Abstract Along the coasts of Florida, beach erosion caused by large storms and hurricanes coincides with the nesting season of the Loggerhead Sea Turtle. Here, we report the effects of beach renourishment and nest relocation on the success of Loggerhead Sea Turtle (Caretta caretta) eggs and hatchlings. Data on ∼53,700 Loggerhead Sea Turtle eggs from 517 clutches were collected over a six-year period, 2006 through 2011, on the Gulf Coast beaches of Pinellas County, Florida. We compared the… 

Impact of nest relocation on the reproductive success of Loggerhead Turtles, Caretta caretta, in the Göksu Delta, Turkey (Reptilia: Cheloniidae)

TLDR
The effect of nest relocation on Loggerhead Turtle (Caretta caretta) egg hatching success during the 2013 and 2014 nesting seasons in the Göksu Delta, Mersin, Turkey was determined.

Potential for Relocation to Alter the Incubation Environment and Productivity of Sea Turtle Nests in the Northern Gulf of Mexico

TLDR
Given that relocation did not improve nest productivity nor reduce the likelihood of inundation, this practice conferred minimal net benefit to sea turtle nests on dissipative-to-intermediate beach conditions typical of the northern Gulf of Mexico.

Mid‐incubation relocation and embryonic survival in loggerhead sea turtle eggs

TLDR
Although moving nests later than 12 hours decreases nest success and should be a matter of last resort, the forecasts for increased storm activity and sea level rise, and other impacts such as beach oiling, may necessitate nest relocation under less than ideal circumstances.

A literature review of beach nourishment impacts on marine turtles

This Technical Report was developed by the U. S. Army Engineer Research and Development Center-Environmental Laboratory (ERDC-EL), to summarize the known impacts to nesting sea turtles along the

Multiple maternal risk-management adaptations in the loggerhead sea turtle (Caretta caretta) mitigate clutch failure caused by catastrophic storms and predators

TLDR
It is concluded that diversified maternal investments over time and space by nesting females are reproductive adaptations that have successfully offset clutch losses, thus enabling populations of loggerhead females to meet or exceed their reproductive goal of replacement fitness.

Are we working towards global research priorities for management and conservation of sea turtles

In 2010, an international group of 35 sea turtle researchers refined an initial list of more than 200 research questions into 20 metaquestions that were considered key for management and conservation

Beach Renourishment and Loggerhead Turtle Reproduction: A Seven Year Study At Jupiter Island, Florida

The effects of beach renourishment on a major marine turtle nesting beach (Jupiter Island) in Florida were studied over seven years. This made possible a long-term comparison between reproductive

Estimating the Effect of Beach Nourishment on Caretta caretta (Loggerhead Sea Turtle) Nesting

Caretta caretta (loggerhead sea turtle) nesting activity was recorded daily during three seasons prior to and two seasons immediately following a beach nourishment (replenishment) project in Palm

Effects of Nest Relocation on Nest Temperature and Embryonic Development of Loggerhead Sea Turtles (Caretta caretta)

TLDR
It is shown that nest relocation can be used to alleviate nests of extreme abiotic conditions to increase hatch success, without altering embryonic development.

EFFECTS OF FIRE ANTS (HYMENOPTERA: FORMICIDAE) ON HATCHING TURTLES AND PREVALENCE OF FIRE ANTS ON SEA TURTLE NESTING BEACHES IN FLORIDA

TLDR
Red imported fire ants (Solenopsis invicta Buren) have increasingly been observed in loggerhead and green sea turtle nests in Florida, and in the nests of freshwater turtles, increasing the vulnerability of hatchlings to fire ant predation.

Nest‐Site Selection in Individual Loggerhead Turtles and Consequences for Doomed‐Egg Relocation

TLDR
The results suggest that doomed-egg relocation does not substantially distort the gene pool in the eastern Australian loggerhead stock and should not be abandoned as a strategy for the conservation of marine turtle populations.

Decreasing annual nest counts in a globally important loggerhead sea turtle population.

TLDR
It is argued that the decline in annual loggerhead nest counts in peninsular Florida can best be explained by a decline in the number of adult female loggerheads in the population.

Egg Failure in Natural and Relocated Sea Turtle Nests

TLDR
Eggs of the loggerhead sea turtle, Caretta caretta, often fail to hatch were investigated as sources of egg failure, showing that standard methods of estimating infertility of eggs produce overestimates and egg relocation is an effective conservation method, provided sites are chosen carefully.

Nest placement by loggerhead turtles, Caretta caretta

TLDR
Nest placement by loggerhead turtles nesting on the island of Cephalonia, Greece, was examined and found that most nests were laid in positions where hatchling success was high, and sand temperatures at the depths where eggs incubated were higher further from the sea.
