Accumulation and Distribution of Heavy Metals in Green-Lipped Mussel Perna Viridis (Linnaeus) from the West Coast of Peninsular Malaysia [PDF]

, 1999
The main aim of this study is to establish mussel Perna viridis as a biomonitoring agent along the west coast of Peninsular Malaysia. In this study, the levels of heavy metals had been studied in the mussel P.

Hydrobia ulvae imposex levels at Ria de Aveiro (NW Portugal) between 1998 and 2007: a counter-current bioindicator? [PDF]

, 2010
Imposex expression in prosobranch gastropods has been widely used as a biomarker of tributyltin (TBT) pollution. Estuaries have been described as the most affected areas by this problem since they usually enclose the main TBT sources—ports, dockyards ...

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Acetylcholinesterase Activity in Nile Tilapia (Oreochromis niloticus Linn.) Following Exposure to Carbamate Insecticide

Annals of Tropical Research, 2018
Acetylcholinesterase (AChE) activities were determined as affected by exposure to sublethal doses of fenobucarb (BPMC) on Nile tilapia. Fish were exposed for different periods, namely: 0, 7, 14, 21, and 28 days.

The use of the moss, Calymperes Delessertii besch., as a bioindicator to airborne heavy metals [PDF]

, 1985
A detailed study on the accumulation of aerial heavy metals by the moss, Calymperes delessertii Besch. was conducted. Heavy metals studied were Zn, Cd, Ni, Fe, Mn, Pb and Cu. The suitability of the moss as a bioindicatoT to these aerial metals was also

Seasonal dynamics in terrestrial insect communities after the impact of the Brumadinho tailings dam disaster

Insect Conservation and Diversity, EarlyView.
Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Distribution Characteristics of Limpets Inhabiting the Rocky Intertidal Zone of the Western and Southern Coast of South Korea [PDF]

Geo Data
As a primary grazer in intertidal ecosystems, limpets play a key role in regulating algal cover and maintaining community structure. Therefore, the distribution and species composition of limpets can serve as effective biological indicators to assess the

Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

Insect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.

Diatom Flora from Time-Series Sediment Trap in the Kuroshio Extension Region of the Northwestern Pacific

Taxonomy
Precise identification of diatom species is fundamental to correctly interpreting their roles in the marine ecosystems; the documentation of species records with illustrations is therefore essential to guarantee ecological works and the continuous use of
