Hunting-based data (e.g., hunting bag statistics) is an important source of information to overcome the financial constraints imposed to long-term monitoring. Here, taking advantage of three decades (1989–2022) of hunting bag statistics of wild mammals in Portugal, we present the trends and discuss the issues regarding nine game species (five wild ungulates, two carnivores and two lagomorphs). Our results show that hunting bag statistics mirror the general population trends of wild mammal populations at a national scale. The data reflects the increase in number and distribution of roe deer, red deer and wild boar, and the recent expansion experienced by the Egyptian mongoose. The decline in the numbers of European wild rabbit and Iberian hare harvested are also noticeable. Hunting-based data have been used in several research contexts; however, this information is usually affected by geographical, temporal and recording bias. Portugal is no exception. Engaging the interested stakeholders is pivotal to ensure data quality. By reporting reliable and systematically collected hunting data, game managers and wildlife researchers will be able to better understand the main drivers of population dynamics, adjust hunting bags towards sustainable yield and assess the ecological and socio-economic relevance of the hunting sector.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By means of DNA metabarcoding analysis of faecal samples, we investigated the diet of Alpine ibex (Capra ibex), a mountain ungulate characterised by strong sexual dimorphism and segregation, and analysed differences between male and female diet. Despite a low level of selectivity, we found differences in the diet of males and females that consumed different plant in different quantities. Differences were maintained during both spring and summer. Males tended to feed more on plants richer in fibres (i.e., grasses and sedges) and showed stronger seasonal differences while females consumed more digestible plant families (i.e., forbs). Differences in diet between male and female Alpine ibex are compatible with the strong sexual dimorphism and segregation typical of the species and with female reproductive constraints. These results also show that conservation actions have to take into account different ecological needs of males and females in species characterized by sexual dimorphism and segregation.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the patterns and predictors of HEC is crucial to identify priority areas for mitigation efforts. Accordingly, a study was conducted across the forest divisions of Tamil Nadu, India. We collected HEC data for 2016–2021 from the forest department compensation database maintained in forest divisions. Our analysis encompassed division-wise, crop-wise, conflict-wise assessments, temporal analysis and conflict risk modelling (CRM). We divided the forest divisions into 4 different zones based on the variables that likely influence HEC. The results revealed that conflict frequency was higher in the forest range Denkankottai, located in the Hosur division, which falls under Zone 1. HEC was higher from November to January in correspondence with the cropping season. Elephants primarily damaged millet (ragi) (Eleusine coracana), with n = 2,182, particularly during November and December, followed by banana (Musa genus) with n = 1,690. The CRM predicts that the southwest and northwest regions of Tamil Nādu had higher conflict risks and area coverage of medium and high conflict risk zones as 17,025 km2 and 3521 km2, respectively. The CRM revealed that the most significant variables in predicting conflict risk are the annual mean temperature, human modification index, and digital elevation model. Areas with higher conflict risk were closer to forest cover, croplands, roads, and water bodies. These regions typically had lower terrain ruggedness, higher human modification, lower temperatures, and dense vegetation. The present study’s findings underscore the need for a comprehensive and multidimensional approach to managing HEC, which is crucial for fostering coexistence between humans and elephants in the region.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional technologies leveraging bird vision and hearing often lose their effectiveness over time as birds become habituated to these stimuli. To address these challenges, our study introduces a novel countermeasure technology based on neurophysiology. The human brain reacts to flickering light, which can cause symptoms like headaches, nausea, and dizziness. In extremely rare cases, 15 Hz flickering red light can even lead to epilepsy. Not only humans, but chickens also suffer from 14 Hz flickering light. This led us to consider the possibility that similar flickering light stimuli could be applicable to bird management. In our experiments conducted during the day, we used long-range flashlights. White flickering light had no effect on bird escape behavior. However, when cellophane film was attached to the flashlights to restrict the wavelength, the emitted red light induced escape behavior in birds. Additionally, employing two types of flashlights to generate flickering red + blue or red + green lights elicited escape behavior. However, the blue and green combination proved to be less effective. The most intense flickering frequency for crows was 15 Hz. These results are highly similar to those found in human neurophysiology, showing that red light alone and the combination of red and blue lights have the most significant impact on the brain. By measuring the flight initiation distance (FID) of birds, we found that illuminated areas had a significantly higher FID (137 m) compared to non-illuminated areas (12 m). These findings suggest that applying principles of human physiology to wildlife management can offer new solutions for bird damage control.