“…The habitat in the Palani Hills chiefly constitutes moist deciduous and southern tropical wet evergreen forests (B. Balaguru et al 2016). These habitats are at an altitude of 1600-2000 m asl and receive an average annual rainfall of 1500 mm (Bhupathy et al 2009).…”

The monotypic genus Dravidogecko, represented by its type-species D. anamallensis, is singular amongst peninsular Indian gekkonid lineages in its endemism to the Western Ghats. Molecular species delimitation approaches reveal at least seven species-level lineages within the genus from its distribution range across the mid–high elevations of the southern Western Ghats of India. These lineages, albeit superficially cryptic, are patently diagnosable from each other by employing a limited but precise set of morphological characters. Six of these lineages that were obscured under the nomen D. anamallensis are herein recognized as distinct species. A reappraisal of the genus Dravidogecko is provided based on external morphology and osteological characters, along with a detailed redescription of the holotype of D. anamallensis. A key to the species based on diagnostic characters is presented. Gene-trees based on mitochondrial and nuclear DNA data recovered marginally disparate topologies and were consequently coalesced into a species-tree for phylogenetic inference. Timetree analysis reveals late Miocene cladogenesis in this group and establishes late Palaeocene divergence from its sister genus, Hemidactylus, making Dravidogecko one of the earliest, extant lizard lineages to have colonized peninsular India.

“…This leads to altered ecological processes, changes in species composition, and reduced functional diversity (McConkey and O'Farrill, 2016;Bovo et al, 2018). Human activities are isolating and decreasing the sizes and quality of forest habitats creating disturbance zones that are associated with increased invasion rates (Gosper et al, 2005;Balaguru et al, 2016). Biological invasions disturb ecosystem functioning and are associated with negative socio-economic impacts (Liebhold et al, 1995), and as such are a major threat to biodiversity (Wilson et al, 2013;Blackburn et al, 2019) and human livelihoods (Wilson et al, 2013).…”

“…Trait-based approaches to seed dispersal studies are lacking and highlight the importance of filling these gaps (Garcia et al, 2016). A predictive approach is important for conservation planning, prioritising forest invasion management (Balaguru et al, 2016) and reducing uncertainty in management (da Silveria Ponte et al, 2015).…”

Functional traits vary among fleshy-fruited invasive plant species and their potential avian dispersers

Habitat fragmentation has a multitude of negative effects on biodiversity, including the facilitation of alien plant invasion. Of concern in South Africa is the spread of fleshy-fruited invasive plant species, which in many places are replacing indigenous vegetation in frequently disturbed and fragmented habitats. The availability of dispersers is among the most important factors for the successful invasion of fleshy fruited invasive plant species. Dispersers differ in their dispersal capacity, and the success of frugivore dispersed plants depends both on animal and plant traits. Here, we used the functional traits of fleshy-fruited invasive plants to test for specific associations with avian functional traits in Indian Ocean Coastal Belt Forests, KwaZulu-Natal Province, South Africa. We predicted that fleshy-fruited invasive plant species that were more likely to persist in disturbed Indian Ocean Coastal Belt Forests were small-seeded, open habitat species with longer fruiting period lengths. The use of multivariate analyses showed that avian seed dispersers and fleshy-fruited invasive plant species differed in the functional traits between species with each group (i.e. plants and avian dispersers) that were important for seed dispersal. For fleshy-fruited plants, morphological traits (seed size, fruit size) and phenological traits (fruiting period length) were more variable between the species. For avian species, the variation was in their morphology (body size, gape width, bill length), abundance and habitat specificity. As predicted, avian species that were potentially dispersing invasive plants were forest generalist and relatively abundant species persisting in the fragmented forest. Fleshy-fruited invasive plant species that were predicted to be effectively dispersed were small-seed, open habitat species with longer fruiting length including lantana (Lantana camara), white mulberry (Morus alba), Brazilian pepper (Schinus terebinthifolius) and bugweed (Solanum mauritianum). Overall, our study showed that easily measured traits were important for understanding forest invasion dynamics and give insights to management strategies that can be developed to minimise further infestations.

The composition of soil-seed bank reflects the condition of vegetation in the past and could be used for predicting the composition of plants that will grow in the future. This study aims to determine the amount and composition of soil-seed bank in Bekol savanna, Baluran National Park. Soil samples were taken using a combination method of quadrat-transect on the invaded and not invaded areas by Acacia nilotica. Soil samples were extracted using wet-sieving method. After the extraction process, the seeds were identified and calculated using a stereo microscope. The result showed that soil-seed bank density was lower at the invaded location (7,566.88 seeds/m3) as compared to the uninvaded location (16,798.3 seeds/m3). The soil-seed bank was found in the invaded site comprising 12 species of broadleaved weeds and 5 species of grasses from 7 families, whereas those in the uninvaded area consisted of 10 species of broadleaved weeds and 7 species of grass from 8 families. This study showed that the invasion of A. nilotica significantly affected the amount and composition of soil-seed bank in various soil depths of Bekol savanna.
