Ecophysiology and phylogeny of new terricolous and epiphytic chlorolichens in a fog oasis of the Atacama Desert

open access: yesMicrobiologyOpen, 2019
The Atacama Desert is one of the driest and probably oldest deserts on Earth where only a few extremophile organisms are able to survive. This study investigated two terricolous and two epiphytic lichens from the fog oasis “Las Lomitas” within the ...

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

open access: yesRemote 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 ...

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

open access: yesWildlife 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 ...

Heavy metal accumulation in Artemisia and foliaceous lichen species from the Azerbaijan flora [PDF]

open access: yes, 2006
Artemisia plants and foliaceous lichens are known to be capable of accumulating heavy metals (HM) from soil and air. These plant species are widespread on polluted sites of Azerbaijan.

Field test of assumptions for using line transect distance sampling on rock ptarmigan

open access: yesWildlife Biology, EarlyView.
Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.

New species or interesting records of foliicolous lichens : 7., Calenia flava (Ostropales: Gomphillaceae) [PDF]

open access: yes, 2000
Calenia flava spec. nova from Papua New Guinea is described and illustrated. The new species is closely related to C. phyllogena but differs in the larger apothecia with yellow disc and the abundance of sterile thallus ...

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

open access: yesWildlife 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 ...

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

open access: yesWildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Cliffs support lichen communities unique from nearby forests

open access: yesBasic and Applied Ecology
Cliffs support rare, endemic, and glacial relict vegetation that may differ from vegetation in surrounding forests. Yet, cliffs are difficult to sample, and rock-dwelling lichens can be challenging to identify; therefore, cliff lichens are often excluded

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

open access: yesWildlife 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 ...
