Observations of historical and recent phytoplankton samples from five hypereutrophic Florida lakes indicate that nitrogen‐fixing cyanobacteria in the genus Cylindrospermopsis Seenayya et Subba RajuExpand
Recreational exposure to microcystins during algal blooms in two California lakes.
It is indicated that recreational activities in water bodies that experience toxin-producing cyanobacterial blooms can generate aerosolized cyanotoxins, making inhalation a potential route of exposure. Expand
Factors controlling seasonal variations in stable isotope composition of particulate organic matter in a softwater eutrophic lake
Weekly water samples were taken to measure stable isotope composition (d13C and d15N) of particulate organic matter (POM) in Lake Wauberg, Florida, from June 1994 to May 1995. The average d13C of POMExpand
Variation in Life History of Land-Locked Lacustrine and Riverine Populations of Galaxias maculatus (Jenyns 1842) in Western Australia
The stable conditions that prevail in the low salinity, cool waters of Moates Lake have fostered an extremely protracted breeding and larval recruitment period (year round) in comparison to limited recruitment in the riverine environments which experience less predictable flow events and water quality.

Characterization of paralytic shellfish toxins from Lyngbya wollei dominated mats collected from two Florida springs
This is the first detailed study confirming PST presence in L. wollei mats in Florida springs and provided evidence supporting the presence of all L.WolleI toxins (LWT 1-6). Expand
Identification of cyanobacterial toxins in Florida's freshwater systems
Monitoring local waters for cyanotoxins in Florida indicates that cyanotoxin production can be a year-round phenomenon in Florida and can occur at levels that may cause ecological and human health problems. Expand
Changes in polyphosphate sedimentation: a response to excessive phosphorus enrichment in a hypereutrophic lake
It is hypothesized that phytoplankton with stored poly-P can remain intact and vi- able for many decades after sedimentation and that sedimented poly- P is not geochemically reactive, thus, it represents bio - logical attenuation that may partially ameliorate the effects of excessive P loading.

Biology of the spotted minnow Galaxias maculatus (Jenyns 1842) (Pisces: Galaxiidae) on the south coast of Western Australia
It is confirmed that, at least throughout most of its range in Western Australia, G. maculatus has established a self-sustaining land-locked reproductive strategy, an adaptive response to changing coastal geomorphology in the Holocene period that restricted ocean access of rivers and their fauna and caused estuaries to become non-tidal.

Helminth parasitism of Galaxias maculatus (Jenyns 1842) in southwestern Australia
The infection of Pseudogobius olorum (Sauvage 1880) by this cestode is reported for the first time in Western Australia as well as two intermittently flowing, saline rivers in southwestern Australia. Expand
Distribution of the spotted minnow (Galaxias maculatus (Jenyns, 1842)) (Teleostei: Galaxiidae) in Western Australia including range extensions and sympatric species
Galaxias maculatus was captured from a number of rivers outside its previously known range. In Western Australia, it was formerly only known from rivers and lakes between the Goodga River (TwoExpand
