Colonization of new environments can lead to population bottlenecks and rapid phenotypic evolution that could be due to neutral and selective processes. Exotic populations of the bull-headed dung beetle (Onthophagus taurus) have differentia...
Evolutionary rescue via transgenerational plasticity: Evidence and implications for conservation [0.03%]

When a population experiences severe stress from a changing environment, evolution by natural selection can prevent its extinction, a process dubbed "evolutionary rescue." However, evolution may be unable to track the sort of rapid environm...

Established model systems in the flowering plants have greatly advanced our understanding of plant developmental biology, facilitating in turn its investigation across diverse land plants. The reliance on a limited number of model organisms...
Tergal and pleural wing-related tissues in the German cockroach and their implication to the evolutionary origin of insect wings [0.03%]
美洲蟑螂的翅芽和相关体壁褶皱结构及其对于昆虫翅膀进化起源的启示

The acquisition of wings has facilitated the massive evolutionary success of pterygotes (winged insects), which now make up nearly three-quarters of described metazoans. However, our understanding of how this crucial structure has evolved r...
Comparative transcriptomics of a monocotyledonous geophyte reveals shared molecular mechanisms of underground storage organ formation [0.03%]
单子叶地被植物比较转录组学揭示了地下贮藏器官形成的共同分子机制

Many species from across the vascular plant tree-of-life have modified standard plant tissues into tubers, bulbs, corms, and other underground storage organs (USOs), unique innovations which allow these plants to retreat underground. Our ab...
Evolutionary modification of gastrulation in Parvulastra exigua, an asterinid seastar with holobenthic lecithotrophic development [0.03%]
隐胚海星Parvulastra exigua具卵胎生发育方式的原肠胚形成之演化改造机制探讨

Gastrulation is a fundamental morphogenetic process in development. In echinoderms with ancestral-type development through feeding larvae, gastrulation involves radially symmetrical invagination of cells around the blastopore. Gastrulation ...
Changes in Nkx2.1, Sox2, Bmp4, and Bmp16 expression underlying the lung-to-gas bladder evolutionary transition in ray-finned fishes [0.03%]

The key to understanding the evolutionary origin and modification of phenotypic traits is revealing the responsible underlying developmental genetic mechanisms. An important organismal trait of ray-finned fishes is the gas bladder, an air-f...
Maternal and larval niche construction interact to shape development, survival, and population divergence in the dung beetle Onthophagus taurus [0.03%]

DELLA proteins are master growth regulators that repress responses to a group of plant growth hormones called gibberellins (GAs). Manipulation of DELLA function and signaling was instrumental in the development of high-yielding crop varieti...
Comparative analysis of corolla tube development across three closely related Mimulus species with different pollination syndromes [0.03%]

Fusion of petals to form a corolla tube is considered a key innovation contributing to the diversification of many flowering plant lineages. Corolla tube length often varies dramatically among species and is a major determinant of pollinato...
