Spatial and temporal environmental variation influences evolutionary processes such as divergence among populations and species. Here, we investigate the patterns of niche evolution for the Louisiana irises as well as understanding the phyl...
Connecting the dots: avian eggshell pigmentation, female condition and paternal provisioning effort [0.03%]
牵线搭桥：鸟类蛋壳色素沉着、雌性体质和雄性抚育努力程度之间的关系

Kara E Hodges et al.
Differences in avian eggshell pigmentation could be an honest signal of female quality that males use to inform their nestling provisioning effort. We investigated whether among-individual variation in protoporphyrin-based eggshell pigmenta...
A comparative study of the distribution and density of stomata in the British flora [0.03%]
英国植物 stomata 的分布与密集度比较研究
H J Peat,A H Fitter
H J Peat
The distribution of stomata over both leaf surfaces may affect both the photosynthetic rate and water use efficiency of species, implying that species with different photosynthetic and water requirements may also have different stomatal dis...
Phylogenetic relationships and molecular evolution in uropeltid snakes (Serpentes: Uropeltidae): allozymes and albumin immunology [0.03%]
叶蛇科蛇类的系统发育关系及分子进化：allozyme和血清免疫学研究
John E Cadle,Herbert C Dessauer,Carl Gans et al.
John E Cadle et al.
Multilocus electrophoretic methods and microcomplement fixation comparisons of serum albumin are used to assess phylogenetic relationships among species of uropeltid snakes, to infer aspects of their population biology and biogeography, and...

The outgroup method is widely used to root phylogenetic trees. An accurate root indication, however, strongly depends on the availability of a proper outgroup. An alternate rooting method is the midpoint rooting (MPR). In this case, the roo...
The Apennines as a cryptic Pleistocene refugium of the bark beetle Pityogenes chalcographus (Coleoptera: Curculionidae) [0.03%]
意大利亚平宁山脉可能是拟皱皮蠢产卵的隐匿地点（鞘翅目，谷蠹族）
Martin Schebeck,Hannes Schuler,Birgit Einramhof et al.
Martin Schebeck et al.
The Apennine Mountains in Italy are an important biogeographical region and of particular interest in phylogeographical research, because they have been a refugium during Pleistocene glaciation events for numerous European species. We perfo...
Strong, but incomplete, mate choice discrimination between two closely related species of paper wasp [0.03%]
两种密切相关的大黄蜂纸状巢的交配选择歧视强烈但不完整
Sara E Miller,Andrew W Legan,Zoe A Flores et al.
Sara E Miller et al.
Paper wasps (genus Polistes) are one of the most species-rich genera of social insect. Prior studies have found that male coloration, male colour pattern, territory choice and female caste are potential drivers of intraspecific mate choice ...
Biparental care is predominant and beneficial to parents in the burying beetle Nicrophorus orbicollis (Coleoptera: Silphidae) [0.03%]
双亲抚育在宽胫地甲（Nicrophorus orbicollis）中占优势且对父母有益
Kyle M Benowitz,Allen J Moore
Kyle M Benowitz
Parenting strategies can be flexible within a species, and may have varying fitness effects. Understanding this flexibility and its fitness consequences is important for understanding why parenting strategies evolve. Here, we investigate th...
Strong between-site variation in New Caledonian crows' use of hook-tool-making materials [0.03%]
新喀鸦制造钩工具材料使用的站点间差异明显
James J H St Clair,Barbara C Klump,Jessica E M van der Wal et al.
James J H St Clair et al.
Functional tool use requires the selection of appropriate raw materials. New Caledonian crows Corvus moneduloides are known for their extraordinary tool-making behaviour, including the crafting of hooked stick tools from branched vegetation...
Temporal and spatial mosaics: deep host association and shallow geographic drivers shape genetic structure in a widespread pinworm, Rauschtineria eutamii [0.03%]
时空镶嵌体：深入的宿主关联和浅层的地理驱动因素塑造了广泛分布的小杆目线虫Rauschtineria eutamii的遗传结构
Kayce C Bell,Kendall L Calhoun,Eric P Hoberg et al.
Kayce C Bell et al.
Climate and host demographic cycling often shape both parasite genetic diversity and host distributions, processes that transcend a history of strict host-parasite association. We explored host associations and histories based on an evaluat...
