Book excerpt: Master's Thesis from the year 2011 in the subject Nature Protection, Landscape Conservation, grade: 1,3, Christian-Albrechts-University of Kiel (Institut für Natur- und Ressourcenschutz Abteilung Landschaftsökologie), course: Environmental Management, Umweltmanagement, language: English, abstract: The stock of the European brown hare (Lepus europaeus PALLAS, 1778) is declining since decades, in Germany as well as in other European countries.At the same time,the occurrence of European brown hares is a new phenomenon in urban areas. Hence,Lichtenberg, a city district of Berlin, the capital of Germany, even assumed a special responsibility for its new inhabitants. Whereas a method for the quantification of this common game species in agricultural areas already exists, a new quantification method for city habitats is required in order to overcome several limitations. The aim of this master thesis is to deliver a suitable quantification method for Lepus europaeus, which can be applied by nature conservation authorities in future. By means of a strong LED torchlight and a bike, 153.74 ha of green area, which is usually scattered between residential buildings, were investigated in the style of the previous “spotlight taxation”. These investigated areas belong to five different tracks. Each track was investigated three times in the late evening hours in the spring period from 8th of March until the 25th of April 2011. Within this time 37 sightings of hares have been made. Summing up the five maximum values from each of the 3 countings, one could assume that at least 17 hares live within the illuminated area. Considering the territorial behaviour, even a minimum number of 19 hares is probable. If additionally only suitable tracks are taken into account, a density of 16.98 hares/100 ha can be calculated ‒ a surprisingly high value compared to the results of spotlight counting in surrounding federal states, where the agricultural landscape, and therefore the natural habitat of Lepus europaeus, is more prevalent. However, a direct comparison to the hare densities in the open landscape, which are obtained by means of different methods is incorrect. Nevertheless, if the proposed aspects for a future implementation will be taken into consideration in the long run, it is a realisable method for the quantification of urban hare populations. Moreover, the interested public can participate on this scientific approach as well. Then, cost reduction and the rising awareness for wild animals in the public are positive side-effects.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The declines of the brown hare (Lepus europaeus), a priority species for conservation in the UK, may have been caused by changes in agricultural management. This study aims to identify hare distribution, density, habitat selection and demography in grass lands in order to benefit their future conservation. In addition, this study aims to investigate the impact of current agricultural management on the populations of the European wild rabbit (Oryctolagus cuniculus), a major agricultural pest and potential competitor for hares. Hare and rabbit populations were surveyed in several large, pasture-dominated, sites in north -east England between 2007 and 2009. Estimated density of brown hares in the studied region was far higher than the published national average density for this species in pastures but with very large variation between superficially similar sites. We explored a new method to survey hares using night-time line transect distance sampling and compared this method with day time surveys. Night-time distance sampling produced improved precision estimates of hares with considerably less survey effort by maximising detectability during surveys. Hares and rabbits had different habitat requirements in grassland areas and areas dominated by intensive sheep grazing produced the lowest hare densities and in most cases were associated with high rabbit densities. Field size was an important determinant of the distribution of both hares and rabbits but with contrasting effects for the two species. Predator control appeared more important in increasing rabbit numbers than hares in the studied region. Our results indicate that recent changes in pasture management in the UK might favour high rabbit densities with potentially significant economic impacts for the agricultural sector. Hare productivity was high but female fertility and survival, in particular juvenile survival, were relatively low. Hares in the studied region were generally in good condition and reached sizes comparable with hares from arable areas. Population modelling suggested the hare population in the area was slowly increasing but was susceptible to decline even at relatively moderate levels of hunting. Radio-tracking indicated that habitat heterogeneity was important for hares at both between and within field levels. Hares preferentially used field margins during both active and inactive periods and selected woodland edges and unimproved grassland during diurnal periods, suggesting that they might benefit from measures designed to increase heterogeneity and re-establishment of non-farmed habitat features, particularly field margins. Equally, hares avoided sheep grazed fields with short swards for both foraging and resting indicating that reducing grazing intensity in pastural areas would also be beneficial for hare conservation. We suggest that grassland management could be adapted in order to minimize damage by high numbers of rabbits and increase the presence and abundance of the brown hare, a species of conservation concern in Europe and the UK.

