It has been reported that endocrine disrupter compounds (EDCs) interfere with the endocrine system, mimicking the action of sex steroid hormones in different species of mollusks. Prosobranchs are frequently used as a reliable bioindicator t...
Gonadal sex differentiation in frogs: how testes become shorter than ovaries [0.03%]

Testis differentiation in anuran amphibians is the result of two opposing processes: degeneration of the distal part, and development of the proximal part, which becomes a functional male gonad. Undifferentiated gonad differentiates directl...

Among mammals, the similarity in body temperature indicates that body size differences in heat loss must match the body size differences in heat production. This study tested the possibility that body surface temperature (Tbs), responsible ...
Comparative study of the pheromone-manufacturing femoral glands in two sympatric species of lacertid lizards (Acanthodactylus) [0.03%]

Rafael Ernesto Balen et al.
Two populations of Hollandichthys multifasciatus from headwaters of adjacent river coastal basins in Paraná state, southern Brazil, were cytogenetically studied in order to evaluate intraspecific divergences. Both populations presented 2n ...
Oriental orchid (Cymbidium floribundum) attracts the Japanese honeybee (Apis cerana japonica) with a mixture of 3-hydroxyoctanoic acid and 10-hydroxy- (E)-2-decenoic acid [0.03%]
三羟基辛酸和反式10-羟基二十碳烯酸混合物吸引日本蜜蜂（Apis cerana japonica）到春兰(Cymbidium floribundum)花朵上采蜜

Michio Sugahara et al.
The flower of the oriental orchid Cymbidium floribundum is known to attract the Japanese honeybee Apis cerana japonica. This effect is observed not only in workers but also drones and queens; that is, it attracts even swarming and abscondin...
Reproduction and morphology of the common lizard (Zootoca vivipara) from montane populations in Slovakia [0.03%]

The western Pacific lancelet, once recognized as a monospecies, Branchiostoma belcheri, is a frequently used model in evolutionary and developmental studies, and researchers usually collect samples from the field without consideration of sp...
Two patterns of parasitic male mating behaviors and their reproductive success in Japanese medaka, Oryzias latipes [0.03%]
斑马鱼体内两种寄生雄性交配行为及其繁殖成功案例研究

Yasunori Koya et al.
We found two patterns of parasitic mating behaviors by male in Japanese medaka, Oryzias latipes, in the spawning by one female and two males in the aquarium condition. In the first type of parasitic mating behavior, the unpaired male would ...
Somatosensation, echolocation, and underwater sniffing: adaptations allow mammals without traditional olfactory capabilities to forage for food underwater [0.03%]
躯体感觉、回声定位和水下嗅探：适应性使没有传统嗅觉能力的哺乳动物能够潜入水中觅食
Sarah Marriott,Emily Cowan,Jacob Cohen et al.
Sarah Marriott et al.
Animals rely mainly on olfaction to locate and track food sources. However, mammals that have evolved to live partially or fully underwater are unable to use traditional olfaction in the foraging process. These animals have subsequently dev...
