Mammal Diversity

The existence of palm oil plantation development allegedly resulted in a ecological losses, including the sustainability of mammalian diversity. So far the ecological losses to the diversity of wildlife species, especially mammals, have not been widely known. Therefore, in February 2018 a direct observation was conducted at 5 observation paths with Strip Transect Method and simultaneous data retrieval, three repetitions at 8.00-10.00 a.m. and 16.00-18.00 p.m. In addition, there are 10 Rodentia traps and 15 camera traps on each observation path. The analysis results obtained the total number of species and wealth of the highest species on oil palm plantation cover. The highest similarity index was obtained from young-aged oil palm (IS = 0.67) and the lowest commonality index was in old-aged oil palm (IS = 0.50). On the other hand, the old-aged oil palm has the highest value of mammal diversity and the lowest loss value, while the young-aged oil palm has the lowest mammal diversity value. Overall, land cover changes to oil palm plantations have a positive impact due to the addition of two species of mammals and the value of species diversity did not change significantly.

At least 251 mammal species are recorded for the Brazilan cerrado, which, therefore, is the third richest Brazilian biome. Most mammal surveys in Brazilian cerrado result from studies performed opportunistically and in short time periods. The aims of the present study were (1) provide a checklist for the mammalian fauna based on a five-year sampling in Serra do Facão region, Southeastern Goiás state; (2) compare small non-flying mammals diversity in open and forest areas and (3) compare species diversity before and after the flood caused by a hydroelectric reservoir filling. The data was gathered in 19 sampling periods, from May 2008 to September 2013. We sampled open and forest habitats and captured non-flying small mammals with Sherman and Tomahawk live traps and pitfalls; bats were sampled with mist-nets; large mammals were recorded with camera traps, and by direct observations and track surveys in field. We found 20 species of small non-flying mammals, 10 species of bats and 33 species of larger mammals. Species diversity was greater for forest than open habitats, and was also greater before than after the complete reservoir filling. About 10% of the recorded species are included in the Brazilian official list of threatened species. The total richness represents 25% of all cerrado mammal fauna, highlighting the importance of this area for regional mammal fauna conservation.

Mammal Diversity

The validity of using single-sample surveys to measure small mammal diversity was assessed by measuring the effect of short-term, temporal variation in species diversity on the spatial diversity of small mammals occupying fencerow habitats. The diversity of small mammals varied seasonally. Interaction between changes in richness and evenness accounted for the temporal variation in diversity. Temporal variation was attributed to the response of the small mammals to seasonal changes in the vegetation, to the fluctuation in meadow vole (Microtus pennsylvanicus) captures among seasons, and to the appearance of small numbers of several mammal species during the summer. Significant spatial variation in species diversity existed, but was masked by the effect of seasonal changes in habitat on the small mammals. Erroneous conclusions could therefore be drawn from the pooling of many single-sample surveys of small mammal diversity.

Mammal Diversity

Mammal groups have a vast variety of habitats, which include aquatic, aerial, arboreal, and terrestrial. For terrestrial habitats, camera traps are used as a common technique to record mammals and other vertebrates and have been recently utilized to observe arboreal animals as well. Here, we compare the difference in mammal diversity between floor and canopy strata and evaluate the use of camera trapping in a lowland forest in central Amazon. We installed nine paired camera traps, one in the canopy stratum and other in the floor stratum, in the Alto Cuieiras Biological Reserve (Brazilian Amazon). With a sampling effort of 720 camera-days, we recorded 30 mammal species: nine in canopy strata, 14 in floor strata, and seven in scansorial strata (sharing both strata). On the forest floor, the species with the greatest abundance was Myoprocta acouchy; in the canopy, Isothrix paguros had the greatest abundance; and among the scansorial species, Proechymis sp. was the most abundant. Our results show the differences in mammal diversity between floor and canopy strata; canopy strata contained more small and frugivorous mammals. Although we obtained a relatively low sampling effort with the camera-trap method compared with other studies utilizing different techniques, our results were especially similar to those of previous studies that worked with canopy and floor strata. Thus, camera trap can be very effective for recording short periods of time, and this method is less physically exhaustive and expensive for researchers to study vertical strata.

Kwatrina RT, Santosa Y, Bismark M, Santoso N. 2018. The impacts of oil palm plantation establishment on the habitat type,species diversity, and feeding guild of mammals and herpetofauna. Biodiversitas 19: 1213-1219. Indonesia is the world’s largestproducer of palm oil. Contributing 2.14% to the country’s gross domestic product, palm oil plays an important role in the nationaleconomy from plantation sector. However, the expansion of oil palm plantations has brought negative impacts to forests and wildlife.Little is known to what extent these negative impacts on mammals and reptiles can be reduced through better management. To addressthis knowledge gap, the current study assessed species diversity as affected by the establishment of the oil palm plantation in CentralKalimantan, a tropical biodiversity hotspot in Asia. We conducted 25 line transect surveys and visual encounter surveys in oil palmareas, shrubs and secondary forests in these landscapes. The results indicated that the establishment of oil palm plantation negativelyimpacted species abundance and diversity, and changed the mammal and reptile species composition, by favoring ecologically generalistspecies. For forest specialist species, forested areas like HCV and HCS, play an important role in maintaining habitat heterogeneity inoil palm landscapes. Mammal species found in habitat conditions following oil palm plantations belong to some feeding groups,whereas all species of herpetofauna have terrestrial habitat types. These mammal and herpetofauna species can live and function in thefood chain in the oil palm plantation ecosystem.
