Summary After an absence of almost 100 years, the Eurasian lynx Lynx is slowly recovering in Germany along German–Czech border. Additionally, many reintroduction schemes have been discussed, albeit controversially, for various locations. We present a habitat suitability model as basis further management and conservation efforts aimed at recolonization population development. developed statistical using logistic regression to quantify factors that describe home ranges fragmented landscape. As...
We demonstrate by means of simple, noninvasive methods (analysis satellite images, field observations, and measuring “deer beds” in snow) that domestic cattle ( n = 8,510 308 pastures) across the globe, grazing resting red roe deer 2,974 at 241 localities), align their body axes roughly a north–south direction. Direct observations revealed animals orient heads northward when or resting. Amazingly, this ubiquitous phenomenon does not seem to have been noticed herdsmen, ranchers, hunters....
Background White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America 2006, where over million died since then. In Europe, G. destructans was identified France 2009. Its distribution, infection dynamics, and effects on Europe are largely unknown. Methodology/Principal Findings We screened hibernacula Czech Republic Slovakia for presence during winter seasons 2008/2009 2009/2010. 2009/2010, we found...
Resting and grazing cattle deer tend to align their body axes in the geomagnetic North-South direction. The mechanism(s) that underlie this behavior remain unknown. Here, we show extremely low-frequency magnetic fields (ELFMFs) generated by high-voltage power lines disrupt alignment of bodies these animals with field. Body orientation roe was random on pastures under or near lines. Moreover, exposed various directly beneath vicinity trending directions exhibited distinct patterns alignment....
Red foxes hunting small animals show a specific behaviour known as ‘mousing’. The fox jumps high, so that it surprises its prey from above. Hearing seems to be the primary sense for precise location in high vegetation or under snow where cannot detected with visual cues. A preparing jump displays degree of auditory attention. Foxes on prowl tend direct their roughly north-eastern compass direction. When are and cover, successful attacks tightly clustered north, while other directions largely...
Several mammalian species spontaneously align their body axis with respect to the Earth's magnetic field (MF) lines in diverse behavioral contexts. Magnetic alignment is a suitable paradigm scan for occurrence of magnetosensitivity across animal taxa heuristic potential contribute understanding mechanism magnetoreception and identify further functions magnetosensation apart from navigation. With this mind we searched signs dogs. We measured direction 70 dogs 37 breeds during defecation...
Abstract Survival and cause‐specific mortality rates are vital for evidence‐based population forecasting conservation, particularly large carnivores, whose populations often vulnerable to human‐caused mortalities. It is therefore important know the relationship between anthropogenic natural causes evaluate whether they additive or compensatory. Further, relation survival environmental covariates could reveal specific landscape characteristics influence demographic performance. We used...
While magnetoreception in birds has been studied intensively, the literature on bony fish, and particularly non-migratory is quite scarce. We examined alignment of common carps (Cyprinus carpio) at traditional Christmas sale Czech Republic. The sample comprised measurements directional bearings 14,537 individual distributed among 80 large circular plastic tubs, 25 localities Republic, during 817 sampling sessions, seven subsequent days December 2011. found that displayed a statistically...
Abstract Introduction Landing flight in birds is demanding on visual control of velocity, distance to target, and slope descent. Birds flying flocks must also keep a common course landing order avoid collisions. Whereas the wind direction may provide cue for landing, nature indicator under windless conditions has been unknown. We recorded analysed directions 3,338 14 species water eight countries. Results show that preferred direction, independently from which have arrived, along north-south...
Abstract A population of Eurasian lynx Lynx was established by reintroductions in the Bohemian Forest Ecosystem 1970s and 1980s. The most recent information on status indicates that distribution has stagnated since late 1990s, for unknown reasons. We assessed availability suitable habitat along Austrian–German–Czech border, hypothesized Bohemian–Bavarian is not equilibrium with suitability. Based global positioning system data from 10 radio-collared lynx, we used a maximum entropy approach...
Our study aimed to determine morphometric data for wild boar (Sus scrofa) in various areas of the Czech Republic and potential influence environment on its body measurements. Three localities with varying agricultural systems overall landscape structure were selected. Hunted boars measured height at withers, length, ear metatarsal length weight (depending circumstances, either dressed head, without or undressed). We also determined age hunted according teeth development. During 2003-2007, a...
Introduction This paper investigates the links between deforestation and key economic, social, environmental, geographical variables. We focus on per capita GDP, total forest cover, population across a diverse sample of countries from five continents for last three decades. Methods study utilizes regression model using panel data to show impact social variables deforestation. Also, set dummy is introduced in paper. To enable investigation, we use dummies capture their influence. The random...
Introduction The paper aims to examine the prospects of algae production as a source protein in European market. As well highlighting promising developments food industry Europe. By 2027, it is expected that market will be worth approximately USD 300 million. Methods We conducted thematic analysis and synthesis scientific literature conceptual documents at level. Results studies reviewed show nutritional value products can increased by using algae. for should encouraged Europe because viable...
Vallo, P., Benda, Červený, J. & Koubek, P. (2012). Conflicting mitochondrial and nuclear paraphyly in small‐sized West African house bats (Vespertilionidae). — Zoologica Scripta , 42 1–12. Hybridization between species may result introgression of DNA from one to another. Phylogenetic inference, therefore, not recover true evolutionary relationships. In bats, there are only a few reported cases introgressive hybridization. House genus with obscure phylogeny taxonomy, caused mainly by...
Spontaneous magnetic alignment (SMA), in which animals position their body axis fixed alignments relative to field lines, has been shown several classes of vertebrates and invertebrates. Although these responses appear be widespread, the functional significance sensory mechanism(s) underlying SMA remain unclear. An intriguing example comes from observations wild red foxes (Vulpes vulpes) that show a ~fourfold increase hunting success when predatory 'mousing' attacks are directed toward...
Abstract Magnetic alignment ( MA ) results from the preference of animals to align themselves along field lines geomagnetic field, a behavioural expression magnetic sense. is well documented for ruminants and might demonstrate general sensory ability among artiodactyls. We measured body‐axis in 1614 foraging or resting wild boars Sus scrofa , 1849 boar beds, 1347 warthogs Phacochoerus africanus found highly significant north–south preference. The was only common denominator all observations....
