In a recent study of the mesotidal Ria Formosa, a coastal lagoon in southern Portugal, water temperature in the channels ranged from 12 C in winter to 27 C in summer and salinity from 13 to 36.5, although much higher values were observed in saltpans. Conditions in the Ria Formosa were not homogeneous despite a large tidal exchange of water; the inner channels of the Ria Formosa were brackish in...

Vertically transmitted symbionts of arthropods have been implicated in several reproductive manipulations of their hosts. These include cytoplasmic incompatibility (CI), parthenogenesis induction in haplodiploid species (PI), feminization and male killing. One symbiont lineage in the alpha-Proteobacteria, Wolbachia, is the only bacterium known to cause all of these effects, and has been thought...

Between 1990 and 1995, the USDA/APHIS National Biological Control Laboratory in Niles, MI, Texas A&M University, and the University of Massachusetts conducted a biological control introduction program against the Asian diaspidid scale insect Unaspis euonymi (Comstock), a pest of woody landscape plants. Two species of predators ( Chilocorus kuwanae Silvestri, Coleop.: Coccinellidae and Cybocepha...

Inorganic carbon availability can limit primary productivity and control species composition of freshwater phytoplankton. This is despite the presence CO2-concentrating mechanisms (CCMs) in some that maximize inorganic uptake. We investigated effects on seasonal distribution, growth rates photosynthesis a diatom, Asterionella formosa, nature its CCM using genomics. In productive lake, frequency...

Male mate choice is critical for understanding the evolution and maintenance of sexual/asexual mating complexes involving sperm-dependent, gynogenetic species. Amazon mollies (Poecilia formosa) require sperm to trigger embryogenesis, but the males (e.g. Poecilia mexicana) do not contribute genes. Males benefit from mating with Amazon mollies, because such matings make males more attractive to c...

The visual pigments of cones and rods in three species of mollies, Poecilia mexicana, Poecilia latipinna and their asexual hybrid Poecilia formosa, were examined using microspectrophotometry. In P. mexicana, populations from extreme photic habitats were used: one population originated from a clear water habitat, one from a milky water habitat and another from a completely dark cave. Ultraviolet...

Aquilegia formosa and pubescens are two closely related species belonging to the columbine genus. Despite their morphological and ecological differences, previous studies have revealed a large degree of intercompatibility, as well as little sequence divergence between these two taxa. We compared the inter- and intraspecific patterns of variation for 9 nuclear loci, and found that the two specie...
