Protected areas are important for ecological conservation while simultaneously supporting culturally and economically valuable tourism. However, excessive visitor pressure strain operations risk human-wildlife conflict, threatening the sustainability of nature-based Thus, park managers need to know what factors underpin attendance how these might interact shape future attendance. Using a decade records from 249 provincial parks in British Columbia (BC), Canada, as well 12 years interactions (HWI) at five national BC, we modelled impacts weather conditions population growth on HWIs. We paired models with climate change scenarios generate projections HWIs will throughout century. Climate is projected result more precipitation higher temperatures, and, over this same time span, BC's expected grow substantially. Based observed relationship between weather, should anticipate marked rise visitors HWIs, especially during their respective peak seasons. These provide information required proactive management, ultimately contributing recreation tourism protected areas.

What evidence exists on the impacts of artificial light on terrestrial non-flying mammals native to Europe? A systematic map and a narrative review

Introduction Nowadays, light pollution due to the multiplication of outdoor lightings has become a worldwide disturbance for many species. A large amount scientific literature shows that this sensory stressor adverse effects on several taxa. However, existing reviews tend conclude lack primary research terrestrial non-flying mammals even if these organisms are highly nocturnal and frequently exposed artificial light.

Native prey, not landscape change or novel prey, drive cougar (Puma concolor) distribution at a boreal forest range edge

Abstract Many large carnivores, despite widespread habitat alteration, are rebounding in parts of their former ranges after decades persecution and exploitation. Cougars ( Puma concolor ) apex predator with remaining northern core range constricted to mountain landscapes areas western North America; however, cougar populations have recently started several locations across America, including northward boreal forest landscapes.

Quantifying impacts of recreation on elk (Cervus canadensis) using novel modeling approaches

Ecosphere, Год журнала: 2024, Номер 15(6)

Abstract Recreation is known to impact wildlife by displacing and sometimes contributing the extirpation of sensitive species, underscoring a need for policies that balance recreation. This especially pressing when Indigenous rights necessitate ecological integrity sustainable populations throughout traditional territories. In Cascade Mountain Range Washington, USA, harvest elk ( Cervus canadensis ) declining, concurrent with increases in Yet, nature magnitude effects recreation on are unknown, which prevents land managers from developing informed regarding management. Here, we use camera traps alongside visitation models incorporate geolocated social media quantify impacts western Washington. Random forest show detection rates relatively constant at low levels (0–11 people/day), but decrease over 41% 12 22 people/day. Activity overlap analysis also revealed shift toward increased evening activity cameras higher‐than‐average (∆ = 0.70, 95% CI 0.61–0.88; χ 2 7.79, p 0.02). Generalized additive modeling confirms more crepuscular or nocturnal locations than 10 hiker detections per day. We compare methods estimating recreation, showing model‐based estimates informative camera‐based estimates. indicates recreational intensity along immediate vicinity trails may be better predictor specific trails. stress importance examining across multiple spatiotemporal scales underscore how novel approaches can provide valuable tools develop management strategies wildlife. hope our work serve as strong example collaboration between universities, state agencies, sovereign nations broader goal mitigating negative

To crop or not to crop: Comparing whole‐image and cropped classification on a large dataset of camera trap images

IET Computer Vision, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 24, 2024

Abstract Camera traps facilitate non‐invasive wildlife monitoring, but their widespread adoption has created a data processing bottleneck: camera trap survey can create millions of images, and the labour required to review those images strains resources conservation organisations. AI is promising approach for accelerating image review, tools are imperfect; in particular, classifying small animals remains difficult, accuracy falls off outside ecosystems which model was trained. It been proposed that incorporating an object detector into analysis pipeline may help address these challenges, benefit detection not systematically evaluated literature. In this work, authors assess hypothesis cropped from using species‐agnostic yields better than whole images. We find stage classification macro‐average F1 improvement around 25% on large, long‐tailed dataset; reproducible large public dataset smaller benchmark dataset. The describe architecture performs well both detector‐cropped demonstrate state‐of‐the‐art accuracy.

ABSTRACT Türkiye, due to its position as a bridge between Asia and Europe, encompassing three distinct biogeographic regions diverse climatic conditions geographical features, exhibits the characteristics of small continent in terms biodiversity, hosting very high number mammalian species. However, information on these mammals' activity patterns co‐occurrence, specifically is limited. Our study aimed reveal daily temporal overlaps species detected using camera traps Sülüklü Lake Nature Park. The white‐breasted hedgehog was strictly nocturnal, while European badger, gray wolf, hare, wild boar, beech marten tended be nocturnal. Caucasian squirrel diurnal, roe deer diurnal. highest overlap found (∆ 4 = 0.84, 95% CI), followed by red fox 1 0.77, CI). lowest 0.081, CI) squirrel. second 0.136, occurred badger. findings have provided new detailed insights into diversity within nature park located Northwestern Anatolia. These data will support facilitate future research at understanding mechanisms coexistence this ecosystem. results obtained enable deeper examination ecosystem dynamics contribute developing strategies for biodiversity conservation.

Recreational activities have been shown to induce fear responses in carnivores, causing both spatial and temporal displacement that can cascading effects on the wider ecological community. Cougars Puma concolor are one species particularly sensitive human disturbances as they found be impacted by various forms of recreational activities. This research aimed quantify cougars southern Vancouver Island British Columbia, Canada. Fifty camera traps were deployed a systematic probabilistic sampling design data from summer season 2022 was used for analyses. We modeled cougar weekly occurrence frequency relation (hikers bikers) frequency, vehicle landscape features, using generalized linear mixed models. Temporal investigated activity pattern analysis compare patterns within recreation area restricted public access reserve. avoid occurring at sites where recreationalists frequently visited, but not frequented vehicles unpaved roads. observed minimal influence habitat features or prey availability measured information loss (AIC c scores). Activity did demonstrate significant differences daily between no‐entry reserve, suggesting lack response. These results suggest impacting – behavioral dynamics. Insights how respond help inform management policies providing mitigate negative impacts thus ensure remaining compatible with conservation efforts.
