Abstract

ABSTRACT Muaro is one of the water bodies in which a variety of living organisms, the organism is clam shells Polymesoda bengalensis is known by the public as the seashell. The shells used by people around for a living because of the economic and nutritional value is very high. Current where abouts shellfish habitat Polymesoda bengalensis already disturbed. The most serious threat to the population is the result of harvesting clams and mussels taking excessive. Organisms that live in Muaro depending on substrate conditions and salinity, the salinity fluctuations depending on topography estuaries and tidal influence, the substrate  showed  differences  with  population densities. This factor  caused by  each type of  substrate occupied by Polymesoda bengalensis shells with different age groups. This study aimed to determine the distribution of oyster shell length and physical factors-water chemistry of mangrove clams Polymesoda bengalensis in Muaro Nipah Kecamatan Sutera Kabupaten Pesisir Selatan. The research was conducted in  January  2013  in  Muaro  Nipah  Kecamatan  Sutera  Kabupaten  Pesisir  Selatan.  Analyzes  were Polymesoda bengalensis conducted in the laboratory Animal Ecology Department of Biology, Faculty of Mathematics  and  Natural  Sciences,  Andalas  University  in  Padang,  this  determination  using  survey methods and sampling techniques using purposive systematic stratified random sampling in three locations determined by vegetation. Results of sample analysis shells Polymesoda bengalensis obtained size comparison long: thick : high = 2 : 1 : 2, there is a close relationship between the length and height with thick shells Polymesoda bengalensis. Biomass of meat is determined by the length, thickness and height shells. Length ranged shells 2.9–7 cm.

Abstract

Rimbo Panti Nature Reserve is a conservation area located in West Sumatra which consisted of two main habitat types, dry hilly and swampy forest habitat types. These forest types potentially board many species of mammals. This research was conducted from December 2015 to March 2016 in The Nature Reserve to determine the diversity of mammals occupied each type of habitats. Twenty two camera traps were installed in pairs, six pairs in the dry hilly habitat (574-871 m asl) and five pairs in the swampy habitat (216-261 m asl). From a total 109 photos, 17 species were identified, consisted of 11 species from hilly and 10 species from swampy forest habitat. There were four species found in both habitat types. Shannon-Wiener diversity index showed that mammalian diversity of Rimbo Panti Nature Reserve is moderate (H’=1.95) while mammalian diversity in swampy forest (H’= 2.06) was higher than hilly habitat forest (H’=1.54).

Abstract

A study on social network based on grooming interactions among males of long-tailed macaques (Macaca fascicularis) at Gunung Meru, Padang has been conducted from August to October 2015. The dominance relationship determined by submissive interactions among 17 adult males. Submissive interactions were recorded using ad libitum observation and grooming interactions by continuous recording method. The results showed that the dominance hierarchy among males was linear (Matman linearity index: h' = 0.97). Alfa male appeared to have the highest centrality index among all the males. This study indicates that individuals attained higher dominance hierarchy tend to have higher degree of centrality.
