Abstract The wild population of fallow deer in Central Europe has grown considerably over the last decade. However, information on feeding habits this alien species relation to indigenous red or roe deer, areas their co-occurrence, is scarce. A prevailing view maintains that food-niches are distinct, although direct comparative studies have not been carried out. Therefore, aim research was compare diets fallow, red, and same habitat. Research based rumen contents 242 animals hunted...
The diet of the golden jackal (Canis aureus) was studied in 2002 and 2003 Park Britannia (ca. 4000 ha) central Israel. aim study to understand kinds anthropogenic food that allow jackals be present at a high density. scats (396 total) were classified by season: summer (June–September) or autumn (October–November) as well origin from either southern northern part area, which experience different levels human pressure. main category ungulates (39.4% frequency occurrence), 80% domestic animals...
Although drive counts are frequently used to estimate the size of deer populations in forests, little is known about how counting methods or density and social organization species concerned influence accuracy estimates obtained, hence their suitability for informing management decisions. As these issues cannot readily be examined real populations, we conducted a series 'virtual experiments' computer simulation model evaluate effects block size, proportion forest counted, density,...
Abstract Spatially heterogeneous landscapes provide solutions to the forage‐safety trade‐off when animals can access risky but energetically rewarding patches, or safer resource‐poor patches. It be advantageous for an animal secure habitat heterogeneity at a broader scale in order able dynamically adjust finer use through time. We tested hypothesis of optimization tactic hunted red deer ( Cervus elaphus ) population following large accidental forest fire. used telemetry data and fitted...
Abstract Under an optimal foraging scenario, prey selection would be expected to occur when food resources are abundant. A positive frequency‐dependent elicit switching the abundance of main decreases, potentially favouring community resilience effects intensive, selective predation on a single prey. We assessed whether by wolf Canis lupus occurred in two areas hosting abundant populations wild ungulates, one northern (Słowiński National Park, Poland) and other southern (Maremma Regional...
The influence of population density sika deer (Cervus nippon) on their activity, habitat use, and habitat-related group size was studied in the area Japan's Tanzawa Mountains early winter. percentage active higher January 1994 (a low-density period) than 1995 high-density period). pattern use differed between periods. During period, increased relative lower quality habitats. A possible mechanism implications this are discussed. Changes had a positive effect deer, though variation among types...
Abstract Red and roe deer are the most numerous cervids in Europe, they occur sympatry regions. Roe were considered to be an inferior competitor studies which co‐occurred with fallow or muntjac. Despite remarkable overlap of their ranges, there few on competition between red deer. Since interspecific interactions among ungulates often related mutual densities, current study focused effects high density numbers spatial distribution unhunted Słowiński National Park (SNP) northern Poland forest...
Several studies reported a high prevalence of SARS-CoV-2 among white-tailed deer in North America. Monitoring cervids all regions to better understand infection and circulation other populations has been urged. To evaluate exposure and/or to/by Poland, we sampled 90 red shot by hunters five hunting districts north-eastern Poland. Serum nasopharyngeal swabs were collected, then an immunofluorescent assay (IFA) detect anti-SARS-CoV-2 antibodies was performed as well real-time PCR with reverse...
Maintaining biodiversity is one of the factors determining proper functioning ecosystems, especially those with high human impact. Ground beetles, as bioindicators, are particularly valuable in understanding ecosystem responses and sustainability forest landscape management. Focusing on regeneration pine forests, this study aimed to describe ground beetle assemblages Scots natural artificial northeastern Poland. This was conducted between 2016 2018. Pitfall traps were set up for catching...
Abstract Influence of habitat type on the group size sika deer was analysed basis 2718 individuals observed in 708 groups, area where are under pressure neither from predators nor hunters. From spring to autumn, percentage largest groups open woodland higher than both clearings and closed woodland. In early winter, aggregated highest clearings, while late Besides, large morning evening (when most active) much during daytime level activity is lower). Changes food availability suggested be a...
Rising deer densities are often in conflict with human activity. Among those conflicts there is conservation of natural resources whereas the protected areas, which unhunted, known to form a hunting refuge resulting higher than surrounding hunted areas. The issue well many areas US, much less information on matter available Europe, where smaller other regions world. We studied red density, their distribution and pressure vegetation Słowiński National Park, northern Poland, whose land area...
Abstract To date, in research, the main determinants influencing animal assemblages fragmented forests have been considered to be forest island area and degree of isolation. Such a simplistic approach may detrimental effects on obtained results conclusions, since there are large number other factors determining persistence islands. In order identify these evaluate their importance, we reviewed scientific literature topic. addition area, also patch shape, edge local plant community structure...
The study examines the influence of Polish primitive horse grazing on vegetation in deciduous and coniferous old forest stands north-east Poland. It was conducted both sites two complexes located in: (i) fenced area Popielno Research Station Academy Sciences, with free-living pony [Polish (Equus ferus caballus Linnaeus, 1758)] 130-year-old stands, (ii) open 116-year-old managed (harvested) Maskulińskie Forest District, without horses. In areas are inhabited by red roe deer. impact animals...
