| temephos distribution and persistence in a southwest florida salt marsh community. | the distribution and persistence of the mosquito larvicide temephos was monitored throughout an intertidal salt marsh community in southwest florida following routine aerial applications of abate 4-e (43% temephos) from 1988 through 1993. temephos was found to be more highly concentrated in the surface water microlayer than in mid-depth water, exhibiting a mean of 330 micrograms/liter at the surface and 12 micrograms/liter at mid-depth from 1 fl. oz./acre applications and 120 micrograms/liter in ... | 1996 | 9046469 |
| spatially explicit assessment of estuarine fish after deepwater horizon oil spill: trade-off in complexity and parsimony. | evaluating long-term contaminant effects on wildlife populations depends on spatial information about habitat quality, heterogeneity in contaminant exposure, and sensitivities and distributions of species integrated into a systems modeling approach. rarely is this information readily available, making it difficult to determine the applicability of realistic models to quantify population-level risks. to evaluate the trade-offs between data demands and increased specificity of spatially explicit m ... | 2016 | 27755711 |
| evaluation of pre- and post-zygotic mating barriers, hybrid fitness and phylogenetic relationship between cyprinodon variegatus variegatus and cyprinodon variegatus hubbsi (cyprinodontiformes, teleostei). | the euryhaline fish cyprinodon variegatus variegatus (cvv) is capable of tolerating ambient salinities ranging from 0.3 to 167 g l(-1) , but incapable of long-term survival in freshwater (< 2 mm na(+) ). however, a population of this species, now designated as a subspecies (cyprinodon variegatus hubbsi; cvh), has been isolated in several freshwater (0.4-1 mm na(+) ) lakes in central florida for the past ~150 ky. we previously demonstrated that cvh has a significantly higher affinity for na(+) up ... | 2013 | 23480788 |
| effects of salinity on native estuarine fish species in south florida. | variable and high salinities have been identified as key stressors in florida bay. the comprehensive everglades restoration plan (cerp) includes water redistribution projects that are intended to restore natural freshwater flows to northeastern florida bay. the present salinity regimes in the area, which span from hypo- to hypersaline, will be altered as a result of these actions. this research examined biological performance measures (i.e., growth and survival) of estuarine fish under varying s ... | 2008 | 18642076 |
| fate and toxicity of temephos applied to an intertidal mangrove community. | the distribution, persistence, and toxicity of the mosquito larvicide temephos was monitored following aerial applications to an intertidal mangrove community in lee county, florida. the amount of temephos penetrating to the mangrove floor ranged from 15 to 70% of the amount entering the upper leaf canopy, with 50-60% of that applied remaining on the mangrove leaves. rainfall caused an additional influx of temephos from the leaves to the mangrove floor. residues were detected in intertidal water ... | 1989 | 2482341 |
