Unsteady Flow Patterns between Two Egg-Carton Corrugated Plates

Benjamin GIRÓN-PALOMARES, Abel HERNÁNDEZ-GUERRERO, Ricardo ROMERO-MÉNDEZ & Qiang HE
Unsteady analyses of the flow between two egg-carton corrugated plates were performed. Geometry effects on the flow were as follows: “closed recirculations” shrank downstream the channel and became “open recirculations”. For the 180° egg-carton plates, recirculations were z-symmetric to the channel center. Reynolds number increments favored recirculation growth and flow detachment. Transient development effects were as follows: the steady state was reached faster in waves closer to the channel entrance. As time advanced, spatial flow...

Background: Geographic speciation is a major force in generating biodiversity. However, how genomes diverge over time after geographic isolation has halted gene flow has remained unclear. We examine genome-wide divergence of putatively single-copy orthologous genes (POGs) from transcriptomes in 20 allopatric species/variety pairs from diverse angiosperm clades. Sixteen of these pairs reflect the well-known eastern Asia – eastern North America floristic disjunction; these species have been isolated for different lengths of time, from the Miocene...

Data from: Global fern and lycophyte richness explained: how regional and local factors shape plot richness

Aim To disentangle the influence of environmental factors at different spatial grains (regional and local) on fern and lycophyte species richness and ask how regional and plot-level richness are related to each other. Location Global. Time Period Present. Major Taxa studied Ferns and lycophytes. Methods We explored fern and lycophyte species richness at two spatial grains, regional (hexagonal grid cells of 7666 km2) and plot-level (300–500 m2), in relation to environmental data at regional and...

Data from: Geographic location and food availability offer differing levels of influence on the bacterial communities associated with larval sea urchins

Tyler J. Carrier, Sam Dupont & Adam M. Reitzel
Determining the factors underlying the assembly, structure, and diversity of symbiont communities remains a focal point of animal-microbiome research. Much of these efforts focus on taxonomic variation of microbiota within or between animal populations, but rarely test the proportional impacts of ecological components that may affect animal-associated microbiota. Using larvae from the sea urchin Strongylocentrotus droebachiensis from the Atlantic and Pacific Oceans, we test the hypothesis that, under natural conditions, inter-population differences in the composition...

Data from: Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces

Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men's preference for femininity in women's faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of men's preferences. Using an average femininity preference for each country, we found men's facial femininity preferences correlated positively with the...

Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...
