Abstract
Urbanisation alters ecological processes and reshapes biodiversity patterns, with significant implications for bird communities. This study examined avian community structure across an urban gradient in Daerah Istimewa Yogyakarta, Indonesia, by integrating field surveys with remotely sensed environmental variables. Bird species richness and composition were assessed at 300 observation points stratified by urbanisation class. Environmental predictors, including vegetation cover and land surface temperature, were derived from Landsat 8 imagery. A Generalized Linear Mixed Model (GLMM) was used to identify key environmental drivers, accounting for spatial clustering within 2×2 km grids. Model selection via backward stepwise elimination revealed that bird species richness was positively associated with vegetation cover and negatively influenced by surface temperature. These results highlight the ecological importance of vegetation in urban landscapes and the adverse impacts of urban heat on biodiversity. Enhancing green infrastructure and maintaining vegetation cover are essential strategies to support avian diversity in rapidly urbanising regions.

IMPACTS OF BIMATURISM AND FRUIT AVAILABILITY ON THE BEHAVIOUR OF MALE SUMATRAN ORANGUTANS, Pongo abelii LESSON, 1827 (PRIMATES: HOMINIDAE)

Abstract
Adult male orangutans can be described as flanged and unflanged, which are two morphologically distinct stages of sexual maturity (bimaturism). Bimaturism influences male orangutan behaviour, though specific effects remain unclear. This study examines the behavioural ecology of adult male Sumatran orangutans in Suaq Balimbing, Sumatra. We found that both male morphs spent over 60% of their time feeding, but unflanged males engaged in significantly more social interactions than flanged males. The diets of both morphs were mostly composed of fruit, and there were no significant differences in the proportions of time spent feeding on different types of food. Unflanged males travelled significantly longer distances, likely to access more dispersed food sources and social opportunities. With increasing fruit availability, social interactions and daily travel lengths of unflanged males decreased, whilst social interactions and daily travel lengths of flanged males increased. These results shed novel light on how male orangutans adjust their behaviour in response to ecological factors.

A NEW DAY GECKO OF THE Cnemaspis podihuna (REPTILIA: GEKKONIDAE) CLADE FROM NORTHEAST INDIA

Abstract
We describe a new species of Cnemaspis from Assam, a valley of an antecedent river, the Brahmaputra, in northeastern India that belongs to the C. podihuna species group. The new species is the second Cnemaspis reported from the mainland Indian subcontinent, representing the entire podihuna clade. It is small (SVL 30.8–35.7 mm) and diurnal. The new species is genetically and morphologically allied to C. assamensis in northeast India, and also morphologically allied to the members of the C. podihuna group in Sri Lanka, especially to C. molligodai and C. manoae, but is distinguished by its larger body size but with lower number of midbody scale rows, higher number of miventrals and ventral scale rows across the belly, no tubercles on lower flanks, three enlarged rows of thigh scales parallel to the enlarged femoral scale row, and fewer poreless scales separating precloacal and femoral pore scales in males. The new species is also genetically divergent from C. assamensis by p-distances of 6.0–7.2% and from Sri Lankan congeners by 21.2–24.8% in the mitochondrial ND2 gene. With this new species, only two species of Cnemaspis are now known from the podihuna clade in India, but additional species likely remain unrecognized.

Abstract
A new amphidromous goby species of the genus Stiphodon Weber, 1895, is described based on eight specimens collected from Enggano Island, Indonesia. A combination of the following characteristics distinguishes the new species from all other congeners: form of the fourth dorsal spine of the first dorsal fin group elongated, filamentous and without membrane, spotting on head and fin, preanal length 49–55% of standard length (SL), second dorsal length 38−45% of SL, anal fin length 42−47% of SL, caudal fin length 30−34% of SL, number of premaxilary teeth ranging from 25−33, canine-like teeth 2−5, number of scales in transverse forward series 5−9, number of scales in zig-zag series 5−8.

Abstract
Human-snake interactions are one of the most common forms of human-wildlife conflict since many snakes are known to be adapted to anthropogenic environments. We gathered evidence from social media and online newsletters on conflicts among 109 species, 56 genera, and 12 families throughout 38 provinces in Indonesia between 2015 and 2023. West Java emerged as a hotspot for human-snake conflicts, followed by other regions on the island of Java. Malayopython reticulatus had the highest conflict rates in Indonesia (n=165, 8.81%) and had the highest tendency to enter human settlements (n=138, 10.92%). Naja sputatrix is reported to have the highest rates of being killed (n=44, 11.76%), while Calloselasma rhodostoma[/]i and [i]Trimeresurus insularis are reported to show the highest incidence of bites (both n=37, 16.30%). Our data provides fundamental information for the Indonesian government to inform human-snake conflict mitigation programs.
