“Super-blooms” of cyanobacteria that produce potent and environmentally persistent biotoxins (microcystins) are an emerging global health issue in freshwater habitats. Monitoring the marine environment for secondary impacts has been minimal, although microcystin-contaminated is known to be entering ecosystems. Here we confirm deaths mammals from microcystin intoxication provide evidence implicating land-sea flow with trophic transfer through invertebrates as most likely route exposure. This...
Invasive species represent a significant threat to global biodiversity and substantial economic burden. Burmese pythons, giant constricting snakes native Asia, now are found throughout much of southern Florida, including all Everglades National Park (ENP). Pythons have increased dramatically in both abundance geographic range since 2000 consume wide variety mammals birds. Here we report severe apparent declines mammal populations that coincide temporally spatially with the proliferation...
In November-December 2007 a widespread seabird mortality event occurred in Monterey Bay, California, USA, coincident with massive red tide caused by the dinoflagellate Akashiwo sanguinea. Affected birds had slimy yellow-green material on their feathers, which were saturated water, and they severely hypothermic. We determined that foam containing surfactant-like proteins, derived from organic matter of tide, coated feathers neutralized natural water repellency insulation. No evidence exposure...
ABSTRACT Aim Visual probe tasks are often used to measure attentional bias (AB) towards alcohol‐related images in drinkers, but little is known about the effect of properties this task: specifically, image complexity. Methods AB was examined a group adult drinkers ( n = 25). Two measures were obtained from modified visual task. First, traditional dot detection task measured based on their reaction times probes replacing neutral and images. Secondly, an eye‐tracking applied directly assess...
Burmese pythons ( Python molurus bivittatus ) are native to southeastern Asia, however, there is an established invasive population inhabiting much of southern Florida throughout the Greater Everglades Ecosystem. Pythons have severely impacted species and ecosystems in represent one most intractable invasive-species management issues across globe. The difficulty stems from a unique combination inaccessible habitat cryptic resilient nature that thrive subtropical environment Florida,...
Although protected for nearly a century, California's sea otters have been slow to recover, in part due exposure fecally-associated protozoal pathogens like Toxoplasma gondii and Sarcocystis neurona.However, potential impacts from fecal bacteria not systematically explored.Using selective media, we examined feces live dead California specific enteric bacterial (Campylobacter, Salmonella, Clostridium perfringens, C. difficile Escherichia coli O157:H7), endemic the marine environment (Vibrio...
The value of Bacteroidales genetic markers and fecal indicator bacteria (FIB) to predict the occurrence waterborne pathogens was evaluated in ambient waters along central California coast. host-specific quantitative PCR (qPCR) used quantify water provide insights into contributing host sources. Over 140 surface samples from 10 major rivers estuaries within Monterey Bay region were tested over 14 months with four Bacteroidales-specific assays (universal, human, dog, cow), three FIB (total...

Insulin secretion and clearance were studied in 2 groups of 7 normal subjects who each received 25, 50, 100 g glucose either orally or intravenously (iv) on separate occasions. rates calculated during a 1-h base line for 5 h after administration from two-compartmental analysis peripheral C-peptide concentrations using individual kinetic parameters derived iv bolus injections biosynthetic human C-peptide. Incremental areas oral increased as function the dose (P = 0.0001). insulin with...
Aims: Considerable laboratory research indicates that moderate doses of alcohol impair a broad range skilled activities related to driving performance in young adults. Although studies show the intensity impairment is generally dependent on blood concentration, some reviews this literature suggest women might be more sensitive impairing effects than men. The present study tested hypothesis. Methods: Drawing data from previous experiments our laboratory, we compared men and terms degree which...
Burmese pythons (Python bivittatus) have demonstrated prolific spread and low detectability within their invasive range in Florida, USA. Consequently, programs exist which incentivize contractors to remove pythons. While surveying, collect data on search effort python captures. We examined from South Florida Water Management District's Python Elimination Program determine the effect of operational environmental covariates two measures survey outcome: success (i.e., probability removing at...
Reduced executive cognitive ability is associated with alcohol dependence (AD) and other comorbid externalizing disorders. Working memory capacity, short-term memory, conditional associative learning, intelligence were assessed in a sample (N = 477) variation lifetime histories of problems (conduct disorder, adult antisocial behavior, substance problems); this included subsample (n 285) Diagnostic Statistical Manual Mental Disorders (4th ed.; American Psychiatric Association, 1994) diagnosis...
People, domestic animals, and wildlife are all exposed to numerous environmental threats, including harmful algal blooms (HABs). However, because animals exhibit wide variations in diet, land use biology, they often more frequently or heavily HAB toxins than people occupying the same habitat, making them sentinels for human exposures. Historically, we have taken advantage of unique physiological characteristics such as sensitivity canaries carbon monoxide, quickly recognize threats help...
Questions of recurrence and inadequacy follow-up length persist regarding endoscopic treatment colloid cysts. In this retrospective review, we report our long-term during a 13-year period in 35 patients who underwent resection cysts.The 19 males 16 females (age range 14 to 58 years, mean 35.9 years) had symptomatic cysts that ranged size from 5 mm 4 cm the 1991 2004.Of 2 developed recurrences at 5.9 years 4.3 (1 6 mm, respectively) both remain asymptomatic. The rate late asymptomatic series...
Alcohol can disrupt goal-directed behavior by impairing the ability to inhibit attentional shifts toward salient but goal-irrelevant stimuli. Individuals who are highly sensitive this effect of drug may be at increased risk for problematic drinking, especially among those whose attention is drawn alcohol-related cues in environment (i.e., bias). The current study examined acute alcohol on inhibitory mechanisms control a group healthy social drinkers. We then whether sensitivity disinhibiting...
Harmful algal blooms produce toxins that bioaccumulate in the food web and adversely affect humans, animals, entire marine ecosystems. Blooms of diatom Pseudo-nitzschia can domoic acid (DA), a toxin most commonly causes neurological disease endothermic with cardiovascular effects were first recognized southern sea otters. Over last 20 years, DA toxicosis has caused significant morbidity mortality mammals seabirds along west coast USA. Identifying exposure been limited to detection biological...
