its central analytical units. Using the recent proposal by Schultz and Cracraft (Cladistics 40, 653) as a catalyst, this article critiques the argument that causal inference necessitates the replacement of areas of endemism with barriers ...

On the meanings of nestedness: back to the basics
Ecography, 2012 The ecological concepts of nestedness and β‐diversity first appeared more than five decades ago, but there is still controversy over their precise meaning and application. Here, we focus on the concept of nestedness, the ordered loss of species along environmental or ecological gradients.

Diversity, 2020 Habitat conversion in mountain areas threatens their biodiversity. The effect on biodiversity of creating a mountain landscape with a network of forest fragments and a cultivated habitat matrix is poorly documented in China.
