Microplastic presence in the marine environment has generated considerable concern. Many procedures for microplastics detection in fish gastrointestinal tract have been recently developed. In this study, we compared efficiencies of two common procedures applied for the digestion of organic matter (10% KOH; 15% HO) with a new proposal (mixture of 5% HNO and 15% HO). We considered ecological diversity among species and differences in their diet compositions as factors that could affect the efficiency and feasibility of analytical approaches. Our aim was to understand whether either one of the three protocols might be suitable for all species or it might be more advisable to select a method according to the gut content determined by different food preferences. The results showed that the trophic level and feeding habits should be considered for protocol selection. Finally, we applied the best protocols on samples from the Tyrrhenian sea.

Pharmacological modulation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) through dual GIP/GLP-1 receptor agonists, commonly used for diabetes and obesity, shows promise in reducing alcohol consumption. We applied drug-target Mendelian randomization (MR) using genetic variation at these loci to assess their long-term effects on problematic alcohol use (PAU), binge drinking, alcohol misuse classifications, liver health, and other substance use behaviors. Genetic proxies for lowered BMI, modeling the appetite-suppressing and weight-reducing effects of variants in both the GIPR and GLP1R loci ("GIPR/GLP1R"), were linked with reduced binge drinking in the primary (β = -0.

In western North America, 3 pest wireworms in the genus Limonius co-occur on farmland, and the click beetle adult males respond to the same single-component sex attractant, limoniic acid. While divergence in seasonal occurrence may provide a means of separating sexual communication for Limonius canus (LeConte) and Limonius californicus (Mann.), both species overlap temporally with Limonius infuscatus (Mots.

Application of anesthetic chemicals in aquaculture is important to minimize stress under normal operations such as handling, transport, and artificial breeding. In the past decade, the preference for natural anesthetics over synthetic ones has increased due to welfare issues regarding fish welfare and food safety. This study investigates the anesthetic efficacy of nutmeg oil () in three freshwater fish species- (Common carp), (Danube sturgeon), and (Rainbow trout)-by modeling behavioral (Induction and recovery times) and hematological responses using artificial neural networks (ANNs).

Background: The relationships between floral traits and pollinators have been extensively studied over the last few decades. The concept of pollination syndrome suggests that plants pollinated by the same group of pollinators tend to develop similar combinations of floral traits. However, several studies have demonstrated the low predictability of these trait combinations and found high levels of pollination generalization within plant communities.

Floodplains support a diverse cichlid community, yet the trophic ecology of these species is not well understood. This study investigated the dietary niches and trophic guilds of cichlid species in the Cross River floodplain. A total of 480 fish samples from eight cichlid species were collected from three locations (Itu, Obubra, Ikom) over 6 months (October 2019-March 2020).
