Was Prometheus Unbound by Chance? Risk, Diversification, and Growth

Journal of Political Economy, 1997
This paper offers a theory of development that links the degree of market incompleteness to capital accumulation and growth. At early stages of development, the presence projects limits the degree of risk spreading (diversification) that the economy can ...

A dynamic continental moisture gradient drove Amazonian bird diversification

Science Advances, 2019
Diversification of Amazon birds led by climate stability: lineages originated in the wetter west and dispersed into the drier east. The Amazon is the primary source of Neotropical diversity and a nexus for discussions on processes that drive biotic ...

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

Molecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

Evolution of microgastropods (Ellobioidea, Carychiidae): integrating taxonomic, phylogenetic and evolutionary hypotheses [PDF]

, 2013
BACKGROUND: Current biodiversity patterns are considered largely the result of past climatic and tectonic changes. In an integrative approach, we combine taxonomic and phylogenetic hypotheses to analyze temporal and geographic diversification of epigean (

Tip rates, phylogenies and diversification: What are we estimating, and how good are the estimates?

Methods in Ecology and Evolution, 2019
Species‐specific diversification rates, or ‘tip rates’, can be computed quickly from phylogenies and are widely used to study diversification rate variation in relation to geography, ecology and phenotypes. These tip rates provide a number of theoretical