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Management of take is challenging since the life cycle of migratory waterfowl consists of several stages distributed among several locations, with possible spatio-temporal overlap among populations with differing population trends. Successful harvest management in such situations requires knowledge about the connections between breeding and non-breeding locations, and where birds are harvested. Breeding populations of Eurasian wigeon (Mareca penelope) are declining in Finland, underlining the need for more effective harvest management. Relative proportions and temporal distribution of local breeding birds and migrants from a larger Russian breeding population within the Finnish hunting bag has been unknown to date. We studied spatio-temporal origins of Finnish harvested wigeon by measuring stable-hydrogen (δ2H) isotope values from legally harvested birds. We modelled the changes in δ2H values of the feather samples within the hunting season using Gaussian processes and found that the origin of harvested wigeon in Finland changed during the hunting season and differed by age and sex. In juveniles and adult females but not in adult males, origin of harvested birds shifted from local and possibly western Russian birds to more long-distance migratory birds during the harvest season. These patterns likely reflected sex- and age-specific differences in migratory behaviour of Eurasian wigeon in the East Atlantic flyway, which can be used to guide future management and conservation of this species through the implementation of spatio-temporal harvest regulation.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parasite is now established in Europe and, while not present in all raccoon populations, it is currently expanding its range. Understanding the geographic distribution of the roundworm is a necessity for public health. Here, we report the first detections of the raccoon roundworm from Luxembourg. We used genetic techniques to test whether the roundworm originated from a distinct introduction event or entered the country by natural dispersal. We detected two roundworms in a raccoon that was road-killed in Echternach, northeastern Luxembourg. Furthermore, in a wildlife rescue centre, roundworms were detected in the latrine of an enclosure containing seven raccoons. Using different genetic techniques, we showed the Echternach roundworms to originate from the nearest German population, while the rescue centre roundworms were genetically distinct. By genotyping the host from a roundworm DNA extract, we identified a raccoon originating from southwest Luxembourg as the host of at least one roundworm. Roundworms are thus colonising Luxembourg both by natural dispersal and from an introduced population. The (potential) hosts all originated from the local population, suggesting that imported/introduced roundworms have already spread to the local raccoon population. Authorities should act as though the parasite is already widespread in the country, raising awareness among the public and individuals with occupational contact with raccoons.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To contribute in filling this knowledge gap we (1) compare the effectiveness of a suite of attractants in detecting widely distributed mammals in Europe and (2) evaluate the cost-effectiveness of these attractants, by calculating the costs associated to reach a specific monitoring objective. We conducted a large-scale field experiment across four study areas in central and northern Italy, encompassing a variety of environments, from lowland forest to alpine beech forest. We focused on comparing the following low cost and readily available attractants: sardines, peanut butter, a commercial lure and we used a camera with no attractant as control, collecting data on a suite of small to large mammals. We found that for seven of our 13 target species detectability varied with the type of attractant used. Specifically, sardines proved to be the most effective attractant for canids and the porcupine, peanut butter was most effective for mustelids but was avoided by the roe deer, whereas the commercial lure was the most effective with red deer. Through a power analysis combined with a cost function analysis we were able to show striking differences in the cost-effectiveness of the different methods, sometimes in the order of magnitude of tens of thousands of euros, which strongly emphasizes the critical importance played by the choice of whether to use an attractant or not and the type of attractant to be used.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, we employed binary species distribution maps to determine the extent of overlap between 125 protected areas, 27 wildlife refuges, and 15 national parks and species distribution, quantifying the proportion of these areas encompassed by their distribution. We found that under the SSP585 scenario, 174 bird species could experience a 319% expansion in suitable habitats, while 220 species could decline by 57.1%. Among plants, 16 species are projected to grow by 40.3%, whereas 141 species may decrease by 68.8%. Reptiles could experience an increase of 279.1% in 24 species, with a 66.6% decrease in 48 species, while mammals may witness a significant increase of 147.3% in 5 species, but a 71.8% decrease in 15 species. Also, under the SSP585 scenario, in national parks, bird coverage declines from 32.2% (current) to 19.9%, plants from 24.2 to 13.2%, reptiles from 18.4 to 6.8%, and mammals from 17.7 to 10%. In wildlife refuges, birds decrease from 9.7 to 5.7%, plants from 10.9 to 4.6%, reptiles from 12.9 to 2.5%, and mammals from 7.4 to 4.3%. In protected areas, birds drop from 29.3 to 20.4%, plants from 27.7 to 12.5%, reptiles from 18.7 to 9.7%, and mammals from 24 to 12.1%.
