Summary: In Brazil, official fisheries statistics are lacking to assess the status of target and bycatch species quantitatively. The Productivity and Susceptibility Analysis (PSA), a widely used data-poor method, is employed to evaluate the impact of a shrimp fishery in northeastern Brazil known for adverse ecological effects. PSA, compared with other methods, can serve as a valuable preliminary assessment for data-poor fisheries. Integrated use of multiple methods is advisable, while understanding each technique's peculiarities is essential for its applicability and feasibility.

Summary: "Disturbances in the pine forests of Mexico, primarily caused by cattle, horses, goat, and sheep grazing, have resulted in low tree recruitment, establishment of invasive shrubs, changes in species composition, and invasion of weeds primarily spread by livestock. This study compared a grazing-excluded pine forest stand with a nearby area subjected to livestock grazing in the Sierra de Zapaliname natural protected area in northeast Mexico. The results showed that grazing has altered the understory species composition and reduced evenness in the control plots. To maintain species diversity and forest structure, it is recommended to restrict extensive grazing or reduce the number of animals in areas of high ecological value."

Summary: Crop pollination is a crucial factor in agricultural production, with varying benefits depending on the level of pollinator-dependent crops and biodiversity. Municipalities with greater crop pollination demand may face vegetation deficit issues, especially in large properties with monocultures. Ecological restoration and vegetation conservation can play a key role in promoting crop productivity and ensuring food security in small properties. Land-use management policies based on legal requirements may successfully enhance agricultural sustainability and crop production.

Summary: This study used catch/effort (CPUE) and length-frequency (L/F) data to evaluate the status of 26 fish species in the mangroves of the Dongzhaigang National Reserve, China. The results showed that fishing effort and biomass of the fish species decreased since 2009, with pollution from shrimp, pig, and duck farming being a major factor. Some fish species also experienced a reduction in length, indicating overfishing. To ensure the sustainability of the fisheries, fishing effort should be reduced, similar to the successful pollution reduction efforts in the past.

Summary: This study analyzed the population structure of Farfantepenaeus subtilis off Sergipe, northeastern Brazil by comparing different sampling methods. The results showed that females were larger and heavier than males in both fishing fleets from Aracaju and Pirambu. In addition, inflexion points were observed in the relationships between total length and carapace length, and the weight-length relationships indicated negative allometry. The size at first maturity for females was slightly higher in Aracaju compared to Pirambu, and the reproduction of the shrimp population was continuous with a peak observed in September-October.

Summary: This study evaluates the impact of considering ageing error and growth variability on the determination of input sample size (ISS) in statistical catch-at-age assessment models. The results show that including these sources of uncertainty decreases the ISS determined through bootstrap methods. This indicates that there is more variability in age composition and conditional age-at-length data than previously accounted for. Including these sources of uncertainty improves the estimation of ISS and subsequently improves the quality of stock assessment models.
