Patterns of reproductive-mode evolution in doi:10.1111/zsc.12121 Old World tree frogs (Anura, Rhacophoridae). —Zoologica Scripta, 00, 000–000. The Old World tree frogs (Anura: Rhacophoridae), with 387 species, display a remarkable diversity of reproductive modes – aquatic breeding, terrestrial gel nesting, terrestrial foam nesting and terrestrial direct development. The evolution of these modes has until now remained poorly studied in the context of recent phylogenies for the clade. Here, we use newly obtained DNA sequences from three nuclear and two mitochondrial gene fragments, together with previously published sequence data, to generate a well-resolved phylogeny from which we determine major patterns of reproductive-mode evolution. We show that basal rhacophorids have fully aquatic eggs and larvae. Bayesian ancestral-state reconstruc- tions suggest that terrestrial gel-encapsulated eggs, with early stages of larval development completed within the egg outside of water, are an intermediate stage in the evolution of ter- restrial direct development and foam nesting. The ancestral forms of almost all currently recognized genera (except the fully aquatic basal forms) have a high likelihood of being ter- restrial gel nesters. Direct development and foam nesting each appear to have evolved at least twice within Rhacophoridae, suggesting that reproductive modes are labile and may arise multiple times independently. -

Morphological Evolution and Modularity of the Caecilian Skull Carla Bardua1,2* , Mark Wilkinson1, David J
Bardua et al. BMC Evolutionary Biology (2019) 19:30 https://doi.org/10.1186/s12862-018-1342-7 RESEARCH ARTICLE Open Access Morphological evolution and modularity of the caecilian skull Carla Bardua1,2* , Mark Wilkinson1, David J. Gower1, Emma Sherratt3 and Anjali Goswami1,2 Abstract Background: Caecilians (Gymnophiona) are the least speciose extant lissamphibian order, yet living forms capture approximately 250 million years of evolution since their earliest divergences. This long history is reflected in the broad range of skull morphologies exhibited by this largely fossorial, but developmentally diverse, clade. However, this diversity of form makes quantification of caecilian cranial morphology challenging, with highly variable presence or absence of many structures. Consequently, few studies have examined morphological evolution across caecilians. This extensive variation also raises the question of degree of conservation of cranial modules (semi-autonomous subsets of highly-integrated traits) within this clade, allowing us to assess the importance of modular organisation in shaping morphological evolution. We used an intensive surface geometric morphometric approach to quantify cranial morphological variation across all 32 extant caecilian genera. We defined 16 cranial regions using 53 landmarks and 687 curve and 729 surface sliding semilandmarks. With these unprecedented high-dimensional data, we analysed cranial shape and modularity across caecilians assessing phylogenetic, allometric and ecological influences on cranial evolution, as well as investigating the relationships among integration, evolutionary rate, and morphological disparity. Results: We found highest support for a ten-module model, with greater integration of the posterior skull. Phylogenetic signal was significant (Kmult =0.87,p < 0.01), but stronger in anterior modules, while allometric influences were also significant (R2 =0.16,p < 0.01), but stronger posteriorly. -

Abstract:The health of the forest vegetation is one of the driving factors and indicator of climate change impacts. Fragmentation of the forests on the other hand brings out the implications of the various stressing factors on the spatial extent of the forests especially the increasing population and industrialization, which has always impacted the forested regions in the form of deforestation for commercial purposes and conversion of forest land for cultivation. Hence there is a demand for spatial assessment and continuous monitoring of the forested regions. With a wide range of advancing technologies, remote sensing methods are increasingly being employed for monitoring a number of remotely measurable properties of different types of vegetation.This study forecasts utilitarian application of remote sensing as a tool to assess the health of the forest regions. Multispectral satellite image derived vegetation indices like broadband Greenness is used as a combined tool to generate a comprehensive health metrics for the forest canopy. Various band ratio exist for above factor depending on the bands available in the selected dataset. The estimated vegetation indices can be used to generate the final health map of forest regions. -
