Description
  • Competition amongst red deer and Apennine chamois. My duty was to record foraging movements and behavioural interactions of Apennine chamois (suckling behaviour; female-female aggressive behaviour) in Abruzzo, Lazio and Molise National Park, Italy.

Article
Full-text available
In the harsh Antarctic terrestrial ecosystems, invertebrates are currently confined to sparse and restricted ice free areas, where they have survived on multi-million-year timescales in refugia. The limited dispersal abilities of these invertebrate species, their specific habitat requirements, and the presence of geographical barriers can drastical...
Article
Full-text available
The complete mitochondrial genome of the true bug (Homoptera) Nysius cymoides (Spinola, 1837) is herein described and used for phylogenetic comparison with other species of Lygaeoidea. The mtDNA has a gene order and other molecular features typically observed in hexapods, and a long A + T-rich region, due to the occurrence of several repeat units....

Article
Full-text available
Two new mite species belonging to the genus Stereotydeus Berlese, 1901 were discovered from locations along the coast of Victoria Land, continental Antarctica. Previous records of this genus in the area under study only reported the presence of S. belli and S. mollis. Although those studies included no morphological analyses, it has since been assu...
Article
Genetic structure may be highly variable across seabird species, and particularly among those that are distributed over large geographical areas. The Adélie penguin (Pygoscelis adeliae) is a numerically dominant Antarctic seabird that is considered to be a key species in coastal ecosystems. Since the Last Glacial Maximum, penguin colonization of th...
Article
Sex identification is crucial for behavioral, ecological and conservation studies. In monomorphic bird species, traditional methods for sex assessment require potentially invasive sampling and manipulation of individuals, such as through cloacal examination. Thus, molecular methods involving non-destructive sampling are needed to reduce the stress...
Conference Paper
Full-text available
The extremely inhospitable Antarctic ecosystems confine plants and invertebrates to sparse ice-free areas. These species survived for millions of years in isolated refugia where population divergence and differentiation can occur, potentially resulting in speciation. The limited dispersal abilities of invertebrate species combined with their specif...
Article
Full-text available
Complete mitochondrial genome data are frequently applied to address phylogenetic/phylogeographic issues at different taxonomic levels in ecology and evolution. While sample preparation/sequencing is becoming more and more straightforward thanks to dropping costs for next-generation sequencing (NGS), data preparation and visualization remains a man...
Article
Full-text available
The silverfish Neoasterolepisma foreli belongs to the family Lepismatidae within Zygentoma and is well known for the peculiar habit of living in strict association with ant nests (myrmecophily). In this study, we describe its mitochondrial genome, a circular molecule of 15,398 bp including the canonical 13 PCGs, 22 tRNAs, 2 rRNAs, as well as a 403...
Article
Full-text available
The complete mitochondrial genome of the springtail Bourletiella arvalis (Fitch, 1863) is herein described and applied to a Bayesian phylogenetic analysis, inclusive of all the Collembola mitochondrial DNAs sequenced so far. The gene content and order, as well as the nucleotide composition, conform with the well-known features of hexapods’ mitochon...
Article
Full-text available
The complete mitochondrial genome of the machilid Trigoniophthalmus alternatus (Silvestri 1904) is herein described and applied to phylogenetic analyses, inclusive of the most early-divergent lineages of hexapods. Both gene content and order generally conform with the organization of the arthropods’ mitochondrial genome. One gene translocation invo...
Article
In temperate ecosystems, seasonality influences animal behaviour. Food availability, weather, photoperiod and endogenous factors relevant to the biological cycle of individuals have been shown as major drivers of temporal changes in activity rhythms and group size/structure of herbivorous species. We evaluated how diurnal female foraging activity a...
Article
Evolutionary theory suggests two alternative ways in which competitive interactions could vary in response to different levels of food abundance. Competition theory suggests that aggression should be greater when resource availability is lower, as an evolutionary stable strategy to access food. Alternatively, energy allocated to aggressive interact...
Article
Full-text available
Intrinsic and environmental stressors, such as age and seasonality, may influence social behavior and endocrine levels in gregarious foragers, but little is known about how season and age affect both behavioral and physiological responses. We evaluated seasonal/age variation of aggression and vigilance, and seasonal/age variation of endocrine level...

Article
Lactation exerts heavy energetic and physiological costs to mothers, whilst determining early growth and survival of offspring. To mountain ungulates, access to high-quality forage during nursing and weaning is crucial for reproductive success. We have evaluated the effects of pasture quality on suckling behaviour and winter survival of Apennine ch...
Article
Full-text available
Coevolved species should avoid competition through resource partitioning, but human-induced alteration of plant/animal communities may facilitate the onset of competitive interactions. In herbivores, access to high-quality forage in the warm months, that is, during nursing and weaning, influences growth and survival of offspring. In turn, resource...
Article
Full-text available
In mountain ungulates, antipredator behaviour is one of the main constraints on foraging behaviour and habitat selection, especially when newborn, vulnerable offspring are present. Golden eagles have been known to prey on ungulates successfully, but predation may be relatively rare on chamois. Here, we report an unsuccessful predation attempt by a...
Conference Paper
Full-text available
Information is scarce on mechanisms of interspecific competition between wild ungulates. In Abruzzo, Lazio and Molise National Park (ALMNP, Apennine, Italy), we analysed the effects of ecological overlap between red deer Cervus elaphus and Apennine chamois Rupicapra pyrenaica ornata (“vulnerable”, IUCN) on both the quality of grassland and the fora...

The Adélie penguin, owing to the high energy of its non-flight existence, is highly sensitive to ecosystem changes and is considered as an important bio-indicator of ongoing changes in the Southern Ocean, leading to the importance of monitoring and understanding this species as a climate change sentinel. As habitat quality is likely to induce effects on physiology and behavior, PenguinEra proposes to integrate the population monitoring programs of this species with the measurement of a series of genetic and physiological parameters with the aim to:(i) identify a series of proxy of penguin’s health as is possible using non-destructive tissue sampling (feathers, blood); ii) integrate proxies with the bio-ecological responses and the genetic parameters, to establish a baseline against which signals as a consequence of ecosystem change can be detected.
