The Alaotran gentle lemur (Hapalemur alaotrensis) is one of the world’s most endangered primates and shows low success rates in captive breeding programmes. This study tested biologically relevant scent enrichment using two synthesised mixtures likely to convey information about female fertility on behaviour three unsuccessful pairs captivity. Specifically, we compared baseline periods by combining behavioural observations (n = 240 h) with faecal endocrinology 80 samples), focussing cortisol testosterone measurements via enzyme immunoassay techniques. Then, different assess potential differences evaluate effectiveness olfactory scented unscented cotton strips. Olfactory behaviours differed sex conditions, both sexes exhibiting increased during baseline. Sexual period, variations frequency between males females depending condition. No significant changes were observed levels. However, male showed a increase second mixture. Nevertheless, overall not significant. Our findings suggest that while limited effectiveness, meaningful scents may trigger species-specific behaviours.

The zoo is a unique environment in which to study animals. Zoos have long history of research into aspects animal biology, even if this was not the primary purpose for they were established. data collected from animals can great biological relevance and it tell us more about what these are like outside captive environment. In order ensure health all animals, important perform post-mortem examination on that die captivity.The causes mortality two hundred eighty mammals died between 2004 2015 three different Italian zoos (a Biopark, Safari Park private conservation center) been investigated.Post mortem findings evaluated reporting cause death, type, year category. frequently infectious diseases, particular death ruminants mostly related gastro-intestinal pathologies. pulmonary diseases also very common each study. Moreover, sometimes attributable traumas, as result fighting conspecifics or during mating.

Background Conventional in vivo methods for post-translational modification site prediction such as spectrophotometry, Western blotting, and chromatin immune precipitation can be very expensive time-consuming. Neural networks (NN) are one of the computational approaches that predict effectively site. We developed a neural network model, namely Sequential Spatial Methylation Fusion Network (SSMFN), to possible methylation sites on protein sequences. Method designed our model able extract spatial sequential information from amino acid Convolutional (CNN) is applied harness information, while long short-term memory (LSTM) data. The latent representation CNN LSTM branch then fused. Afterwards, we compared performance proposed state-of-the-art models balanced imbalanced dataset. Results Our appeared better almost all measurement when trained training On dataset, gave since they more In several metrics, also surpasses PRMePred which requires laborious effort feature extraction selection. Conclusion achieved best across different environments measurements. Also, result suggests NN dataset tested an will offer high specificity low sensitivity. Thus, should Since actual application, there far negative samples than positive samples.
