We contend that the exclusive focus on English language in scientific research might hinder effective communication between scientists and practitioners or policy makers whose mother tongue is non-English. This barrier knowledge data transfer likely leads to significant gaps may create biases when providing global patterns many fields of science. To demonstrate this, we compiled economic costs invasive alien species reported 15 non-English languages. compared it with equivalent from...
Invasive species have caused severe impacts on biodiversity and human society. Although the estimation of environmental by invasive has increased in recent years, economic losses associated with biological invasions are only sporadically estimated space time. In this study, we synthesized incurred Asia, based most comprehensive database costs worldwide, including 560 cost records for 88 22 countries. We also assessed differences across taxonomic groups, geographical regions impacted sectors,...
In recent years there have been attempts to relate the distribution of rainfall Indian southwest monsoon with antecedent upper air factors near scene activity for purpose long range forecasting" Several arc critically examined in this context make a judicious selection. It is found that total over country significantly correlated latitudinal position sub-tropical ridge on mean circulation chart April at 500 mb level. A regression equation developed sample data period 21 (1950-1970). On...
Ecological niche models (ENM), an effective tool to predict the potential distribution of invasive species, are often built on assumptions conservatism between native and ranges genetic uniformity population. In this study, we have incorporated information with ENM generate projected species Mikania micrantha for which two clusters were identified in South Southeast Asia. Climatic niches compared ranges, as well lineages by using multivariate univariate analyses. MaxEnt, occurrence data...
Phenotypic variation in the introduced range of an invasive species can be modified by genetic variation, environmental conditions and their interaction, as well stochastic events like drift. Recent studies found that epigenetic modifications may also contribute to phenotypic being independent changes. Despite gaining profound ecological insights from empirical studies, understanding relative contributions these molecular mechanisms behind has received little attention for plant particular....
Similarity of climatic niches occupied by a species in its native and invasive ranges has been recognized as one the key factors for successful invasion. Accounting changes niche over time may provide better understanding dynamic biological invasion process. We investigated these an alien plant Mikania micrantha South Southeast Asia, Australia, Oceania parts USA. Based on documented occurrences 200 years (1800-2017), we reconstructed introduction history estimated dynamics presumed routes....
The impacts of invasive alien species are well-known and categorised as a leading contributor to biodiversity loss globally. However, relatively little is known about the monetary costs incurred from invasions on national economies, hampering management responses. In this study, we used published data describe economic cost in Southeast Asia, with focus Singapore – biodiversity-rich, tropical island city state small size, high human density trade volume, three factors likely increase...
Abstract Phylogeographic forces driving evolution of sea‐dispersed plants are often influenced by regional and species characteristics, although not yet deciphered at a large spatial scale for many taxa like the mangrove Heritiera littoralis . This study aimed to assess geographic distribution genetic variation this widespread in Indo‐West Pacific region identify phylogeographic factors influencing its present‐day distribution. Analysis five chloroplast DNA fragments’ sequences from 37...
In this review paper general climatological features of rainfall including rainy days maximum and minimum, temperatures, annual evaporation, droughts floods, thunderstorms, hailstorms duststorrns, the water balance aspects, namely, surplus deficit, over arid semi-arid regions country have been discussed. A has also made studies on climatic fluctuations area. It observed that elements do not exhibit presence any regular Pattern. was therefore, concluded there is no reason to believe Rajasthan...
The mahogany family, Meliaceae, contains 58 genera with only one mangrove genus: Xylocarpus . Two of the three species genus are true mangroves ( X. granatum and moluccensis ), is a non-mangrove rumphii ). In order to resolve phylogenetic relationship between species, we sequenced chloroplast genomes these along two Meliaceae family Carapa guianensis Swietenia macrophylla ) compared genome features variations across five species. shared 130 genes (85 protein-coding genes, 37 tRNA, eight...
The successful establishment of an invasive plant in a novel environment has been attributed to the phenotypic plasticity traits, with most studies focussing on vegetative trait either experimental and/or natural habitat conditions. This study explores role plasticity, both and reproductive Mikania micrantha growing as ground cover diverse urban areas city Kolkata, India. Quadrat based soil sampling was conducted three types, namely roadsides, abandoned plots, from four regions within city....
Phylogenetic relatedness is one of the important factors in community assembly process. Here, we aimed to understand large-scale phylogenetic relationship between alien plant species at different stages invasion process and how these relationships change response environmental filtering multiple spatial scales extents.We identified three stages, namely invasive, naturalized, introduced, China. The occurrence records were used quantify two abundance-based metrics [the net index (NRI) nearest...
Intraspecific trait variability, which plays an important role in community assembly, was studied invasive plant Mikania micrantha along with its impact on composition. The abundance of M. and composition were recorded a quadrat-based study conducted spatial (littoral, terrestrial, intermediate habitat) temporal (summer, monsoon, winter) scale. Soil parameters analyzed some fitness-related traits estimated. Season habitat had significant effects abundance. Seasonal plasticity evident...
Introduction and spread of the halophyte Spartina alterniflora is one largest continental-scale biological invasion events in Asia Americas. Rapid globalization broad environmental tolerance species increase chance novel invasions. Thus, we aimed to identify susceptible regions inform prevention control activities. A comprehensive global occurrence dataset corresponding bioclimatic variables were used characterize species' climatic niche predict current future potential distributions....
