Evolutionary biology of lichen symbioses.
Lichens are the symbiotic outcomes of open, interspecies relationships, central to which are a fungus and a phototroph, typically an alga and/or cyanobacterium.

Heart rate as a measure of emotional arousal in evolutionary biology
How individuals interact with their environment and respond to changes is a key area of research in evolutionary biology. A physiological parameter that provides an instant proxy for the activation of the automatic nervous system, and can be measured ...

Elements of divergence in germline determination in closely related species
Summary: Evolutionary transitions are particularly important in development of the germ line, cells which directly impact sexual reproduction. Differences in the primordial germ cells (PGCs) of two sea urchin species were examined here by stage-matched ...

Towards open, reliable, and transparent ecology and evolutionary biology
Unreliable research programmes waste funds, time, and even the lives of the organisms we seek to help and understand. Reducing this waste and increasing the value of scientific evidence require changing the actions of both individual researchers and the ...

Summary: The role of steroid hormone signaling during insect post-embryonic development has been extensively characterized. However, its function during embryonic development is less understood, particularly in short-germ band hemimetabolous insects.

The Extended (Evolutionary) Synthesis Debate: Where Science Meets Philosophy [PDF]
Recent debates between proponents of the modern evolutionary synthesis (the standard model in evolutionary biology) and those of a possible extended synthesis are a good example of the fascinating tangle among empirical, theoretical, and conceptual or ...

FishPIE: A universal phylogenetically informative exon markers set for ray-finned fishes
Summary: Understanding the evolutionary history of the highly diverse ray-finned fishes has been challenging, and the development of more universal primers for phylogenetic analyses may help overcoming these challenges. We developed FishPIE, a nested PCR

Biology and Evolutionary Games [PDF]
This chapter surveys some evolutionary games used in biological sciences. These include the Hawk-Dove game, the Prisoner’s Dilemma, Rock–Paper–Scissors, the war of attrition, the Habitat Selection game, predatorprey games, and signalling games.

Summary: The eukaryotic BBSome is a transport complex within cilia and assembled by chaperonin-like BBS proteins. Recent work indicates nuclear functions for BBS proteins in mammals, but it is unclear how common these are in extant proteins or when they ...
