Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Urbanisation and human activities influence the co‐occurrence of red squirrels Sciurus vulgaris and meso‐carnivores in Berlin, Germany

Wildlife Biology, EarlyView.
Urban expansion is a major driver of habitat fragmentation, shrinking wildlife habitat, and restricting wildlife movements and activity patterns. In this novel environment, species must adapt to the new composition of wildlife communities. For example, red squirrels Sciurus vulgaris are commonly found in urban environments, while their potential ...

Epiphytic Lichens in Salt Flats as Biodiversity Refuges in Reserva Ecológica Arenillas

Diversity
The mangrove biome is a highly productive system globally, with flora and fauna adapted to significant saline influence, where salt flats coexist alongside these systems, emerging over sands and muds with high salinity and sparse vegetation.

Lichen Striatus and Lichen Planus

Journal of Investigative Dermatology, 1948
The simultaneous occurrence of lichen striatus and lichen planus is extremely rare and the resemblance of one dermatosis to the other is (in some instances) so pronounced that a differential diagnosis, based on clinical manifestations, is difficult.

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Parturition timing and the pre‐ and post‐partum behaviour of female moose assessed using animal‐borne video and movement‐based approaches

Wildlife Biology, EarlyView.
Limited information on moose calving behaviour, including parturition timing, cow‐calf interactions, and pre‐ and post‐partum movement patterns hinder our ability to define calving phenology and habitat use. GPS‐collars were deployed on 89 female moose over five years, including eight collars equipped with animal‐borne video and environmental data ...

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

Wildlife Biology, EarlyView.
Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.

Risk Factors for Cutaneous Immune‐Related Adverse Events in the Japanese Population: A Retrospective Single‐Center Cohort Study

The Journal of Dermatology, EarlyView.
ABSTRACT Immune checkpoint inhibitor (ICI)‐driven alterations in the immune system can induce immune‐related adverse events (irAEs). Cutaneous irAEs are notable for being the most common and for their early onset; however, the risk factors underlying their development and severity remain unclear. In this study, we retrospectively analyzed 1224 Japanese

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...
