Animal Detection for Road safety using Deep Learning

The recognition of big animals on the images with road scenes has received little attention in modern research. There are very few specialized data sets for this task. Popular open data sets contain many images of big animals, but the most part of them is not correspond to road scenes that is necessary for on-board vision systems of unmanned vehicles. The paper describes the preparation of such a specialized data set based on Google Open Images and COCO datasets. The

Seismic savanna: machine learning for classifying wildlife and behaviours using ground-based vibration field recordings

We develop a machine learning approach to detect and discriminate elephants from other species, and to recognise important behaviours such as running and rumbling, based only on seismic data generated by the animals. We demonstrate our approach using data acquired in the Kenyan savanna, consisting of 8000 h seismic recordings and 250 k camera trap pictures. Our classifiers, different convolutional neural networks trained on seismograms and spectrograms, achieved 80%–90% balanced accuracy in detecting elephants up to 100 m away, and

Anaplasma Infections In Wild And Domestic Ruminants: A Review

Anaplasma marginale can be transmitted, will grow and can survive in a large number of domestic and wild animals. It is pathogenic in cattle, and usually produces nonapparent or mild infections in other species. Anaplasma marginale has been recovered from cattle, sheep, goats, water buffalo (Bubalus bubalis), white-tailed deer (Odocoileus virginianus), mule deer (Odocoileus hemionus hemionus), black-tailed deer (Odocoileus hemionus columbianus), pronghorn (Antilocapra americana americana), Rocky Mountain elk (Cervus elaphus nelsoni), bighorn sheep (Ovis canadensis canadensis), black wildebeest (Connochaetes gnu),

Conservation Status of Giraffe: Evaluating Contemporary Distribution and Abundance with Evolving Taxonomic Perspectives

Giraffe are iconic figures across a range of African landscapes but they are currently under considerable conservation threat. Although they are widely distributed throughout 21 different countries, continent-wide populations have declined considerably over the past several decades, highlighted by the International Union for the Conservation of Nature’s (IUCN) new categorization of giraffe as a single species as “Vulnerable.” Recent genetic studies, however, propose alternative taxonomic categorizations in which giraffe are comprised of four distinct species. These proposed taxonomic classifications have

Factors Affecting the Survival of Giraffe in Ethiopia

Giraffe are social animals and non-territorial and tend to live in a small group. In Ethiopia there are two species of giraffe; the Nubian giraffe (giraffe camelopardalis) and Reticulated giraffe (giraffa reticulated) occur in southern low lands, east of Omo river including the Mago National Park, Borena and Ogden area. Giraffe populations in Ethiopia diminished over the past century in diversity, density and distribution as a result of illegal hunting, habitat degradation, civil war and unrest, the absence of a

Main threats and habitat characteristics to West African giraffes

Les girafes de l’Afrique de l’ouest (Giraffa camelopardalis peralta) vivent en petites populations isolées au Sud-est du Niger et partagent leur espace de vie avec la communauté locale. La girafe fait face à de nombreuses menaces directes et indirectes dans l’ensemble de son aire de distribution. L’objectif de cette étude est d’identifier sur le plan historique les changements et les menaces de la conservation des girafes de l’Afrique de l’ouest. Ainsi, pendant la recherche, les publications de 1970 à 2019

Leaving by staying: Social dispersal in giraffes

Dispersal is a critical process that shapes the structure of wild animal populations. In species that form multi-level societies, natal dispersal might be social (associated with a  different social community while remaining near the natal area), spatial (moving away from the natal area while continuing to associate with the same community), or both social and spatial (associating with a different community and moving away from the natal area). For such species, classical spatial measures of dispersal, such as distance moved,

An Exploratory Study into the Influence of Sex on Body Measurements, Carcass Weights and Meat Yields of Giraffe (Giraffa camelopardalis angolensis)

Various body measurements and commercial carcass yields of relatively young (2 1/2 –6 yrs old) giraffe (Giraffa camelopardalis angolensis) were investigated to quantify the effect of sex there upon. Eight male and eight female giraffe were culled by standard practice in Namibia, where body and horn measurements were taken, before the carcasses were dressed. There were no significant differences between the mean dead weights of the two sexes (bulls = 691.1 kg; cows = 636.5 kg; p = 0.096), the

Giraffe: Giraffa camelopardalis – Species Profile for Tasmania Zoo

This pest risk assessment was developed in accordance with Policy and Procedures for the Import, Movement and Keeping of Vertebrate Wildlife in Tasmania (DPIPWE 2011). These set out conditions and restrictions for importation of controlled animals pursuant to S32 of the Nature Conservation Act 2002. This document was prepared for DPIPWE use within the Department only. Giraffe are a natural curiosity and have been widely represented in captivity around the world for centuries. In Australia, they have been present in

The welfare of wild animals in travelling circuses

We were asked to provide the Welsh Government with an impartial literature review and an analysis of the scientific evidence available as to whether captive wild animals in travelling circuses and other animal shows achieve their optimal welfare requirements as set out under the Animal Welfare Act 2006 and any other relevant legislation. ◆ The Animal Welfare Act 2006 makes it a criminal offence for any person responsible for an animal to fail to provide for the animal’s welfare. Under
