Evolutionary Morphology of the Rabbit Skull
Evolutionary morphology of the rabbit skull Brian Kraatz1 and Emma Sherratt2 1 Department of Anatomy, Western University of Health Sciences, United States 2 Department of Evolution, Ecology and Genetics, Research School of Biology, The Australian National University, Canberra, ACT, Australia ABSTRACT The skull of leporids (rabbits and hares) is highly transformed, typified by pronounced arching of the dorsal skull and ventral flexion of the facial region (i.e., facial tilt). Previous studies show that locomotor behavior influences aspects of cranial shape in leporids, and here we use an extensive 3D geometric morphometrics dataset to further explore what influences leporid cranial diversity. Facial tilt angle, a trait that strongly correlates with locomotor mode, significantly predicts the cranial shape variation captured by the primary axis of cranial shape space, and describes a small proportion (13.2%) of overall cranial shape variation in the clade. However, locomotor mode does not correlate with overall cranial shape variation in the clade, because there are two district morphologies of generalist species, and saltators and cursorial species have similar morphologies. Cranial shape changes due to phyletic size change (evolutionary allometry) also describes a small proportion (12.5%) of cranial shape variation in the clade, but this is largely driven by the smallest living leporid, the pygmy rabbit (Brachylagus idahoensis). By integrating phylogenetic history with our geometric morphometric data, we show that the leporid cranium exhibits weak phylogenetic signal and substantial homoplasy. Though these results make it difficult to reconstruct what the `ancestral' leporid skull looked like, the fossil records suggest that dorsal arching and facial tilt could have occurred before the origin of the crown group. -

I have the privilege of forwarding the fi eld guide on mammals of Ladakh which is part of a series of bilingual (English and Ladakhi) fi eld guides developed by WWF-India. It is not just because of my involvement in the conservation issues of the state of Jammu & Kashmir, but I am impressed with the Ladakhi version of the Field Guide. As the Field Guide has been specially produced for the local youth, I hope that the Guide will help in conserving the unique mammal species of Ladakh. I also hope that the Guide will become a companion for every nature lover visiting Ladakh. I commend the efforts of the authors in bringing out this unique publication.

PICA Project Report (Action A2.2 & 2.3)
PICA Project Report (Action A2.2 & 2.3) Investigation of Pallas’s cat activity patterns and temporal interactions with sympatric species Authors: Katarzyna Ruta, Gustaf Samelius, David Barclay, Emma Nygren PICA - “Conservation of the Pallas’s cat through capacity building, research, and global planning” 1. Introduction: 1.1 Activity patterns of wild felids: Activity patterns form a part of species’ adaptation to their environment (Beltran & Delibes, 1994) and are therefore a fundamental aspect of animal behaviour (Nielsen, 1983; Weller & Bennett, 2001). Felids are generally considered to be crepuscular and nocturnal in their activity (Kitchener, 1991), although they are well adapted to function in a wide range of light conditions (Sunquist & Sunquist, 2002). Numerous abiotic pressures and biotic interactions are known to shape the temporal behaviour of (cat-like) carnivores (Marinho et al., 2018), including changes in temperature (Beltran & Delibes, 1994; Podolski et al., 2013), light (Huck et al., 2017; Heurich et al., 2014) and season (Podolski et al., 2013; Manfredi et al., 2011), sex and reproductive status of the animal (Kolbe & Squires, 2007; Schmidt, 1999; Schmidt et al., 2009), predation risk (Caro, 2005; Farías et al., 2012) and human disturbance (Wolf & Ale, 2009; Ale & Brown, 2009). Owing to the dietary constraints of carnivores whose preys have their own well-defined circadian rhythms (Halle, 2000; Zielinski, 2000), the availability and vulnerability of prey is, however, considered as one of the main influences on predator temporal activity (Zielinski, 1988; Lodé, 1995). According to Optimal Foraging Theory, predators are expected to synchronize their daily activity with the activity of their most profitable prey, increasing the probability of encounters while reducing energy expenditure (MacArthur & Pianka, 1966; Monterroso et al., 2013; Emmons, 1987). -

Diversity, extinction, and threat status in Lagomorphs. – Ecography doi: 10.1111/ecog.01063 Supplementary material 1 Appendix 1 2 Paleobiogeographic summaries for all extant lagomorph genera. 3 4 Pikas – Family Ochotonidae 5 The maximum diversity and geographic extent of pikas occurred during the global climate 6 optimum from the late-Oligocene to middle-Miocene (Ge et al. 2012). When species evolve 7 and diversify at higher temperatures, opportunities for speciation and evolution of thermal 8 niches are likely through adaptive radiation in relatively colder and species poor areas 9 (Araújo et al. 2013). Extant Ochotonids may be marginal (ecologically and geographically) 10 but diverse because they occur in topographically complex areas where habitat diversity is 11 greater and landscape units are smaller (Shvarts et al. 1995). Topographical complexity 12 creates new habitat, enlarges environmental gradients, establishes barriers to dispersal, and 13 isolates populations. All these conditions can contribute to adaptation to new environmental 14 conditions and speciation in excess of extinction for terrestrial species (Badgley 2010). 15 16 Hares and rabbits - Family Leporidae 17 Pronolagus, Bunolagus, Romerolagus, Pentalagus and Nesolagus may belong to lineages 18 that were abundant and widespread in the Oligocene and subsequently lost most (if not all) 19 species. Lepus, Sylvilagus, Caprolagus and Oryctolagus represent more recent radiations 20 which lost species unevenly during the late Pleistocene. Living species in these four genera 21 display more generalist diet and habitat preferences, and are better represented in the fossil 22 record. (Lopez-Martinez 2008). -

