The present investigation was conducted to study the morphology, production potential and genetic architecture of Red Jungle Fowl (Gallus gallus) kept in captivity. Records of 104 birds of RJF (65 males and 39 females) were utilized in study. Males had prominent plumage pattern with neck hackles, greenish black tails, and prominent bright red single comb, while females were comparatively smaller with very small combs. RJF are seasonal breeder having small clutch and egg size. Observed and effective number of alleles across the microsatellite loci varied from 5-18 with an overall mean of 10.28 and 5.04, respectively. The average expected heterozygosity and observed heterozygosity were 0.492 and 0.758 respectively. Study revealed existence of population structure accompanied by higher inbreeding along with sufficient heterozygosity. The effort must be directed to introduce unrelated typical RJF in to the present population to maintain heterozygosity and ensure conservation of unique germplasm.

Ornamental Species

The present work aimed to review the literature on studies carried out on the “acari-zebra” (Hypancistrus zebra Isbrücker & Nijssen, 1991). The data search was performed in four scientific databases (Capes journals, Google Scholar, Scielo, ScienceDirect and Web of Science Core Collection), using the scientific and common name of the species as keywords. Articles were selected when they had any of the keywords used in the title or abstract, excluding works from gray literature. After selecting the articles in the scientific databases, a careful reading was carried out in order to characterize the taxonomy, biology, ecology, fisheries and conservation status of H. zebra. The “acari-zebra” is an ornamental species endemic to the Xingu River basin, which has a high economic value internationally. It was recently added to the endangered species list due to overfishing of the species. Literature on H. zebra proved to be very scarce, with only basic information on taxonomy, fisheries, reproductive aspects and studies aimed at cultivation. Among the studies to be carried out, we highlight the characterization of growth and reproductive dynamics. These studies will enable a better understanding of the biology of the species and will contribute to a definition of the technological package of reproduction in captivity.

In order to preserve and conserve the Giant African Land Snails, a study was carried out between September 2015 and January 2017 at the University of Buea (South-West Region, Cameroon), to assess the effect of protein level on the characteristics of growth of Achatina achatina in captivity. 90 young snails of one month old, weighing between 1 and 1.5 g, of shell length between 15.5-23.85 mm and shell diameter between 12.60-16.85 mm and free from wounds or shell defects were divided into 3 groups of 5 snails each and 6 replicates in cages equipped with feeders and drinking troughs. Each treatment was randomly assigned to one of the experimental feed with variable protein levels (20, 22 and 24%) in addition to pawpaw leaves as a staple feed. These were previously weighed as well as the remnants using a 0.5g precision balance. The cultured substrates were watered daily (0.50 liter/substrate). At the beginning of the test, and then every week, the snails were weighed, and shell measurements done using a digital caliper of 0.05 mm accuracy. The animals were monitored for fourteen months. The results show that feed intake (3.01±1.57), weight gain (24.50±5.72), daily weight gain (0.058±0.016), gain of shell length (30.26±4.19) were significantly higher (P < 0.05) in snails receiving 24% protein in the diet compared to snails from the other treatments. The highest consumption index was recorded in snails receiving 20% protein in the diet but the statistical analyses did not find any significant difference. In conclusion, the protein level of 24% can be retained in the diet of growing snails.

ABSTRACT Animals, including humans, have evolved in the context of exposure to a variety of microbial organisms present in the environment. Only recently have humans, and some animals, begun to spend a significant amount of time in enclosed artificial environments, rather than in the more natural spaces in which most of evolution took place. The consequences of this radical change in lifestyle likely extend to the microbes residing in and on our bodies and may have important implications for health and disease. A full characterization of host-microbe sharing in both closed and open environments will provide crucial information that may enable the improvement of health in humans and in captive animals, both of which experience a greater incidence of disease (including chronic illness) than counterparts living under more ecologically natural conditions. Examining the way in which animals, including those in captivity, interact with their environment is extremely important for studying ecological processes and developing sophisticated animal husbandry. Here we use the Komodo dragon (Varanus komodoensis) to quantify the degree of sharing of salivary, skin, and fecal microbiota with their environment in captivity. Both species richness and microbial community composition of most surfaces in the Komodo dragon’s environment are similar to the Komodo dragon’s salivary and skin microbiota but less similar to the stool-associated microbiota. We additionally compared host-environment microbiome sharing between captive Komodo dragons and their enclosures, humans and pets and their homes, and wild amphibians and their environments. We observed similar host-environment microbiome sharing patterns among humans and their pets and Komodo dragons, with high levels of human/pet- and Komodo dragon-associated microbes on home and enclosure surfaces. In contrast, only small amounts of amphibian-associated microbes were detected in the animals’ environments. We suggest that the degree of sharing between the Komodo dragon microbiota and its enclosure surfaces has important implications for animal health. These animals evolved in the context of constant exposure to a complex environmental microbiota, which likely shaped their physiological development; in captivity, these animals will not receive significant exposure to microbes not already in their enclosure, with unknown consequences for their health.

Decision-support systems benefit from hidden patterns extracted from digital information. In the specific domain of gastropod characterization, morphometrical measurements support biologists in the identification of land snail specimens. Although snails can be easily identified by their excretory and reproductive systems, the after-death mollusk body is commonly inaccessible because of either soft material deterioration or fossilization. This study aims at characterizing Brazilian land snails by morphometrical data features manually taken from the shells. In particular, we examined a dataset of shells by using different learning models that labeled snail specimens with a precision up to 97.5% (F1-Score = .975, CKC = .967 and ROC Area = .998). The extracted patterns describe similarities and trends among land snail species and indicates possible outliers physiologies due to climate traits and breeding. Finally, we show some morphometrical characteristics dominate others according to different feature selection biases. Those data-based patterns can be applied to fast land snail identification whenever their bodies are unavailable, as in the recurrent cases of lost shells in nature or private and museum collections.
