, 2018 The Quaternary is synonymous with extensive glaciation of Earth's mid- and high latitudes. Although there were local precursors, significant glaciation began in the Oligocene in eastern Antarctica. It was followed by glaciation in mountain areas through the Miocene (in Alaska, Greenland, Iceland, and Patagonia), later in the Pliocene (e.g., in the Alps,

Developmental Dynamics, EarlyView.Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

Environmental and geomorphological drivers of frog diversity on islands worldwide
Ecography, EarlyView.Island biogeography models primarily rely on island physical features and isolation to explain their biodiversity patterns. While newer models have incorporated functional traits to understand plant distribution, few empirical studies have tried to disentangle geometric constraints from niche‐based processes to predict multiple diversity facets of ...

A Biogeographic History of the Plains Bison Focusing on Population and Range Dynamics [PDF]
, 2015 Early bison originated in Asia and migrated to North America by means of the Bering Land Bridge, which opened around 600,000 years ago. Just after the Wisconsin glaciation (11, 700 years ago), there were two allopatric species of bison residing in North ...

Cross‐scale interactions mediate local drivers of nonnative species richness
Ecography, EarlyView.Many well‐supported hypotheses seek to explain drivers of nonnative species richness across spatial scales, but evidence for common patterns among regions and taxa remains inconclusive. This study investigates why consistent patterns are elusive by estimating and assessing cross‐scale interactions, wherein large‐scale factors contextualize patterns ...

Glacial cycles promote greater dispersal, which can help explain larger clutch sizes, in north temperate birds [PDF]
, 2009 Earth’s glacial history and patterns in the life history traits of the planet’s avifauna suggest the following interpretations of how recent geological history has affected these key characteristics of the biota: 1) Increased colonizing ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A biomass‐based transparent bamboo composite doped with europium efficiently converts UV light into photosynthetically active red light, significantly enhancing plant growth and providing a sustainable alternative to petroleum‐based agricultural films. The rational design of sustainable light‐conversion agricultural materials is critical for enhancing ...

European Journal of Organic Chemistry, EarlyView.Intramolecular cyclization to quench an in situ reduction‐generated azaquinone methide is a strategy that could be used for late‐stage heterocycle synthesis. Herein, synthetically accessible 4‐nitrobenzyl alcohols with a nucleophilic handle adjacent to the benzyl alcohol group are reduced under mild conditions to afford six‐ and seven‐membered ...

Evidence for glaciation in Elysium [PDF]
It is suggested that certain landforms in the Elysium region of Mars provide strong evidence for glaciation. Landscapes related to subglacial volcanism suggest that ice was a primary agent in the development of ...
