Gran Paradiso National Park

The last Capricorns (Capra ibex ibex) in the Alps survived during the nineteenth century in the Aosta valley thanks to the royal hunting reservation (today Gran Paradiso national park). Capricorns from this reservation were successfully re-introduced in Switzerland after its Capricorn population had disappeared. Currently in Switzerland there are 13200 Capricorns. Every year 1000 are hunted in order to prevent a large variation and overaging of their population and the damage of pasture. In contrast, in the Gran Paradiso national park the game population regulates itself naturally for over eighty years. There are large fluctuations in the Capricorn population (2600–5000) which are most likely due to the climate, amount of snow, population density and to the interactions of these factors. The long-term surveys in the Gran Paradiso national park and the investigations of the capacity of this area are a valuable example for the optimal management of the ibexes in Switzerland.

AbstractOcelots were historically hunted for their skins but habitat loss is now their most serious threat, causing rapid declines in populations throughout their range. Ocelot abundance has been estimated for various locations across the Neotropics, but we still lack this information from some countries, including Ecuador. Knowing whether ocelot abundance is increasing or decreasing is important to assess the conservation status of this species and the conditions of its habitats in the Ecuadorian Amazon and in the region. To determine whether ocelot abundance and its behavior are affected by human-related activities, camera-trap surveys were carried out in two localities of Yasuní National Park (YNP), one that has experienced hunting, oil extraction, and roads (Maxus Road) and one that is largely unaffected by these activities (Lorocachi). During the survey, 35 and 36 individual ocelots were photographed in Maxus Road and Lorocachi, respectively. Population density estimates were similar for both localities, ranging from 0.31 (SE±6) to 0.85 (SE±17) ocelots/km

Borneo has wide land that support high biodiversity. One of them is Tanjung Puting National Park (TPNP), which have biodiversity such as terrestrial mammalian carnivore. Carnivore has a role to maintain its ecosystems. But, there are no data for population density of terrestrial mammalian carnivore. The object of this research is to find out population density of terrestrial mammalian carnivore in Camp Leakey, TPNP, Central Borneo. This research accomplished in September-October 2015 in Camp Leakey. Using line-transect sampling. Data collection was accomplished at 18.00-24.00 Central Indonesian Time (WITA) on eight transects with three times replication by direct surveys and indirect surveys. This research has obtained five species, malayan sun bear (Helarctos malayanus), sunda clouded leopard (Neofelis diardi), leopard cat, and group of civet, like small-toothed palm civet (Arctogalidia trivirgata) and asian palm civet (Paradoxurus hermaphroditus). Population density of each species from the highest to the lowest is 13,5 Individual of leopard cat/km2, 9,84 Individual of malayan sun bears/km2, 4,31 Individual of sunda clouded leopard/km2, and 3,65 Individual of civet/km2. Malayan sun bears, sunda clouded leopards and civets prefer to be in land forest. Leopard cats prefers to be in transition forest.

This project was designed to determine the optimum population size for bison in the Theodore Roosevelt National Park (TRNP) by fulfilling the following objectives: 1. Delineate primary and secondary bison ranges; 2. Determine forage productivity for major range sites within primary and secondary use areas; 3. Determine the general seasonal food habits of bison in TRNP; 4. Determine range condition under present population density of bison and the maximum carrying capacity of primary use areas; and 5. Integrate range condition and carrying capacity estimates with management priorities for bison on the TRNP.

 Hispid hare (Caprolagu shispidus) is an endangered lagomorph which had a wide range of distribution in the past, but currently it is known to occur only from few isolated tall grass pockets of India and Nepal. We explored the population status, habitat utilization and existing threats of the Hispid hare at Shuklaphanta National Park (SNP) by the strip transect and quadrate sampling methods from November 2015 to May 2016 covering both winter and summer seasons. Four study sites of total 1.58ha were selected within SNPand strip transects were randomly laid to determine presence and absence of pellets of Hispid hare and their counts were used to estimate the population density. The Population density of Hispid hare was found to be 0.1820/ha in winter and 0.2268/ha in summer with the statistically significant preference to the tall grassland habitat. Twelve grass species were identified in the habitat of Hispid hare with dominancy of Saccharum spontaneum, Imperata cylindrica, Narenga porphyrocoma, and Saccharum munj. Among the grasses, Imperata cylindrica and Narenga porphyrocoma were the food species of higher preference for Hispid hare.

Feeding Resources

Previous studies have shown that the rabbit (Oryctolagus cuniculus) is the main prey of the Black Kite (Milvus migrans) in Matasgordas (Doñana National Park, southwestern Spain), and that the reproductive success of pairs is enhanced with increasing rabbit consumption. In our study area, rabbits live mainly in large warrens patchily distributed across the breeding area of Black Kites. Rabbit consumption was higher for Black Kite pairs having warren entrances close to their nests. During the 3 years of the study, this population of Black Kites suffered a considerable increase. New pairs in the area selected nesting trees inside areas with a high density of rabbits. The pattern of Black Kite aggregation in our study area, where they breed in a "colony" with a population density among the highest recorded, can be explained, at least partially, by rabbit aggregation. Defense of feeding resources could help to explain the territorial behavior of Black Kites. Coloniality and feeding territoriality are not mutually exclusive.

The aim of this study was to develop better techniques for controlling feral pigs, Sus scrofa, in the event of an outbreak of an exotic disease than the use of 1080. Trail-baiting with warfarin-treated wheat killed 30 of 32 feral pigs carrying radio transmitters in Namadgi National Park, A.C.T., in May 1986. The casualties took 9.7 � 0.4 (mean � s.e.) days to die (range 6-14) and all died within 2.06 km of the bait trail. The two survivors (both males) were radio-located within 339 m of the poison trails several times, but then moved 5.1 and 1.5 km, respectively, out of the trial area. Home ranges averaged 4.7 � 0.6 km2 (range 0.7-22.6) and the population density was approximately 2 km-2. The pigs' mobility did not alter as death approached. They moved equal distances during the day and the night. Differences in mobility between the sexes were generally minor.
