Population status and sustainability of Yellow-crested cockatoo (Cacatua sulphurea sulphurea) on Pasoso Island, Central Sulawesi, Indonesia

Ihsan M, Mardiastuti A, Masy’ud B, Mulyani YA. 2021. Population status and sustainability of Yellow-crested cockatoo (Cacatua sulphurea sulphurea) on Pasoso Island, Central Sulawesi, Indonesia. Biodiversitas 22: 3277-3283. Yellow-crested cockatoo (Cacatua sulphurea sulphurea) is a sub-species of Cacatua sulphurea which is spread in Sulawesi and several surrounding islands, including on Pasoso Island. This cockatoo population is under tremendous pressure until categorized as critical. So far, there is no comprehensive information about population status and sustainable population size. The objective of this research area was to assess the current status or size of the population, study the size of the sustainable population and study the determinants factor of the Yellow-crested cockatoo population sustainability on Pasoso Island. The result showed that the population of the Yellow-crested cockatoo in Pasoso Island was only 3 individuals, consists of 2 adults as the parent, and 1 young individual. From 5 analyzed scenarios of the minimum sustainable population size, the 4.1 scenario is the best scenario to maintain the sustainability of the Yellow-crested cockatoo population on Pasoso Island, which is a minimum population size of four pairs (8 adult individuals). The determinants of population sustainbility analysis with the minimum sustainable population size (8 individuals or 4 pairs of broodstock) showed that inbreeding and predation as determinant factors. These factors need to be controlled through mating management and predator control by both humans and carnivorous animals.

Challenges and Way Forward for Establishing Population Based Cancer Registry in Nepal

Population Based Cancer Registry plays a crucial role in cancer control through identifying cancer incidence, mortality, pattern and trends over time in a particular population. The registry is in a very infancy stage in Nepal. During the process of establishing Population Based Cancer Registry in Nepal, the major challenges include adequate coverage of the cases, high cost of registration, sustainability along with expansion of the registry to other regions and non-linkage of Hospital Based Cancer Registry with Population Based Cancer Registry. However, the approach of mobilization of field enumerators at the end of year once had increased coverage of the cases. Similarly, the linkage of Population Based Cancer Registry with the existing Health Management and Information System will help in developing sustainable Population Based Cancer Registry and also provides an opportunity to increase coverage and expand it to other districts as well.

ASP FISH -AN EXAMPLE FOR RAPPROCHEMENT OF "LEGAL AREAS"ON LAKE BALKHASH

In the Balkhash basin, an independent sustainable population of asp fish has formed, which is of great importance in industrial and recreational fishing. In the Republic of Kazakhstan, Lake Balkhash is one of the main fishing reservoirs. In the last decade, this region has experienced a powerful diverse anthropogenic and technogenicimpact, which has led to significant negative changes in aquatic and terrestrial ecosystems. The role of the state in the regulation of environmental management and environmental protection.

The occurrence of the Lessepsian migrant Lutjanus argentimaculatus in the Mediterranean, (Actinopterygii: Perciformes: Lutjanidae) first record from the coast of Israel

Two specimens of the Lessepsian migrant, the Mangrove red snapper Lutjanus argentimaculatus are reported from the Mediterranean coast of Israel. L. argentimaculatus was first recorded in the Mediterranean in 1979 by a single specimen. Over three decades later and only in the last two years four specimens, including the two reported herein, were recorded. This pattern strongly suggests that L. argentimaculatus has established a sustainable population in the Mediterranean.
