This perspective provides empirical data on the Ramsar Convention and gender equity. This paper assessed how Ramsar Convention complied with its own goals for gender mainstreaming in 2018, guided by the Global 2018 Gender and Wetlands Resolution agreed upon by 171 nations. The data were derived from National Reports from around the world. The findings shed light on the room for improvement in gender mainstreaming and gender equity in the wetland science and policy.

We investigated the immune responses in the respiratory tree of sea cucumber (Apostichopus japonicus) to high temperature, oil pollution, and the combined stress of high temperature and oil pollution. We found that acute exposure to oil pollution may have affect the immune function of sea cucumbers, whereas high temperature may exacerbate the health challenges of sea cucumbers subjected to environmental stress.

To explore climate effects on tiny aquatic life, we delved into how changes in water conditions affect Moina micrura, a small freshwater creature. Results showed that extreme pH harms the offspring and slows the heartbeat of this species, but warmth and longer daylight boost the numbers. Interestingly, M. micrura produces more males when food is scarce. This research informs strategies to protect these creatures in our tropical waters.

The InVEST water-yield model and support-vector regression (SVR) model were utilised to assess and forecast the ecosystem water-regulation value in Qinghai Area of Qilian Mountain National Park, China. The research showed that grassland plays a crucial role in regulating water, with an anticipated increase in both physical and monetary values by 2030. To further enhance monitoring efforts, it is recommended to establish an ecological big-data platform within the park.

Exploring what fish eat is important to understand how changes in the environment can affect their lives. In this study, we looked into the diet of an Amazonian catfish in a river affected by the construction of a dam. We found that the catfish mostly fed on sediment and aquatic insects, and these feeding habits were not strongly influenced by changes in the local water levels.

Crayfish are important freshwater invertebrates both ecologically and economically. In Turkey, there is no aquaculture of this species, and it is solely produced through fishing. Owing to poor size selectivity of the fyke-nets used in harvesting this species, the rate of undersized catch is quite high (40.7%). This study aimed to enhance the size selectivity of fyke-nets through various manipulations.

This study investigated habitat use and movements of trout cod using radio-telemetry. Trout cod typically occupied small (<300 m) reaches of stream, undertook larger-scale movements and moved onto inundated riparian habitats during high flows. It occupied deeper water bank during the day and shallower water during the night and used areas with slower velocities more than was their availability. It also made extensive use of in-stream cover (i.e. wood). (Photograph by W. M. Koster.)
