Historically, studies aimed at prospecting and analyzing paleontological and neontological data to investigate species distribution have developed separately. Research at the interface between paleontology and biogeography has shown a unidirectional bias, mostly focusing on how paleontological information can aid biogeography to understand species distribution through time. However, the modern ...
The vulnerability of alpine environments to climate change presses an urgent need accurately model and understand these ecosystems. Popularity in the use digital elevation models (DEMs) derive proxy environmental variables has increased over past decade, particularly as DEMs are relatively cheaply acquired at very high resolutions (VHR; <1 m spatial resolution). Here, we implement a multisca...
Blyth’s Swift, endemic to the Indian subcontinent, is one of four taxa Pacific Swift Apus pacificus complex. It known breed in high altitudes (>2,000 m) and disperse widely winters, as far southern extremity Nilgiri Region Western Ghats India. However, true extent its non-breeding range remains uncertain. The present study reports extended breeding species also an attempt confirm using Speci...
In the modern world, when problems of environment are most acutely associated with climate change, amphibians considered to be vulnerable group anamniotes as an indicator state wetlands. Along a decrease numbers among in Europe, nowadays newts especially suffer from impact invasive species, particular predators such Chinese sleeper, Perccottus glenii. This predatory fish species has recently sp...
Current applications of species distribution models (SDM) are typically static, in that they are based on correlations between where a species has been observed (ignoring the date of the observation) and environmental features, such as long-term climate means, that are assumed to be constant for each site. Because of this SDMs do not account for temporal variation in the distribution of suitabl...
Vertebrate sex-determining mechanisms (SDMs) are triggered by the genotype (GSD), by temperature (TSD), or occasionally, by both. The causes and consequences of SDM diversity remain enigmatic. Theory predicts SDM effects on species diversification, and life-span effects on SDM evolutionary turnover. Yet, evidence is conflicting in clades with labile SDMs, such as reptiles. Here, we investigate ...
The concepts of spatial-division multiplexing (SDM) technology were first proposed in the telecommunications industry as an indispensable solution to reduce the cost-per-bit of optical fiber transmission. Recently, such spatial channels and modes have been applied in optical sensing applications where the returned echo is analyzed for the collection of essential environmental information. The k...
There is increasing evidence that the global distributions of a large number of species are shifting with global climate change as they track changing surface temperatures that define their thermal niche. Modelling efforts to predict species distributions under future climates have increased with concern about the overall impact of these distribution shifts on species ecology, and especially wh...
Current disjunct patterns can result from long-distance dispersal or postglacial contraction. We herein investigate the evolutionary history of Triplostegia to elucidate the disjunction between the Himalaya-Hengduan Mountain region (HHM) and Taiwan (TW). Genetic structure of Triplostegia was investigated for 48 populations using sequences from five chloroplast loci and the ribosomal nuclear int...
Invasion dynamics are context-dependent and non-equilibrial, with invasive spread associated impacts continuously unfolding contingent on pathway, history, chance, over features of recipient ecosystems. Identifying a tool that can predict the risk extent an invasion, help stakeholders make informed decisions, is highly sought after. The Species Distribution Model (SDM) powerful statistical mach...
