The reproductive biology of the starry grouper, Epinephelus labriformis , in Mazatlan Bay, Mexico, was studied through histological analysis of the gonads. A total of 527 fish were examined through weekly sampling from March 2017 to March 2018. In this species, the gonads are bilobed and connected to a common gonoduct. E. labriformis exhibits monandric protogynous hermaphroditism, with a female‐to‐male proportion of 1.5 female...

Parthenocarpy is a valuable trait for greenhouse squash production, but the molecular basis of fruit set without pollination or fertilization remains unclear. The ethylene-insensitive etr2b mutation confers parthenocarpic fruit development, indicating that ethylene acts as a negative regulator of fruit set. Here, we analyzed the hormonal profile, the transcriptomic and epigenetic changes occurring in unfertilized ovaries of bo...

Reproductive biology is fundamental for understanding fish population dynamics and for guiding fisheries management and aquaculture practices. Key reproductive and fishery-related variables such as catch size, age at maturity, spawning season, aggregation behavior, and the implementation of seasonal closures are critical to ensuring fish population sustainability. Snappers have been targeted for commercial aquaculture developm...

This study documents an ecotoxicological evaluation of bottom sediments ( n = 21) from a tropical lagoon complex performed in the Itaipu-Piratininga system (Rio de Janeiro State), an impacted urban tropical estuary. To achieve this purpose, three lines of evidence were adopted: sediment characterization, metal contamination and toxicity to tropical species (bioassays with mussels Perna perna , tanaids Kalliapseudes schubartii...

Background Urban greenspaces have the potential to mitigate urban carbon footprints by storing soil organic carbon (SOC). Different management and plant communities associated with different types of urban greenspaces may hold contrasting SOC, as well as different proportions of particulate (POC) and mineral-associated organic carbon (MAOC). In addition, management could outweigh the effects of climate or soil properties as dr...

Reducing uncertainty in climate change projections is essential for developing reliable impact assessments and effective adaptation strategies in water resource management. Climate model sub-selection has become a key tool for managing large ensembles; however, trade-offs between accuracy, uncertainty coverage, and spatial consistency remain insufficiently explored. This study introduces a standardised multi-criteria framework...

Key Biodiversity Areas (KBAs) are sites of significance for the global persistence of biodiversity. Based on the Global Standard for the Identification of Key Biodiversity Areas (KBA Standard), published in 2016, sites are currently being assessed for KBA designation in a growing number of countries across the world. For these assessments, the KBA criteria are applied to all species and ecosystems with available data. We revie...
