Pełniejszy materiał źródłowy / excerpt

Fish are very diverse animals and can be categorised in many ways. Although most fish species have probably been discovered and described, about 250 new ones are still discovered every year. According to FishBase, about 34,800 species of fish had been described as of February 2022, which is more than the combined total of all other vertebrates: mammals, amphibians, reptiles and birds. Fish species are is divided roughly equally between marine (oceanic) and freshwater ecosystems. Coral reefs in the Indo-Pacific region constitute the center of diversity for marine fishes, whereas continental freshwater fishes are most diverse in large river basins of tropical rainforests, especially the Amazon, Congo, and Mekong basins. More than 5,600 fish species inhabit Neotropical freshwaters alone, such that Neotropical fishes represent about 10% of all vertebrate species on the Earth. Exceptionally rich sites in the Amazon basin, such as Cantão State Park, can contain more freshwater fish species than occur in all of Europe.

Biomonitoring of Microplastics in Izmir Bay (Eastern Aegean Sea): Abundance, Polymer Characterization, and Ecological Risk Assessment in Saddled Seabream, <i>Oblada melanurus</i> (Linnaeus, 1758).. In this study, we aimed to investigate the occurrence, characteristics and temporal dynamics of microplastics (MPs) in the gastrointestinal tracts of saddled seabream ( Oblada melanurus ) from Izmir Bay (Eastern Aegean Sea). Sampling was carried out monthly during a one-year period (March 2021-February 2022) and MPs were identified by stereomicroscopy and ATR-FTIR spectroscopy. Microplastics were identified in 115 of the 180 examined individuals, representing an overall frequency of o…

Effects of the Allelopathic Macroalga <i>Galaxaura divaricata</i> on the Foraging Behaviors of Reef Fishes Across Herbivorous and Nonherbivorous Feeding Guilds.. Macroalgal overgrowth-induced phase shifts pose a significant threat to coral reef ecosystems. While herbivores can help control macroalgae biomass in reefs, some allelopathic macroalgae can resist herbivores from foraging. This resistance can lead to a decrease in herbivory levels. However, the impact of these allelopathic effects on other feeding groups of reef fish remains unclear. We examined the presence of the allelopathic macroalga: Galaxaura divaricata on the foraging behaviors of various reef fish species from…
