Impact of Spartina alterniflora Invasion in Coastal Wetlands of China: Boon or Bane?

Biology, Journal Year: 2023, Volume and Issue: 12(8), P. 1057 - 1057

Published: July 27, 2023

Invasive plants, like Spartina alterniflora (SA), have a competitive advantage over native flora due to their rapid utilization of vital soil nutrients. This results in the depletion resources for plant species, significantly impacting ecosystem diversity and stability. comprehensive review addresses several key aspects related SA’s spread spatial distribution China’s wetlands. The expansion is attributed its high reproductive ability, adaptability environmental factors elevated salinity, ability disperse seeds via tides. mainly were found Zhejiang, Jiangsu, Fujian, Shanghai provinces, accounting more than 90% total area. growth displacement species loss microbial, plant, animal diversity.

Increasing risk of invasions by organisms on marine debris in the Southeast coast of India

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 195, P. 115469 - 115469

Published: Sept. 12, 2023

Increasing amount of anthropogenic litter in the marine environment has provided an enormous number substrates for a wide range organisms, thus serving as potential vector transport fouling organisms. Here, we examined organisms on different types stranded (plastic, glass, rubber, foam sponge, cloth, metal and wood) eight beaches along southeast coast India. In total, 17 encrusting species belonging to seven phyla (Arthropoda, Bryozoa, Mollusca, Annelida, Cnidaria, Chlorophyta Foraminifera) were identified 367 items, with one invasive species, mussel Mytella strigata, detected. The most common associated cosmopolitan bryozoans Jellyella tuberculata (%O = 31.64 %) J. eburnea (28.61 %), barnacle Lepas anserifera (29.97 Amphibalanus amphitrite (22.34 sp.

Ecological impacts of invasive ecosystem engineers: A global perspective across terrestrial and aquatic systems

Functional Ecology, Journal Year: 2023, Volume and Issue: 38(1), P. 37 - 51

Abstract In both terrestrial and aquatic ecosystems, invasive species are a major driver of global change that is increasing in scope impact due to the increase trade, habitat modification climate change. Among species, those known as ‘ecosystem engineers’ considered specific, highly influential, type invaders, where an invader significantly alters new environment, either physically or chemically. this context, perspective review discusses different types possible impacts ecosystems engineers (IEE) terrestrial, freshwater, marine ecosystems. Scanning relevant literature on topic, we find 12‐year lag use terms concept ecosystem invasion‐related publications since first publication 1994, with steep between 2006 2014.

Effects of biodiversity on functional stability of freshwater wetlands: a systematic review

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: April 8, 2024

Freshwater wetlands are the wetland ecosystems surrounded by freshwater, which at interface of terrestrial and freshwater ecosystems, rich in ecological composition function. Biodiversity plays a key role maintaining stability their habitat functions. Due to anthropogenic interference global change, biodiversity decreases, turn destroys function leads serious degradation wetlands. An in-depth understanding effects on its regulation is crucial for conservation. Therefore, this paper reviews environmental drivers wetlands, explores plant diversity microbial stability, reveals impacts mechanisms changes biodiversity, further proposes an outlook research. This provides important reference conservation enhancement.
