Article
Full-text available
Polyphylla ragusae (Coleoptera Scarabaeidae) is an endemic beetle restricted to the island of Sicily (Italy). This species is among the most threatened invertebrates in Italy. Currently, scientific knowledge of the distribution and habitat selection of P. ragusae is scarce, though anecdotal observations suggest that the species is primarily found i...
Article
Conservation strategies are mainly decided, also for tropical species and habitats, on the basis of studies and examples made in the temperate regions, especially in North America and Europe. Conservation strategies for tropical species are often thought to fail due to a plethora of « human dimension » reasons. These reasons are external to the nat...
Article
Full-text available
The sexually dimorphic dynastine centaurus beetle, genus Augosoma (Coleoptera: Scarabeidae), is endemic to tropical Africa where two species are found (A. centaurus and A. hippocrates). These beetles are consumed by rural populations, cause damage in plantations and are targets of insect collectors and traders. We present information on size differ...
Article
Full-text available
We re-examined the knowledge on the relationships between fauna and forest management in Italy. We focused our attention on Vertebrates, including small mammals (Rodents and Soricomorphs), bats, birds, reptiles and amphibians, and on carabid and saproxylic beetles. We found that nearly all groups respond in accordance with Angelstam’s scheme of the...
Article
Full-text available
Tropical savannah ecosystems are characterized by extensive grasslands with more or less sparse trees and thickets, and are threatened globally by anthropogenic forces. These grassland habitats house a rich and diversified fauna assemblage, with some of its conspicuous elements (for instance, small mammals) that have not been sufficiently investiga...
Article
Full-text available
In Italy, after the elevation to species rank of the Valais shrew Sorex antinorii, all collection specimens from the museums previously attributed to the Eurasian shrew Sores araneus were assigned to the former species. But no official verification of this "automatic" species attribution has ever been attempted. In our work we did the revision of 1...

Tropical regions host a large variety of animal species, representing the richest concentrations of biological diversity across the Earth [...]
Article
Full-text available
The Goliath beetle (Goliathus goliatus) is one of the largest and most commercially valuable (for collection exports) beetle species worldwide, and occurs in West and Central Africa, with polymorphic populations being found in Benin, Eastern Nigeria, and Western Cameroun. The white morph is the most commercially valuable, and therefore is actively...
Article
South Sudan's biodiversity is threatened because of a plethora of reasons ranging from weak environmental regulation, poor development planning, overexploitation of wildlife, livestock and agricultural land expansion, climate change, political and armed con ict [1]. Climate change has already caused substantial ecological issues in the country. For...
Article
One of the most crucial issues in conservation science is to predict which species are more prone to decline within a subset of taxa. Applying theoretical ecology to inform conservation science may be helpful when evaluating the effects that a decline in the prey resource may have on the communities of given predators. Mean body size of rodent-eati...
Article
Peninsular effect is an anomalous gradient in plant and animal species richness from base to tip of a given peninsula. This pattern has been studied intensely on various taxonomic groups, but with scarce attention for using standardized data. Here, using presence-absence data normalized by the field effort, the peninsular effect on the species rich...
Article
Full-text available
The assessment of habitat selection and temporal patterns of activity rhythms is paramount for wildlife conservation. Studies on behavioural ecology of wild mammals are particularly challenging in tropical areas, mostly when involving rare or elusive species. Despite being a common species in Italy, the crested porcupine Hystrix cristata is threate...
Article
Full-text available
We studied species-area and diversity-dominance patterns in fish communities of a mosaic of urban ponds (Rome, Italy). We detected 10 fish species (all introduced) in 40 isolated ponds (12.9% of the total; n = 311). The log-transformed species-area relationship (logS = 0.04 logA + 0.16) was significant. Assuming the lack of mechanisms of natural im...
Article
We report the first case of sexual interaction between two phylogenetically unrelated species (coypu Myocastor coypus and pond slider Trachemys scripta, a freshwater pond turtle), both of them non-native in the study area, a remnant coastal wetland of Tyrrhenian, central Italy (41°57'34.0''N 12°02'58.0''E). We inductively propose two different hypo...

