This EU-funded project, led by Dr Stefano Vaglio & Dr Chris Young, aims to create a higher-level training programme for zoo staff including three postgraduate-level modules in international zoo management to upskill zoo professionals.

The modules, which are now in development, are in international zoo welfare and management, international management of zoo-based conservation, and ethical and legal issues with international zoo management. These will be delivered by the three partner higher education institutions; University of Wolverhampton, University of Bologna (Italy), and University of Limoges (France). The other three project partners are Twycross Zoo, Budapest Zoo (Hungary), and Parco Natura Viva (Italy). Their expertise will be complemented with the input from associate partners, which include Dudley Zoo & Castle, Ecole Nature Recherche (France), Fondazione ARCA (Italy), as well as the British and Irish Association of Zoos and Aquaria and the European Association of Zoos and Aquaria.

Through a mix of partner-focused workshops, a wider multiplier event and a summer school, the consortium will develop and test a suite of training materials that can be used either independently within the context of each training module or as part of a coherent whole.

Ultimately the aspiration is to develop the modules into a formal international postgraduate qualification led by the University of Wolverhampton.

Most primate species are currently classified as endangered or critically endangered. Many of them are preserved in modern zoos that serve as ambassadors of endangered species, breeders of populations acting as buffers against extinction, and educators of the general public. The gentle lemur (Hapalemur alaotrensis) and the red-ruffed lemur (Varecia variegata rubra) are two of the 25 most endangered primates in the world, and currently showing a low success rate in captive breeding. This EU-funded project, led by Dr Stefano Vaglio in collaboration with Dr Sara Fontani and Ms Emily Elwell (PhD research student), aims to identify and reproduce the female lemur’s fertile chemical signature and then test its effects on mating success and welfare of captive troops. We conducted a preliminary study on the effects of essential oils (Vaglio et al. 2021). However, ultimately we aim to design a new scent enrichment which triggers mating behaviour in zoo-housed lemurs, by combining methods that integrate cutting-edge semiochemistry with established behavioural observations and faecal endocrinology (Department of Veterinary Sciences, Bologna) and innovative faecal gut microbiota analysis (Department of Biology, Florence). This work will provide findings which should also entail quantifiable impact, such as best practices adopted by target zoos (Jersey Zoo, Wild Place Project - Bristol, Birmingham Wildlife Conservation Park, Dudley Zoo & Castle, Twycross Zoo) and extended to other EAZA institutions through amendments in husbandry and management policies released by International Studbook Keepers & Ex situ Programme Coordinators for the target species at European level.

Within its native range in southern Africa, the African clawed frog, Xenopus laevis, is the most widely distributed of all amphibian species spanning multiple climatic regimes where they display asymmetrical plastic responses to changing environments. Additionally accidental or deliberate release of individuals from laboratories or breeding facilities resulted in the invasion of this amphibian on four other continents. Dr Natasha Kruger was awarded the Dr Marie Wasdell and Malkito Kaur Gangar Fellowship for the Sciences to investigate the developmental plasticity of X. laevis in its native and invasive ranges, as well as in captive populations in response to changing temperatures. In collaboration with the Technical University of Braunschweig (TUB), in Germany, they will evaluate whether adaptation to homogenous environments such as captivity reduces developmental plasticity over time using an approach comparing wild-caught and laboratory X. laevis. They will examine a suite of developmental traits in response to acclimation to temperatures across their entire thermal range. This project aims to build on the previous work of Dr Natasha Kruger investigating the phenotypic plasticity of invasive X. laevis in its native and invasive range (Kruger et al. 2022). In addition to creating new collaborative networks with TUB, the project will continue to develop links with the University of Angers (France), North-West University and Stellenbosch University (South Africa) and the European Xenopus Resource Centre (UK).

The elapid genus Toxicocalamus is endemic to the island of New Guinea, and a number of its satellite archipelagos, but although the genus has been known to science since 1896 it has been the source of considerable taxonomic confusion. Only 520 voucher specimens are held by thirty museums worldwide and many of these could not with confidence be allocated to any known taxon. The genus is primarily distributed across areas of New Guinea that originated as Pacific terranes that collided with the Australian craton and they are believed to be close to the phylogenetic origin of the hydrophiine snakes. Members of the genus are diurnal yet secretive, oviparous and vermophagous.  Their natural history and biogeography is only partially documented. 

The project has so far led to the description of two new species within this genus, and papers currently in preparation will resurrect three species from synonymy, elevate one taxon from subspecific to specific status, and lead to the description of at least three new species. 

Most species of Toxicocalamus are localised in their distributions, being confined to single islands or mountain ranges, and are therefore potentially threatened by ongoing copper or gold mining, deforestation, and oil exploration.

The rapid expansion of human populations has resulted in dramatic changes of the global and local ecosystems, transforming primate habitats and increasingly placing non-human primates in proximity of humans. This proximity often leads to competition over resources and space between humans and non-human primates which can have detrimental effect on both people and animals. This project led by Dr Stefano Kaburu in collaboration with the McCowan lab at UC Davis aims to investigate conflict dynamics between people and macaques in Asian countries, especially India and Malaysia with the ultimate goal to generate a peaceful coexistence between humans and monkeys. This project, funded by the National Science Foundation, is currently examining the factors driving the conflict between people and macaques and the consequences of the conflict for them. This project, to date has shown that several macaque attributes, in particular sex and social group position, predict macaques’ interactions with people (Balasubramaniam et al., 2020) and that interactions between humans and macaques alter macaque social behaviour which may have long-term consequences for macaque welfare (Kaburu et al., 2019a; 2019b). Moving forward, Dr Kaburu aims to examine: (a) the physiological consequences (energetic balance, immune regulation, stress response) for macaques who live alongside people; and (b) the risks of disease transmission between people and monkeys. Collectively, this work will provide crucial information to both understand what are the costs animals and people have to face due to the conflict and implement intervention strategies aimed at reducing this conflict.

The use of automated passive acoustic monitoring (PAM) for surveying wildlife has expanded the toolkit for conservationists and ecologists interested in monitoring biodiversity. PAM is a remote sensing technique whereby researchers place audio recorders in the habitat of study subjects to passively record acoustic signals in the form of vocalizations, or other audible signs that act as cues to the presence of a target species. These cues confirm the presence of the target species, and can be used to estimate a species’ abundance, distribution, and population trends over time.

This project, led by Dr Colin Dubreuil in collaboration with researchers at Manchester Metropolitan University, aims to investigate the utility of passive acoustic monitoring for neotropical primates in the Peruvian Amazon. This RIF4 funded project is currently focussed on exploring the utility of passive acoustic monitoring for nine species of primates across two biomes characterized by varying levels of anthropogenic disturbance. Moving forward, Dr Dubreuil aims to a) explore the utility of PAM for monitoring individual social groups, based on structural differences in their territorial long calls, and b) explore the linkage between different ecological variables, including levels of anthropogenic disturbance, on environmental soundscapes.

The primary investigator, Mark O’Shea, has established a database listing the snakes present on over 2,525 islands worldwide, from the largest tropical island, New Guinea, down to islets of less than one hectare.  

The project sets out to determine the factor affecting island ophidiofaunas, including island area, island elevation, island origin,closeness to neighbouring islands, closeness to the mainland, and the effects of human interactions, from changes in land use to the introduction of invasive species. 

This project has already initiated a collaboration with a senior herpetological biogeographer at the Universidade de São Paulo, Brazil, and will result in a chapter in a forthcoming volume on snake island biogeography to be published by Oxford University Press in January 2024.
