Article
Full-text available
Conservation action is usually triggered by detecting trends in species’ population size, geographical range, or occupancy (proportion of sites occupied). Robust estimates of these metrics are often required by policy makers and practitioners, yet many species lack dedicated monitoring schemes. An alternative source of data for trend estimation is...
Article
Full-text available
Sex identification of adult cetaceans is an important ecological parameter that should be incorporated into studies such as population dynamics and animal behavior. In Cuvier’s beaked whale (Ziphius cavirostris), sex determination may be achieved through genetics, observation of genitals, the presence/absence of erupted teeth, and calf association....
Article
Full-text available
International shipping, although considered a safe and environment-friendly form of transportation, has many direct and indirect impacts on cetaceans in many ways, particularly in the Mediterranean Sea, one of the world's busiest waterways. An AIS receiver located at 44.30 °N and 8.45 °E, operating between 3 May 2013 and 31 October 2014, provided a...
Article
Full-text available
Acoustic deterrent devices (ADDs) are used in attempts to mitigate pinniped depredation on aquaculture sites through the emission of loud and pervasive noise. This study quantified spatio-temporal changes in underwater ADD noise detections along western Scotland over 11 years. Acoustic point data (‘listening events’) collected during cetacean line-...
Article
Full-text available
The Cuvier's beaked whale (Ziphius cavirostris) is one of the least known cetacean species worldwide. The decreasing population trend and associated threats has led to the IUCN categorising the Mediterranean subpopulation as Vulnerable on the Red List of Threatened Species. This study aimed to investigate for the first time the ecotoxicological sta...
Article
The exposure of wildlife to waste plastic is widely recognised as an issue for aquatic ecosystems but very little is known about terrestrial systems. Here, we addressed the hypothesis that UK small mammals are ingesting plastics by examining faecal samples for the presence of plastic using micro Fourier Transform infrared microscopy. Plastic polyme...

Article
Recent research on Cuvier’s beaked whales (Ziphius cavirostris) from the Mediterranean has demonstrated that sexes can be visibly distinguished in photos using sex-linked patterns of scarring density and pigmentation, even at age classes which are notoriously difficult to differentiate. Being able to apply this research to other populations would a...

Article
Full-text available
: Artificial light at night (ALAN) can have negative consequences for a wide range of taxa. However, the effects on nocturnal mammals other than bats are poorly understood. A citizen science camera trapping experiment was therefore used to assess the effect of ALAN on the activity of European hedgehogs (Erinaceus europaeus) at supplementary feeding...
Article
Full-text available
Road vehicle collisions are likely to be an important contributory factor in the decline of the European hedgehog ( Erinaceus europaeus) in Britain. Here, a collaborative roadkill dataset collected from multiple projects across Britain was used to assess when, where and why hedgehog roadkill are more likely to occur. Seasonal trends were assessed u...
Technical Report
Full-text available
The State of Nature report 2019 presents an overview of how wildlife is faring in the UK and its Overseas Territories and Crown Dependencies. Additionally, it assesses the pressures that are acting on nature, and the responses being made, collectively, to counter these pressures.

Management regulations for whale-watching (ww) are fundamental in the Pelagos Sanctuary and ACCOBAMS area. The aim of this work is to test the use of 3 indicators describing the ww vessel “behaviour”: the average vessel speed during the approach, the average distance of significant speed decrease and the time spent with the animals. For the very fi...
Conference Paper
Full-text available
The International Sanctuary for the Protection of Mediterranean Marine Mammals was established in order to improve conservation measures where cetaceans are abundant and highly impacted by human pressures. Shipping is one of the main human activity in the Sanctuary with many impacts on the ecosystem but still, it is not well known. This study prese...
Conference Paper
Full-text available
Sex determination is essential in studies relating to behaviour, population dynamics and demographics. In Cuvier’s beaked whales (Ziphiuscavirostris) there are known to be differences in scarring which are both sexand age dependent (Rosso et al. 2011). Analyzing photos of adult Cuvier’s beaked whales, the aim of this study was to quantitatively add...
