Wildlife Ecology Research

About


The  Wildlife Ecology research theme forms part of our Biological Sciences research team. Our work falls into three main areas: 

  • Tropical ecosystem challenges
  • Upland landscape ecology
  • Biodiversity conservation

We investigate species, population and community relationships with anthropogenic drivers of change to biodiversity, ecosystems, and the provision of co-beneficial goods and services. Our outcomes inform conservation and restoration options, processes and policies that remediate impacts of anthropic activities. We undertake and support field research in the Azores, Costa Rica, Honduras, Indonesia, Ireland, Mexico, Pakistan, the Philippines, South Africa and the UK.  


Research Areas

Tropical ecosystem challenges 

Our work on the challenges of conserving and restoring tropical ecosystems, both terrestrial and marine, includes understanding species and community interactions along gradients of environmental quality or degradation, and modelling these to provide specific ecological benchmarks for effective conservation and restoration management of species and systems. Our work endeavours to support the co-benefits of biodiversity, ecosystem functionality, goods and services, and local communities. Current research projects include relating spatial patterns in threatened forest birds of the Negros and Panay Endemic Bird Area (the Philippines) to gradients of habitat degradation and recovery, ecological consequences of long-spined sea urchin (Diadema antillarum) dieback on degraded Caribbean coral reefs (Honduras), and forest restoration that supports the conservation of the globally threatened sun bear (Helarctos malayanus; southeast Asia).

Upland landscape ecology 

We collaborate with government and public bodies on research in upland landscapes, both in Wales and internationally, that contributes to landscape management decision-making. Our projects are identifying landscape attributes that affect breeding birds of the uplands, for example, hen harrier (Circus cyaneus) and red grouse (Lagopus lagopus), suitability metrics for key birds in the Brecon Beacons, including the locally extirpated black grouse (Lyrurus tetrix), consequences of commercial afforestation on ecological communities and species abundances in upland habitats, and spatio-temporal patterns in bird communities in remote areas of Pakistan.

Biodiversity conservation 

Our research on biodiversity conservation focuses on understanding the interactions between species and their anthropic stressors to inform effective species conservation decision-making and management. Project areas include hen harrier genetics and movement ecology (Europe), human-nonhuman primate interactions, including the impacts of ecotourism on non-human primates (Costa Rica), climate change and breeding woodland birds, particularly pied flycatcher (Ficedula hypoleuca; UK), Asiatic black bear (Ursus thibetanus) habitat use and human interactions (southeast Asia), population assessment of tarictic hornbill (Penelopides panini; the Philippines), and invasive rodents and nesting seabirds (Gough Island).

Overview:

An estimated 63% of Southeast Asian forests are classed as disturbed and secondary as a result of human activity. Many of these forests remain important for biodiversity conservation and ecosystem services so there is much interest in their capacity for restoration. 

The role of larger animals as seed dispersers in natural regeneration is well attested, since they are often the only agent by which some trees can disperse effectively. This is especially important for late successional, shade-tolerant species that might otherwise be excluded from disturbed sites. However, many larger animals are sensitive to habitat degradation so may be lost from the very areas that require them. 

We investigated the persistence of a suite of large mammals that are known seed-dispersers and also threatened species, in a degraded site in lowland south-central Sumatra. We used camera traps and field observations to relate their distributions to prevailing vegetation conditions. 

Key findings:

  • Although most species were more frequently detected in the more intact, least disturbed forested areas, most were able to at least occupy habitats with high levels of disturbance. 

Outcomes and impact:

  • Severe habitat degradation does not necessarily lead to the immediate loss of large-bodied seed dispersers, so ensuring adequate protection for these species from external threats, such as hunting, must be built into management plans for restoration concessions.

Malayan Sun Bear Wildlife Ecology Research GettyImages-1089521014.jpg

Overview:

Malayan sun bear (Helarctos malayanus) is a forest-dependent species globally threatened by loss of suitable habitat and hunting. Understanding how sun bears utilise habitat in more degraded landscapes is increasingly important for the effective conservation of the species. 

