“…Although not a notable factor in the Komuke Lagoon system, the social risks of the intervention should be evaluated in the decision‐making process because many lagoon systems across the world contain rich ecosystems, which, in turn, support people with food and livelihood. The artificial introduction of tidal flow increases salinity, which may damage resident plant and animal species that prefer low‐salinity conditions (Conde et al., 2015; Serrano et al., 2020). For example, salinization due to inlet opening negatively affected the oyster fishery and triggered the subsequent development of scallop farming in Saroma Lagoon (Katsuki et al., 2009).…”

“…These hydrological interventions have provided both positive and negative unintended feedbacks for various ecosystem functions (Ghosh et al, 2006). For example, artificial inlet opening to avoid flooding facilitated the migration and growth of economically important marine fishes in eastern Australia (Griffiths, 1999), whereas artificial inlet opening for shipping stressed resident mangrove species through salinization on the eastern Pacific coast in Mexico (Serrano et al, 2020). However, little is known about how hydrological interventions alter carbon sequestration, one of the most important functions in shallow coastal ecosystems.…”

“…The inlet's habitats could also be variously affected by sea level rise, which is expected to more severely affect the Mediterranean in comparison to other areas (Church et al 2013). However, possible changes in the wetland resources necessary for the fulfillment of waterbird needs are hard to predict and understand without experimentation (McCoy et al 2020;Serrano et al 2020). Therefore, future research should focus on the study of species interactions and the assessment of habitat quality and suitability for waterbirds by including measures of food availability, energy intake, salinity, water quality, waste and pollution levels.…”

Background Small coastal wetlands are vital sites for wintering waterbirds. Identifying important habitats is critical for managing waterbirds effectively. The Vourkari inlet is a small coastal wetland located near the capital Athens, within the most urbanized and industrialized area of Greece. We aimed at identifying the most important habitats for waterbirds at the Vourkari inlet during winter. Methods Data about habitat use and availability were collected for 14 waterbird species and for seven habitat classes. Habitat selection (Manly’s selection ratio), overlap indices (Pianka’s niche overlap index) and null models were calculated. Results All the studied waterbird species selected available habitats nonrandomly. Shallow waters (0–2 m), were used by 13 waterbirds and selected by five waterbirds. Pools and channels were used and selected by 10 species. Mud was used by nine species and selected by six species. Mud with rocky substrate was used by nine species and selected by eight species. Medium (2–4 m) and deep (4–6 m) open water habitats were used by seven species and selected by four species. Halophytic vegetation was used by six species and selected by two species. Several habitats were selected by nationally important populations: mudflat habitats (i.e., mud, mud with rocky substrate and pools and channels) by Common Redshanks (Tringa totanus), halophytic vegetation by Little Egrets (Egretta garzetta), shallow waters by Common Shelducks (Tadorna tadorna) and medium and deep waters by Sandwich Terns (Thalasseus sandvicencis), whilst shallow waters and mudflat habitats were preferred by a possibly internationally important population of Mediterranean Gulls (Ichthyaetus melanocephalus). Although overlap in habitat use between species was generally low, null models indicated habitat sharing and a lack of competition. Conclusions Waterbirds coexisted in the absence of competition for habitats at Vourkari, where they mostly used and preferred shallow water and mudflats. Small coastal wetlands are numerous, both in Greece and worldwide, therefore our findings would be useful as a basis for comparisons, both temporal at the inlet and spatial with other sites, that would help assess the importance of habitats and improve management strategies to benefit waterbirds, especially in areas with similar Mediterranean-type habitats and climate.

“…(2012) and Serrano et al. (2020), the hydrological conditions of the estuarine system were under a certain degree of stability before the opening of the Cuautla Channel, with a predominant oligohaline condition (0.5–3.0 psu) due to the presence of 12 unobstructed rivers and the lack of seawater intrusion through the Teacapán Inlet according to the sea‐level elevation model designed by Serrano et al. (2020).…”

Biological parameters relating to the reproductive biology of Conguito Sea Catfish Cathorops liropus were investigated in 1979-1984 and 2015-2018 from an estuarine system on the northwestern Pacific coast of Mexico. In the first period, the spawning season occurred during the dry-warm season (April-June), according with the percentage of mature females and the highest gonadosomatic index (GSI) values. Mean TL was 12.3 cm, two cohorts were found, length at maturity was 18.6 cm, and fecundity was 24.47 oocytes/organism. In the second period, the spawning season extended to the rainy-warm season (July-November), as reflected by the percentage of mature females and the GSI values. Mean TL was 11.6 cm, length at maturity decreased to 17.1 cm, and fecundity decreased to 20.67 oocytes/organism, indicating a reduction in the size-based indicators and a change in the spawning period and reproductive effort as time passed. The number of fishing skiffs increased from 1,103 in 1980 to 2,434 in 2019, representing a 220% increase, and the landings increased from 400 to 3,432 metric tons in the same period. Temporal trends in surface water temperature, salinity, and the Oceanic Niño Index did not explain the observed changes between the study periods. These results suggest that the observed changes in the reproductive potential of Conguito Sea Catfish have been at least partially due to fishing.
