This study aimed to identify the existent of microbiota in the fresh semen of collared peccary (Pecari tajacu), kept in captivity, and their susceptibility patterns to antimicrobial drugs. Ten males of this species were submitted into experimental induced ejaculation procedures throughout 14 months. The microorganisms found in the semen were evaluated within the following criteria: morphology, biochemistry, colony forming unit (CFU mL-1), and antibiotic sensitivity. 225 Gram-positive strains were isolated, out of 88 samples. They were identified as following: Streptococcus (30.2%), Staphylococcus (30.2%), Micrococcus (33.7%), Corynebacterium (2.2%), Enterococcus (1.7%), and Bacillus (1.7%). The cell counting of contaminated semen material was under 300 CFU mL-1. The evaluation of sensitivity against eleven antibiotics revealed that most of the bacteria found were sensitive to Gentamicin, Cephalothin, Amikacin, Ampicillin, Ceftriaxone, Cephotaxin and Penicillin. During the evaluation period, the presence of microorganisms in the semen here analyzed did not influence the quality of the semen production of the donor animals. Semen contamination is probably coming from the surrounding environment in which the animals were kept, during collection procedures. This study suggests that Gentamicin and Amikacin are better choices over Tetracycline as diluters of collared peccary's semen.

“…Since the publication of appropriate R functions by Neumann et al . ( 2011 ), use of Elo-ratings to model dominance hierarchies and to derive ranks for additional analyses has blossomed, such that this may now be the default method within studies of nonhuman primates (Cassalette et al 2016 ; da Silva et al 2016 ; Fedurek et al 2015a ; Franz et al 2015 ; Kaburu 2013 ; Kaburu and Newton-Fisher 2013 , 2015a ; Murray et al 2016 ; Pusey et al 2016 ; Schoof et al . 2016 ; Spillmann et al .…”

Modeling Social Dominance: Elo-Ratings, Prior History, and the Intensity of Aggression

Among studies of social species, it is common practice to rank individuals using dyadic social dominance relationships. The Elo-rating method for achieving this is powerful and increasingly popular, particularly among studies of nonhuman primates, but suffers from two deficiencies that hamper its usefulness: an initial burn-in period during which the model is unreliable and an assumption that all win–loss interactions are equivalent in their influence on rank trajectories. Here, I present R code that addresses these deficiencies by incorporating two modifications to a previously published function, testing this with data from a 9-mo observational study of social interactions among wild male chimpanzees (Pan troglodytes) in Uganda. I found that, unmodified, the R function failed to resolve a hierarchy, with the burn-in period spanning much of the study. Using the modified function, I incorporated both prior knowledge of dominance ranks and varying intensities of aggression. This effectively eliminated the burn-in period, generating rank trajectories that were consistent with the direction of pant-grunt vocalizations (an unambiguous demonstration of subordinacy) and field observations, as well as showing a clear relationship between rank and mating success. This function is likely to be particularly useful in studies that are short relative to the frequency of aggressive interactions, for longer-term data sets disrupted by periods of lower quality or missing data, and for projects investigating the relative importance of differing behaviors in driving changes in social dominance. This study highlights the need for caution when using Elo-ratings to model social dominance in nonhuman primates and other species.Electronic supplementary materialThe online version of this article (doi:10.1007/s10764-017-9952-2) contains supplementary material, which is available to authorized users.
