Varying with altitude and rainfall of two forest types of tropical forest were studied. Community wide pattern in both vegetative and reproductive phenophases among various tree species of Bhadra wildlife sanctuary, Karnataka is reported here. Leaf initiation peaks in the month of April in dry forest, after leaf less period of 1-2 months, in evergreen forest leaf initiation peaks in the month of January simultaneously with leaf senescence. Flower initiation begins from January till June with a peak in April in dry forest. Evergreen forest starts from November to march with a peak in January and February. Fruit maturation in dry forest starts from March to December with a peak in August and November, in evergreen forest from January to July with a peak in April.DOI: http://dx.doi.org/10.3126/on.v9i1.5738

Abstract. Isoprene fluxes vary seasonally with changes in environmental factors (e.g., solar radiation and temperature) and biological factors (e.g., leaf phenology). However, our understanding of the seasonal patterns of isoprene fluxes and the associated mechanistic controls is still limited, especially in Amazonian evergreen forests. In this paper, we aim to connect intensive, field-based measurements of canopy isoprene flux over a central Amazonian evergreen forest site with meteorological observations and with tower-mounted camera leaf phenology to improve our understanding of patterns and causes of isoprene flux seasonality. Our results demonstrate that the highest isoprene emissions are observed during the dry and dry-to-wet transition seasons, whereas the lowest emissions were found during the wet-to-dry transition season. Our results also indicate that light and temperature cannot totally explain isoprene flux seasonality. Instead, the camera-derived leaf area index (LAI) of recently mature leaf age class (e.g., leaf ages of 3–5 months) exhibits the highest correlation with observed isoprene flux seasonality (R2=0.59, p<0.05). Attempting to better represent leaf phenology in the Model of Emissions of Gases and Aerosols from Nature (MEGAN 2.1), we improved the leaf age algorithm by utilizing results from the camera-derived leaf phenology that provided LAI categorized into three different leaf ages. The model results show that the observations of age-dependent isoprene emission capacity, in conjunction with camera-derived leaf age demography, significantly improved simulations in terms of seasonal variations in isoprene fluxes (R2=0.52, p<0.05). This study highlights the importance of accounting for differences in isoprene emission capacity across canopy leaf age classes and identifying forest adaptive mechanisms that underlie seasonal variation in isoprene emissions in Amazonia.

Bhimashankar Wildlife Sanctuary (BWS) is located on the crestline of the northern Western Ghats in Pune and Thane districts in Maharashtra State.  It was notified in October 1985 towards conservation of the state animal of Maharashtra, the Giant Squirrel Ratufa indica ssp. elphinstonii.  Although an important protected area in the Western Ghats, due to the lack of a comprehensive report, an assessment of floristic diversity of BWS was done from 2009 to 2016.  The results revealed that forest types and microhabitats are diverse in the sanctuary.  Major forest types are western subtropical broad leaved hill forest to moist deciduous types with a few included small patches of evergreen forests.  The rich flora of the sanctuary is represented by a total of 1,142 angiospermic taxa at species and infraspecific level spread over 619 genera and 124 families.  Of these 1,094 taxa are wild, which belong to 118 families and 586 genera.  Rest of the taxa are planted (34), and 14 introduced.  The taxa are classified as per the APG IV.  The  wild taxa include 20 magnolids, 285 monocots, one Ceratophyllales and 788 eudicots.  Out of these, 217 taxa are Indian endemics; which comprise about 19.84% of the total number of wild taxa (1,094) in the sanctuary and 5.04% of total Indian endemics (4,303).  Total 53 taxa are under different threat categories according to IUCN.  BWS harbours a significant extent of angiosperms in a very small geographic area.

Two new species namely, Cosmocercoides karnatakaensis sp.nov. and Narsingiella clinotarsi sp.nov. from amphibian hosts from Bhadra Wildlife Sanctuary, Western Ghats are described. Cosmocercoides karnatakaensis sp. nov. is characterized by males with small body length, long spicules, small gubernaculum, minute somatic papillae reaching up to esophagus, rosette complex caudal papillae as 8:5:12 pairs and simple caudal papillae as 3:0:0 pairs ; females with small body length, long tail, posteriorly situated vulva and oviparous. Narsingiella clinotarsi sp. nov. is characterized by male having long esophagus, two unequal spicules with trilobed shaft, small gubernaculum and 14 pairs of caudal papillae as 6:1:7 pattern and female having long esophagus, short conical tail and vulva situated at midbody. Both the genera are recorded for the first time from Western Ghats. Key to the species of Cosmocercoides is provided.

Three new species of Protosticta Selys, 1885 (Odonata: Zygoptera: Platystictidae) from the Western Ghats biodiversity hotspot in India: P. cyanofemora sp. nov. (wet evergreen forests in Shendurney Wildlife Sanctuary, Kollam, Kerala and Kalakkad Mundanthurai Tiger Reserve, Tirunelveli, Tamil Nadu), P. myristicaensis sp. nov. (Myristica swamp at Kathalekan, Shivamogga, Karnataka) and P. sholai sp. nov. (montane sholas of Upper Manalar, Meghamalai Wildlife Sanctuary, Theni, Tamil Nadu) are described and illustrated. We compare these three new species with other Protosticta spp. from the Western Ghats based on new material and provide comprehensive differential diagnoses with determination key for males of all species occurring in the Western Ghats. The taxonomic validity of P. mortoni Fraser, 1922 is established with fresh specimens from Hassan, Karnataka, and rediscovery of P. rufostigma Kimmins, 1958 is reported from Kanyakumari Wildlife Sanctuary, Tamil Nadu.
