Biodiversity loss is a major challenge. Over the past century, average rate of vertebrate extinction has been about 100-fold higher than estimated background and population declines continue to increase globally. Birth death rates determine pace or decline, thus driving expansion species. Design species conservation policies hence depends on demographic data (e.g., for risk assessments estimation harvesting quotas). However, an overview accessible data, even better known taxa, lacking. Here,...
Abstract European hedgehog ( Erinaceus europaeus ) populations are widespread across diverse habitats but declining in Western Europe. Drastic declines have been described the UK, with most severe occurring rural areas. Hedgehogs widely distributed Denmark, their status remains unknown. Fieldwork on hedgehogs has tended to focus areas, leaving ecology suburban largely unexplored, clear implications for conservation initiatives. Here, we study of 35 juvenile using radio tracking during first...
The European hedgehog is in decline, triggering a need to monitor population dynamics optimise conservation initiatives directed at this species. By counting periosteal growth lines, we determined the age of 388 dead hedgehogs collected through citizen science Denmark. overall mean was 1.8 years (1.6 for females and 2.1 males), ranging between 0 16 years. We constructed life tables showing expectancies 2.6 males. discovered that male were more likely have died traffic than females, but...
Objectives A recent study from Sweden showed that European hedgehogs may constitute a reservoir for methicillin-resistant Staphylococcus aureus (MRSA), but this host-parasite relationship remains to be investigated in other countries. In study, we therefore sought to: 1) determine the dissemination of MRSA throughout Denmark; 2) investigate determinants carriage hedgehogs; 3) potential zoonotic transmission humans; and 4) characterise detected on both phenotypic molecular level. Methods...
The global “wicked” problems we face in the 21st century call for competencies. formal education system is hard pressed to foster these competencies within science curriculum. Accordingly, argue that out-of-school can function as an alternative pathway among learners. We present four distinct community case stories on teaching environments and link them a number of key challenges linked achieving Natural history museums have been foundation centuries served basis upon which nomenclature all...
The balance of evidence strongly indicates that the ecological repercussions climatic changes are already apparent in dynamics animal and plant populations throughout terrestrial, marine, aquatic ecosystems. However, while considerable progress has been made quantifying effects such climate change on spatiotemporal shifts distribution, density, phenology, subtle as intra-annual variation behavior have ignored. Yet individual-based assessments short-term species interactions may be critical...
Objectives Low genetic diversity can lead to reduced average fitness in a population or even extinction. Preserving connectivity across fragmented landscapes is therefore vital counteract the negative consequences of drift and inbreeding. This study aimed assess composition consequently conservation status nationwide sample European hedgehogs (Erinaceus europaeus) Denmark. Methods We applied an adaptation genotyping by sequencing (GBS) technique 178 individuals from six geographically...
Abstract Studies were carried out to determine the predilection sites of Trichinella nativa muscle larvae in arctic foxes ( Alopex lagopus ) caught Greenland. The highest number per gram tissue was found muscles eyes and legs. With regard no significant differences demonstrated either between age groups or with high low total parasite burdens. Predilection comparable those recorded earlier experimentally infected caged other carnivorous species. Hypotheses on are discussed.
Abstract Population expansions of boreal species are among the most substantial ecological consequences climate change, potentially transforming both structure and processes northern ecosystems. Despite their importance, little is known about expansion dynamics species. Red foxes ( Vulpes vulpes ) forecasted to become a keystone in Europe, process stemming from population that began 19th century. To identify relative roles geographic demographic factors sources European red fox expansion, we...
Long-term surveys on Traill Island (Northeast Greenland) show that numbers of king eider (Somateria spectabilis) nests are correlated with high densities collared lemming (Dicrostonyx groenlandicus). These observations match other zoological records from this region and agree similar recorded elsewhere for arctic geese. Processes at work may be related to the fact mammalian predators focus lemmings when high, but exert higher predation pressure prey low densities. Predators seem increase...
While the determinants of animals' space use have been addressed in a large number studies, its intrasexual variability has received only limited attention. By means radiotelemetry we found body mass to influence home-range size and distance moved by adult collared lemmings (Dicrostonyx groenlandicus) northeast Greenland. Male was positively correlated with size. Distance both males females also mass, but opposite trends: male movement distances increased while female decreased. This may...
In fragmented forest landscapes, population persistence of arboreal species with limited dispersal ability may strongly depend on the quality remaining habitat. Using hazel dormouse (Muscardinus avellanarius) as a model species, we studied habitat selection at two spatial scales (home range and within home range) in intensely managed woodlands its northern distributional Denmark. We modelled level conditional probability occupancy 588 nest boxes tubes 15 forests relative to variables...
