Few at-sea behavioural data exist for oceanic-stage neonate sea turtles, a life-stage commonly referred to as the turtle ‘lost years’. Historically, long-term tracking of small, fast-growing organisms in open ocean was logistically or technologically impossible. Here, we provide first satellite tracks turtles. Loggerheads ( Caretta caretta ) were remotely tracked Atlantic Ocean using small solar-powered transmitters. We show that turtles (i) rarely travel Continental Shelf waters, (ii)...

Stable isotope analysis is a useful tool to track animal movements in both terrestrial and marine environments. These intrinsic markers are assimilated through the diet may exhibit spatial gradients as result of biogeochemical processes at base food web. In environment, maps predict distribution stable isotopes limited, thus determining geographic origin has been reliant upon integrating satellite telemetry data. Migratory sea turtles regularly move between foraging reproductive areas....
Determining patterns of migratory connectivity for highly-mobile, wide-ranging species, such as sea turtles, is challenging. Here, we combined satellite telemetry and stable isotope analysis to estimate foraging locations 749 individual loggerheads nesting along the east central Florida (USA) coast, largest rookery Northwest Atlantic population. We aggregated results by year, identified seven hotspots tracked these summaries describe dynamics inter-annual contributions geographic areas this...
In-water behaviour and long-term movements of oceanic-stage juvenile sea turtles are not well described or quantified. This is owing to technological logistical limitations tracking small, fast-growing animals across long distances time periods within marine habitats. Here, we present, our knowledge, the first offshore tracks oceanic green (Chelonia mydas) in western North Atlantic waters. Using a tag attachment technique developed specifically for young (less than 1 year old) turtles,...
Several marine turtle species spend their first years of life in oceanic habitats. This early stage is referred to as the ‘lost years’ due difficulty accessing individuals for study offshore. We satellite tracked 114 wild-caught juvenile turtles (straight carapace lengths 12.3–29.9 cm) from Gulf Mexico between 2011 and 2022 investigate movements with respect traditional definitions assigned stage. Satellite-tracked included 79 green ( Chelonia mydas ), 26 Kemp’s ridleys Lepidochelys kempii 5...
In the South Atlantic Ocean, few data exist regarding dispersal of young oceanic sea turtles. We characterized movements laboratory-reared yearling loggerhead turtles from Brazilian rookeries using novel telemetry techniques, testing for differences in during different periods turtle hatching season that correspond to seasonal changes ocean currents. Oceanographic drifters deployed alongside satellite-tagged allowed us explore mechanisms (passive drift or active swimming). Early transited...
The inaccessibility of open ocean habitat and the cryptic nature small animals are fundamental problems when assessing distribution oceanic-stage sea turtles other marine sharing similar life-history traits. Most methods that estimate patterns abundance cannot be applied in situations extremely data limited. Here, we use a movement ecology framework to generate first predicted distributions for oceanic stage Kemp's ridley turtle ( Lepidochelys kempii ). Our simulations particle dispersal...
Oceanic dispersal characterizes the early juvenile life‐stages of numerous marine species conservation concern. This stage may be a ‘critical period’ for many species, playing an overriding role in population dynamics. Often, relatively little information is available on their distribution during this period, limiting effectiveness efforts to understand environmental and anthropogenic impacts these species. Here we present simple model predict annual variation abundance oceanic‐stage sea...

The Archie Carr National Wildlife Refuge (ACNWR), located along the central east coast of Florida (USA) in western North Atlantic, hosts one largest loggerhead (Caretta caretta) nesting assemblages Hemisphere.Sea turtle activity has been continuously monitored on this beach for .31 yrs, representing longest sea reproductive data sets world.Between 1982 and 2012, an estimated 358,243 nests were deposited ACNWR with annual mean plus 95% confidence interval 11,556 ± 1,129 nests.This constitutes...
Predictions of organismal movements in a fluid require knowing the fluid's velocity and potential contributions organism's behaviour (e.g. swimming or flying). While theoretical aspects this work are reasonably well-developed, field-based validation is challenging. A much-needed study recently published by Briscoe colleagues Proceedings Royal Society B compared distribution satellite-tracked juvenile sea turtles to virtual particles released data-assimilating hindcast ocean circulation...
Understanding the drivers of fisheries bycatch is essential for limiting its impacts on vulnerable species. Here we present a model to estimate relative magnitude sea turtle in major coastal across southeastern US based spatiotemporal variation fishing effort and simulated distributions juvenile Kemp's ridley (Lepidochelys kempii) green (Chelonia mydas) turtles recruiting from oceanic nearshore habitats. Over period modeled (1996-2017), recreational was estimated be greater than sum that...
Assessments of large-scale disasters, such as the Deepwater Horizon oil spill, are problematic because while measurements post-disturbance conditions common, pre-disturbance baselines only rarely available. Without adequate observations pre-disaster organismal and environmental conditions, it is impossible to assess impact catastrophes on animal populations ecological communities. Here, we use long-term biological tissue records provide data for a vulnerable marine organism. Keratin samples...
Abstract For species reaching maturity at a range of ages or sizes, factors that influence juvenile growth and size may have lasting impacts on overall fitness. Assessing when animals reach is especially challenging for which are difficult to follow through time as result highly migratory behavior, long life spans, both. We examined nesting female in reproductive assemblage green turtles ( Chelonia mydas ) loggerheads Caretta caretta the east coast Florida, USA. used long‐term dataset from...
Characterizing polymorphism at the major histocompatibility complex (MHC) genes is key to understanding vertebrate immune response disease. Despite being globally afflicted by infectious tumour disease fibropapillomatosis (FP), immunogenetic variation in sea turtles minimally explored. We sequenced α1 peptide-binding region of MHC class I (162 bp) from 268 juvenile green (Chelonia mydas) and 88 loggerhead (Caretta caretta) Florida, USA. recovered extensive (116 alleles) trans-species...
The Kemp's ridley (Lepidochelys kempii) is the most endangered sea turtle species. During 1966–2017, an annual count of nests (i.e., clutches eggs laid) has served as index nesting female abundance on Gulf Mexico (GoM) beach in Tamaulipas, Mexico. This was increasing exponentially at 19% per year 2009, but it dropped unexpectedly by more than a third 2010 and through 2017 remained well below levels predicted. We hypothesize that pre-2010 declining carrying capacity for population within GoM...
