Environmental niche modelling of the Chinese pond mussel invasion in Europe under climate change scenarios

Ecologica Montenegrina, Journal Year: 2024, Volume and Issue: 72, P. 210 - 226

Published: April 19, 2024

In this paper, we modelled the Chinese pond mussel distribution in European subcontinent under recent climatic conditions and two climate change scenarios. Using species records of Sinanodonta woodiana (Bivalvia: Unionidae) Europe a set bioclimatic variables, applied maximum entropy approach provided by MaxEnt to build models investigate how each variable affects distribution. We found that winter temperatures had largest contribution all three scenarios (recent, RCP 4.5, 8.5). minimum training presence threshold, as less stringent, 10th percentile more map potential area occurrence. The show climatically optimal range, depicted stricter will be expanded eastwards At same time, minimally suitable environments, represented stringent contracted future climate. highlight British Isles Azov-Kuban Lowland are most suitable, among uninvaded regions, for further S. invasion.

Identification of microsatellite markers for the invasive freshwater mussel Sinanodonta lauta (E. von Martens, 1877) (Bivalvia: Unionida)

Ecologica Montenegrina, Journal Year: 2024, Volume and Issue: 73, P. 221 - 225

Published: May 29, 2024

The Far Eastern freshwater mussel Sinanodonta lauta has recently been recorded in European Russia outside of its native range. As an invasive species affecting ecosystems, this is still poorly investigated many aspects, including population genetics. In study, we describe for the first time eight microsatellite loci that were developed based on a previously published set markers Chinese Pond Mussel (Sinanodonta woodiana).

Reproduction in the tropical invasive freshwater mussel Sinanodonta pacifica (Unionidae), at different elevations in West Java, Indonesia

Freshwater Biology, Journal Year: 2024, Volume and Issue: 69(8), P. 1144 - 1156

Published: July 6, 2024

Abstract Following the unintentional introduction of freshwater mussel Sinanodonta pacifica into Indonesia, it dispersed rapidly. The life cycle and reproductive characteristics this species throughout Indonesia are poorly known. This information is required to manage mitigate against any negative effects that might have on native ecosystems. We firstly report biology S. by combined temporal monitoring, histological investigation, light scanning electron microscopy, relate densities, their embryological stages, environmental variables at five sites in West Java from 67 1,580 m above sea level. protandrous can spawn eggs brood larvae year, with spawning peaks early rainy season September December. Mussels midland 4.1–8.9‐fold more glochidia than those lowland or highland sites; produce 3.1–4.3‐fold hermaphrodites sites. High levels suspended solids low chlorophyll‐a concentrations contribute a higher proportion decrease production.

Dead or alive: the effect of shells and living individuals of Sinanodonta woodiana (Lea, 1834) on habitat selection and behaviour of European unionid bivalves

NeoBiota, Journal Year: 2024, Volume and Issue: 94, P. 243 - 259

Published: Aug. 7, 2024

1. Ecosystem engineering freshwater bivalves, burrowing in the substratum and accumulating shell deposits, transform bottom habitats. Especially invasive Asian bivalve Sinanodonta woodiana (SW), due to its rapid growth, large size, high fecundity, can affect benthic communities. Here, we determined effect on habitat selection behaviour of endangered native Anodonta cygnea Unio tumidus . 2. We conducted laboratory preference assays (Experiment 1: choice between two substrata) exposing bivalves pure sand (control), shells (several densities surface or burrowed), living SW. Then, tested their locomotion 2) substrata contaminated with 3.

A new invasive freshwater mussel: Discovery of a non-native population of Pilsbryoconcha exilis (Lea, 1838) in Myanmar (Bivalvia: Unionidae)

Ecologica Montenegrina, Journal Year: 2024, Volume and Issue: 78, P. 107 - 118

Published: Sept. 23, 2024

The present study reports on the first record of a non-native population freshwater mussel Pilsbryoconcha exilis (Lea, 1838) (Bivalvia: Unionidae) in Myanmar. It was discovered from irrigation canals that are situated Delta Region Ayeyarwady River. Based approximate age estimates and information local villagers, this probably established 2019-2020. DNA sequence data reveals shares single COI haplotype previously recorded Udon Thani Province Thailand (Mekong River drainage). evidence, we could assume P. introduced to Myanmar Thailand.

Native to Eastern Asia, the Chinese Pond Mussel (Sinanodonta woodiana) (Mollusca: Bivalvia) is one of most threatening invaders freshwater habitats worldwide. Algerian waters are no exception. In 2023, mussel was discovered in two locations, which a protected area. Here, we report Babar Dam reservoir as new site its occurrence and southernmost record species country. The present survey conducted May 2023 included set live S. woodiana specimens variable sizes (from 95.4 210.4 mm) developmental stages 4 11 years old), suggests that succeeded establishing sustainable population can spread colonise territories. possible pathway introduction whole country discussed.
