Background The two forms of white rhinoceros; northern and southern, have had contrasting conservation histories. Northern form, once fairly numerous is now critically endangered, while the southern form has recovered from a few individuals to population thousand. Since their last taxonomic assessment over three decades ago, new material analytical techniques become available, necessitating review available information re-assessment taxonomy. Results Dental morphology cranial anatomy clearly...
The black rhinoceros is again on the verge of extinction due to unsustainable poaching in its native range. Despite a wide historic distribution, was traditionally thought as depauperate genetic variation, and with very little known about evolutionary history. This knowledge gap has hampered conservation efforts because hunting dramatically reduced species' once continuous leaving five surviving gene pools unknown affinity. Here we examined range-wide structure modern populations using...
Abstract Phylogenetic relationships among 36 Recent and 42 extinct species of the Caninae (Canidae) were analysed, based on 360 morphological, developmental, ecological, behavioural cytogenetic characters 24 mitochondrial nuclear markers. Primary phylogenetic analyses accompanied by experimental various combinations data partitions taxon samples. Leptocyon was recovered as a paraphyletic stem lineage Caninae; monophyly/paraphyly fox‐like canids (Vulpini) remains uncertain; Urocyon Metalopex...
Phylogenetic relationships within the Arvicolinae are examined based on two genes (mitochondrial cytb, nuclear GHR exon 10) and 296 morphological, developmental, behavioural, ecological cytogenetic characters. To inspect phylogenetic ‘behaviour’ of individual taxa, basic maximum‐parsimony Bayesian analyses were accompanied by experiments different data‐partition combinations, ‘slow–fast’ character weighting, inclusion/exclusion problematic taxa. Ellobius , Prometheomys Lagurus most basal...
Pleistocene mammalian communities display unique features which differ from present-day faunas. The paleocommunities were characterized by the extraordinarily large body size of herbivores and predators their structure consisting species now inhabiting geographically ecologically distinct natural zones. These probably result environmental conditions ice age ecosystems. To analyze ecological Last Glacial Recent mammal we classified into biome trophic-size categories, using Principal Component...
Abstract We examined the presence of possible Recent refugia Pleistocene mammalian faunas in Eurasia by analysing regional differences species composition, occurrence and extinction rates between Last Glacial faunas. Our analyses revealed that most widespread have survived central Palearctic continental regions, prominently Altai–Sayan (followed Kazakhstan East European Plain). The regions show compositions very similar to their counterparts. lost 12% during last 109,000 years. major...
The white rhinoceros ( Ceratotherium simum ) has a discontinuous African distribution, which is limited by the extent of sub-Saharan grasslands. southern population (SWR) declined to its lowest number around turn nineteenth century, but recovered become world's most numerous rhinoceros. In contrast, northern (NWR) was common during much twentieth declining rapidly since 1970s, and now only two post-reproductive individuals remain. Despite this species's conservation status, it lacks genetic...
Abstract The golden jackal is a mesocarnivore with rapidly expanding European range, where current resident breeding populations occupy much of the Balkans, Pannonian Basin and Black Caspian seas coasts. Despite numerous post-2000 records, this species in newly colonized regions Central Northwestern Europe remained unconfirmed. Photography- direct observation-based evidence obtained 2017 from Bohemia, Czech Republic, indicates north-western shift range over 300 km closest known population Basin.
Changes in the coat cover are important for mammalian thermoregulation. This is especially true where variable environmental conditions exist throughout seasons. Coat shedding replacement of old hair with new hair. The process differs various equids. aim study was to examine changes primitive Polish Konik horses living on a reserve southeast Poland (50.6319° N). located temperate climate. mean temperature below 0°C winter (December 8 March 9) and over 15°C summer (June September 8).

The Tragelaphini, also known as spiral-horned antelope, is a phenotypically diverse mammalian tribe comprising single genus, Tragelaphus. evolutionary history of this has attracted the attention taxonomists and molecular geneticists for decades because its diversity characterised by conflicts between morphological data well mitochondrial, nuclear chromosomal DNA. These inconsistencies point to complex ecological diversification, coupled either phenotypic convergence or introgression....
Most studies of mammal extinctions during the Pleistocene–Holocene transition explore relative effects climate change vs human impacts on these extinctions, but importance different environmental factors involved remains poorly understood. Moreover, are strongly biased towards megafauna, which may have been more influenced by hunting than species small body size. We examined potential causes linking regional characteristics with extinction rates large and mammals in 14 Palaearctic regions....
The Late Pleistocene landscape in northern Eurasia and North America was inhabited by a specific megafaunal complex, which largely disappeared during the Pleistocene/Holocene transition. Vegetation changes are considered as one of factors responsible for these extinctions, but structure composition vegetation still poorly known. Here we complement previous studies comparing taxonomic plant remains found gastrointestinal tracts frozen carcasses megaherbivores with species current Siberian...
Some of the rarest all thylacine specimens are alcohol preserved pouch young which 10 were known to exist. In November 2011, a remarkable discovery was made in zoological collection Charles University Czech Republic four at an early stage their development. These described for first time this paper.
The evolutionary history of sengis (Macroscelidea), an order Afrotheria, has been studied in last decades by molecular phylogenetic approaches. These studies proposed scenario for this group mammals and, surprisingly, revealed the presence two new genera, delimited and described five years. However, most research relied solely upon samples from Southern Africa, while genetic information East Africa Zambezian region was only fragmentary. Here, we provide complete multilocus phylogeny...
Abstract Background The behavioural repertoire of every species evolved over time and its evolution can be traced through the phylogenetic relationships in distinct groups. Cranes (family Gruidae) represent a small, old, monophyletic group with well-corroborated on level, at same they exhibit complex well-described repertoire. Methods We therefore investigated traits cranes context using several approaches two types trait scoring. more than hundred displays, almost one third which may...

The Aardvark ( Orycteropus afer ) is a very unique, but relatively widespread African mammal. Although some morphological variation has been observed between forest and savannah populations among different regions, they are all considered as single species. However, no modern taxonomic revision available. All captive aardvarks in Europe believed to stem from wild born animals Namibia, recently several new wild‐caught Tanzania have integrated into the population. This raises question, whether...
Ecotourism can fuel an important source of financial income for African countries and therefore help biodiversity policies in the continent. Translocations be a powerful tool to spread economic benefits among communities; yet, positive conservation, they require basic knowledge conservation units through appropriate taxonomic research. This is not always case, as taxonomy was considered outdated discipline almost century, some plurality approaches incorrectly disadvantage work. As example,...
