Long‐term trends in parasite diversity and infection levels: approaches and patterns
Biological Reviews, EarlyView.ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

Optimized in-solution enrichment of over a million ancient human SNPs
Genome BiologyBackground In-solution hybridization enrichment of genetic markers is a method of choice in paleogenomic studies, where the DNA of interest is generally heavily fragmented and contaminated with environmental DNA, and where the retrieval of genetic data ...

Human tuberculosis - an ancient disease, as elucidated by ancient microbial biomolecules [PDF]
, 2009 Tuberculosis is a major cause of death but infected people with effective immunity may remain healthy for years, suggesting long-term coexistence of host and pathogen.

Biological Reviews, EarlyView.ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Geological processes shaping freshwater biodiversity: a synthesis of global evidence
Biological Reviews, EarlyView.ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Ancient DNA reveals genetic connections between early Di-Qiang and Han Chinese
BMC Evolutionary Biology, 2017 Background Ancient Di-Qiang people once resided in the Ganqing region of China, adjacent to the Central Plain area from where Han Chinese originated. While gene flow between the Di-Qiang and Han Chinese has been proposed, there is no evidence to support ...

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Early cave art and ancient DNA record the origin of European bison
Nature Communications, 2016 The ancestry of the European bison (wisent) remains a mystery. Here, Cooper and colleagues examine ancient DNA from fossil remains of extinct bison, and reveal the wisent originated through the hybridization of the extinct Steppe bison and ancestors of ...

Cytoskeleton, EarlyView.ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.
