Ecometric modelling assesses how the functional morphology of ecogeographic communities relates to environmental variables. This improves understanding of how the interaction between organism and environment can result in morphological adaptation. This technique has mainly been used to model paleoenvironments, but has the capacity to aid conservation by quantifying how communities are structured through space and time. Here, we test the relationship between limb proportions and the habitat ecology of South American non-human primates. There is a significant but weak fit between limb proportions and habitat, consistent with the environment exerting weak selective pressure on limb proportions. In contrast, body size and phylogeny are strongly correlated with IMI. Together, these findings suggest that habitat was a selection pressure that shaped how New World monkeys' limb proportions evolved but this selection pressure was secondary to that of body size. Research into these functional relationships is important not only to improve scientific understanding of their evolutionary pathways but also in order to aid their protection by informing conservation practices. Ensuring these species have the capacity to move with their niche is an immediate concern, as they face mounting pressure due to deforestation of the Amazon basin.

Human-induced environmental changes have dramatically changed habitats worldwide, decreasing the quantity and quality of habitats for wildlife and putting wild populations at risk. In the current study habitat suitability of the honey badger (Mellivora capensis) across its distribution range in Southern Iran was investigated. We combined presence-only field data with environmental and anthropogenic variables, generating an ensemble model of habitat suitability based on four species distributionmodels. The contribution scores of anthropogenic variables (human footprint index and village density) in the model were noticeable, indicated that honey badgers do not avoid humanmodified areas. The ensemble model further revealed large areas of low quality of natural habitats across the study area. Land use changes may have led honey badgers to settle in poor-quality habitats, where their fitness may be lower than in other available habitats. Therefore, there is a possible risk of an ecological trap due to the lack of protected high-quality habitats. Further research on honey badger fitness, in human-modified areas, is required to evaluate the hypothesis of ecological trap.

Invasive rats and mice typically arrive in novel regions through unintentional transportation aboard ocean-going vessels, which makes seaports the principal point of entry of these species. In this innovative study, we modeled the spatial distribution and abundance of two invasive rodent species (Rattus norvegicus and Mus musculus) in Paranaguá, a port city, in southern Brazil whose original vegetation cover was Atlantic Forest. Occupancy and abundance were estimated using live and pitfall traps during nine field campaigns (4,214 trap.nights) at 18 sampling sites distributed along a gradient of habitat between the port and the forest. The abundance and occupancy of both species were affected negatively by the percentage of forest cover within a radius of 1,000 m. The occupancy of M. musculus was also affected by the abundance of buildings within a radius of 100 m and by the distance to the nearest forest edge. The occupancy of R. norvegicus was related positively to the proximity of the access roads that link the port of Paranaguá with the rest of the state of Paraná. We conclude that, while the port is the point of entry for invasive rodents, neither study species was associated strongly with this area. The study identified the principal elements associated with rat and mouse occupancy, which provides the local authorities with important insights for the implementation of an effective invasive species management program in the municipality of Paranaguá. Overall, the Atlantic Forest reveals a remarkable ecosystem service and appears to act as a natural barrier to the dispersal of both rats and mice, being associated with a reduced abundance of these species and low occupancy probabilities.

Understanding the habitat-related hunting behavior of house cats Felis catus is needed to evaluate their potential predatory effect on areas they actively visit within their home range. As part of a citizen science program, 30 neutered cats from 25 households were equipped by their owners during, on average, 2 consecutive days per month between January and November 2016 with a GPS programmed to acquire fixes at 1 to 5 min intervals. Nine cats were located in rural environments, 9 in suburban landscapes, and 12 in urban habitats. For 16 of these cats, preys brought home were recorded daily. Using the recursive distribution movement-based kernel density estimator, rural cats had the largest mean home range area (3.5±0.3 ha), followed by suburban (2.1±0.2 ha) and city cats (1.4±0.1 ha). Moreover, suburban cats enlarged their frequently visited areas in April– June, which corresponded to a peak in small bird preys brought home. Our results suggest that a more diversified landscape may drive domestic cats to increase their home range by benefiting from higher numbers of exploitable areas.

As part of a citizen science program, 30 neutered cats from 25 households were equipped by their owners during, on average, 2 consecutive days per month between January and November 2016 with a GPS programmed to acquire fixes at 1 to 5 min intervals. Nine cats were located in rural environments, 9 in suburban landscapes, and 12 in urban habitats. For 16 of these cats, preys brought home were recorded daily. Using the recursive distribution movement-based kernel density estimator, rural cats had the largest mean home range area (3.5±0.3 ha), followed by suburban (2.1±0.2 ha) and city cats (1.4±0.1 ha). Moreover, suburban cats enlarged their frequently visited areas in April– June, which corresponded to a peak in small bird preys brought home. Our results suggest that a more diversified landscape may drive domestic cats to increase their home range by benefiting from higher numbers of exploitable areas.","PeriodicalId":55036,"journal":{"name":"Hystrix-Italian Journal of Mammalogy","volume":"103 1","pages":"105-109"},"PeriodicalIF":1.5,"publicationDate":"2020-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76477845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
