At the south of its geographical distribution, the fiddler crab Leptuca uruguayensis shows two population spawning events, with more than 65 % of the females being ovigerous. The aim of this study was to assess the energy dynamics in L. uru...
Phalanx morphology in salamanders: A reflection of microhabitat use, life cycle or evolutionary constraints? [0.03%]
环节形态在蝾螈科动物中的体现：是微生境利用、生活史还是进化限制？

California moray eels, Gymnothorax mordax, are benthic predatory residents of southern California kelp forest ecosystems. California morays around Catalina Island move vertically through the water column to feed, exposing them to a wide ran...
Is there a trade-off between sperm production and sexual weaponry in the Amazon River prawn Macrobrachium amazonicum (Heller, 1862)? [0.03%]

The Amazon River prawn Macrobrachium amazonicum shows populations with four well-defined morphotypes in males. Dominant males of morphotypes green claw 1 (GC1) and green claw 2 (GC2) have large bodies and chelipeds and a higher reproductive...
Reproduction and population dynamics of the invasive bivalves Mytilopsis sallei and Isognomon bicolor on the Northeast coast of Brazil [0.03%]
巴西东北海岸入侵双壳类生物Mytilopis sallei和Isognomon bicolor的繁殖及种群动态学研究
Romilda Narciza Mendonça Queiroz,Thelma Lúcia Pereira Dias,Raniele Batista et al.
Romilda Narciza Mendonça Queiroz et al.
Knowing the reproductive biology and population dynamics of invasive species are essential for environmental conservation and protection of native species. The success of these invasive species is directly linked to their reproductive strat...
Form and function of the mantle edge in Protobranchia (Mollusca: Bivalvia) [0.03%]
瓣鳃动物原耳纲软体动物外套膜边缘的形态与功能
Carmen Salas,Juan de Dios Bueno-Pérez,Juan Félix López-Téllez et al.
Carmen Salas et al.
We analyzed, by optical and transmission electron microscopy, the morphology and function of the mantle edge, including the formation of the periostracum, of ten species of protobranchs. Five species from the order Nuculida, four species fr...
Co-occurrence between the presence of epidermal giant cells and alarm chemical cues in tadpole skin homogenates: An ontogenetic and cross-species comparison analysis [0.03%]
蛙皮肤匀浆中表皮巨细胞的存在与警报化学信号共现的个体发生及跨物种比较分析
Lucas David Jungblut,Marilina Raices,Laura Rincón-Camacho et al.
Lucas David Jungblut et al.
In amphibians, intra- or interspecific chemical cues are an important source of information about possible predation risk. In anuran tadpoles, this information causes changes at different levels including behavior, morphology, and growth an...
Shape and ontogenetic changes in otolith of the ocellated icefish (Chionodraco rastrospinosus) from the Bransfield Strait, Antarctic [0.03%]
南极布兰斯菲尔德海峡的斑点冰鱼卵圆耳石形态及其发育变化

Fish otolith shapes record ecological information of fish and are an important tool in taxonomic, phylogenetic, and dietary studies. Shape and ontogenetic variations in the otoliths of ocellated icefish (Chionodraco rastrospinosus) in the B...
Sexual dimorphism and allometry in malacophagus snakes (Dipsadidae: Dipsadinae) [0.03%]
食螺蛇属蛇的两性二态性和异速生长关系研究（游蛇科索吻游蛇亚属）

Marina Meireles Dos Santos
Sexual dimorphism in snakes is generally described in association with body or tail size and scale counts, with relatively few studies addressing intrasexual divergence in the skull. Here, we analyzed sexual dimorphism in the size and shape...
Range-wide variation in grey seal (Halichoerus grypus) skull morphology [0.03%]
灰色 seals(Halichoerus grypus)头骨形态的区域性变化
Anders Galatius,Michelle Strecker Svendsen,Dolores Messer et al.
Anders Galatius et al.
The large interspecific variation in marine mammal skull and dental morphology reflects ecological specialisations to foraging and communication. At the intraspecific level, the drivers of skull shape variation are less well understood, hav...
