Lynx in the Eye of the Camera: Presence and Activity of Eurasian Lynx (Lynx Lynx) Across Multiple Seasons and Years in the Polish Carpathian Mountains

Published: Jan. 1, 2025

Over the last century, large carnivore populations in Europe were severely depleted. By 1950s, only five of Eurasian lynx (Lynx lynx) persisted isolated ranges, including L. l. carpathicus subspecies within Carpathian Mountains. Although this population today is an important source genetic diversity for reintroduction and recolonisation, little research has focused on its occurrence activity Polish Carpathians. The main objective study was to evaluate dynamic structure across space time. We conducted a continuous 5-year (2015-2019) using camera traps how detections varied (1) years between four seasons, (2) diel periods (3) their social status. recorded 2261 20 trap locations, with 89% records one solitary individual per detection 10% females cubs, remaining 1% adult pairs. While solitaries detected all families utilised 9 locations. Based generalised linear model, increased during breeding period from January till March. Additionally, number decreased at night compared daylight (p<0.001) twilight (p<0.001). Families individuals season more active day. Our results indicate that promote conservation area, wildlife managers may consider maintaining areas limited human disturbance, especially season.

Abstract Wolves ( Canis lupus ) function as a top predator across diverse ecosystems including the sub-arctic, and they have been managed in often controversial ways. Communities scientists are increasingly supporting minimally invasive research monitoring, using trail cameras. We employed network of 15 Reconyx cameras at three monitoring areas aimed detecting spatial temporal aspects wolf occurrences within summer range Eastern Migratory Cape Churchill caribou Wapusk National Park Hudson Bay Lowlands Manitoba, Canada from 2013-2021. In this first peer-reviewed quantitative study wolves region, we found that detection events were generally consistent years. Wolf distribution was consistently positively skewed toward southern part all experienced extreme environmental conditions, with 60°C temperature, low −32°C winter to high +28°C an annual change day length >11 hours between winter. occurred most commonly spring equal frequency during night overall but selected for nighttime September, October, November shortened dramatically.
