Abstract. The Western Ghats of India is a UNESCO World Heritage Site and is one of the eight “hotspots” of biological diversity in the world. It is also referred to as the “Great Escarpment of India”. This paper provides information on the diversity of freshwater fish fauna of six river systems of the southern Western Ghats. The study area has been identified geographically using a GPS, and the respective topographic map has been digitized using ArcGIS software. The fish fauna were collected from various streams and rivers using cast nets, dip nets, gill nets and drag nets. Among the 31 georeferenced sites sampled from the rivers of the southern Western Ghats, a total of 64 species, belonging to 6 orders, 14 families and 31 genera, were recorded. Among them, the order Cypriniformes was dominant, with 3 families, 18 genera and 49 species (76.6 %). Principal component analysis and cluster analysis were performed to express the contribution of the variables and their influence on the species diversity. Interestingly, of the 31 sites, Thunakadavu stream, Gulithuraipatti, Athirapally, Naduthotam, Nadathittu, Mullaithodu, Thonanthikla, Noolpuzha and Sinnaru exhibited high variation in species diversity. Nearly 15 species were found to be threatened in the Western Ghats. Garra periyarensis and Cirrhinus cirrhosus are known to be vulnerable and Hemibagrus punctatus is critically endangered because of various anthropogenic activities. The study clearly indicates that certain timely measures have to be taken immediately to protect the fish fauna in the southern Western Ghats (https://doi.org/10.1594/PANGAEA.882214).

Abstract. We studied the freshwater fish fauna of Rivers of Southern Western Ghats for a period of three years from 2010 to 2013. We recorded 64 species belonging to 6 orders, 14 families and 31 genera. Alteration in the micro and macro habitats in the system severely affects the aquatic life especially fishes and also complicates the fish taxonomy. In the present study a total of 31 sites of six river systems of Southern Western Ghats were studied in which a total of 64 species belonging to 6 orders, 14 families and 31 genera were recorded. Among the 64 species Cyprinidae was the dominant family with 3 family 18 genus and 49 species (76.6 %) compared to other order and families, further the data analyses suggested that species belonging to the order Cypriniformes were found to be the dominant species in the locations considered in the present survey. Interestingly, among the 31 sites Thunakadavu stream, Gulithuraipatti, Athirappalli, Naduthotam, Nadathittu, Mullaithodu, Thonanthikla, Noolpuzha and Sinnaru exhibited high variations in species abundance and as well species richness. Fifteen out of the 64 fish species endangered to the Western Ghats. Garra periyarensis and Cirrhinus cirrhosus are known to be vulnerable and Hemibagrus punctatus is Critically Endangered because of various anthropogenic activities. The significances of the study and timely measures needed to protect the species have also been concisely discussed. https://doi.org/10.1594/PANGAEA.882214

The freshwater fish fauna of Hiranyakeshi River, a tributary of the Krishna River System, originating in the Western Ghats of Maharashtra, was studied for a period of three years from 2013–2016.  We reported 57 species belonging to seven orders, 17 families and 42 genera.  Cypriniformes was the most species rich order followed by Siluriformes, while Cyprinidae was the most predominant family.  At least 21 freshwater fish species found in Hiranyakeshi River are endemic to river systems originating from the Western Ghats, while nine species are endemic to the Krishna River system.  The true diversity of freshwater fishes in this region, however, is still obscure because of lack of detailed taxonomic studies in this region.  Of the total species, at least 11 are in the threatened and near threatened categories of the IUCN Red List and Hiranyakeshi River holds a good population of most of these species.  The fish fauna in this region, however, is threatened by several stressors including invasive fishing practices, water impediment due to upcoming dams, invasive introduced species and water pollution due to agricultural runoffs and industrial effluents.

Freshwater fish fauna of Nandur-Madhmeshwar wetland was studied during the period 2010–2012.  A total of 39 species of freshwater fish belonging to 14 families and 30 genera were recorded.  Out of the 39 species, 21 species are reported for the first time from this wetland, which includes Mystus malabaricus, an endemic species of the Western Ghats.  The fish fauna of the wetland is threatened due to invasive alien species as well as anthropogenic activities such as overfishing, sand mining, siltation, and organic and inorganic pollution.  As a result, urgent implementations of stringent conservation measures are essential.

The Western Ghats

The Western Ghats of India support an array of tropical forests ranging from wet evergreen to scrub formations.  Several endemic and threatened plant species are located in areas other than protected areas (PAs).  There is an urgent need to understand species diversity in areas other than PAs, for effective management of tropical forests.  In this context, reserve forests and informal PAs of Amboli from northern Western Ghats have been investigated. Woody species composition, diversity, and stand structure were assessed by laying quadrats and transects (n=46, area=2.575ha) in closed and open canopy forest patches covering habitat heterogeneity and environmental gradient of the area. A total of 2,224 individuals (of 87 species, 68 genera, and 35 families) was enumerated.  Memecylon umbellatum, Syzygium cumini, and Diospyros nigrescens were found to be the most dominant species as per importance value index.  Melastomataceae was the most dominant family as per family importance value, whereas Euphorbiaceae and Rutaceae were the most speciose.  Fourteen IUCN Red List assessed species and 18 species endemic to the Western Ghats were encountered.  Endemic species accounted for nearly 20% of the total number of individuals sampled.  Demographic profile exhibited reverse ‘J’ pattern.  Average basal area was 27.02m2 per hectare. Woody species diversity of Amboli forests was found comparable with other PAs from northern Western Ghats.  Amboli and the adjoining area have been proposed as ecologically sensitive and in the wake of anthropogenic and developmental pressures they experience, it calls for urgent conservation attention.

Distribution of butterfly species along the latitudinal and habitat gradients of the Western Ghats was studied. The Western Ghats was divided into 14 latitude zones and the species diversity in each latitude zone, along with habitats of their occurrence, were studied using the data from literature survey for the entire Western Ghats as well as data from personal observations in the areas between 14°N to 20°N latitudes. Out of 334 species recorded from the Western Ghats, 58 species were found in all latitudinal zones, while 5 species were reported in only one latitudinal zone. Further, southern Western Ghats consisted of more number of species and more number of genera as compared to northern Western Ghats. Latitudinal zones between 10°N to 12°N had most of the Western Ghats endemic species. Habitat wise distribution of species revealed three significant clusters grossly separated by the level of human disturbance. Evergreen forest habitats supported maximum number of species endemic to the Western Ghats.
