An assessment has been made to identify the rare, endemic and threatened species in the Velliangiri hills of Southern Western Ghats, India. During field explorations, two rare species of terrestrial saprophytic orchids were collected. On critical appraisal and authentication of herbarium specimens, they were identified as Aphyllorchis montana Rchb. f. and Epipogium roseum (D. Don) Lindl. The present paper deals with their correct taxonomic identity, distribution and ecological status.

The province of Surigao del Sur is among the areas in the Philippines with limited wildlife studies, especially on lepidopteran fauna. Thus, this study was conducted to evaluate the butterfly congregation and diversity in Gamut and Mat-e, areas which are underexplored for lepidopteran surveys. It also aimed to assess the conservation and ecological status of the species. Sweep netting for a total of 196 person-hours was carried out to document the species. The results revealed a total of 29 species belonging to four families. Among the families, Nymphalidae was the most represented, comprising 48% of the total richness. The species Gandaca harina mindanaensis and Junonia hedonia ida were the most dominant in both sites representing 12% (each) of the total population. Species richness and diversity (H’) were relatively higher in Mat-e (n=22; H’=1.22) than in Gamut (n=15; H’=1.00). The total endemicity was 31%, but higher endemism was observed in Mat-e (36%) compared with Gamut (20%). The noteworthy findings are the listing of the nationally and globally assessed as rare species (Acrophtalmia leto ochine and Jamides celeno), but were locally assessed as common in Mat-e. One recorded butterfly (Atrophaneura semperi aphtonia) was assessed to be a threatened species. Based on the results, the two habitats showed a poor representation of butterfly assemblage, however, these results are highly affected by the limitations of the observation. Thus, it is recommended that an intensive study on butterflies in the area should be considered.

Analysis of vegetation of Goodrical Reserve forests shows that unlogged area harbours 65 arborescent species of 590 individuals /ha. On the other hand in logged area, number of species were 54 out of 579 individuals /ha. Simpson and Shannon Weiner indices of unlogged and logged area were H’- 3.08, CD-0.092 and H’- 3.60, CD-0.032 respectively. This study also shows that high endemism is seen in Goodrical R.F. and species like, Actinodaphne malabarica, Baccaurea courtallensis, Drypetes elata, Cullenia exarillata, Palaquium ellipticum etc. are quite common. Threatened species like, Anacolosa densiflora and Memecylon subramanii are not common in logged area and common in unlogged area. It is quite probable that these species have been extracted extensively during selection felling, till when the selection felling procedure was completely stopped in 1987, and that is why they are absent in logged area.

Eurema nilgiriensis Yata, 1990, the Nilgiri grass yellow, was described from Nilgiris in southern India. There are not many published records of this species since its original description, and it was presumed to be a high-elevation endemic species restricted to its type locality. Based on the external morphology (wing patterns) as well as the male genitalia, the first confirmed records of the species from Agasthyamalais and Kodagu in the southern Western Ghats, is provided here. This report is a significant range extension for the species outside the Nilgiris, its type locality. Ecological data pertaining to this species as well as the field identification key to all known Eurema of Western Ghats are also presented.

Abstract: The Resplendent Shrub Frog, Raorchestes resplendens Biju, Shouche, Dubois, Dutta, & Bossuyt, 2010 is a Critically Endangered species endemic to the Western Ghats and was considered to be restricted to a three-square kilometer patch atop Anamudi summit.  In this study, we report 36 new locations of the species from the Anamalai massif of the southern Western Ghats.  Niche-based prediction modelling suggests that the species is restricted to Anamalai massif.  The call description of this frog is also provided for the first time. The preferred microhabitat of the frog is Chrysopogon grass clumps in the marshy/swampy montane grassland ecosystem. Restricted to a small area with controlled burning management practiced in its habitat, R. resplendens needs immediate attention.

ABSTRACTThe flowering phenology and flower predation of Cullenia exarillata, a canopy tree at Kakachi in the southern Western Ghats, India, was studied from 1991 to 1993 in relation to general phenological patterns at the community level. Flowering was monitored from 30 marked trees and flower predation estimated from fallen flowers in 40, 1 m2 nets placed under the trees. Flowering occurs in the dry season and coincides with the period of fruit scarcity in the forest. Flowering is synchronous in the population and each tree produces a mean of c. 8730 flowers per tree over a period of c. 47 d. Flowers produced little nectar but the edible fleshy sepals compensated for this. Six species of arboreal mammals and seven species of birds ate the flowers. These consumed 57% of the flower crop of which 37% were completely destroyed. Flower predators could be important in flower fertilization. The overabundance of the flower crop and the timing of flowering, may have evolved as a strategy to satiate predators and enable the flowers to be pollinated during the annual period of fruit scarcity in the forest. This in turn makes Cullenia exarillata a possible keystone species in this forest.
