Vladimir Mashanov et al.
Background: Echinoderms are a phylum of marine invertebrates with close phylogenetic relationships to chordates. Many members of the phylum Echinodermata are capable of extensive post-traumatic regeneration and life-long ...
A microCT-based atlas of the central nervous system and midgut in sea spiders (Pycnogonida) sheds first light on evolutionary trends at the family level [0.03%]
基于微CT的海蜘蛛中央神经系统和中肠图谱揭示了家族水平上的演化趋势
Karina Frankowski,Katsumi Miyazaki,Georg Brenneis
Karina Frankowski
Background: Pycnogonida (sea spiders) is the sister group of all other extant chelicerates (spiders, scorpions and relatives) and thus represents an important taxon to inform early chelicerate evolution. Notably, phylogen...
Sexual dimorphism in ritualized agonistic behaviour, fighting ability and contest costs of Sus scrofa [0.03%]
家猪Sus scrofa争斗行为、战斗能力及性别差异的研究
Irene Camerlink,Marianne Farish,Gareth Arnott et al.
Irene Camerlink et al.
Background: Sexual selection has driven sexual dimorphism in agonistic behaviour in many species. Agonistic behaviour is fundamentally altered by domestication and captivity, but it is unclear whether ancestral sex differ...
Effects of host state and body condition on parasite infestation of bent-wing bats [0.03%]
宿主状态和身体状况对弯翼蝙蝠寄生虫感染的影响
Yik Ling Tai,Ya-Fu Lee,Yen-Min Kuo et al.
Yik Ling Tai et al.
Background: Ectoparasites inhabit the body surface or outgrowths of hosts and are usually detrimental to host health and wellbeing. Hosts, however, vary in quality and may lead ectoparasites to aggregate on preferred host...
The patterns of co-occurrence variation are explained by the low dependence of bark beetles (Coleoptera: Scolytinae and Platypodinae) on hosts along altitude gradients [0.03%]
基于海拔梯度上松墨天牛等钻蛀害虫对寄主依赖性较低解释其伴生变化模式研究
Fang Luo,Ling-Zeng Meng,Jian Wang et al.
Fang Luo et al.
Background: Separation of biotic and abiotic impacts on species diversity distribution patterns across a significant climatic gradient is a challenge in the study of diversity maintenance mechanisms. The basic task is to ...
Eggs to long-legs: embryonic staging of the harvestman Phalangium opilio (Opiliones), an emerging model arachnid [0.03%]
从蛋到长腿：仓劲螨（Phalangium opilio）的胚胎发育阶段划分及新兴节肢动物模型研究
Guilherme Gainett,Audrey R Crawford,Benjamin C Klementz et al.
Guilherme Gainett et al.
Background: The comparative embryology of Chelicerata has greatly advanced in recent years with the integration of classical studies and genetics, prominently spearheaded by developmental genetic works in spiders. Nonethe...
The interactive effect of ambient temperature and brood size manipulation on nestling body mass in blue tits: an exploratory analysis of a long-term study [0.03%]
雏鸟成长过程中环境温度与巢穴内竞争程度的互作效应：对一个长期研究项目的初步分析
Aneta Arct,Szymon M Drobniak,Anna Dubiec et al.
Aneta Arct et al.
Background: Relatively few studies have examined the interactive effects of ecological factors on physiological responses in wild animals. Nearly all of them have been short-term investigations that did not include experi...
Using natural history to guide supervised machine learning for cryptic species delimitation with genetic data [0.03%]
利用自然历史指导监督机器学习以遗传数据划分伪装物种

Shahan Derkarabetian
The diversity of biological and ecological characteristics of organisms, and the underlying genetic patterns and processes of speciation, makes the development of universally applicable genetic species delimitation methods challenging. Many...
Ontogeny and ecological significance of metabolic rates in sea turtle hatchlings [0.03%]
海龟幼体的代谢率及其生态意义
Christopher R Gatto,T Todd Jones,Brittany Imlach et al.
Christopher R Gatto et al.
Background: Sea turtle hatchlings must avoid numerous predators during dispersal from their nesting beaches to foraging grounds. Hatchlings minimise time spent in predator-dense neritic waters by swimming almost continuou...
Early shape divergence of developmental trajectories in the jaw of galeomorph sharks [0.03%]
冈鱼类鲨鱼下颌表型发育轨迹的早期分异
Faviel A López-Romero,Fidji Berio,Daniel Abed-Navandi et al.
Faviel A López-Romero et al.
Background: The onset of morphological differences between related groups can be tracked at early stages during embryological development. This is expressed in functional traits that start with minor variations, but event...
