The moa (Dinornithiformes: Aves) are an extinct group of ratites from the North and South Islands of New Zealand. The ancestors of both the moa and the kiwi were isolated from other Gondwanan fauna as much as 80 million years ago and evolve...
Reproductive hormones modify reception of species-typical communication signals in a female anuran [0.03%]
生殖激素可改变蛙类雄性信号在雌性身上的作用效果

In many vertebrates, the production and reception of species-typical courtship signals occurs when gonadotropin and gonadal hormone levels are elevated. These hormones may modify sensory processing in the signal receiver in a way that enhan...
Photoperiod-independent hypothalamic regulation of luteinizing hormone secretion in a free-living Sonoran desert bird, the Rufous-winged Sparrow (Aimophila carpalis) [0.03%]
光照周期独立的下丘脑调节索诺兰沙漠生活着的锈翅小鹀(Aimophila carpalis)促黄体生成激素分泌的作用机制研究

Thomas W Small et al.
We investigated the regulation of luteinizing hormone (LH) in the male Rufous-winged Sparrow,Aimophila carpalis, a resident of the Sonoran desert that breeds after irregular summer rains. Although the testes develop in March due to increasi...

A K Starosciak et al.
The startle response of Pantodon buchholzi, the African butterfly fish, is a complete or incomplete ballistic jump resulting from abduction of the pectoral fins. This study analyzed the neuromuscular basis for such a jump by recording in vi...
Evolution of brain size in the Palaeognath lineage, with an emphasis on new zealand ratites [0.03%]
平胸龚纲脑容量演化研究——以新西兰鹤鸟目为主

Jeremy R Corfield et al.
Brain size in vertebrates varies principally with body size. Although many studies have examined the variation of brain size in birds, there is little information on Palaeognaths, which include the ratite lineage of kiwi, emu, ostrich and e...
Morphology and evolutionary biology of the dolphin (Delphinus sp.) brain--MR imaging and conventional histology [0.03%]

H H A Oelschläger et al.
Whole brains of the common dolphin (Delphinus delphis) were studied using magnetic resonance imaging (MRI) in parallel with conventional histology. One formalin-fixed brain was documented with a Siemens Trio Magnetic Resonance scanner and c...

Aggression causes major health and social problems and constitutes a central problem in several psychiatric disorders. There is a close relationship between the display of aggression and stress coping strategies. In order to gain more insig...
Stress, aggression, and puberty: neuroendocrine correlates of the development of agonistic behavior in golden hamsters [0.03%]
压力、攻击行为和青春期:金仓鼠争斗行为发展相关的神经内分泌反应