E-mail: [email protected] (ACR) *Corresponding author Introduction: Lagomorphs (rabbits, hares, and pikas) are widely distributed in every continent of the world, except Antarctica. They include 91 species: 31 rabbits of the genera Brachylagus , Bunolagus , Caprolagus , Nesolagus , Pentalagus , Poelagus , Prolagus , Pronolagus , Romerolagus, and Sylvilagus ; 32 hares of the genus Lepus and 28 pikas of the genus Ochotona . According to the International Union for Conservation of Nature (IUCN 2014), the list of threatened species of lagomorphs includes one extinct, three critically endangered, ten endangered, %ve near threatened, %ve vulnerable, 61 of least concern, and six with de%cient data. Although a rich diversity of lagomorphs and endemic species exists, some of the wild populations have been declining at an accelerated rate, product of human activities and climate change. -
Factors Influencing Snowshoe Hare (Lepus Americanus) in Michigan
Factors influencing snowshoe hare (Lepus americanus) in Michigan By David Michael Burt A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Fisheries and Wildlife – Master of Science 2014 ABSTRACT Factors influencing snowshoe hare (Lepus americanus) in Michigan By David Michael Burt The goal of my thesis was to identify the climatic and vegetation factors that influence snowshoe hare occupancy in Michigan. My objectives were to: 1) quantify snowshoe hare occupancy as related to climate change and 2) quantify the relationships between patch-level snowshoe hare occupancy and land cover change over time, current land cover, habitat structure, and mesocarnivore presence. In Chapter 1, I determined the most efficient transect configurations for winter track surveys and found that transects 150m in length with 100 or 75m spacing, or 125m in length with 75m spacing provided reliable estimates of hare occupancy. In Chapter 2, I researched climatic variables that are potentially linked to snowshoe hare population performance and assessed whether those factors affected the localized extinction of snowshoe hares. I found that localized extinction was influenced by maximum temperature from May 15 – January 19; as temperature increased the likelihood of localized extinction increased. I also found that the total number of days with measurable snow on the ground affected localized extinction; as number of days with snow on the ground decreased the likelihood of localized extinction increased. In Chapter 3, I evaluated whether land cover change over time, current land cover, and habitat factors affected snowshoe hare occupancy and habitat use. I found that land cover change over time did not affect hare occupancy. -
Appendix Lagomorph Species: Geographical Distribution and Conservation Status
Appendix Lagomorph Species: Geographical Distribution and Conservation Status PAULO C. ALVES1* AND KLAUS HACKLÄNDER2 Lagomorph taxonomy is traditionally controversy, and as a consequence the number of species varies according to different publications. Although this can be due to the conservative characteristic of some morphological and genetic traits, like general shape and number of chromosomes, the scarce knowledge on several species is probably the main reason for this controversy. Also, some species have been discovered only recently, and from others we miss any information since they have been first described (mainly in pikas). We struggled with this difficulty during the work on this book, and decide to include a list of lagomorph species (Table 1). As a reference, we used the recent list published by Hoffmann and Smith (2005) in the “Mammals of the world” (Wilson and Reeder, 2005). However, to make an updated list, we include some significant published data (Friedmann and Daly 2004) and the contribu- tions and comments of some lagomorph specialist, namely Andrew Smith, John Litvaitis, Terrence Robinson, Andrew Smith, Franz Suchentrunk, and from the Mexican lagomorph association, AMCELA. We also include sum- mary information about the geographical range of all species and the current IUCN conservation status. Inevitably, this list still contains some incorrect information. However, a permanently updated lagomorph list will be pro- vided via the World Lagomorph Society (www.worldlagomorphsociety.org). 1 CIBIO, Centro de Investigaça˜o em Biodiversidade e Recursos Genéticos and Faculdade de Ciˆencias, Universidade do Porto, Campus Agrário de Vaira˜o 4485-661 – Vaira˜o, Portugal 2 Institute of Wildlife Biology and Game Management, University of Natural Resources and Applied Life Sciences, Gregor-Mendel-Str. -

Pygmy Hog and Hispid Hare
103 Pygmy Hog and Hispid Hare The re-discovery of the pygmy hog Sus salvanius in some numbers in the Himalayan foothills of Assam this year was an exciting event in which the members of the FPS Indian tour participated: they obtained what may be the first photographs ever taken of this diminutive rare animal. When in April fourteen were captured as well as one hispid hare (probably much more endangered), and held on tea estates in Assam the FPS sent an investigator, Mr Jeremy Mallinson, to report. The following account is largely based on his report. In March this year members of the FPS tour in India saw and photographed a tiny wild pig they thought must be a pygmy hog. This was in the Manas Sanctuary, in the Himalayan foothills on the Bhutan border. Their leader, Dr David Jenkins, however, being a good scientist said firmly, 'feared extinct - identification to be confirmed'. But unknown to the FPS party pygmy hogs were being seen — and caught and eaten — in some numbers some 70 or 80 miles to the east, thanks to an extensive fire which swept through fifty square miles of the tall grass areas known as thatchlands, between the Rajagarh forest reserve and the Attareekhat tea estates in Mangaldai, owned by Williamson Magor & Co. The fire drove the pygmy hogs out of their natural cover. For some time there had been rumours of pygmy hogs, and in January this year Mr Richard Magor, Director of the Attareekhat Tea Co. and a founder of the Assam Valley Wildlife Scheme, had asked his staff to try to secure some.
