“…may also influence seed traits and germination progress, which needs further studies. But several studies have demonstrated that temperature and precipitation are the major factors affecting seed traits, plant performance, and distribution (Chamorro et al, 2018;Ramírez-Valiente et al, 2020;Zhou et al, 2020), as reported in the present study. Furthermore, the SEM analysis in this study indicated that the seed traits affected by MAT was stronger than MAP, which in line with previous study based on a worldwide meta-analysis (Moles et al, 2014).…”

Invasive plants may change their seed traits to adapt to the environment and facilitate their performance. Studies on variation in seed traits among populations of an invader along latitudes/longitudes may assist in revealing how invasive plants cope with variable climates. In this study, we collected seeds of 26 populations of the global invasive plant Ambrosia artemisiifolia along ranges spanning 23° latitudes and 20° longitudes that are highly correlated in its invasive range in China. We measured over 20 seed traits, including seed morphology, phytohormone, nutrients, and germination, and investigated how the climate along the latitudes affects those traits. We found that germination time was significantly delayed with increasing latitude and longitude, while the reversed patterns were true for the germination rate. From low to high latitude, seed size, abscisic acid, and fatty acid were increased, likely affecting seed germination. Our analysis further demonstrated that temperature is the dominant driver of the variability in seed traits and germination. Germination rates of larger seeds in cold ranges were lower, while smaller seeds from warm ranges germinated faster, likely indicating adaptive strategies of the invasive plant in seed trait functional ecology. Together, our findings provide new insights into understanding the seed adaptation strategies during the invasion process and the underlying physiological and biochemical mechanisms involved.

Response of Biodiversity, Ecosystems, and Ecosystem Services to Climate Change in China: A Review

2021

Climate change is having a significant impact on the global ecosystem and is likely to become increasingly important as this phenomenon intensifies. Numerous studies in climate change impacts on biodiversity, ecosystems, and ecosystem services in China have been published in recent decades. However, a comprehensive review of the topic is needed to provide an improved understanding of the history and driving mechanisms of environmental changes within the region. Here we review the evidence for changes in climate and the peer-reviewed literature that assesses climate change impacts on biodiversity, ecosystem, and ecosystem services at a China scale. Our main conclusions are as follows. (1) Most of the evidence shows that climate change (the increasing extreme events) is affecting the change of productivity, species interactions, and biological invasions, especially in the agro-pastoral transition zone and fragile ecological area in Northern China. (2) The individuals and populations respond to climate change through changes in behavior, functions, and geographic scope. (3) The impact of climate change on most types of services (provisioning, regulating, supporting, and cultural) in China is mainly negative and brings threats and challenges to human well-being and natural resource management, therefore, requiring costly societal adjustments. In general, although great progress has been made, the management strategies still need to be further improved. Integrating climate change into ecosystem services assessment and natural resource management is still a major challenge. Moving forward, it is necessary to evaluate and research the effectiveness of typical demonstration cases, which will contribute to better scientific management of natural resources in China and the world.

“…Information on the current distribution of alien species in a geographical landscape is important to understand the ecological and environmental interactions shaping the introduction to naturalization continuum and has a broad range of applications regarding the management of naturalized and invasive species [47]. To estimate the geographical distribution of the species across the country, their occurrence records (latitude and longitude) species were extracted from GBIF (accessed on 5 July 2020; https://doi.org/10.15468/dl.7bkqza).…”

Plant invasions pose an unprecedented threat to biodiversity and ecosystems at different spatial scales, especially for a biodiversity-rich developing nation like India. While country-level checklists are considered as the first step for effective management of plant invasions, databases having biological and ecological attributes of these plant species are of paramount importance for facilitating research activities and developing policy interventions concerning alien plant invasion in a country or region. Though checklists with the names and basic details of alien plant species are available for India, a database aggregating attributes relevant to the understanding of the invasion continuum is lacking. We have curated data for 13 variables related to ecology, biogeography, introduction history, socio-economy and environmental niche of 1747 alien vascular plant species from 22 national and global sources to produce the Indian Alien Flora Information (ILORA) version 1.0 database. This paper describes the detailed methodology of curating these data along with the logic behind selecting these variables to be included in the database. The database, first of its kind for the Indian alien flora, will provide easy access to high quality data, offer a ready reference to comprehend the existing scenario of alien plant species in the country and provide opportunities to identify, scrutinize and prioritize the management of these species. The database is dynamic and will be continuously updated with the availability of new data. It has the provision for bidirectional information exchange with the users, which will allow increasing the resolution of the database as well as the expansion of its capacity. All data will be associated with the source information and ILORA will encourage users to refer to the primary sources to give the contributors full credit and acknowledgement. The database is, therefore, envisaged to become a nationwide collaborative platform for a wide spectrum of stakeholders involving the scientific community, citizens, and policymakers. ILORA is freely accessible via an online data repository as well as through a dedicated website (https://ilora2020.wixsite.com/ilora2020).