Full-text available
Gia Lai bent-toed gecko (Cyrtodactylus gialaiensis) was firstly described in 2017, and is an endemic species with very restricted distributional range, estimated to be less than 10 km2 in coffee plantation in Gia Lai province, Central Highland of Vietnam. This species is listed as Critically Endangered (CR) in the IUCN Red List. To date, the natura...
Article
Full-text available
The genus Crocidura (Eulipotyphla, Soricidae) is the most speciose genus amongst mammals, i.e., it includes the highest number of species. Different species are distinguished by skull morphology, which often prevents the identification of individuals in the field and limits research on these species' ecology and biology. We combined species distrib...
Article
In wind-farm impact assessments, it is useful to know the level of uncertainty that characterizes some key variables used to assess the sensitivity to risk in species of conservation concern. Here, we have introduced the use of the Shannon entropy as a value of ecological uncertainty of the prediction of the risk assessment index, obtained from two...

Full-text available
In an era of environmental crises, conservation and management strategies need a new generation of applied ecologists. Here, we stimulate the next-generation applied ecologists to acquire a pragmatic mentality of problems solvers in real contexts, using the wide arsenal of concepts, approaches and techniques available in the project management (PM)...
Article
In this note we suggest the adoption of the expert-based approaches in use for threat analysis to allow an assessment of the magnitude of effort of wildlife management actions. Similar to what is proposed for expert-based quantification of threat events, in wildlife management this approach can be applied by assigning a score to the extent of the a...
Article
Full-text available
Reports of global declines in animal populations are now numerous and also include snakes, a group of animals now widely regarded as bio-indicators. A prerequisite for any conservation management plan to protect or restore snake population requires a data base that provides insight into population composition and changes. However snakes are well kn...
Article
Full-text available
Urbanization is a form of pervasive human-induced disturbance. We tested the effectiveness of Abundance/Biomass Comparisons (ABC) as an approach in detecting stress due to landscape urbanization in large small mammal assemblages obtained from pellets of Barn Owl (Tyto alba; Strigiformes). We compared three assemblages sampled in not urbanized conte...
Article
Full-text available
Adult sex ratios and age structures are important wildlife population parameters, but they have been poorly investigated in ungulate species in West African savannahs. We used line transects to investigate these parameters in 11 ungulates from a protected area in south-western Burkina Faso during the period 2010-2018. We created an empirical model...
Article
Full-text available
Venomous snakes are among the main sources of mortality for humans in rural regions, especially in tropical countries. In this study, a meta-analysis of quantitative community ecology studies on snake assemblages throughout the world was conducted in order to evaluate variation in the frequency of occurrence of venomous species and venomous individ...

