Brown bears are one of the few large carnivore species that survived final Pleistocene wave extinctions, perhaps in part owing to their wide ecological plasticity, variety forms and polyphagia. Although brown bear has become a well-studied system, many questions remain regarding ecological, trophic genetic diversity throughout distribution. For example, knowledge about Asiatic Russian from Late...

The cerrado's flora comprises aluminum-(Al) accumulating and non-accumulating plants, which coexist on acidic and Al-rich soils with low fertility. Despite their existence, the ecological importance or biological strategies of these functional groups have been little explored. We evaluated the leaf flushing patterns of both groups throughout a year; leaf concentrations of N, P, K, Ca, Mg, S, Al...

Wetlands are ecologically and economically important ecosystems with high conservation value. Although wetland vegetation is strongly determined by abiotic factors, grazing disturbance may also be an important influence on this community. We evaluated the effects of livestock grazing on wetland vegetation in marsh and wet meadow zones in intermountain depressional wetlands in the southern inter...

Ecological systems may occur in alternative states that differ in ecological structures, functions and processes. Resilience is the measure of disturbance an ecological system can absorb before changing states. However, how the intrinsic structures and processes of systems that characterize their states affects their resilience remains unclear. We analyzed time series of phytoplankton communiti...

Mosquitoes are problematic as vectors and pests in many tropical cities, including Darwin, the principal city in the Northern Territory of Australia. To monitor peaks in mosquito populations, the Medical Entomology unit of the Health Department sets overnight CO(2) -baited traps weekly. Trap setting and retrieving, followed by mosquito counting and identification, are labor intensive. Aiming to...

The main aim of the survey was to describe the diversity and richness of Chilopoda in the selected area of the Bug River valley. The study sites were located in two regions differing in the shape of the valley, the presence of thermophilous habitats and the size of riparian forests. Pitfall traps were used as a sampling method. As a result, 444 specimens belonging to 12 centipede species of two...

The present study was conducted in 47 different riparian areas distributed throughout Denmark to investigate diversity and distributional patterns of plant communities along a lowland stream size gradient (first to fifth order). The investigated areas were representative for Danish riparian areas not in use for agricultural production. We investigated plant community richness along a stream siz...

Seagrass meadows provide important ecological services to the marine environment but are declining worldwide. Although eelgrass in north Pacific thought be relatively healthy, few studies have assessed presence of known disease pathogens these meadows. In a pilot study test efficacy methods and foundational biodiversity data Pacific, we leveraged metabarcoding environmental DNA extracted from w...

Wetland ecosystems are important habitats for the growth and survival of numerous terrestrial orchids in Europe. This study reviews current knowledge on wetland vegetation Central Balkans. The orchid flora was analyzed from taxonomic, phytogeographical, ecological conservation aspects. most taxa include two Balkan endemics (Dactylorhiza cordigera subsp. bosniaca D. kalopissi macedonica) three s...
