Despite recent efforts to make large-scale biodiversity datasets available, several data shortfalls still exist that preclude our progress in achieving global conservation and sustainability goals. In this study, we present a comprehensive native tree dataset (1689 species) from the Indian Himalayan Region (IHR)—home to two global biodiversity hots...

Globally, treelines form a transition zone between tree‐dominated forest downslope and treeless alpine vegetation upslope. Treelines represent the highest boundary of “tree” life form in high‐elevation mountains and at high latitudes. Recently, treelines have been shifting upslope in response to climate warming, so it has become important to unders...

Globally, rapid climate and land-use changes in alpine environments are posing severe risks to their bountiful biodiversity and ecosystem services. Currently, nature-based solutions are fast-emerging as the preferred approach to address the challenges of environmental sustainability. In alpine environments, cushion plants owing to their unique arch...

In an era of global environmental change, empirical synthesis of biodiversity data across geographic scales and taxonomic groups is urgently required. Recently, with an upsurge in data synthesis, substantial progress has been made in making massive biodiversity data available on a global scale. However, most of these databases lack sufficient geogr...

The recent adoption of Kunming-Montreal Global Biodiversity Framework requires empirical synthesis of biodiversity data spanning across broad biogeographic scales to inform conservation policy and management. Although the availability and access to biodiversity databases have recently improved, yet majority of these databases lack sufficient geogra...

Worldwide, invasive alien species (IAS) cause significant ecological and economic impacts. To meet the Target-6 of the Kunming-Montreal Global Biodiversity Framework that deals with IAS, it is crucial to fill the geographical knowledge gaps in invasion research. Towards this end, making available inventories of IAS from data-deficient regions of th...

Majority of global biodiversity databases lack sufficient coverage from the developing world and thus severely limiting their worldwide applicability. Bridging these knowledge gaps in global databases merits urgent research priority in biodiversity science. Here, we present Trees of India (ToI), Version-I, a comprehensive database assembled from an...

Several species of the regional pool rarely become part of local communities. Such a con- siderable fraction of the species pool which remains absent but have potential to establish is referred to as dark diversity, and has till now remained understudied. In this study, we aimed to estimate the dark diversity, site-specific species pool, community...

Biotic homogenization by invasive alien species is one of the dominant drivers of global environmental change. However, little is known about the patterns of biotic homogenization in global biodiversity hotspots. Here, we fill this knowledge gap by studying the patterns of biotic homogenization and associated geographic and climatic correlates in I...

Treeline ecotones, the transition zone between the upper closed forest limit (timberline) and treeless alpine vegetation, are the most conspicuous features of mountain ecosystems around the world. Understanding the patterns of plant species richness in the treeline ecotones is crucial in accurately assessing and monitoring the treeline shifts and v...

In the current era of the anthropocene, climate change is one of the main determinants of species redistribution and biodiversity loss. Worryingly, the situation is alarming for endemic and medicinally important plant species with a narrow distributional range. Therefore, it is pivotal to inspect the influence of accelerated climate change on medic...

The Himalaya – a global biodiversity hotspot – harbours diverse flora and fauna, but increasingly beset with multiple threats, including biological invasion by invasive alien species. Here, we aimed to investigate the diversity, distribution, and drivers of alien flora in the Indian Himalayan Region (IHR), a region spread across 12 states/union ter...

Experimental evidences in support of climate warming–driven phenological shifts are still scarce, particularly from the developing world. Here, we investigated the effect of experimental warming on flowering phenology of selected woody plants in Kashmir Himalaya. We selected the twigs of four congeneric pairs of temperate woody species (Prunus, Pop...

Globally, the treelines at higher elevations in mountains are reported to be advancing up-slope in response to recent climate warming. However, little is known about the treeline advancement in the Himalaya due to paucity of baseline vegetation data with which to compare, thus making their assessment and monitoring challenging. To fill this knowled...

In an age of anthropocene, shifting plant phenology is one of the most striking biological indicators of global environmental change. Majority of the studies reporting shifts in plant phenology are available from the North America and Europe and largely scarce from the developing world, including the Himalaya; and studies integrating multiple metho...
