Density-dependent dinner: Wild boar overuse agricultural land at high densities

European Journal of Wildlife Research, Journal Year: 2024, Volume and Issue: 70(1)

Abstract The Swedish wild boar ( Sus scrofa ) population has increased rapidly over the last decades, resulting in conflicts with human activities. Particularly, increase been challenging for agriculture as cause damage on crops and grasslands. To predict under what conditions to expect where prioritize management actions, basic knowledge about habitat space use is needed. In this study, we used data from 99 equipped GPS-collars, collected a large temporal scale throughout their distributional range southern Sweden. We investigated home size across gradients of availability density. Functional response was assessed by estimating agricultural land individual level then, population-level evaluating how changed changing availability. Finally, potential evaluated relation density, i.e., interaction between Home negatively related density both male female boar. Wild more intensively increasing when other types were less available. Our findings show that spatial behavior highly context dependent may vary considerably due landscape characteristics local conditions. boars tend overuse at high densities which strong implications wildlife management. It therefore important consider predicting Overall, study provided better understanding drivers distribution agro-forested mosaic landscapes can improve practices.

Risky behavior of Asian black bears differs between sex and season in a landscape fragmented by roads

Abstract Understanding the trade‐off between resource acquisition and risk avoidance is crucial in behavioral ecology. Differences parental investment reproductive success males females can result intersexual variations risk‐taking. Roads, a major cause of habitat fragmentation, pose significant mortality risks to animals. We investigated sex seasonal differences road‐crossing behavior home ranges Asian black bears ( Ursus thibetanus ), as an example risk‐taking mammals fragmented landscape, Ashio‐Nikko Mountains, Japan, from 2005 2023. Using GPS relocation data, we analyzed frequency road crossings range sizes applied integrated step selection analysis assess relation sex, season, type, time day. Bears generally avoided crossing roads, indicating that roads act movement barriers. During mating crossed all types had larger ranges, whereas did not cross main minor roads. hyperphagia both sexes compared season. Our findings suggest sex‐ season‐specific relates mate food acquisition: take more search for mates during season females. gated most frequently, followed by with occurring often at night than day across types.

Optimizing Vaccination Strategies against African Swine Fever Using Spatial Data from Wild Boars in Lithuania

Viruses, Journal Year: 2024, Volume and Issue: 16(1), P. 153 - 153

African swine fever (ASF) is one of the most severe suid diseases, impacting pig industry and wild populations. Once an ASF vaccine available, identifying a sufficient density vaccination fields will be crucial to achieve eradication success. In 2020–2023, we live-trapped monitored 27 boars in different areas Lithuania, which were fed at artificial stations. We built simulation study estimate probability successful as function eco-epidemiological factors. The average 32-day home range size across all individuals was 16.2 km2 (SD = 16.9). made frequent visits short durations feeding sites rather than long interposed by periods absence. A site 0.5/km2 corresponded expected rate only 20%. increased about 75% when 1.0/km2. Our results suggest that least field/km2 should used planning campaign ensure everyone population has 5–10 available inside range. Similar studies conducted other ecological contexts present today or future, with objective being context-specific relationship between boar movement patterns optimal strategy.

Agricultural damage following the recent expansion of wild boar ( Sus scrofa )—farmer perceptions and preconditions

International Journal of Pest Management, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 12

Published: Feb. 12, 2024

The wild boar (Sus scrofa) population has recently increased in Fennoscandia, leading to increasing interactions with humans, e.g. the form of hunting opportunities or property damages. These experiences may shape attitudes towards boars and affect their management. We studied among 165 farmers by means survey data. also made preliminary estimates damage costs Finland. Our analysis revealed three attitude groups farmers, emphasizing various perspectives: "hunting resource", "pest-of-concern", "ambivalent". benefits, costs, feelings, perceived development partly explained division. direct annual southeast Finland were broadly estimated be circa 990,000€ mitigation 350,000€. Reconciling differing opinions goals into a widely accepted management strategy is key precondition for sustainable coexistence. While level economic loss so far not substantial, monitoring crop damages vital. results provide valuable baseline future evaluations, as expected grow.
