Urban Science, Journal Year: 2025, Volume and Issue: 9(2), P. 27 - 27

Published: Jan. 27, 2025

Populations of the European hare (Lepus europaeus Pallas) have declined in agricultural areas throughout Europe, primarily due to habitat loss caused by industrialization agriculture. The growth cities displaces native habitats, and a decline densities would be expected also cities; however, several medium-sized mammals thrive urban areas. In this study, hares two Danish cities, Aalborg Aarhus (approx. 145,000 300,000 citizens, respectively), were monitored using combination citizen science thermal spotter. Citizen reports (in all 1874) highest center city (26 33 locations per km2). Hare observation significantly with increasing distance center. Breeding recorded both cities. spotter proved useful spot it did not draw attention as spotlights normally used detect light reflected from hares’ eyes. Based on spotted at 12 where citizens had reported hares, 40.3 (±10.8 SE) km2 estimated. awareness for biodiversity pesticides allow wild plants established lawns, which benefits hares.

The aim of this work was to characterize the quality meat from hares (Lepus europaeus Pallas), namely, fatty acid content, health lipid indices, and instrumental, histological, sensory profiles by gender muscle type (Longissimus dorsi/LD vs. Semimembranosus/SM). ΣPUFA/Σ SFA higher for males, with an average value 1.62/1. Σn6/n3 ratio elevated a mean 5.34/1. essential acids were 41.94%, desirable 77%, polyunsaturation index 6.09. Moreover, atherogenic 0.72, thrombogenic 0.71, hypocholesterolemic/hypercholesterolemic (h/H) 3.30, nutritive 1.35. After analysis, LD muscles showed scores in males overall appreciation (4.20 3.95) but females SM (4.14 4.00). Shear force influenced between connective tissue, proportion collagen protein related number fibers. Muscle tissues are inversely proportional, their is indicator textural mechanical properties analyzed samples.

Fallow deer is one of the most widespread alien mammals in Europe. We documented response roe population shortly after fallow was introduced to a hunting ground central Poland. Mean density dropped from 17.6 ind./100 ha 10.5 species introduced. In reference area, where absent, did not change analogue study period. At both sites, mean productivity before introduction similar (1.6 juv./female). However, first 1.4, while it slightly increased 1.75. The presence influenced space use negatively, i.e., number pellet groups decreased with an increase feces. Overall, successful and grew quickly. Yet, economic impact its far satisfactory. same time, negative influence on apparent. This shows that threatening local biodiversity.

The contingent impact of wind farms on game mammal density demonstrated in a large-scale analysis of hunting bag data in Poland

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Oct. 25, 2024

Wind farms are still developing dynamically worldwide, with promising prospects for further growth. Therefore, the assessment of their impact on animals has been carried out. So far, few studies have conducted game mammals, and results divergent. Previous wind species were typically based regional research covering one or, at most, several farms. In this study, we aimed to verify effect density mammals through a large-scale analysis country level, using lowland Poland as an example. The study was hunting bag data from open-field districts. It covered seven species: roe deer (Capreolus capreolus), wild boar (Sus scrofa), red fox (Vulpes vulpes), raccoon dog (Nyctereutes procyonoides), European badger (Meles meles), polecat (Mustela putorius), hare (Lepus europaeus). We used Corine Land Cover account differences in land cover area by generalized linear mixed models. showed that agricultural landscapes, mainly herbivorous related types. These tend exhibit higher densities areas containing more natural landscape features. Conversely, mesocarnivores primarily driven abundance prey little no observable effects Only presented lower increase (for deer: estimate: - 0.05, 95% CI: 0.1-0.0; boar: 0.03, 0.11-0.05), while observed or hare. underlying reasons these relationships remain unclear require specific studies. uncertainty regarding cause did not allow energy development studied mammals.

Obecne rozwiązania prawne narzucają na koła łowieckie obowiązek szkód rolniczych wyrządzonych przez niektóre gatunkizwierzyny grubej. Wszelkie koszty tytułu ponoszą ze środków własnych, przy tendencji corocznie zwiększających się kwot zobowiązań. Na podkreślenie zasługuje fakt, iż pokrywają prawie ¾ wszystkich kraju wypłacanych rolniczych. Zgodnie prawem jedynym sposobem wspomożenia tym zakresie jest przekazanie państwo, jako prawnego właściciela zwierzyny, prawa własności zwierzyny odstrzelonej kołom łowieckim. Wpływy finansowe sprzedane tusze większości kwoty rokrocznie odszkodowań, lecz nie rekompensują kosztówtechnicznych związanych całością szacowania.

Contrary to historical data, one-fourth females breed outside forests areas, indicating high plasticity species. badgers recruitment rates have also increased. mean litter sizes these two species are positively affected by small rodent availability. dog, an alien invasive species, used be sporadically but breeds regularly (1.8 cases yearly). Nowadays, free-ranging/feral dogs not controlled culling, so they started wild (1.6 per year), a new occurrence.

The secret life of wild animals revealed by accelerometer data: how landscape diversity and seasonality influence the behavioural types of European hares

Published: Sept. 21, 2023

Abstract Context Landscape composition and configuration, as well seasonal landscape dynamics shape the behaviour, movement energy expenditure of animals, i.e. foraging, hiding or fleeing, ultimately survival. Especially in highly modified agricultural systems, it is crucial to understand how animal behaviour influenced by context develop sustainable land management concepts. Objectives We show together with affect behavioural types, accounting for different life-history events both sexes. Methods investigated 34 European hares two contrasting landscapes (a simple a complex landscape) using tri-axial accelerometer data classify animals’ into five categories: resting, moving, grooming standing upright (i.e. vigilance behaviour). tested whether amount behaviours per category changed season sex. Results During peak breeding, areas high habitat diversity rested more, moved less spent time searching resources. winter, more less. Females foraged large fields. Conclusions A particularly important during breeding season, allowing animals allocate enough reproduction. In low may not find thermal anti-predator shelter move much they would need meet their requirements. Hence, small field sizes guarantee species persistence human-altered throughout year.
