Reproductive isolation arises during laboratory adaptation to a novel hot environment

Ana Marija Jaksic

Background: Reproductive isolation can result from adaptive processes (e.g., ecological speciation and mutation-order speciation) or stochastic processes such as "system drift" model. Ecological speciation predicts barriers to gene flow between populations ...

Seascape genomics reveals candidate molecular targets of heat stress adaptation in three coral species

Stéphane Joost, Oliver Michele Selmoni

Anomalous heat waves are causing a major decline of hard corals around the world and threatening the persistence of coral reefs. There are, however, reefs that have been exposed to recurrent thermal stress over the years and whose corals appear to have bee ...

Subarray antenna fed by analog beamforming network for 5G picocell applications

Anja Skrivervik

In this paper a subarray fed by an analog beamforming network for 5G picocell applications is proposed. Design requirements are presented taking into account frequency band operation, bandwidth, radiation pattern shape and both, antenna element and transmi ...

Form - function relationships in dragonfly mandibles under an evolutionary perspective

Alessandra Patera

Functional requirements may constrain phenotypic diversification or foster it. For insect mouthparts, the quantification of the relationship between shape and function in an evolutionary framework remained largely unexplored. Here, the question of a functi ...

Turnover and accumulation of genetic diversity across large time-scale cycles of isolation and connection of populations

Séverine Vuilleumier Varisco

Major climatic and geological events but also population history (secondary contacts) have generated cycles of population isolation and connection of long and short periods. Recent empirical and theoretical studies suggest that fast evolutionary processes ...

Evidence Of Adaptation From Ancestral Variation In Young Populations Of Beach Mice

Jeffrey David Jensen

To understand how organisms adapt to novel habitats, which involves both demographic and selective events, we require knowledge of the evolutionary history of populations and also selected alleles. There are still few cases in which the precise mutations ( ...

Differences in the Concept of Fitness Between Artificial Evolution and Natural Selection

Dario Floreano, Pawel Lichocki, Laurent Keller

Evolutionary algorithms were proposed to automatically find solutions to computational problems, much like evolution discovers new adaptive traits. Lately, they have been used to address challenging questions about the evolution of modularity, the genetic ...

Characterizing the Influence of Effective Population Size on the Rate of Adaptation: Gillespie's Darwin Domain

Jeffrey David Jensen

Characterizing the role of effective population size in dictating the rate of adaptive evolution remains a major challenge in evolutionary biology. Depending on the underlying distribution of fitness effects of new mutations, populations of different sizes ...

Circularly polarized aperture coupled stacked patch antenna element for Ka-band

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

This paper presents the design and implementation of a circularly polarized stacked patch antenna element for Ka-band applications. The printed element has been developed to be used in a LEO satellite antenna array. Two circular stacked patches, with air g ...
