Măsuri de întărire a capacității de adaptare la schimbările climatice a ecosistemelor acvatice

The current article presents a bibliographic overview of green infrastructures and their role in strengthening the adaptive capacity of aquatic ecosystems to the adverse effects of climate change (high temperatures, heavy rains, droughts). Different types of ecological infrastructures are presented: forest buffer strips, rain gardens, permeable pavement, drainage ditches; bioengineering structures for bank stabilization. Also the functions performed by green infrastructures to maintain ecosystem services were presented: mitigating the effects of floods, stabilizing banks, preventing landslides and water caused erosion, stormwater management, reducing the load of pollutants. For the implementation of this approach in the hydrographic basin of Dniester River or the Prut River a more detailed study is necessary on the state of habitats, identification of hotspot areas of aquatic biodiversity, particularly those species important for maintaining of ecosystem functions, highlighting of the areas at high risk of floods or erosion.

ROLE OF SOCIAL CAPITAL COMMUNITY BUSINESS DEVELOPMENT PROCESS AGROINDUSTRY PALM SUGAR PROTECTED AREAS IN THE FOREST BUFFER

The study aims to determine (1) the state of social capital businesses agro-industry palm sugar in the buffer zones of protected forest sub district of Bulango Ulu Bone Bolango regency, (2) the state of the business development agro-industry of palm sugar in the buffer zones of protected forest sub district of Bulango Ulu Bone Bolango regency, (3) the role of social capital for the development of agro-industrial enterprises palm sugar in the buffer zone of protected forests Bulango Ulu sub district Bone Bolango regency. This research is quantitative. Sources of data in this research are secondary data from the primary data from questionnaires to farmers. The data analysis technique used is descriptive statistics and regression. These results indicate that (1) Social capital is owned by farmers in a fairly good state because it has an average value of 83.32%. This shows that people in a community of palm sugar craftsmen were able to cooperate with each other and mutual cooperation in achieving the common good in a business that was involved. (2) The Palm Sugar Agro-industry business development in the area of protected forest buffer Bulango Ulu sub district Bone Bolango regency has been running quite well because it has an average value of 76.76%. (3) In partial and simultaneously social trust, social norms, social networks and local wisdom a significant effect on the business development process agro-industry of palm sugar in the buffer area of protected forests Bulango Ulu sub district Bone Bolango regency the determinant value of 79.90%.

The response of mixed-species bird flocks to anthropogenic disturbance and elevational variation in southwest China

Avian mixed-species flocks (MSFs) are an important example of species interactions threatened by the biodiversity crisis. They are found throughout the world in forested habitats but are generally reduced in size or frequency by human disturbance. In southern China, a unique MSF system is led by several species of closely- related fulvettas (Alcippe morrisonia, A. hueti, and A. davidi). Our objective was to understand how this system is distributed across elevational gradients, especially moving west into the Hengduan Mountains, and how it responds to human disturbance. We sampled leadership and composition of 375 MSFs over 2 yr in and surrounding 5 nature reserves in Guangxi Zhuang Autonomous Region and Yunnan Province, with transects placed in different land use types—protected forest, buffer areas, or agriculture—and ranging from 400 to 3,200 m. We also sampled birds outside of MSFs. We found MSFs led by fulvettas (A. fratercula and A. davidi) in forests across the region up to 2,900 m. Elevation was not a significant influence on MSF size or prevalence in models that also included land use. We found that MSFs were encountered at only one-third of the frequency in agriculture as in forest, and had strongly different composition and leadership. Although MSFs in buffer areas were more similar to those in forest, birds in buffer areas had lower flocking propensity, different flock leaders, and less complex social networks. In particular, buffer transects that were seeded pine had low numbers of fulvetta-led MSFs and forest specialists in MSFs. In the future, it is important to understand which vegetational characteristics allow MSFs, particularly fulvetta-led MSFs, to persist in buffer habitats.

This study was to investigate the endemic birds, local knowledge and the conservation efforts on the bird species. The study was conducted in the period from February 2007 to May 2008. Methods used including observation, interviews, documentation, description and literature review. The results showed that there were 11 spesies of endemic birds occured in Soaib village: Cassowary (Casuarius unappendiculatus), Yellow-crested Cockatoo (Cacatua galerita), two species of Megapodes; (Aypepodius arfakianus) and (Megapodius freycinet), Papuan Hornbill (Rhyticeros plicatus), Victoria Crowned-pigeon (Goura victoria), Palm Cockatoo (Prombosciger atterimus), Parrot (Psittrichas fulgidus), Papuan crow (Cracticus cassicus) Bird of Paradise (Paradiseae sp). Local people determined the forest in three different types; primary forest, buffer zone between primary and secondary forest and secondary forest. Primary forest was being the habitat for 11 endemic birds. These birds were hunted by local people for meat consumption and cultural purposes excepted the Papuan hornbill (Rhyticeros plicatus) and Papuan crow (Cracticus cassicus). Bird of Paradise (Paradiseae sp), and yellow-crested Cockatoo (Cacatua galerita) were captured to be sold in the market. This was happened because of lack information and education about the role of the birds in forest ecosystem. Key words: Traditional conservation, endemic birds, Soaib village, Jayapura
