Fish loss in tropical coastal ecosystems can jeopardise nutrient supply to traditional fishing communities: A case study from Northeast Brazil

People and Nature, EarlyView.
Abstract Fisheries constitute one of the major benefits that oceans provide for people. Yet anthropogenic pressures and global changes are disrupting coastal systems, eroding marine biodiversity and threatening the food security of traditional populations.

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Towards a Just Coastal Transition: The Mixed Success of Livelihood Diversification and ‘Bouncing Back’ Among Seaweed Farmers in Sorsogon Province, the Philippines

Asia Pacific Viewpoint, EarlyView.
ABSTRACT The need to integrate localised settings of coastal communities within its wider marine and landscapes calls to provide contextualised assessments. Drawing upon the ambition of the Philippines to identify opportunities for enhancing coastal livelihoods, the potential of seaweed farming accruing to high productivity in many of its regions is ...
