Abstract‘Agricultural pests’ is a locution used to indicate those wild species considered as dangerous to crops. The crested porcupine Hystrix cristata is a semi–fossorial rodent considered as one of the main agricultural pests by farmers in Italy. Assessing the role of agriculture in shaping the porcupine’s space use is of great importance to develop proper management and conservation strategies. The goal of this study was to quantify the degree of habitat selection by and suitability for porcupines in Central Italy to assess the potential influence of agricultural fields on the ecology of this rodent. The habitat suitability analysis was realized using presence–only data implemented in the MAXENT Software, while the habitat selection analysis was carried out using the Jacobs’ selectivity index. Our research revealed that croplands have an important role in the overall habitat suitability for porcupines. However, during the warm period, all habitats were used according to their availability. Conversely, orchards, vineyards, and olive groves were preferred during the cold period. Our findings suggest that the use of agricultural crops in accordance with their availability during the warm season and the preference shown for orchards, vineyards, and olive groves during the cold one, highlight that porcupine–famer negative interactions may occur in the area. The implementation of proper prevention measures is therefore strongly suggested, especially during the cold period, to reduce the potential impacts on agriculture.

The habitat accommodation model (HAM) is a theoretical framework that predicts wildlife community recovery based on their habitat requirements. While post-fire habitat-related research is well documented in the Mediterranean basin, studies specifically focusing on HAM are scarce. Here, we described the small mammal assemblage in a Mediterranean area ~3 years after a fire, specifically examining three functional small mammalian categories: ground-foraging insectivorous, ground-foraging herbivorous/granivorous, and arboreal-foraging species. The study was conducted in Monte Pisano (Italy), where fire burnt ~12 km2 in September 2018. A stratified random sampling was adopted, basing on burnt status and forest type. In each of the 50 sites, during late spring-summer 2021, 12 hair-tubes were deployed, and collected hairs were taxa-attributed based on morphology. A presence/absence dataset was built, and db-RDA was used to explore assemblage composition, and single-species occupancy models to test specific hypotheses. The relative abundance of ground-foraging herbivorous/granivorous was higher in the burnt area, characterised by a dense undergrowth, which could be related to anti-predatory strategies and food opportunities. Insectivorous could be in a recolonisation phase, masking their earlier absence, which could explain why their abundance was not associated with any factor tested. Arboreal-foraging species were associated with forest type, indicating a primary role for tree cover and other factors such as rocky cover and likely in situ survival. The HAM was overall confirmed also in Mediterranean basin ecosystems. This may facilitate predictions about post-fire animal successions, which in turn may provide valuable insights into post-fire management practices and biodiversity conservation strategies.

Deforestation remains the most pervasive driver of biodiversity erosion across tropical forests. Understanding how species can cope with such habitat changes is particularly important along the rapidly expanding agricultural frontiers. To do so, we used a functional perspective examining small mammal responses to habitat loss, fragmentation, and degradation across the ‘Arc of Deforestation’ in the Southern Brazilian Amazon. Small mammals were surveyed using a combination of conventional and pitfall traps across 20 forest fragments—ranging from 42 to 4743 ha—in addition to two relatively continuous forest sites (> 7000 ha). These fragments lie isolated by a cattle pasture matrix of varying grazing intensity. We then analysed taxonomic and functional diversity patterns—represented by Simpson Diversity and Rao Quadratic entropy indices—in Generalised Linear Models containing local- to landscape-scale predictors of variation. Further, we used a functional trait composition approach based on community-weighted mean trait values to depict and predict small mammal functional variations across this degradation gradient. From a total of 847 individuals recorded belonging to 24 taxa, functional responses tended to follow the taxonomic diversity, both increasing with fragment area. The functional dimension further was promoted by low fire-related disturbance. Functional trait composition was mainly driven by habitat quality, represented by tree density, arthropod biomass, and fire-related disturbance. Our results reinforce that small forest fragments sustain depauperate small mammal assemblages both taxonomically and functionally. Accounting for habitat quality further allows for boosting the persistence across functional groups. Our findings can be used to improve the efficiency of management practices thereby maximising the multiple dimensions of small mammal diversity and their associated ecosystem services across tropical deforestation frontiers.

In south-western Germany, a territorial single male golden jackal (Canis aureus) was repeatedly photographed showing social interaction with a red fox (Vulpes vulpes) female and her cubs. This unusual behaviour was documented in two subsequent years (August–September 2020 and May–August 2021). The interspecific actions are not limited to encounters of the two species but include interactions such as feeding and related sociopositive behaviours. Thirty-two observations with both species appearing together were recorded within the study period. The observed behaviour raises questions about the coexistence of both species and on interspecific behaviour of wild canids in general. Social isolation of the observed male golden jackal could be one of the potential drivers for the interaction, as Germany is at the current edge of golden jackal distribution in central Europe.
