Migratory Pattern

We studied from 1993 to 2002 the spatial organization of visually marked females in an isard ( Rupicapra pyrenaica Bonaparte, 1845) population in the Pyrenees National Park. In winter, all individuals were concentrated within the same 3.7 km2 refuge area. In summer, two patterns of space use were recorded: sedentary females (n = 33; 52.2%) remained within the refuge area, whereas migrating females (n = 29; 46.8%) summered outside the refuge area, at a horizontal distance of 1.4–9.2 km and 300–800 m higher in elevation than their winter ranges. Females were faithful to their seasonal ranges. The population was organized in well-defined spatial units in summer. This organization was roughly preserved in winter, despite the spatial concentration of the individuals by this season. The resulting spatial clustering might reduce spatial competition and pathogenic contamination between groups, allowing the maintenance of high population density. The appearance of a migratory pattern occurred probably as a result of the protected status of the species, which allowed the population to increase. Some individuals dispersed as a result of the population density increase. The two recorded patterns of space use likely arose from spatial attachment and social affinity that developed in the first years of a female’s life, and could explain the coexistence of the two spatial patterns.

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.

There is geographical variation in the ways in which people think, feel, and behave. How are we to understand the causes and consequences of such variation? Geographical psychology is an emerging subarea of research concerned with the spatial organization of psychological phenomena and how individual characteristics, social entities, and physical features of the environment contribute to their organization. Studies at multiple levels of analysis have indicated that social influence, ecological influence, and selective migration are key mechanisms that contribute to the spatial clustering of psychological characteristics. Investigations in multiple countries have shown that the psychological characteristics common in particular regions are respectively linked to important political, economic, and health indicators. Furthermore, results from large multilevel studies have shown that the psychological characteristics of individuals interact with features of the local environment to impact psychological development and well-being. Future research is needed to better understand the scale and impact of person-environment associations over time.
