Bats are an ecologically and taxonomically diverse group accounting for roughly a fifth of mammalian diversity worldwide. Many of the threats bats face (e.g., habitat loss, bushmeat hunting, and climate change) reflect the conservation challenges of our era. However, compared to other mammals and birds, we know significantly less about the populati...

Determining the processes responsible for phenotypic variation is one of the central tasks of evolutionary biology. While the importance of acoustic traits for foraging and communication in echolocating mammals suggests adaptation, the seldom-tested null hypothesis to explain trait divergence is genetic drift. Here we derive FST values from multi-l...

Acoustic signalling is the most important form of communication in anuran amphibians. Here we recorded and analysed the calls of 18 male Guenther’s frogs (Hylarana guentheri) from the wild during the breeding season. The advertisement calls of H. guentheri were composed of from a single note to five notes, with three-note calls the most recorded. A...

Illicit crop cultivation often occurs in forested areas and contributes to deforestation when it results in the clearing of woodland. Moreover, illicit crop cultivation frequently takes place in biodiversity hotspots hosting a large number of species with a limited habitat, some of which are pro- tected areas. It tends to occur close to the agricul...

Male-biased dispersal and female philopatry are common traits among social mammals, often leading to elevated relatedness within social groups. However, exceptions do occur, with documented cases of female-biased dispersal, dispersal by both sexes, and philopatry of both sexes. In this study, we examined levels of dispersal and relatedness based on...

Phylogeographic reconstructions of co-distributed taxa can help reveal the interplay between abiotic factors, such as altitude and climate, and species-specific attributes, in shaping patterns of population genetic structure. Recent studies also demonstrate the value of both range-wide sampling and species distribution modeling (SDM) in comparative...
Conference Paper
Forest microbats that typically fly in the clutter of the understorey or canopy can be difficult to survey using standard techniques. Capture rates tend to be low for such narrow-space foraging bats because they make infrequent use of flyways such as trails where traps and nets would normally be set. Acoustic monitoring is also of limited use with...

Population genetic structure has important consequences in evolutionary processes and conservation genetics in animals. Fine-scale population genetic structure depends on the pattern of landscape, the permanent movement of individuals, and the dispersal of their genes during temporary mating events. The lesser flat-headed bat (Tylonycteris pachypus...

Autopsies carried out on 26 short-nosed fruit bats (Cynopterus sphinx, Pteropodidae, Chiroptera) from Guangdong Province, South China, revealed that the hearts of three individuals were found lying in the right hemithoracic cavity with their base-to-apex axes directed to the right. This is the reverse of what is normally seen in mammals and is simi...

In response to the rapid decline of greater horseshoe bats (Rhinolophus ferrumequinum) in Europe, conservation efforts have previously focused on protecting maternity roosts and hibernacula. Currently, there is little information available on the ecology of this species outside of these 2 main periods. This study investigates patterns of roost use,...

Echolocating bats are able to orientate, navigate and forage without visual cues. To probe the role of vision in bats, we studied the visual opsin genes from the echolocating little brown bat (Myotis lucifugus). Short-wavelength sensitive (SWS1) opsin, middle/long-wavelength sensitive (M/LWS) opsin and rhodopsin cDNA sequences were identified from...

Phylogeographical studies are typically based on haplotype data, occasionally on nuclear markers such as microsatellites, but rarely combine both. This is unfortunate because the use of markers with contrasting modes of inheritance and rates of evolution might provide a more accurate and comprehensive understanding of a species' history. Here we pr...

To develop and test the Autobat acoustic lure in a variety of habitats and with a range of bat species to assess how its effectiveness is influenced by stimulus characteristics (e.g. call type, duty cycle, amplitude), trapping environment and seasonal factors. Enhancing effectiveness for open-space bats and for a greater variety of taxa. Project description The aim of this project is to explore various ways in which the effectiveness of an acoustic lure for bats can be enhanced. The Sussex Autobat acoustic lure was first developed and tested more than twelve years ago (Hill & Greenaway, 2005), and has led to more than 20 publications in which it has been used either to survey bats (e.g. Goiti et al., 2007; Michaelsen et al., 2011; Kirkpatrick at al., 2017), or as an aid to catching bats for radio-tracking and other sampling (e.g. Murphy et al., 2012; Fukui, et al., 2012; Vesterinen et al., 2013), or it has been tested in its own right (e.g. Hill et al., 2014a, b; Lintott et al., 2014). Although we know from accumulated experience that the effectiveness of the Autobat is influenced by how it is used, there has been little systematic work on optimising its effectiveness. The main reason for this is that, in most cases when researchers or surveyors use the lure, their main objective is to catch the target bats as quickly and efficiently as possible. To simultaneously run systematic tests to assess how various settings and conditions influence the effectiveness of the lure would be time-consuming and would probably reduce the capture rate. In this project we hope to approach this problem by incorporating an element of systematic testing into a variety of studies that require the capture of bats, and gradually incorporate the results into a model of how best to optimise the Autobat. A key area to explore is the relative effectiveness of different stimuli. The Autobat is an ultrasound synthesiser that we use to produce simulations of bat social calls. While some calls are effective for a wide range of species, there is evidence that bats respond most readily to stimuli based on their own species’ social calls (Schöner et al., 2010; Murphy, 2012). However, each species produces a variety of different social calls, and some are much more effective for attracting bats than others, so using the right calls is essential. We tend to use social calls recorded from free-flying bats as models for the stimuli, rather than calls recorded inside a roost, or distress calls recorded from captured bats. Other factors that are likely to influence capture rates, but whose impact is poorly understood include the temporal patterning of broadcasting the stimuli, the loudness of the signal, the type, the number and location of speakers in relation to the trap or net and the location of the trap or net in relation to clutter and potential flyways. Optimum conditions will vary according to the objectives of the work. For example, whether the lure is being used to attract a single target species, or to make an assessment of bat diversity at a site. It will also vary with habitat and the assemblage of bats that use it. Consequently, our aim is to extract general principles that can aid optimisation in a variety of situations, and for a variety of species and communities.
