Fish community composition in the tropical archipelago of São Tomé and Príncipe.

Understanding species distribution across habitats and environmental variables is important to inform area-based management. However, observational data are often lacking, particularly from developing countries, hindering effective conservation design. One such data-poor area is the Gulf of Guinea, an understudied and biodiverse region where coastal waters play a critical role in coastal livelihoods.

The Effect of Cushioned Centrifugation, with and without Enzymatic Reduction of Viscosity, on the Motility Pattern and Kinematic Parameters of Dromedary Camel Bull Spermatozoa.

In order to contribute to the development of semen processing procedures in camelids, the aims of the present study were to evaluate (i) the effect of 35% seminal plasma incubation on dromedary camel epididymal sperm motility and kinematic parameters, (ii) the effects of centrifugation, with cushion fluid and enzymatic reduction of viscosity (Papain + E64) during ejaculate processing, on the motility and kinematic parameters of dromedary camel ejaculates. The incubation with seminal plasma significantly reduced the percentage of progressively motile spermatozoa as well as the proportion of medium progressive spermatozoa whilst increasing the percentage of non-progressive spermatozoa. The centrifugation procedure improved the sperms' kinematic parameters, and the highest values were observed for samples centrifugated with cushion fluid.

A comparison of culture and cooling for the short term preservation of in vivo derived dromedary camel embryos of varying morphological quality.

Despite recent advancements in the cryopreservation of dromedary camel embryos, widespread application of the technique is still limited by the need for specialised vitrification equipment and supplies. Temporary, liquid-phase embryo storage methods provide a useful tool for short-term preservation of camel embryos. In the current study, we compared the use of in vitro embryo culture with cold liquid storage in order to maintain both high- (Grade 1- Excellent and 2-Good) and low- (Grade 3- Moderate and 4-Poor) morphological grade Day-7 dromedary camel embryos in vitro for up to 3 days.

Mindfulness-Based Stress Reduction for Our Time: A Curriculum that is up to the Task.

There is current heightened public consciousness of the intersecting challenges of social and racial injustice, other forms of inequity, and the climate and biodiversity crisis. We examine how these current realities influence how we engage as Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Program (MBP) teachers and researchers. Although Kabat-Zinn developed MBSR as a vehicle to enable engagement with both the individual and the collective drivers of distress and flourishing, predominant research and practice trends within the MBP field have prioritised individual wellbeing, and have not been accessible to the full societal demographic.
