Summary: Man-made pollution, including microplastics, are threatening the world's oceans. Sponges have been identified as potential bioindicators for microparticulate pollutants, with samples from coral reef demosponges near Bangka Island in Indonesia showing accumulation of a variety of particles including polystyrene, cotton, titanium dioxide and blue-pigmented particles. Sponges can incorporate thousands of microparticulate pollutants in their tissue, making them a strong candidate for biomonitoring efforts.

Summary: Concentrations of heavy metals and trace elements in marine environments have become a growing problem, affecting intertidal ecosystems. The study found that a water treatment plant near the coast may be causing increased coverage and mortality of the cirriped Chthamalus stellatus, as well as higher metal concentrations in water samples. Therefore, the survival rates of C. stellatus could be used as bioindicators for metal pollution.

Summary: This study examines the relationship between microplastics and eastern oysters in Long Island Sound. The results show low concentrations of microplastics in oysters and their surrounding environment, with no clear correlation. This suggests that oysters are not a reliable bioindicator species for microplastic pollution.

Summary: Environmental disturbances from anthropogenic energy pollution are a growing concern for the marine environment. This study evaluated the effects of different electric current densities on a benthic foraminiferal species used as pollution indicators. The results suggest that the selected species may tolerate pulsed currents better than constant ones, providing important insights for defining appropriate electrical density thresholds.

Summary: Legacy mines have caused contamination in the environment, particularly from waste rock, slag, and tailings, which introduce high concentrations of metals to soil and sediments. Ants were investigated as potential indicators of metal pollution in areas rich in copper, zinc, arsenic, silver, and lead. Results showed that manganese and copper concentrations in ants were similar between mine and reference samples, while zinc concentrations differed significantly. Ants from reference areas accumulated more metals in their bodies compared to ants from the mine, with different body parts showing different metal accumulation patterns. Some genera of ants were found to be more suitable as indicators of metal pollution than others.

Summary: There is a lack of existing data on trace elements of benthic sea organisms. However, due to environmental contamination concerns, the use of organisms as biomonitors has increased. This study analyzed metal concentrations in sediment and sponge species using ICP-MS. The results showed significant differences in metal concentrations between benthic sediments and sponge species, indicating that different sponge species have varying abilities to accumulate specific metals. Negombata magnifica and Phorbas species were identified as indicators or accumulators of copper and manganese, while Callyspongia species was found to be an indicator or accumulator of copper only. The concentrations of copper and arsenic in the sediment were found to be above the Effects Range Low threshold, highlighting the need for further attention to these metals. This research provides a valuable dataset for monitoring strategies in this ecosystem and the use of sponge species for biomonitoring.

Summary: This study investigated the concentrations of microparticles in different spatial scales in the Salish Sea and found the presence of plastic contamination. Slight differences in concentrations and morphotypes of microparticles were observed at a regional scale, while no significant differences were found at a localized scale. Synthetic materials, including polymer plastics, accounted for a subset of the particles.

Summary: The study evaluated the rhizogenic capacity of yerba mate mini-cuttings from different genotypes and found that while the anatomical features and root development were similar, there were significant differences in rooting performance and related growth characteristics. Despite variations in biochemical features such as POD, PPO, and PC activities/content, these did not directly impact the overall rooting performance of the mini-cuttings.

Summary: Glyphosate-based herbicides not only promote plant death by inhibiting the EPSPS enzyme, but also through biochemical, physiological, and structural changes. These changes can serve as biomarkers of Glyphosate-based herbicide sensitivity, aiding in future research monitoring the presence of these herbicides in plant communities near agricultural areas.

Summary: This study investigated the variation in foliar anatomical traits of epiphytes along vertical stratification. Different species from varied groups showed a variation in foliar characters that reflected the variation found in microclimatic parameters along phorophyte strata. The thickness of mesophyll was influenced by height differences and light intensity along phorophytes.

Summary: This study aimed to test the impact of different leaf traits on particle retention in two legume species. By conducting a bio-monitoring study in southeastern Brazil, it was found that leaf roughness, leaf wettability, epidermal-cell undulation, epidermal-cell perimeter, and epicuticular wax morphology and composition played important roles in particle retention.

Summary: This study investigated the reasons for Brachiaria decumbens becoming the main grass in pasturelands affected by mining tailings in Mariana, Brazil. It also examined the ecophysiological effects of mining tailings on B. decumbens and tested the potential of mixing the tailings with unaffected local soil to improve the affected soil properties. The results showed that the tailings compromised the normal ecophysiological state of B. decumbens, but the species was able to survive by efficiently acquiring essential elements. The soil management tested in this study could mitigate the stress caused by the tailings and serve as an alternative for environmental recovery.

Summary: The search for sustainable technologies to increase yield in modern agriculture is crucial. Polymers of biological origin, such as polysaccharides, have been investigated for their potential use in agriculture. The association of copper and magnesium with polysaccharides was found to promote plant growth and yield, improve enzyme concentration, and reduce the severity of powdery mildew in tomato leaves.

It is similar to the critically endangered species Syagrus cabraliensis, but they can be distinguished by morphoanatomical characters. The findings emphasize the importance of the Serra do Cabral massif as a home for endemic and rare palm species.

Summary: Canga is a harsh environment with high biodiversity and endemism, but it is threatened by human activities. The Serra do Cabral mountain in Minas Gerais, Brazil, is the habitat of a micro-endemic species called canga-Syagrus graminifolia subsp. cabraliensis. This species has unique features and is affected by fires and road traffic. The absence of other populations in nearby areas is explained by predation of its seeds by beetle larvae. Due to geographical isolation and morpho-anatomical novelties, this taxon is proposed as a new species called Syagrus cabraliensis. Given the risk of extinction, it is urgent to include the population area of S. cabraliensis in Serra do Cabral State Park and divert the road.
