Quantifying beryllium concentrations in plant shoots from forest ecosystems using cation‐exchange chromatography and quadrupole ICP‐MS

open access: yesAnalytical Science Advances, 2020
Beryllium (Be) is known to be one of the most toxic elements but at the same time exerts a stimulating effect on plant growth. Despite this contradiction, little is known about the Be metabolism in living organisms, partially because of the low amounts ...

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

open access: yes, 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

Resilience of riparian spiders to floods: evidence from a mesocosm study

open access: yesInsect Conservation and Diversity, EarlyView.
Mesocosm experiment to assess the impact of flood duration on flood‐naïve riparian spider communities. In May, spider richness decreased with flood duration, while in June, flood duration increased abundance, richness and promoted wetland specialists. Flood‐naïve riparian spiders unexpectedly appear highly resilient to flooding.

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

open access: yesAnnals 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.

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

open access: yesInsect 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

open access: yesInsect 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]

open access: yesGeo 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

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

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

open access: yesTaxonomy
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
