| field studies on ozone inactivation of a gymnodinium breve toxin. | water samples were collected from boca ciega bay (st. petersburg) during the april, 1974, red tide that occurred on the florida west coast. the causative agent of this phenomenon was the toxic dinoflagellate, gymnodinium breve. the toxic red tide samples were treated with ozone gas and rendered nonlethal, as measured by mouse injection. | 1975 | 1204593 |
| residue organic mixtures from drinking water show in vitro mutagenic and transforming activity. | indications of possible health effects of residue organics in drinking water have been sought using short-term tests of mutagenic and transforming activity. ten percent or less of the total organic material in drinking water has been identified; the remainder is believed to include thousands of unknown nonvolatile compounds. residual organics were concentrated from drinking water from representative u.s. cities by reverse osmosis followed by liquid-liquid extraction [yielding the reverse osmosis ... | 1978 | 569710 |
| the selective advantage of crypsis in mice. | the light color of mice that inhabit the sandy dunes of florida's coast have served as a textbook example of adaptation for nearly a century, despite the fact that the selective advantage of crypsis has never been directly tested or quantified in nature. using plasticine mouse models of light and dark color, we demonstrate a strong selective advantage for mice that match their local background substrate. further our data suggest that stabilizing selection maintains color matching within a single ... | 2010 | 20163447 |
| the genetic basis of phenotypic convergence in beach mice: similar pigment patterns but different genes. | convergent evolution is a widespread phenomenon seen in diverse organisms inhabiting similar selective environments. however, it is unclear if similar phenotypes are produced by the same or different genes and mutations. here we analyze the molecular mechanisms underlying convergent pigment pattern among subspecies of the beach mouse (peromyscus polionotus) inhabiting the gulf and atlantic coasts of florida. in these two geographic regions, separated by more than 300 km, "beach mice" have lighte ... | 2009 | 18832078 |
| natural selection along an environmental gradient: a classic cline in mouse pigmentation. | we revisited a classic study of morphological variation in the oldfield mouse (peromyscus polionotus) to estimate the strength of selection acting on pigmentation patterns and to identify the underlying genes. we measured 215 specimens collected by francis sumner in the 1920s from eight populations across a 155-km, environmentally variable transect from the white sands of florida's gulf coast to the dark, loamy soil of southeastern alabama. like sumner, we found significant variation among popul ... | 2008 | 18489719 |
| saxitoxin puffer fish poisoning in the united states, with the first report of pyrodinium bahamense as the putative toxin source. | from january 2002 to may 2004, 28 puffer fish poisoning (pfp) cases in florida, new jersey, virginia, and new york were linked to the indian river lagoon (irl) in florida. saxitoxins (stxs) of unknown source were first identified in fillet remnants from a new jersey pfp case in 2002. | 2006 | 17035133 |
| a single amino acid mutation contributes to adaptive beach mouse color pattern. | natural populations of beach mice exhibit a characteristic color pattern, relative to their mainland conspecifics, driven by natural selection for crypsis. we identified a derived, charge-changing amino acid mutation in the melanocortin-1 receptor (mc1r) in beach mice, which decreases receptor function. in genetic crosses, allelic variation at mc1r explains 9.8% to 36.4% of the variation in seven pigmentation traits determining color pattern. the derived mc1r allele is present in florida's gulf ... | 2006 | 16825572 |
| borrelia species in host-seeking ticks and small mammals in northern florida. | the aim of this study was to improve understanding of several factors related to the ecology and environmental risk of borrelia infection in northern florida. small mammals and host-seeking adult ticks were collected at several sites, and specimens were tested for the presence of borrelia species, primarily by pcr amplification. tissues from some vertebrates and ticks were initially cultured in bsk-h medium to isolate spirochetes, but none were recovered. however, comparison of partial flagellin ... | 2004 | 15528699 |
| fitness effects of a selfish gene (the mus t complex) are revealed in an ecological context. | in wild house mice, genes linked to the t transmission distortion complex cause meiotic drive by sabotaging wild-type gametes. the t complex is consequently inherited at frequencies higher than 90%. yet, for unclear reasons, in wild mouse populations this selfish dna is found at frequencies much lower than expected. here, we examine selection on the t complex in 10 seminatural populations of wild mice based on data from 234 founders and nearly 2000 progeny. eight of the 10 populations decreased ... | 2004 | 15266980 |
