Wildlife rehabilitation programs are widely employed for many endangered marine species and can serve as engaging platforms environmental outreach. However, their effectiveness at supporting populations in the wild depends on whether rescued animals survive reproduce after being released. Here, we assessed cold-stunned juvenile sea turtles resumed typical migratory diving behaviors rehabilitation. We deployed satellite transmitters onto 7 rehabilitated loggerhead Caretta caretta , 12 green...

The macro-epibiotic communities of sea turtles have been subject to growing interest in recent years, yet their micro-epibiotic counterparts are almost entirely unknown. Here, we provide the first evidence that diatoms epibionts for all seven extant species turtle. Using Scanning Electron Microscopy, inspected superficial carapace or skin samples from a single representative each turtle species. We distinguished 18 diatom taxa these individuals, with hosting at least two taxa. recommend...

Escherichia coli was isolated from feral house mice (Mus domesticus) during the course of a mouse plague in state Victoria, Australia. The isolates were characterized for production colicins and their resistance to co-occurring colicins. Of 447 examined, 59% found be colicinogenic. Phenotypic PCR-based genotypic methods used determine types being produced. Colicin E2 most common, representing 27% colicin-producing isolates. la produced by 3% colicinogenic remaining could not identified, but...

The diatom genus Proschkinia is a common element of biofilms covering diverse substrata in saline inland or shallow coastal environments. It can be distinguished from other naviculoid taxa by its lanceolate valves with fistula located within the central area and numerous open girdle bands U-shaped cross-section single row perforations on internal side fold. Despite this distinct morphology, frustules are typically weakly silicified often overlooked when cleaned material analysed. current...

Sea turtles host a diverse array of epibionts, yet it is not well understood what factors influence epibiont community composition. To test whether communities sea are influenced by the hosts’ nesting or foraging habitats, we characterized epibiota leatherback, olive ridley and green at single location on Pacific coast Costa Rica. We also compared these to conspecific populations elsewhere in East Pacific. If predicted that sympatrically would have comparable taxa. Alternatively, if...

Balaenophilus umigamecolus are reported for the first time in eastern Pacific, from Jalisco coast of western Mexico. Two new hosts represented: olive ridley turtle, Lepidochelys olivacea, and black Chelonia mydas agassizi. Data indicate a distinct correlation between presence B. copepods Stomatolepas praegustator, barnacles that grow imbedded turtle skin. This relationship may have implications marine health.

Several populations of a new Craspedostauros species were observed on museum specimens juvenile green turtle and Kemp's ridleys collected from Long Island Beach, New York, USA. The taxon, alatus Majewska & Ashworth sp. nov., exhibits distinctive set morphological features typical the genus, including cribrate areolae, stauros narrower than fascia, multiple doubly perforated girdle bands, two fore aft chloroplasts, but clearly differs all known in possessing partially fused proximal...

ABSTRACT The use of animal‐borne devices (= biologgers) has revolutionized the study marine megafauna, yet there remains a paucity data concerning behavioral and physiological impacts biologger attachment retention. Here, we used cameras to characterize behavior dive duration juvenile green turtles ( Chelonia mydas ) in Bahamas for up 210 min after deployment n = 58). For “control,” unoccupied aerial vehicles (UAVs) collect comparable from nonhandled 25) same habitats. Animal‐borne footage...

AbstractThe barnacles Stomatolepas elegans and praegustator are epibionts of sea turtles. The former is described as inhabiting the external skin turtles latter inside mouth gullet. This study evaluated genetic divergence among 69 traditionally defined individual S. six from 18 representing four host species five geographic locations in Atlantic Pacific Oceans. Genetic variation was compared for a 658-base-pair portion mitochondrial cytochrome c oxidase subunit I gene locus. Our findings...

There is a wealth of published information on the epibiont communities sea turtles, yet many these studies have exclusively sampled epibionts found only carapace. Considering that may be almost all body-surfaces and it highly plausible to expect different regions body host distinct taxa, there need for quantitative spatial variation turtles. To achieve this, we measured how total abundance biomass olive ridley turtles Lepidochelys olivacea varies among four body-areas hosts (n = 30). We...

Abstract Six polymorphic microsatellite loci containing dinucleotide repeats were developed for the freshwater turtle Mauremys rivulata . The number of alleles ranged from five to 18. observed and expected heterozygosities 0.19 0.79 0.46 0.90, respectively. These markers may serve as a valuable tool population genetics analyses provide information on evolutionary history species.

First sampled in the late 1990s, Campamento Tortuguero La Gloria, Jalisco, Mexico, was resampled for olive ridley sea turtle (Lepidochyles olivacea Eschscholtz) diversity 10 years later. A comparison with all previously reported mitochondrial sequences revealed that these new samples added to known genetic this species, and unexpectedly high among turtles nesting on beach. The results highlight importance of systematic resampling rookeries verify study populations. Three haplotypes are...

A three-dimensional (3D) approach for visualizing the phyletic relationship of living animals is proposed and developed as an alternative to current two-dimensional (2D) evolutionary trees. The 3D tree enhances visualization qualitative analysis since it simultaneously provides topological (tree-structure) spatial information (based upon genetically measured distances). However, meaning third dimension, particularly its temporal processes, further quantitative analyses emerge open questions....

Abstract In spite of numerous references to Tretanorhinus as a natricine or natricid snake, significant characters the dentition, vertebrae, hemipenis, and scutellation agree with previous immunological data which indicated that is member Central American Dipsadidae. The karyotype variabilis supports view this genus not natrid.

There is very little information of the foraging ecology and parasite infections many snake species. Here, we used opportunistically collected roadkill to assess diet prevalence in two species The Bahamas, Bahamian Racer (Cubophis vudii vudii) Boa (Chilabothrus strigilatus strigilatus). Over eight months, conducted up four daily routine road surveys along a 10 km stretch highway, as well opportunistic elsewhere on island Eleuthera. Overall, 270 roadkilled snakes which less than half (39%)...

Considering that may be almost all body-surfaces and it highly plausible to expect different regions body host distinct taxa, there need for quantitative comparative investigate spatial variation in turtles.
