Animals that communicate acoustically must compete for acoustic space in order to convey their signals effectively. Tropical rainforest birds live an extremely diverse community consisting of other birds, mammals, frogs, and many insects. Insects are notable often producing continuous bands sound energy at constant frequencies, which vary between species across habitats. We examined how green hylia (Hylia prasina) song frequencies correlate insect-generated spectral profiles ambient noise....
Abstract Reptiles display considerable diversity in reproductive behavior, making them great models to study the neuroendocrine control of behavior. Many reptile species are seasonally breeding, such that they become reproductively active during their breeding season and regress a nonreproductive state nonbreeding season, with this transition often prompted by environmental cues. In review, we will focus on summarizing neural mechanisms controlling Three major areas brain involved behavior:...
Geographic isolation in rainforest refugia and local adaptation to ecological gradients may both be important drivers of evolutionary diversification. However, their relative importance the underlying mechanisms these processes remain poorly understood because few empirical studies address putative a single system. A key question is what extent divergence signals that are mate species recognition driven by or divergent selection across gradients? We studied little greenbul, Andropadus...

Behçet's disease is known to be strongly associated with HLA-B51 in many different ethnic groups. Recently, it was suggested that MIC-A (major histocompatibility complex class I related gene A) the pathogenic after strong association found between A6 allele of transmembrane region and Japanese Greek patients, although patients this due linkage disequilibrium HLA-B51.To investigate microsatellite polymorphism Arab non-Ashkenazi Jewish (NAJ) Israel, determine whether occurs these groups...
Neural testosterone metabolism, particularly the synthesis of oestradiol (E(2)) via aromatase enzyme, is important for sexual behaviours in many vertebrates. In green anole lizards, E(2) metabolised from facilitates female receptivity and increases motivation males. Testosterone treatment activity whole brain homogenates gonadectomised male, but not female, anoles, which an effect limited to breeding season (BS). To investigate potential local effects this enzyme reproductive behaviour, we...
Seasonally breeding songbirds exhibit pronounced annual changes in song behavior, and the morphology physiology of telencephalic neural circuit underlying production learned song. Each season, new adult-born neurons are added to pallial nucleus HVC response seasonal steroid hormone levels, send long axonal projections their target nucleus, robust arcopallium (RA). We investigated role that adult neurogenesis plays reconstruction this circuit. labeled newborn with BrdU, RA-projecting...
A comparative study of lactogen receptors in lactogenic hormone-dependent (Nb2-11C) and independent (Nb2-SP) rat lymphoma cell lines revealed no significant differences their binding structural characteristics. The affinity for human growth hormone (hGH) ovine prolactin is identical (Kd = 1.3 X 10(-10) M). Exposure to hGH results a rapid receptor down-regulation. This process faster Nb2-SP cells, however, similar levels are reached within 3 h. Affinity labeling 2 major species (Mr 75,000...
The 5α-reductase (5αR) enzyme converts testosterone to 5α-dihydrotestosterone. This local metabolism within the brain is important for full expression of male sexual behavior in many species, including green anole lizards. Two isozymes 5αR exist and little known about their specific distributions. We conducted situ hybridization both intact female brains during breeding (BS) non-breeding (NBS) seasons. 5αR1 mRNA was only detected brainstem, while 5αR2 expressed areas throughout brain. As our...
Our goal in the current study was to further investigate late neurodevelopmental hypothesis of schizophrenia by examining cross-sectional, age-related changes cognitive function among young adult (a) siblings individuals with ( n = 66), (b) healthy control subjects 77), and (c) 77). All participated a battery tasks four domains: verbal IQ, working memory, episodic executive function. We found significant group differences relationships between age performance memory similar patterns for IQ....

Abstract The costs of reproduction, involving demands associated with both current and future reproductive efforts, may place a substantial burden on females. However, animals minimize these by modifying their behavior across the cycle. We examined effects load three types (locomotion, foraging, social displays) in green anole lizards ( Anolis carolinensis ) comparing egg, follicle, oviduct mass volume field observational data. found that female locomotor display behaviors decreased as...
