Animal coloration serves various signaling and non-signaling functions. In damselflies and dragonflies (Odonata), such colors may not only play photoprotective and/or thermoregulatory roles but also serve as visual signals during courtship ...
Biotic factors as key determinants for ovarian and oothecal developmental plasticity of a tortoise beetle [0.03%]
生物因素是甲虫卵发育的关键决定因素

Ruchita Shivprakash Tiwari et al.
Ovarian development in r-selected species is a highly dynamic process widely studied in various insect groups. An array of biotic and abiotic factors may influence it. So, the present investigation was to evaluate the impact of a female's a...
Seasonal dimorphism as an expression of sexual dimorphism: Influence of gonad maturity on the body shape of a rocky intertidal polyplacophoran [0.03%]
生殖二型的季节表现形式:卵巢成熟对一种岩间多板纲动物体形的影响

Brenda Paola Ramirez-Santana et al.
Seasonal dimorphism in the body shape of marine invertebrates has been poorly explored compared to vertebrates. We aim to investigate through traditional (body length/width ratio, dorsal elevation ratio and angle of elevation) and geometric...
Can all snakes swim? A review of the evidence and testing species across phylogeny and morphological diversity [0.03%]
会游泳的蛇类遍布整个谱系吗?对其证据进行回顾及对形态多样性种类的测试研究

Guillaume Fosseries et al.
Alternative hypotheses suggest that the reptiles at the origin of snakes were primarily either burrowing, terrestrial or marine. It is possible that the ability to swim varies between the major snake lineages and lifestyles; for example, th...
The hind limb of Octodontidae (Rodentia, Mammalia): Functional implications for substrate preferences [0.03%]

Octodontids are South American caviomorph rodents endemic to mesic and arid biomes displaying a wide range of substrate preferences, from terrestrial to subterranean habits. However, the hind limb morphology of these rodents remain relative...
Kinematics of elongate harvestmen chelicerae: Comparative range of motion analyses in extant Ischyropsalis (Dyspnoi, Opiliones) [0.03%]
现生长腿马陆蟹蛛螯器的运动学:Ischyropsalis属(Dyspnoi,Opiliones)的比较活动范围分析

Michel Schmidt et al.
Chelicerae, the mouthparts of chelicerates, are essential for food processing. Particularly within harvestmen (Opiliones), some species have greatly elongated their tripartite chelicerae and utilize them for mating behavior, defense, and pr...

The liver, a crucial organ for metabolic processes, has a generally uniform histological structure across amphibian taxa. However, ontogenetic changes, particularly those related to biphasic life cycle and metamorphosis, are less documented...
External morphology and growth patterns of larvae and juveniles of Bryconops gracilis (Characiformes, Iguanodectidae) from Amazon basin [0.03%]