Monospecific and bispecific genera are of particular interest in studies of taxonomic diversity and speciation evolution. Here, the distribution patterns of mono- and bispecific amphibians worldwide are investigated, with some discussion of on the conservation implications also presented. Based on an online database search (available from the Ameri...
Article
We report a case of structural oversimplification in a small mammal assemblage, indirectly obtained by owl pellets (central Italy), where mice (Rodentia Muridae) largely dominated both in abundance and biomass (about 95%). We hypothesise that this fact could be due to: (i) recent anthropisation, which induced both an expected increase of synanthrop...
Article
Full-text available
Checklists represent a basic tool for conservation and management of regional faunas. However, our knowledge on species composition in a territory changes over time due to species movements across borders, extinctions, introductions, as well as to new taxonomic evidence. We aimed to provide the most updated data on native and non-native species of...
Article
Full-text available
We tested whether the species linked to progressively disturbed environments differed in terms of their body size and trophic level. We used a set of mammal species from a region of central Italy (Latium), for which both a representative amount of data (> 30 records) and their habitat preferences were obtained from a regional atlas. To assess the l...
Article
Full-text available
Understanding and counteracting biodiversity losses requires quantitative knowledge on species distribution and abundance across space and time, as well as integrated and interoperable information on climate conditions and climatic changes. In this paper we developed a new biodiversity-climate database for Italy, ClimCKmap, based on the critical an...
Article
We reviewed the historical and recent data about the unexpected absence of a generalist ubiquitous mammal (Savi’s pine vole Microtus savii, Rodentia) from a large sub-regional coastal land reclaimed area of Tyrrhenian central Italy, trying to search for causes explaining it. We assessed the possible role of different factors for different sub-areas...
Article
Disturbance-sensitivity and habitat generalism are two important eco-behavioural traits of species. In this paper, we calculated these traits for a set of common mammal species using two proxies (HSrescaled for disturbance-sensitivity, and HH i , for habitat generalism) here obtained synthesizing the numbers and frequency of differently disturbed h...
Article
Full-text available
Mountains are important landforms for both biodiversity and evolution of endemism. We analyzed macro-ecological patterns of distribution and endemism of European montane (i.e. with at least 70% of range inside mountain areas) mammals. Landscape of the study area was characterized by three environmental variables: land cover, land-use, and elevation...
Article
Full-text available
Whether a species can be defined as ‘endemic’ or not, is much controversial in theoretical terms, as the concepts of ‘endemism’ and ‘area of endemism’ remain much debated across scientists. We propose that it is necessary to consider (i) an organism’s body size scale and (ii) the breadth of its distribution range if we want to define a given specie...
Article
A databank on the pellets of a widespread owl species (the Barn Owl, Tyto alba) was used in order to evaluate the differences in taxonomical composition and community metrics of small mammals (Rodentia and Soricomorpha) along an altitude gradient in Italy. The databank consisted of data from 292 sites, with altitudes ranging between -6 and 1292 m a...
Article
It is now well established that Southern European peninsulas have been major glacial refugia for temperate species during Pleistocene climatic oscillations. However, substantial environmental changes occurred also within these peninsulas throughout the Pleistocene, raising questions about the role and interplay of various microevolutionary processe...
Article
Full-text available
Animal space use patterns can be affected by the intra- and interspecific density of individuals competing for resources, with home ranges generally decreasing with increasing population density. By applying spatially explicit capture-recapture models implemented in the R package secr, we study whether home ranges of co-occurring yellow-necked mice...
Article
Mono- and bispecific genera are noteworthy compared to multispecies genera because they either may be evolutionarily older or would represent not-yet-diversified young lineages, and, being in some cases endemic to specific islands and archipelagoes, they also are of conservation concern. Here, the distribution patterns of the mono- and bispecific g...
Article
Full-text available
In this paper, some data about the presence of Apodemus sylvaticus (Linnaeus, 1758) (Mammalia Rodentia Muridae) in rocky environments of the National Park of the Sibillini Mountains are provided. Considering the available data on the distribution of A. sylvaticus in Italy, this appears to be an unusual finding, which can be explained considering th...

The reserve of biosphere of Mono river is located in the Dahomey Gap, which is the relatively arid interruption in the West African forest belt that stretches from the Accra Plains in Ghana across the Volta River through Togo to the eastern border of Benin. This West African climate discontinuity is characterized by mosaics of dense semi-deciduous...
Article
The diet of predators is influenced by local conditions (e.g., characteristics of habitat and microhab-itat, seasonality, prey availability) and therefore tends to change across time. In this paper, the diet composition of the barn owl (Tyto alba) in Italy was studied using a meta-analysis of 47 articles (cov-ering 212 independent sites, with multi...

Full-text available
Mortality of sea turtles in fisheries bycatch was studied along the coast of Togo, West Africa, in the period 2012-2015. Five species of sea turtles were observed: Lepidochelys olivacea and Chelonia mydas were the commonest species, whereas Caretta caretta, Eretmochelys imbricata and Dermochelys coriacea were much rarer. Turtles captured in fishing...
Article
Full-text available
Many practices have been proposed in conservation education to facilitate a re-connection between nature and the young digital generation in anthropized contexts. In this paper we suggest that, at least in some specific circumstances (urban and suburban areas), non-native invasive species may have a paradoxical and positive impact in conservation e...
Article
Full-text available
Although there are various check lists of Italian mammals, there is not yet a synthesis of those mammals that are endemic to Italy. Therefore, we provide for the first time a detailed review on Italian mammal endemic species including endemic taxa deserving additional studies. This review is based on the most recent taxonomic revisions obtained us...
Article
Mono-and bispecific genera are of special concern as they represent unique phylogenetic/evolutionary trajectories within larger clades. In addition, as phylogenetically older taxa are supposed to be exposed to higher rarity and extinction risk, mono- and bispecific genera may be intrinsically more prone to extinction risks than multispecies genera,...
