Introduction
I'm a Lecturer in Conservation Biology and ecologist at the The University of South Wales, and freelance ecological statistician under AC Ecological Statistics (ACES). My work is broadly focussed on conducting research that increases our understanding of species ecologies and informs conservation and management processes. I have broad interests in ecology (e.g. urban, community, movement, spatial, invasive), particularly of rare and threatened species.

Invasive species are the main threat to island biodiversity; seabirds are particularly vulnerable and are one of the most threatened groups of birds. Gough Island, a UNESCO World Heritage Site in the South Atlantic Ocean, is an Important Bird and Biodiversity Area, and one of the most important seabird colonies globally. Invasive House Mice Mus mus...

Roads have considerable ecological effects that threaten the survival of some species, including many terrestrial carnivores. The western polecat is a small-medium sized mustelid native to Asia and Europe, including Britain where its historical stronghold is in Wales. Polecats are frequently killed on roads and road casualties represent the most co...

Tarsus length, minimum or maximum, is a commonly recorded metric used in a variety of ornithological studies. The nature of the relationships between minimum and maximum tarsus lengths and the accuracy with which one can be derived from the other is unknown. We explored the strength of the relationships between tarsus measurements across six specie...

The Newport Wetlands National Nature Reserve holds Wales’ only breeding colony of Pied Avocets Recurvirostra avosetta. However, colony productivity is consistently low due to predation of eggs and chicks by both avian and mammalian predators. Here we describe predator activity, mobbing activity and predation events during the 2019 breeding season u...

The state of Paraiba is one of those with the most degraded Caatinga that presents the large gap of knowledge concerning the mammal fauna. Mammals are among the taxa most affected by this. In this sense, we evaluated non-volant mammals' richness and composition between March 2013 and February 2020 in a Caatinga fragment (121 ha). We used active sea...

Academic conferences play an important role in the scientific community by providing an opportunity for researchers to discuss their work and to network. However, drawbacks of traditional face‐to‐face (F2F) conferences, such as the ostensible exclusion of non‐scientists, the substantial environmental footprint, and the large costs in terms of both...

Carnivores typically exhibit cryptic behavior, which makes it difficult to study the ecology of species in this group. Camera trap bycatch can be a valuable source of important opportunistic records. In this short communication, we present rare records of carnivores in southern Brazil. The first record was of a tayra (Mustelidae) with anomalous col...

Anthropogenic land-use change, such as commercial afforestation, is a significant driver of shifts in ecological communities and species abundance. In this study, the consequences of afforestation of upland habitats for two distinct animal groups, birds and small mammals, were examined by comparing open moorland, early pre-thicket conifer forests (...

en • The number of reported collisions (i.e. strikes) between aircraft and wildlife is increasing globally, with consequences for personnel and passenger safety as well as for industry economics. These are important considerations for airport operators that are obliged to mitigate wildlife hazards at airfields. Incidents involving mammals account...

Investigating the range and population dynamics of introduced species provides insight into species behavior, habitat preferences, and potential of becoming established. Here, we show the current population status of the red‐necked wallaby (Notamacropus rufogriseus) in Britain based on records from an eleven‐year period (2008–2018). Records were ob...

Hen Harrier Circus cyaneus and Short-eared Owl Asio flammeus are open-country birds of prey with overlapping distributions. Although both species face similar conservation threats across their ranges, work to date has largely been undertaken at a national scale with few attempts to collate and assess factors relevant to their conservation at an int...

Camera traps (CTs) are an increasingly popular method of studying animal behavior. However, the impact of cameras on detected individuals—such as from mechanical noise, odor, and emitted light—has received relatively little attention. These impacts are particularly important in behavioral studies in conservation that seek to ascribe changes in beha...

Myxomatosis is a highly contagious, frequently fatal viral disease affecting both wild and domesticated European rabbits across many areas of the world.

Rewilding is emerging as a major issue in conservation. However, there are currently a dozen definitions of rewilding that include Pleistocene rewilding, island rewilding, trophic rewilding, functional rewilding and passive rewilding, and these remain fuzzy, lack clarity and, hence, hinder scientific discourse. Based on current definitions, it is u...

The formulation and provision of appropriate diets for zoo animals is important in ensuring the continued health of populations. Inappropriate diets can lead to a number of nutritional deficiencies and increase the risk of disease and obesity. Ruffed lemurs (Varecia spp.) are the most intensely frugivorous of extant lemur species. Captive animals a...

An understanding of animal behaviour is important if conservation initiatives are to be effective. However, quantifying the behaviour of wild animals presents significant challenges. Remote-sensing camera traps are becoming increasingly popular survey instruments that have been used to non-invasively study a variety of animal behaviours, yielding k...

remBoot is an implementation of the Random Encounter Model (REM) developed by Rowcliffe et al. (2008). The REM is based on Brownian motion and allows the estimation of animal densities for a given survey area. The REM is particularly useful in that species do not need to be marked or exhibit individual markings for estimates to be calculated. This...

Camera traps are used to estimate densities or abundances using capture-recap- ture and, more recently, random encounter models (REMs). We deploy REMs to describe an invasive-native species replacement process, and to demonstrate their wider application beyond abundance estimation. The Irish hare Lepus timidus hibernicus is a high priority endemic...

The European hare (Lepus europaeus) has declined throughout its native range but invaded numerous regions where it has negatively impacted native wildlife. In southern Sweden, it replaces the native mountain hare (L. timidus) through competition and hybridisation. We investigated temporal change in the invasive range of the European hare in Ireland...
