Interpopulation and seasonal variations in habitat and microhabitat use of Vipera ammodytes (Linnaeus, 1758)

open access: yesActa Herpetologica
Despite the abundant data on habitat use of Vipera ammodytes, most studies are purely descriptive, merely listing the habitats in which the species is most often found.

Relationships between hydraulic traits and habitat preference for six Acer species occurring in the French Alps [PDF]

open access: yes, 2004
Xylem hydraulic properties and vulnerability to cavitation were studied in six Acer species which occur, in the French Alps, along a soil moisture gradient from the moist valleys to the drier mountain stands.

Habitat preferences of the sea urchin Paracentrotus lividus  [PDF]

open access: yesMarine Ecology Progress Series, 2012
Population structure of the sea urchin Paracentrotus lividus seems to vary depending on the habitat, as, on average, urchin density is higher on rocks, and size is larger in Posidonia oceanica seagrass. Here, we tested the hypothesis that P. lividus would choose P.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

open access: yesAdvanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Mapping the “Supply–Demand–Flow” of Ecosystem Services for Ecosystem Management in China

open access: yesAdvanced Science, EarlyView.
This study develops a “supply–demand–flow” framework clarifies how ecosystem services move between regions by distinguishing potential and actual supply and demand. Using integrated biophysical–socioeconomic modeling, nine services in China were mapped.

Notes on the larval habitat preference and microdistribution of Potamophylax rotundipennis (Insecta: Trichoptera) in a stream reach of the Börzsöny Mountains (Northern Hungary) [PDF]

open access: yes, 2002
Larval habitat preference of Potamophylax rotundipennis (Insecta: Trichoptera) was examined under natural conditions. The result of this study indicated a high preference for stone to sand and detritus, and preference for the low depth of water.

A General Approach for the Analysis of Habitat Selection [PDF]

open access: yes, 2007
Investigating habitat selection of animals aims at the detection of preferred and avoided habitat types as well as at the identification of covariates influencing the choice of certain habitat types.

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.
