Brachiopods and forams reduced calcification costs through morphological simplification during mass extinction events [0.03%]
通过形态简化来降低钙化成本使腕足动物和颗石在集群灭绝事件中得以生存
Fengyu Wang,Seth Finnegan,Jacopo Dal Corso et al.
Fengyu Wang et al.
Environmental stressors have exacerbated the collapse of marine ecosystems during mass extinctions. However, the survival strategies of marine species during mass extinctions remain unclear. Here, we investigated morphological evolution of ...
Global variation in vegetation carbon use efficiency inferred from eddy covariance observations [0.03%]
基于涡动相关观测的植被碳利用效率的全球变化规律研究

Xiangzhong Luo et al.
Terrestrial ecosystems have been serving as a strong carbon sink that offsets one-quarter of anthropogenic CO2 emissions. Carbon use efficiency (CUE), the percentage of photosynthesized carbon that is available for biomass production and ot...
Climate drivers and palaeobiogeography of lagerpetids and early pterosaurs [0.03%]
气候驱动及 Lagerpetidae 和早期 Pterosauria 古生物地理学研究
Davide Foffa,Emma M Dunne,Alfio Alessandro Chiarenza et al.
Davide Foffa et al.
The origin of pterosaurs, the first vertebrates to achieve powered flight, is poorly understood, owing to the temporal and morphological gaps that separate them from their closest non-flying relatives, the lagerpetids. Although both groups ...
An episodic burst of massive genomic rearrangements and the origin of non-marine annelids [0.03%]
大规模基因组重排的爆发与非海洋环节动物的起源
Carlos Vargas-Chávez,Lisandra Benítez-Álvarez,Gemma I Martínez-Redondo et al.
Carlos Vargas-Chávez et al.
The genomic basis of cladogenesis and adaptive evolutionary change has intrigued biologists for decades. Here we show that the tectonics of genome evolution in clitellates, a clade composed of most freshwater and all terrestrial species of ...
Vulnerability of soil food webs to chemical pollution and climate change [0.03%]
土壤食物网对化学污染和气候变化的脆弱性
Yu-Rong Liu,Shuhai Wen,Brajesh K Singh et al.
Yu-Rong Liu et al.
Soil food webs are critical for maintaining ecosystem functions but are challenged by various stressors including climate change, habitat destruction and pollution. Although complex multitrophic networks can, in theory, buffer environmental...
Fossil evidence of proboscidean frugivory and its lasting impact on South American ecosystems [0.03%]
古生物化石证据揭示了象形目动物的食果习性及其对南美生态系统的持久影响
Erwin González-Guarda,Andrea P Loayza,Ricardo A Segovia et al.
Erwin González-Guarda et al.
Most megaherbivores in the Americas went extinct around 10,000 years ago, presumably disrupting the long-distance seed dispersal of large, fleshy-fruited plant species. The neotropical anachronism hypothesis, proposed by Janzen and Martin, ...
Three-and-a-half million years of Tibetan Plateau vegetation dynamics in response to climate change [0.03%]
响应气候变化的青藏高原三半百万年植被动态变化
Yan Zhao,Feng Qin,Qiaoyu Cui et al.
Yan Zhao et al.
The Tibetan Plateau supports the largest alpine meadow ecosystem globally. It is considered extremely vulnerable to global warming. Knowledge of past vegetation dynamics under similarly warm climates could shed insights into where the tippi...
Pangolin hunting in southeast Nigeria is motivated more by local meat consumption than international demand for scales [0.03%]
东南亚尼日利亚穿山甲猎捕或为满足本地肉食需求而非国际穿山甲鳞片需求所致
Charles A Emogor,Samuel K Wasser,Lauren Coad et al.
Charles A Emogor et al.
Thousands of species are threatened by overexploitation, often driven by a complex interplay of local and global demand for various products-a dynamic frequently overlooked in wildlife trade policies. African pangolins, regarded as the worl...
Landscape-explicit phylogeography illuminates the ecographic radiation of early archosauromorph reptiles [0.03%]
基于地理的谱系地质学揭示了初龙型 reptile 的生态辐射景观格局
Joseph T Flannery-Sutherland,Armin Elsler,Alexander Farnsworth et al.
Joseph T Flannery-Sutherland et al.
Spatial incompleteness in the fossil record severely diminishes the observed ecological and geographic ranges of clades. The biological processes shaping species distributions and richness through time, however, also operate across geograph...
