The Spatio-Temporal System of Giraffes (Giraffa camelopardalis, Linnaeus, 1758) in the Osnabrück Zoo / Über das Raum-Zeit-System von Giraffen (Giraffa camelopardalis, Linnaeus, 1758) im Zoo Osnabrück

The study aimed at spatial-temporal behaviour and possible path-use of zoo-giraffes (Osnabrück Zoo). Another aim was to reveal possible connections between external factors and the spatial behaviour of the animals. Results should be used for the restructuring of the giraffes’ outdoor enclosure as well. The herd consisted of one bull, three females and one calf. Data recording took place in July/August 2014 (ca. 170 observing hours, > 2000 scan-points recorded). The animals were observed by scan-sampling-method. For path-use animals were

Immunocontraception of male and female giraffes using the GnRH vaccine Improvac®

The aim of this study was to develop protocols for contraception in both sexes of giraffes (Giraffa camelopardalis) by using the GnRH vaccine Improvac®. We evaluated the success of immunization by analyzing fecal reproductive hormone metabolites in female (n = 20) and male (n = 9) giraffes. Endocrine analysis provided the basis for the successful immunization protocol, as well as for assessing long‐term effects. Reliable reduction of fecal steroid metabolites to baseline levels in female giraffes was achieved with three,

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

Automated camera trap species recognition made easy: Using entry-level hardware and few training data

Computer vision methods used to analyse camera trap photos are usually computationally expensive, require large training datasets and typically focus on only one species per photograph or rely on static backgrounds between sequential images. In contrast, our proposed method requires only an entry-level computer and relatively few training data while handling multi-species photos with changing backgrounds. It is able to distinguish between four large mammal species common to the Iona–Skeleton Coast TFCA, namely giraffe, impala, oryx and zebra. Trained on

Illegal Hunting & The Bushmeat Trade In Savanna Africa: Drivers, Impacts & Solutions To Address The Problem

In this report, the term ‘bushmeat’ is used to denote meat from wild animals that have been hunted illegally, which aside from being used for personal consumption, is often sold commercially. The bushmeat trade has long been recognized as a severe threat to wildlife populations in the forests of West and Central Africa and is considered a conservation crisis in that biome. Far less attention has been focused on the issue in African savannas, perhaps due to a misconception that

Focus on the Positives: Self-Supervised Learning for Biodiversity Monitoring

We address the problem of learning self-supervised representations from unlabeled image collections. Unlike existing approaches that attempt to learn useful features by maximizing similarity between augmented versions of each input image or by speculatively picking negative samples, we instead also make use of the natural variation that occurs in image collections that are captured using static monitoring cameras. To achieve this, we exploit readily available context data that encodes information such as the spatial and temporal relationships between the input

Mammal Species Richness at a Catena and Nearby Waterholes during a Drought, Kruger National Park, South Africa

Catenas are undulating hillslopes on a granite geology characterised by different soil types that create an environmental gradient from crest to bottom. The main aim was to determine mammal species (>mongoose) present on one catenal slope and its waterholes and group them by feeding guild and body size. Species richness was highest at waterholes (21 species), followed by midslope (19) and sodic patch (16) on the catena. Small differences observed in species presence between zones and waterholes and between survey

Wildlife utilization: use it or lose it- a Kenyan perspective

The history, present status, plans for the future and constraints of consumptive utilization of wildlife in Kenya are discussed. Such utilization is considered to be a viable development option and has positive aspects for conservation of the environment and animals. It is proposed that illegal consumptive utilization is at such a level in the country that if it is not brought under control the wildlife population will decline catastrophically. There are numerous constraints of a legal and infrastructural nature which
