Abstract Wolves in Italy strongly declined the past and were confined south of Alps since turn last century, reduced 1970s to approximately 100 individuals surviving two fragmented subpopulations central‐southern Apennines. The Italian wolves are presently expanding Apennines, started recolonize western Italy, France Switzerland about 16 years ago. In this study, we used a population genetic approach elucidate some aspects wolf recolonization process. DNA extracted from 3068 tissue scat...
Summary Under increasing environmental and financial constraints, ecologists are faced with making decisions about dynamic uncertain biological systems. To do so, stochastic programming ( SDP ) is the most relevant tool for determining an optimal sequence of over time. Despite number applications in ecology, still suffers from a lack widespread understanding. The required mathematical knowledge as well absence introductory material provide plausible explanations this. Here, we fill this gap...
Abstract: Assessing conservation strategies requires reliable estimates of abundance. Because detecting all individuals is most often impossible in free‐ranging populations, estimation procedures have to account for a <1 detection probability. Capture–recapture methods allow biologists cope with this issue detectability. Nevertheless, capture–recapture models open populations are built on the assumption that share same probability, although heterogeneity among has led underestimating...
While large carnivores are recovering in Europe, assessing their distributions can help to predict and mitigate conflicts with human activities. Because they highly mobile, elusive live at very low density, modeling presents several challenges due 1) imperfect detectability, 2) dynamic ranges over time 3) monitoring scales consisting mainly of opportunistic data without a formal measure the sampling effort. Here, we focused on wolves Canis lupus that have been recolonizing France since early...
The aim of this study was to assess long-term outcome Orr-Loygue rectopexy and Delorme's procedures in total rectal prolapse management.Data were collected retrospectively from 1978 2001. Statistical analysis performed by chi-squared test Student's t -test.One hundred nine patients underwent either a (49 patients) or procedure (60 patients). Mean follow-up 88 (range, 1-300) months. In the group, overall complication rate recurrence 33 percent 4 percent, respectively. with preoperative...
Sharing space with large carnivores on a human-dominated continent like Europe results in multiple conflictful interactions human interests, of which depredation livestock is the most widespread. We conducted an analysis impact by all four European sheep farming 10 countries, during period 2010–2015. ran hierarchical Simultaneous Autoregressive model, to assess influence several ecological factors reported levels. About 35,000 (SD = 4110) kills were compensated ten countries as caused...
Wolves have large spatial requirements and their expansion in Europe is occurring over national boundaries, hence the need to develop monitoring programs at population level. Alps are defined as a functional management unit. The range of this wolf Alpine now covers seven countries: Italy, France, Austria, Switzerland, Slovenia, Liechtenstein Germany, making development joint coordinated program particularly challenging. In framework Wolf Group (WAG), researchers developed uniform criteria...
ABSTRACT Since the gray wolf was eradicated from large parts of Europe, this species has been recolonizing much its former distribution, particularly since past 30 years. Wolves benefit European legal protection through Habitats Directive and Bern Convention, reporting on evolution their populations in each country Europe is mandatory. To monitor French over long term, a standardized high‐quality methodological framework developed to analyze data noninvasively collected samples assess...
Managing large carnivores is one of the most controversial issues in wildlife conservation, as sociopolitical challenges it raises are important biological ones. Such conservation require objective components to be implemented within management decision process, particular, a reliable way estimating trends abundance. However, these species usually exhibit territoriality, low densities, and social constraints that can generate individual detection heterogeneity (IDH) methodological (sampling)...
Abstract Occupancy models were originally developed to better understand species distribution while accounting for imperfect detection. Because is not only shaped by habitat quality but also the ability of individuals reach suitable habitats, spatial dynamic occupancy have been proposed extend original framework defining that site colonisation was a function Euclidean distance occupied sites. However, all sites in landscape are equally accessible due presence barriers, corridors, etc. To...
Obtaining estimates of animal population density is a key step in providing sound conservation and management strategies for wildlife. For many large carnivores however, estimating difficult because these species are elusive wide-ranging. Here, we focus on the first Eurasian lynx (Lynx lynx) French Jura Vosges mountains. We sampled total 413 camera trapping sites (with two cameras per site) between January 2011 April 2016 seven study areas across counties obtained 592 detections over 19,035...
The wolf recovery in France dates back to 1992, following the natural range expansion of remaining Italian population since late 1960’s. Facing a high level interactions between wolves and sheep breeding, decision makers had quickly balance need for managing livestock depredations with conservation as protected species. French authorities therefore required reliable assessment changes species numbers, well monitoring on livestock, all being key variables be further included within...
Over the past 30 years, gray wolf population has recovered in France, initially to wolves from Italy passing through Alps. The is carefully monitored, but little information available on their helminth fauna, which includes parasites of public health importance: Echinococcus multilocularis and granulosus sensu lato. Capitalizing availability 911 fecal samples collected for noninvasive genetic monitoring French populations, along with intestines 15 dead wolves, presence species among others...
Deep learning is used in computer vision problems with important applications several scientific fields. In ecology for example, there a growing interest deep automatizing repetitive analyses on large amounts of images, such as animal species identification. However, are challenging issues toward the wide adoption by community ecologists. First, programming barrier most algorithms written Python while ecologists versed R. Second, recent have focused computational aspects and simple tasks...
The occurrence of wolf populations in human-dominated landscapes is challenging worldwide because conflicts with human activities. Modeling an important tool to project dynamics and expansion, help decision making concerning management conservation. However, some individual behaviors pack the life cycle are still unclear ecologists. Here we present individual-based model (IBM) while exploring lesser-known processes cycle. IBMs bottom-up models that simulate fate individuals interacting each...
A detection dog and handler team were used to recover scats in areas newly colonized by wolves outside the Alpine mountains of France between October 2018 May 2019. Survey classified as occupied a resident wolf pack (WP) or dispersers (no-WP). The efficiency monitoring targeted dog-handler was compared opportunistic trained observers. Use allowed up 99.6% time savings relative Wolf found represented 82.1% genetically confirmed samples 12 sample units (each being 10 × km) monitored both...
The efficiency of the management predations on livestock by gray wolves ( Canis lupus ) through culling is under debate. Evaluating wolf requires to simultaneously analyze effects population and repercussions these changes predation. This protocol technically difficult implement in field. To properly assess efficiency, we provided an integrated flexible individual‐based model that simulated interactions between dynamics, predation behavior management. We considered many social processes...
SUMMARY Sharing space with large carnivores on a human-dominated continent like Europe results in multiple conflictful interactions human interests, of which depredation livestock is the most widespread. Wildlife management agencies maintain compensation programs for damage caused by carnivores, but long-term effectiveness such often contested. Therefore, understanding mechanisms driving carnivore impact activities necessary to identify key actions reduce it. We conducted an analysis all...
