In October 2009, during a Karenia brevis red tide along the Texas coast, millions of dead fish washed ashore along the 113-km length of Padre Island National Seashore (PAIS). Between November 2009 and January 2010, at least 12 coyotes (Canis latrans) and three domestic dogs (Canis familiaris) died or were euthanized at PAIS or local veterinary clinics because of illness suspected to be related to the red tide. Another red tide event occurred during autumn 2011 and, although fewer dead fish were observed relative to the 2009 event, coyotes again were affected. Staff at PAIS submitted carcasses of four coyotes and one domestic dog from November 2009 to February 2010 and six coyotes from October to November 2011 for necropsy and ancillary testing. High levels of brevetoxins (PbTxs) were measured by enzyme-linked immunosorbent assay in seven of the coyotes and the dog, with concentrations up to 634 ng PbTx-3 eq/g in stomach contents, 545 ng PbTx-3 eq/g in liver, 195 ng PbTx-3 eq/g in kidney, and 106 ng PbTx-3 eq/mL in urine samples. Based on red tide presence, clinical signs, and postmortem findings, brevetoxicosis caused by presumptive ingestion of toxic dead fish was the likely cause of canid deaths at PAIS. These findings represent the first confirmed report of terrestrial mammalian wildlife mortalities related to a K. brevis bloom. The implications for red tide impacts on terrestrial wildlife populations are a potentially significant but relatively undocumented phenomenon. © Wildlife Disease Association 2013.

IRD (Institut de Recherche pour le Développement), Rue Jean Monnet, BP 171, 34203 Séte, France The inaccessibility of open ocean habitat and the cryptic nature of small animals are fundamental problems when assessing the distribution of oceanic-stage sea turtles and other marine animals sharing similar lifehistory traits. Most methods that estimate patterns of abundance cannot be applied in situations that are extremely data limited. Here, we use a movement ecology framework to generate the first predicted distributions for the oceanic stage of the Kemp's ridley sea turtle (Lepidochelys kempii). Our simulations of particle dispersal within ocean circulation models reveal substantial annual variation in distribution and survival among simulated cohorts. Such techniques can help prioritize areas for conservation, and supply inputs for more realistic demographic models attempting to characterize population trends. © 2013 The Author(s) Published by the Royal Society.

CORPUS CHRISTI, TX--(Marketwired - February 15, 2017) - On Saturday, February 11, the Texas State Aquarium's Second Chances Wildlife Rehabilitation Hospital released eight rehabilitated green sea turtles back into their natural habitat on Padre Island National Seashore in Corpus Christi, Texas. The green sea turtles were brought to the Second Chances hospital on January 9 at the request of the Padre Island National Seashore after becoming cold-stunned during a recent temperature drop in the Corpus Christi area. Cold-stunning is a hypothermic reaction that sea turtles can develop when exposed to cold water for a prolonged amount of time since turtles are cold-blooded and cannot warm themselves. Cold-stunned turtles are unable to swim and can develop symptoms including decreased heart rate and circulation and pneumonia. If they do not receive treatment, cold-stunned sea turtles can die. Second Chances staff was able to warm the sea turtles to raise their body temperature and provided them with additional medical care. On January 16, 16 sea turtles were released into their natural habitat in the Gulf of Mexico. The eight sea turtles released on Saturday remained with Second Chances for more treatment until they were declared ready to be released last week. The release was extremely successful, and all of the turtles swam off immediately after being placed in the water. "This release was another huge moment for the Second Chances team, and we are ecstatic to see this final group of sea turtles returned to the ocean," said Manager of Wildlife Rehabilitation Laura Martinelli. "This is just the start of our program's involvement with sea turtle rehabilitation, and we look forward to working with Padre National Island Seashore and the community to give sea turtles and other animals a second chance at life." Second Chances is asking the public to take watch for cold-stunned turtles on the beach, especially during colder days. If you locate a stranded turtle, do not attempt to touch or handle it, but call 1-866-TURTLE-5 to notify wildlife rescuers who can pick up the turtle and arrange for its treatment.