This book was released on 1992 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behaviour of the brown hare (Lepus europaeus) was studied on the Somerset levels, U.K., between 1977 and 1987. The hare is exclusively nocturnal when nights are longest and part-diurnal when they are shortest but the transition is not smooth. There is a linear dominance hierarchy between bucks. The nearer a doe is to oestrus, the higher the rank of her escort. Some pre-partum does monitor the prospective birthsite. They are only occasionally escorted by bucks. In contrast, a non-monitoring pregnant doe was regularly escorted. Does lie up within 250m of their litters but take a more circuitous route when visiting them and 'detour when foxes are encountered. Four Autumn litters were suckled for between six and nine weeks. Sucking leverets usually sniff-noses when meeting up, followed by a short period of locomotor play after which they go quietly to the nursing point. Some weaned leverets continued to meet up. The principal component of locomotor play is 'streaking' - running top speed back and forth down a familiar route. Leverets disperse after nursing to a daily increasing extent. Leveret distress screams were audible from a distance of 550m. As a visible signal, the buck's white tail flag seems to serve no purpose. The doe uses her tail flag to lead her litter. Only does shake their tails which they do exclusively in the near presence of bucks; the bucks then sniff the ground underneath. Hares were not observed to signal to each other by body postures or to use their ears for purposes other than acoustic. Does convey a threat to bucks by flattening their ears and lifting their muzzles. Adults, particularly bucks; sniff a partner's nose for olfactory information as an alternative when the ano-genital region is inaccessible, but are frequently threatened when so doing. All chin-marking was by bucks of which 80% were solitary. Hares approached in the open by foxes stand bipedal when, on average, the fox is about 30m distant. The relevance of the behaviour patterns are discussed.

Book excerpt: Die vorliegende Arbeit beschäftigt sich in diesem Zusammenhang mit der Ermittlung von European Brown Hare Syndrome (EBHS) - Infektionsgrade, Infektionswahrscheinlichkeit und deren Beziehungen zu Populations- und Umweltfaktoren sowie der Infektions- und Mortalitätsrate durch das EBHS- Virus in Hasenpopulationen in Deutschland. In den Jahren 1989 und 1990/91 wurde das EBHS aus 27 verschiedenen Regionen der Bundesländer Niedersachsen, Nordrhein-Westfalen, Schleswig-Holstein, Mecklenburg- Vorpommern, Sachsen-Anhalt und Thüringen untersucht. Diese Regionen wurden zu acht Untersuchungsgebieten zusammengefasst: westliches Untersuchungsgebiet, Hildesheimer- Braunschweiger Börde, südniedersächsischer Raum, nördlicher Raum, nordöstliches Untersuchungsgebiet, Magdeburger Börde, Thüringer Becken und Niederrhein. Insgesamt wurden 1330 Blutproben Hasen aus 35 Treibjagden in der Zeit vom 23. November bis 27. Dezember 1989 und vom 24. November 1990 bis 5. Januar 1991 untersucht. Von jedem Tier wurde Körpermasse, Geschlecht (anhand der äußeren Geschlechtsmerkmale) und Alter (mit Hilfe des Strohschen Zeichens) ermittelt. Außerdem wurden die Augäpfel entnommen, um das Alter des Tieres in Tagen festzustellen. Bis zur Diagnose im Jahr 2003 wurden die Plasmaproben in Schraubgefäßen bei -200 C tiefgefroren. 1202 Blutproben von insgesamt 1202 geschossenen Hasen konnten mit dem Enzyme- Linked-Immunosorbent-Assay Test (ELISA- Test) und dem Nachweis von Antikörpern gegen das EBHS- Virus untersucht werden. Bei 808 Blutproben (67,2 %) konnte aufgrund der Bildung von Antikörpern gegen das EBHS- Virus nachgewiesen werden, dass die Tiere mit dem Virus in Kontakt gekommen waren.
