Article Reference Biofluorescence in Morelia, Malayopython and Python: first reports for the Pythonidae
Ultraviolet (UV) induced biofluorescence in snakes has been underexplored compared to lizards. This study reports for the first time UV fluorescence in several Pythonidae species, including Morelia viridis, Malayopython reticulatus, and Python regius. Specimens were examined under both white and UV light, revealing that UV fluorescence in these snakes is likely skin-based, induced by chemical compounds rather than bone-based as seen in other reptiles. Notably, Morelia viridis and M. azurea exhibited a golden mustard yellow fluorescence, while Malayopython reticulatus displayed a complex pattern with intense yellow fluorescence. The study also found that UV fluorescence is absent in ethanol-preserved specimens, suggesting the degradation of fluorescent compounds during preservation. These findings contribute to the understanding of UV fluorescence in snakes and highlight the need for further research on its functional significance and the specific molecules involved.

Article Reference Biomonitoring of lakes using macroinvertebrates: recommended indices and metrics for use in West Africa and developing countries
AbstraitLes systèmes lacustres subissent de fortes pressions qui ont un impact sur leur biodiversité et les services écosystémiques associés. Cela est particulièrement grave en Afrique de l’Ouest et dans les pays en développement, qui manquent de ressources et de capacités techniques pour l’élimination des déchets, la purification de l’eau, ainsi que de capacités scientifiques suffisantes pour la biosurveillance et la gestion intégrée. La préservation, la surveillance et l'amélioration de la qualité des lacs dans ces pays revêtent cependant une importance primordiale. Dans les pays développés, un ensemble d'indicateurs et d'indices multimétriques ont été intégrés à la biosurveillance et à l'évaluation des lacs. Nous évaluons ici les nombreuses procédures, mesures et indices utilisant les macroinvertébrés comme indicateurs de la qualité des lacs et évaluons leur applicabilité dans les lacs d’Afrique de l’Ouest et, plus généralement, dans les pays en développement. Nous proposons un cadre de suivi basé sur les macroinvertébrés adapté à ces pays, incluant des recommandations pour développer de nouveaux indices et adapter les scores de tolérance des taxons aux conditions locales. Ces travaux soulignent l’importance des macroinvertébrés pour la biosurveillance de la santé des lacs dans les lacs d’Afrique de l’Ouest et, plus généralement, dans les pays en développement.

Article Reference ECMAScript program Bioturbation has a limited effect on phosphorus burial in salt marsh sediments
It has been hypothesized that the evolution of animals during the Ediacaran–Cambrian transition stimulated the burial of phosphorus in marine sediments. This assumption is centrally based on data compilations from marine sediments deposited under oxic and anoxic bottom waters. Since anoxia excludes the presence of infauna and sediment reworking, the observed differences in P burial are assumed to be driven by the presence of bioturbators. This reasoning however ignores the potentially confounding impact of bottom-water oxygenation on phosphorus burial. Here, our goal is to test the idea that bioturbation increases the burial of organic and inorganic phosphorus (Porg and Pinorg, respectively) while accounting for bottom-water oxygenation. We present solid-phase phosphorus speciation data from salt marsh ponds with and without bioturbation (Blakeney salt marsh, Norfolk, UK). In both cases, the pond sediments are exposed to oxygenated bottom waters, and so the only difference is the presence or absence of bioturbating macrofauna. Our data reveal that the rate of Porg and Pinorg burial are indistinguishable between bioturbated and non-bioturbated sediments. A large terrestrial fraction of organic matter and higher sedimentation velocity than generally found in marine sediments (0.3 +/- 0.1 cm yr-1) may partially impact these results. However, the absence of a clear effect of bioturbation on total P burial puts into question the presumed importance of bioturbation for phosphorus burial.
