StorAge Selection theory: a visual introduction
<p>This short video provides an introduction to the theory of StorAge Selection, or SAS. SAS is used to simulate material transport through complex systems, like rain water through a watershed and into a stream.</p> <p>The animations in this video were produced using mesas.py: https://github.com/charman2/mesas/</p>
Empirical tests of habitat selection theory reveal that conspecific density and patch quality, but not habitat amount, drive long-distance immigration in a wild bird
<p>Individuals that disperse long distances from their natal site must select breeding patches with no prior knowledge of patch suitability. Despite decades of theoretical studies examining which cues dispersing individuals should use to select breeding patches, few empirical studies have tested the predictions of these theories at spatial scales relevant to long-distance dispersal in wild animal populations. Here, we use a novel assignment model based on multiple intrinsic markers to quantify natal dispersal distances of Wood Thrush (<i>Hylocichla mustelina</i>) breeding in forest fragments. We show that long-distance natal dispersal in this species is more frequent than commonly assumed for songbirds and that habitat selection by these individuals is driven by density-dependence and patch quality but not the amount of habitat surrounding breeding patches. These results represent an important contribution to understanding habitat selection by dispersing individuals, especially with regards to long-distance dispersal.</p>

Island biogeography theory and the urban landscape: stopover site selection by the silver-haired bat (Lasionycteris noctivagans)
<p>Many migratory bats require forested sites for roosting and foraging along their migration path, but increased urbanization and intensive agricultural practices may reduce the availability of stopover sites. Urban forests may provide important stopover habitat, maintaining landscape connectivity in regions where the majority of natural habitat has been cleared for development. Island biogeography theory can be applied to urbanized temperate forest biomes where small urban forests represent islands separated from the larger "mainland" forest. We used acoustic monitoring during the fall migration period to investigate the use of urban forest habitat by the migratory species <i>Lasionycteris noctivagans</i> (Le Conte 1831)<i>.</i> We predicted that recorded activity would have a positive relationship with forest patch area and shape and a negative relationship with isolation from other forest patches, as suggested by island biogeography theory. We observed greater activity at larger forest patches, and although relationships for shape and isolation were not statistically supported the observed patterns were consistent with predictions. Our results demonstrate the need for more in-depth research on the habitat requirements for both migratory and resident bat species and the impact that ongoing urbanization has on local bat populations.</p>
Data from: BNPd single-atom catalysts for selective hydrogenation of acetylene to ethylene: a density functional theory study
The mechanisms of selective hydrogenation of acetylene to ethylene on B11N12Pd single-atom catalyst (SAC) was investigated through the density functional theory by using 6-31++G basis set. We studied the adsorption characteristics of H2 and C2H2, and simulated the reaction mechanism. We have discovered that H2 absolutely dissociative chemisorption on single atom Pd and formed the B11N12Pd(2H) dihydride complex and then proceed the hydrogenation reaction with C2H2. The hydrogenation reaction of acetylene onto the B11N12Pd complies with the Horiuti-Polanyi mechanism, and the energy barrier as low as 26.55 kcal mol-1. The low desorption energy of ethylene, high ethylene hydrogenation activation energy can ensure the B11N12Pd SAC has high selectivity. Meanwhile it also has a higher selectivity than many bimetallic alloy single-atom catalyst.
