Ebook "Reproduction and fitness in baboons: Behavioral, ecological, and life history perspectives" will address the questions of life history and reproduction by attempting to isolate the various components of reproductive success and fitness in baboons. This requires assembling research interests in morphology, behavior, ecology, and endocrinology of the five subspecies of Papio baboons.

Results of this study provide insights into the effects of PRRSV isolate, tonsil viral level, and WUR genotype on host immune response and into potential mechanisms of PRRSV persistence in tonsils that could be targeted to improve strategies to reduce viral rebreaks.

Reproduction is a basic prerequisite to efficient livestock production. Reproductive performance depends on the normal structure and function of genital organs. A cross-sectional study was conducted from November 2016 to May 2017 to identify and compare the frequency of reproductive tract pathological lesions and to isolate bacteria associated to uterine lesions in female dromedary camels and cows slaughtered at Akaki camel slaughterhouse and Addis Ababa and Adama municipal abattoirs.

In plants, GABA plays a critical role in sexual plant reproduction; however, GABA receptors and the associated detailed signaling mechanisms remain to be elucidated. Our experiments show that the proposed technique is reliable and convenient for probing GABA-binding proteins and could be applicable in similar projects by covalently immobilizing the free carboxylic group of GABA on magnetic beads (SiMAG-Carboxyl). New probes produced by covalently immobilizing the free carboxylic group of GABA on magnetic beads (SiMAG-Carboxyl) can obtain useful information on GABA receptors in plants.

Species interactions can promote mating behavior divergence, particularly when these interactions are costly due to maladaptive hybridization. Selection against hybridization can indirectly cause evolution of reproductive isolation within species, a process termed cascade reinforcement. This process can drive incipient speciation by generating divergent selection pressures among populations that interact with different species assemblages.

The bacterial pathogen Mycoplasma synoviae can cause subclinical respiratory disease, synovitis, airsacculitis and reproductive tract disease in poultry and is a major cause of economic loss worldwide. The M. synoviae strain MS-H was developed by chemical mutagenesis of an Australian isolate and has been used as a live attenuated vaccine in many countries over the past two decades. As a result it may now be the most prevalent strain of M. synoviae globally.

The diversity of avian eggshell colour plays important biological roles in ensuring successful reproduction. Eggshell colour is also an important trait in poultry, but the mechanisms underlying it are poorly understood in ducks. This study aimed to provide insights into the mechanism of blue-green eggshell colour generation

The reproductive plasticity of termite workers provides colonies with tremendous flexibility to respond to environmental changes, which is the basis for evolutionary and ecological success. Although it is known that all colony members share the same genetic background and that differences in castes are caused by differences in gene expression, the pattern of the specific expression of genes involved in the differentiation of workers into reproductives remains unclear.

In evolutionary theory, divergence and speciation can arise from long periods of reproductive isolation, genetic mutation, selection and environmental adaptation. After divergence, alleles can either persist in their initial state (ancestral allele - AA), co-exist or be replaced by a mutated state (derived alleles -DA).

It has been recognized that a certain amount of habitat disturbance is a facilitating factor for the occurrence of natural hybridization, yet to date we are unaware of any studies exploring hybridization and reproductive barriers in those plants preferentially occupying disturbed habitats.

Urinary Tract Infection (UTI) is one of the most common infections especially among the population in reproductive age group. This study was designed to isolate, characterize and to determine the antimicrobial susceptibility of uropathogens causing UTI, within the age group of 25-40 yrs attending Govt. Theni Medical College Hospital. The study identified Escherichia coli as the most common cause of UTI with 28% proportion among the positive cultures and most isolates of them were found susceptible to colistin (92.3%), tigecycline (84.3%), meropenam (79.8%) and gentamicin (79.4%).

In this study, a total number of 135 samples were collected and out of them 80 samples were from reproductive tract, 25 feed samples and 30 milk samples from cattle and sheep. Samples collected from reproductive tract of cattle and sheep were subjected to bacteriological and fungal examination for isolation and identification.

The objectives of this study were to find out the bacteria from postpartum dairy cows, determination of their antimicrobial sensitivity, to diagnose subclinical endometritis via endometrial cytology and evaluation of reproductive performance. Uterine discharge from normally parturited cows (n=23) were examined for aerobic bacterial identification and antimicrobial sensitivity at a weekly interval.

Wilt caused by Fusarium oxysporium f. spciceris is a devastating disease of chickpea. It occurs in 2 stages; seedling stage (0-30%) and reproductive stage (0-57%). Annual chickpea yield loss due to Fusarium wilt was estimated to be 10% in India. So, our objective is to control chickpea wilt disease by using Trichoderma based biofilms as an alternative to chemical fungicides. Trichoderma viride is a potential antagonistic fungi which prevents diseases like wilt, brown rot, damping off, charcoal rot etc.
