Cambridge Prisms: PlasticsThe present study aimed to elucidate the extent of microplastic (MP) contamination in the Guandu River basin. Samples were collected from surface waters using a Manta trawl at 11 sites in two seasonal periods. MPs abundance was 6.1 ± 4.9 particles m−3 in

An emerging coastal wetland management dilemma between mangrove expansion and shorebird conservation. [PDF]
Conserv Biol, 2022 Abstract Coastal wetlands around the world have been degraded by human activities. Global declines in the extent of important coastal wetlands, including mangroves, salt marshes, and tidal flats, necessitate mitigation and restoration efforts. However, some well‐meaning management actions, particularly mangrove afforestation, can inadvertently cause ...

Spatiotemporal Prediction of Ideal Butterfly Habitats in Kun-Ming's Urban Green Areas: Enabled by Maxent and ArcGIS. [PDF]
Ecol EvolUsing Maxent and ArcGIS with 22 SPSS–selected environmental parameters, this study analysed current butterfly distributions in Kunming's urban green spaces, predicted changes under three climate scenarios (1970–2000, 2030s, 2050s) and generated ecological sensitivity data.

Mechanistic and phylogenetic insights into actinobacteria-mediated oestrogen biodegradation in urban estuarine sediments. [PDF]
Microb Biotechnol, 2021 We identified a gene cluster encoding several putative estrogen‐degrading genes (aed; actinobacterial estrogen degradation) in actinobacterium Rhodococcus sp. strain B50. Among them, the aedA and aedB genes involved in estrogenic A‐ring cleavage were identified through gene‐disruption experiments.

Antimicrobial resistance genes and bacterial diversity in sediments of Guandu River, Brazil
Revista Ibero-Americana de Ciências Ambientais, 2021 Rivers provide essential water resources for humans. However, appear to be reservoirs of antimicrobial-resistant genes and dispersal routes of resistant pathogens because human activities promptly influence them. Sediments are the most propitious substrates for bacteria survival and can act as an antimicrobial reservoir.

A global review of problematic and pathogenic parasites of farmed tilapia
Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023 Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Amplifying the Archive: Methodological Plurality and Geographies of the Black Atlantic
Antipode, Volume 54, Issue 4, Page 1297-1319, July 2022., 2022 Abstract First published in 2001, Judith Carney’s Black Rice drew on a complex methodology to argue that enslaved Africans, despite the brutal oppression of bondage, made fundamental intellectual and cultural contributions to agricultural landscapes and economies in the Americas.
