Third generation sequencing methods generate significantly longer reads than those produced using alternative sequencing methods. This provides increased possibilities to better study biodiversity, phylogeography and population genetics. We developed a protocol...

When we look at an oak, we see one organism, despite the fact that each of the estimated 25,808 genes in the oak genome has a unique history. Here I review why the evolutionary history of oaks comprises a variety of phylogenetic histories that trace disparate histories...

Vertebrate bone is composed of three main cell types, the most prominent of which are the osteocytes. These cells are thought to play a fundamental role in bone physiology, however they are entirely absent in most extant species of teleosts, a group that comprises...

We report a nocturnal insect swarm observed aboard the oceanographic ship Cruzeiro do Sul of the Brazilian Navy, while conducting a survey of the Montague guyot (seamount), 389 km distant from the nearest land in the South Atlantic. The insects came from open sea...

Dispersal is a central process in ecology and evolution. It strongly influences the dynamics of spatially structured populations, by affecting population growth rate and local colonization-extinction processes. Dispersal can also influence evolutionary processes...

Neisseria meningitidis (Nm) and N. gonorrhoeae (Ng) are closely related pathogenic bacteria. Using those genes found across 20 Nm and 15 Ng genomes we find that Nm is 7x more diverse than Ng in their combined core genome. Both species have acquired the majority...

The presence of dark pigment spots associated with primary tentacles (or structures derived from them, i.e., rhopalioids) in Staurozoa was recently overlooked in a study on the evolution of cnidarian eyes (defined as a “region made of photoreceptor cells adjacent...

We argue that classic economic games and their more recent extensions should continue to play a role in fieldworkers’ methodological toolkits. Economic games are not replacements for observational and self-report studies of behavior, but rather complements to them:...

The advent of Next Generation Sequencing has reduced sequencing costs and increased genomic projects from a huge amount of organismal taxa, generating an unprecedented amount of genomic datasets publicly available. Often, only a tiny fraction of outstanding relevance...

Much genomic-scale, especially transcriptomic, data on spider phylogeny has accumulated in the last few years. These data have recently been used to investigate the diverse architectures and the origin of spider webs, concluding that the ancestral spider spun no...

Understanding the population dynamics of invasive processes has become a pressing concern in a highly connected world faced with ongoing climate change and increased exotic species introduction. In Chile, the invasive freshwater benthic diatom Didymosphenia geminata...

Ensign wasps (Hymenoptera: Evaniidae) develop as predators of cockroach eggs (Blattodea), have a wide distribution and exhibit numerous interesting biological phenomena. The taxonomy of this lineage has been the subject of several recent, intensive efforts, but...

Relatively few studies have focused on the evolution and development of divergent nervous systems. The salamander clade (Eurycea) from the karst regions of central Texas provide an ideal platform for comparing divergent nervous and sensory systems, since some species...

Primate individuals use a variety of strategies in intergroup encounters, from aggression to tolerance; however, recent focus on the evolution of either warfare or peace has come at the cost of characterizing this variability. We identify evolutionary advantages...
