Aedes (Ochlerotatus) sallumae González & Reyes n. sp. is described and validated using morphological characters of the adult male and female, male genitalia and immature stages, and its cytochrome oxidase unit 1 mitochondrial gene sequence (COI). Aedes (Och.) sallumae is morphologically close to Ae. (Och.) albifasciatus (Macquart). However, these species can be distinguished based on characters of the males and females, male genitalia and fourth-instar larvae. Aedes (Och.) sallumae was collected in the geographically isolated desert zone of northern Chile, the Atacama Desert. This isolation suggests allopatric speciation, with Ae. (Och.) sallumae divergent from its sister species Ae. (Och.) albifasciatus. Molecular characterization showed a difference of more than 8% between these species, supporting their recognition as different species.

The ecological value of coastal wetlands is globally recognized, particularly as biodiversity hotspots, but also as buffer areas because of their role in the fight against climate change in recent years. Most of Chile’s coastal wetlands are concentrated in the central and southern part of the country due to climate conditions. However, northern coastal wetlands go unnoticed despite being located in areas of high water deficit (desert areas) and their role in bird migratory routes along the north–south coastal cordon of South America. This study reviews the current environmental status of the arid coastal wetlands of northern Chile (Lluta, Camarones, Loa, La Chimba, Copiapó, Totoral, Carrizal Bajo) in terms of regulations, management, and future aims. The main natural and anthropogenic threats to these coastal wetlands are identified, as well as the main management tools applied for their protection, e.g., the Nature Sanctuary designation, which allows for the protection of both privately and publicly owned property; and the Urban Wetland, a recently created protection category.

Algae has a great potential for quick capture of biological carbon and its storage in saltwater-inundated coastal wetlands and can also be introduced as a climate adaptive alternate farming practice. An intervention with native algal flora Enteromorpha sp. in enclosed coastal Sundarbans in India on two open water culture techniques, viz. U-Lock & Fish-Bone, shows that growth in native algal stock is influenced by seasonal variations of salinity and other limnological factors. Sundarbans, facing the odds of climate change is fast loosing arable lands to sea level rise. Algaculture in inundated coastal areas can be an adaptive mitigation for the same. Perusal of results show that daily growth rate (DGR%) increases with increasing salinity of the intruding tidal waters to an extent and biomass increment under salt stress results in accumulation of metabolites those are having nutrient values and can yield bio-diesel as well. Algal growth recorded mostly in post monsoon period, has impacts on pH and Dissolved Oxygen (DO) of the ambient water to facilitate integrated pisciculture. The paper suggests that alga-culture has unrealized potentials in carbon sequestration and can be significantly used for extraction of Biodiesel.
