Stochastic birth-death processes are described as continuous-time Markov processes in models of population dynamics. A system of in nite, coupled ordinary diferential equations (the so- called master equation) describes ...

Birds living in riverine environments may show weak population structure because high dispersal abilities required to track habitat dynamics can result in gene flow over broad spatial scales. Alternatively, the configuration ...

Satellite cells are tissue-specific stem cells primarily responsible for the regenerative capacity of skeletal muscle. Satellite cell function and maintenance are regulated by extrinsic and intrinsic mechanisms, including ...

Introduction: Lung cancer is the most lethal and incidental type of cancer in the world. Several benign lung diseases may mimic lung carcinoma in its clinical and radiological presentation, which makes the differential ...

This study proposes a delay-coupled system based on the logistic equation that models the interaction of a population with its varying environment. The integro-diferential equations of the model are presented in terms of ...

Bufo spinulosus es un anfibio que se distribuye ampliamente en los Andes Peruano-Boliviano y Argentino, mientras que en Chile se pueden encontrar poblaciones distribuidas en el Norte Grande y Centro del país, presentando ...

The study of landscape features that influence genetic structure of wild populations can help us understand the first steps of biological divergence. Populations diverge when there is restriction to gene flow, which can ...