We conducted surveys of bear sign alongside habitat classification to indicate how landscape and plot attributes affect sun bear habitat use along a gradient of logging disturbance in a lowland forest site of Sumatra. This research informs forest restoration strategies that benefit the conservation management of the species. 

Key findings:

  • Sun bear habitat use appeared to be non-random and was significantly associated with gradients of increasing habitat intactness, from non-forest habitat to least disturbed forest. 
  • Two environmental gradients explained the probability of bears utilising a given habitat, which increased with tree biomass and decreased with understorey cover. 
  • At the plot level, tree family and species compositions were significantly different between areas where bears were recorded and where they were absent.
  • For example, the abundance and use by bears of Olacaceae tree stems was higher in plots with bear sign. 
Outcomes and impact:

  • Incorporating forest restoration strategies that enhance or increase more intact forest and the availability of key tree resources will benefit the conservation of sun bears and encourage natural forest regeneration in these degraded landscapes. 
  • This emphasises the conservation value of degraded forest habitats for this species, while ensuring bear movement and connectivity within modified landscape matrices.

Male mantled howler

Overview:

While howler monkeys are the most ecologically flexible of the atelines, they must still respond to issues arising from anthropogenic modifications, such as fragmentation or dietary changes. Mantled howlers living in a highly modified landscape (commensal group) at the Curú Wildlife Refuge in Costa Rica was compared to howlers with limited human influence (control group). 

Key findings:

  • The commensal group had a more frugivorous diet than the control group, due to crop-foraging of mango fruits.
  • The commensal group maintained a larger home range than the control group, at 39 and 10 ha, respectively. 
  • The commensal group had increased travel and feeding times, as well as reduced proximity to conspecifics.
  • Aggressive or affiliative social behaviours did not change across groups.

Outcomes and impact:

  • Increased home range, shift in diet, increased travel and foraging time and reduced group cohesion demonstrated by the species represent responses to the varied utility of available landscapes and the more widely dispersed resources in their range. 
  • This contributes to our ecological understanding of howler monkeys, one of the most successful of Neotropical primates in modified landscapes.

Wallaby - Ecology Research Dr Anthony Caravaggi

Overview:

Investigating the range and population dynamics of introduced species provides insight into species behaviour, habitat preferences, and their potential for becoming established populations. 

Using records from Local Environmental Records Centres (LERCs), the National Biodiversity Network (NBN), and popular media from 2008 to 2018, this research describes the current population status of red‐necked wallaby (Notamacropus rufogriseus). All records were mapped and compared to a historical distribution map (1940–2007), derived from published data. 

Key findings:

  • Of 95 confirmed wallaby sightings from the study period, 64 came from media sources, 18 from LERCs, seven from the NBN, and six from the published literature. 
  • The greatest density of wallaby sightings was in southern England, with the Chiltern Hills Area of Outstanding Natural Beauty a particular hotspot.
  • More sightings were recorded in August than in any other month. 

Outcomes and impact:

  • Much of the species’ ecology and responses to British biota and anthropogenic pressures are unknown, and therefore, further research is warranted.
  • The contemporary methods used here are widely applicable to other non‐native species, particularly those that the public are more likely to report and could be an important supplement to existing studies of conservation and management relevance.

Outline:

The Bornean banteng (Bos javanicus lowi) is an endangered subspecies that often inhabits logged forest; however very little is known about the effects of logging on their ecology, despite the differing effects this has on other ungulate species. A body condition scoring system was created for the Bornean banteng using camera trap photographs from forests in Sabah, Malaysia, with various past and present management combinations to establish if banteng nutrition suffered as a result of forest disturbance.

Key findings:

  • Banteng within forests that had a recent history of reduced-impact logging (RIL) had higher body condition scores than banteng within conventionally logged forest. 
  • Conversely, when past logging was conducted using a conventional technique and the period of forest regeneration was relatively long; the banteng had higher body condition scores.

Outcomes and impact:

  • The body condition scoring system is appropriate for monitoring long-term nutrition of the Bornean banteng and for evaluating the extent of the impact caused by present-day RIL methods
  • The findings demonstrate the complex effects of logging approaches and history on banteng body condition, which is likely due to differences in regeneration between forests that have been previously logged using differing methods.
