Peer Review #2 of "Dominant forest tree species are potentially vulnerable to climate change over large portions of their range even at high latitudes (v0.1)"

Abstract Woody plants have been cultured in vitro since the 1930s. After that time much progress has been made in the culture of tissues, organs, cells, and protoplasts in tree species. Tree biotechnology has been making strides in clonal propagation by organogenesis and somatic embryogenesis. These regeneration studies have paved the way for gene transfer in forest trees. Transgenics from a number of forest tree species carrying a variety of recombinant genes that code for herbicide tolerance, pest resistance, lignin modification, increased woody bio-mass, and flowering control have been produced by Agrobacterium-mediated and biolistic methods, and some of them are undergoing confined field trials. Although relatively stable transgenic clones have been produced by genetic transformation in trees using organogenesis or somatic embryogenesis, there were also unintended unstable genetic events. In order to overcome the problems of randomness of transgene integration and instability reported in Agrobacterium-mediated or biolistically transformed plants, site-specific transgene insertion strategies involving clustered regularly interspaced short palindromic repeats (CRISPR-Cas9) platform offer prospects for precise genome editing in plants. Nevertheless, it is important to monitor phenotypic and genetic stability of clonal material, not just under greenhouse conditions, but also under natural field conditions. Genetically modified poplars have been commercialized in China, and eucalypts and loblolly pine are expected to be released for commercial deployment in USA. Clonal forestry and transgenic forestry have to cope with rapid global climate changes in the future. Climate change is impacting species distributions and is a significant threat to biodiversity. Therefore, it is important to deploy Strategies that will assist the survival and evolution of forest tree species facing rapid climate change. Assisted migration (managed relocation) and biotechnological approaches offer prospects for adaptation of forest trees to climate change.

The Impact

The present study was carried in different geographical regions of Punjab with the aim to evaluate the impact of climate change on the faunal and floral diversity. A multistage random sampling design was followed to select the study area. Species richness, evenness, Simpson index, Shannon-Wiener index, Index of dominance, Similarity and dissimilarity index were calculated. Comparative performance of different species in different locations was studied in term of present and past status. The number of forest tree species in Hoshiarpur, Ludhiana and Bathinda did not show any change in forest tree species and remain same without any change in bio-diversity index. The number of fruit tree species has been increased comparatively in all three localities. The number of bird’s species has been decreased comparatively in all three localities due to change in climatic condition, whereas, incremental changes were recorded in number of individuals of animals, however number of species is remained unchanged. The number of wild species has been decreased comparatively in all three localities. Ecological indices revealed that diversity index, species richness and evenness index were increased in all three localities; however, Index of Dominance was reduced.
