Species–area relationships in continuous vegetation : evidence from Palaearctic grasslands [PDF]

open access: yes, 2019
Aim: Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas power laws best represent SARs.

Spatiotemporal patterns of vegetation conversion under the Grain for Green Program in southwest China

open access: yesConservation Science and Practice, 2022
China's Grain for Green Program (GGP) is the largest reforestation program in the world. Previous studies lacked targeted assessments regarding its effectiveness in vegetation conversion. Using the time series of Vegetation Continuous Fields in southwest

Is the ‘bat population’ an operational concept for statutory species conservation?

open access: yesGlobal Ecology and Conservation, 2023
In the European Union (EU), all bat species are legally protected by the Habitats Directive (HD). Especially the goal of keeping or restoring a favourable conservation status for protected species and habitats is an outstanding innovation in the law of ...

Temperature-derived potential for the establishment of phlebotomine sandflies and visceral leishmaniasis in Germany

open access: yesGeospatial Health, 2010
Climate change is expected to manifest in the shift of organisms to regions where they were not present in the past, potentially entailing previously unseen biological risks. However, studies evaluating these future trends are scarce.

How perilous are broad-scale correlations with environmental variables? [PDF]

open access: yes, 2020
Many studies correlate geographic variation of biotic variables (e.g., species ranges, species richness, etc.) with variation in environmental variables (climate, topography, history).

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Dispersal and adaptation strategies of the high mountain butterfly Boloria pales in the Romanian Carpathians

open access: yesFrontiers in Zoology, 2019
Background Habitat quality is one main trigger for the persistence of butterflies. The effects of the influencing biotic and abiotic factors may be enhanced by the challenging conditions in high-alpine environments. To better our knowledge in this field,
