Structural enrichment reduces aggression in Tilapia rendalli

Environmental enrichment seeks to improve the behavior of captive animals. Few studies have developed enrichment strategies for fish, particularly for use in aquaculture. Environmental enrichment for territorial and aggressive animals has the potential to increase both the amount of defensible resources and the value of a disputed territory which can increase the level of aggression. This study evaluated this hypothesis for the redbreast tilapia, Tilapia rendaIli. We used a short-term approach for evaluation of fish aggressive behavior by recording it for 30 min after introduction of a pair of fish into each experimental aquarium. Our main finding was that the latency to start a fight was lower in an enriched environment, but the frequency of attacks was higher in a non-enriched environment (control). Furthermore, we observed clear hierarchical behavior (submissive dark stripes on the body and dominant light-colored bodies without stripes) only in the non-enriched environment. Structural enrichment of the environment for redbreast tilapia leads to decreased aggression and cohabitation without hierarchical dominance. © 2013 Copyright Taylor and Francis Group, LLC.

Design of experimental composting of animal carcasses in universitary unit of treatment aimed a correct final disposition and soil improve

For many years, composting has been used as a result of the recycling of organic matter. There is significative animal carcasses accumulation from teaching and researching activities of the university veterinary hospital. Every year, Unesp University needs to dispose correctly about 180 tones of this waste and the composting seemed to be the most sustainable alternative. Piles of animal carcasses were prepared using peanut hulls and tree pruning as bulking agent and water to the first phase of this process. The extracts pH values no impediments for offering germination and indicated a good addition to the soil management. The germination index showed no impediment to the seeds germination on any type of compost and the extracts concentrations not influenced this biological process. No parameters studied assigns risks of contamination of carcasses for the compost development in Unesp according to the proposed design. © 2013 Taylor & Francis Group.

Proteome and phosphoproteome of Africanized and European honeybee venoms

Honey bee venom toxins trigger immunological, physiological, and neurological responses within victims. The high occurrence of bee attacks involving potentially fatal toxic and allergic reactions in humans and the prospect of developing novel pharmaceuticals make honey bee venom an attractive target for proteomic studies. Using label-free quantification, we compared the proteome and phosphoproteome of the venom of Africanized honeybees with that of two European subspecies, namely Apis mellifera ligustica and A. m. carnica. From the total of 51 proteins, 42 were common to all three subspecies. Remarkably, the toxins melittin and icarapin were phosphorylated. In all venoms, icarapin was phosphorylated at the 205Ser residue, which is located in close proximity to its known antigenic site. Melittin, the major toxin of honeybee venoms, was phosphorylated in all venoms at the 10Thr and 18Ser residues. 18Ser phosphorylated melittin-the major of its two phosphorylated forms-was less toxic compared to the native peptide. © 2013 WILEY-VCH Verlag GmbH & Co.
