“…We observed insignificantly higher avian richness and diversity in the summer (n = 80, H s = 3.95) than in the winter season (n = 72, H w = 3.76), whereas bird abundance was higher in the winter than in the summer. Contribution of the seasonal migrants to higher richness and abundance of birds in a particular season has been observed in multiple studies at varied geographical conditions (Werema and Howell 2015;Gomes et al 2017;Tzortzakaki et al 2017;Muhammad et al 2018), however, such effects are not prominent when a majority of the avifauna is dominated by common resident birds (Nam et al 2019). Small seasonal variation on the abundance of birds in the study area might be accounted for the larger proportion (71.4%, 80/112) of the residential species.…”

Background: Patterns of biological diversity and richness can vary along the elevational gradients among mountain systems making it difficult to conclude the general pattern. The drivers of such pattern are also poorly known in the southern flank of the Himalaya due to limited studies. Therefore, we assessed the species richness, seasonal patterns and drivers of avian diversity along an elevational gradient on Mardi Himal trekking trail, a newly open tourist route in Annapurna Conservation Area of the central Himalaya. Methods: Two surveys (winter and summer seasons of 2019) were conducted from the bank of Seti-Gandaki River confluence (1030 m above sea level, asl) up to the Low Camp (3050 m asl) of the Mardi Himal. The point count method was employed in every 100 m rise in the elevation. Diversity indices were calculated and bird abundance data on species, sites, seasons and environmental variables were analyzed. Generalized linear model, polynomial regression and ordinary least square regression were performed to examine the importance of environmental factors in shaping the avian richness pattern. Results: A total of 673 individuals of birds belonging to 112 species, of which 72 in winter and 80 in summer, were recorded. We observed a hump-shaped pattern of the overall species richness along the elevational gradient. The richness pattern remained consistent even when explored by season, for winter and summer separately. Diversity indices were found higher during the summer. Elevation and mean monthly temperature in both seasons showed non-linear relation with avian species richness. Precipitation exhibited positive association in summer whereas the same in winter was negatively correlated with avian species richness. Distance to the nearest water source and the nearest human settlement were negatively correlated with the richness of birds. Small-ranged and insectivorous birds were under the strong influence of gradients on climatic variables like temperature and precipitation. Conclusions: We conclude that the combined effects of multiple factors such as area, gradients of climate (i.e. temperature and precipitation), resource availability and disturbance play an important role in bird diversity and richness pattern along an elevational gradient of a montane environment in Mardi Himal.

“…There are about 360 small volcanoes known as "Oreum". Oreums are distributed mainly in the middle mountain zones [17] that provide retreat sites for snakes. The highest peak on the island is 1950 m above sea level.…”

Understanding the ecology of species at risk is extremely important for their conservation and management. Due to land clearing for urban expansion, agriculture, and the import of pets, several snake species including the red-tongue viper (Gloydius ussuriensis) on Jeju Island of South Korea, have become threatened. We studied morphology, distribution, habitat characteristics, diet, and reproduction of red-tongue viper to provide a higher understanding of species ecology. This species on average reach 242–580 mm snout-vent length and is found in a wide range of habitat from mountain forest to lowland areas. Adult snakes prey almost entirely on amphibians followed by mammals and centipedes. The mating usually takes place in spring and birth takes place in autumn. This study points out the major threats and ill-information if addressed will not only contribute to the conservation efforts but also improve the negative attitudes that people hold toward these fascinating animals. The ecological data of G. ussuriensis herein provides basic information which assists in designing the management technique for conservation. Similar applications may be generalized and used to other vulnerable species to detect and quantify population ecology and risks, bolstering conservation methods that can be used to optimize the efficacy of conservation measures.

“…8. The oreums labeled as 1 in the figure, a common name for a volcanic cone in Jeju Island (Nam et al, 2019), are visible as small, scattered circular shapes with high scores; Gotjawal, labeled as 5 in the figure, is a uniquely formed forest vegetation found on lava terrain (located at the eastern and western parts of Jeju Island (Kang, Kim & Kim, 2013)). On the other hand, developed areas such as roads and the central town of Jeju city and Seogwipo city appear to have relatively low landscape conservation value.…”

Understanding landscape as a socio-ecological system where systematic interactions occur among diverse ecosystems and human society is necessary for a sustainable landscape and resource management. However, many countries with rapid economic growth, including South Korea, depend on conventional planning and policy decisions to meet increasing demands for the use of specific natural resources. Such resource-oriented planning and policy which neglect considerations for the surrounding landscape can result in conflicts of interest and regulation. We designed a landscape conservation value (LCV) map of Jeju Island, Korea to overcome rising managerial and policy issues with the provision of systematic perspectives of landscape. With a consideration for natural and human-modified characteristics of the landscape, we used landform and land cover data to create fundamental landscape types. Then, the LCV was assigned to each type by a board of landscape experts. Within a study region, we observed relatively high values in registered protected areas and unique landscapes, and areas where high and low values are aligned. The resultant LCV map can identify areas that potentially require an integrated approach to prevent adverse effects caused by a conventional approach.
