Ghost Crab (Ocypode Quadrata) Abundance and Depredation on Loggerhead
Ghost crab (Ocypode quadrata) abundance and depredation on Loggerhead sea turtle (Caretta caretta) hatchlings on Onslow Beach, North Carolina Sara R. Marschhauser 2010 Advisor: Dr. Christopher DePerno College of Natural Resources, North Carolina State University Advisory Committee: Dr. Stephen Fegley (Institute of Marine Sciences, University of North Carolina) and Dr. Ted Simons (College of Agriculture and Life Sciences, North Carolina State University) Introduction Sea turtles must overcome nest mortality and avoidance of predators following emergence from the nest (Fowler 1979, Miller 2003). Nest mortality can occur due to nest placement, erosion, development of beaches, temperature, and predators (Lutz & Musick 1997, McFarlane 1963). In some locations predators, (e.g., raccoons, foxes and crabs) are the main cause of nest mortality (Barton & Roth 2008, Engeman et al. 2003, Fowler 1979, Garmenstani 2005, Ratnaswany & Warren 1998) and may be the main cause of sea turtle hatchling mortality. Management of sea turtle nests has decreased the mortality of sea turtle nests and hatchlings by some predators in North Carolina (Cordes & Rikard 2005); however, the effect of the current predator management policy of removing raccoons is unknown, but this practice may be causing an increase in other predator populations, such as ghost crabs (Ocypode quadrata). Little is known regarding the depredation rates of sea turtle hatchlings by ghost crabs; however, the abundance and distribution of ghost crabs along Onslow Beach varies dramatically between different areas of the beach (S. Fegley, pers. comm.), which may make sea turtle hatchlings at certain areas of the beach more susceptible to predation. Also, beach characteristics may be responsible for increased depredation. -
Who Are the Important Predators of Sea Turtle Nests at Wreck Rock Beach?
Who are the important predators of sea turtle nests at Wreck Rock beach? Juan Lei and David T. Booth School of Biological Sciences, The University of Queensland, Brisbane, St. Lucia, Australia ABSTRACT Excessive sea turtle nest predation is a problem for conservation management of sea turtle populations. This study assessed predation on nests of the endangered loggerhead sea turtle (Caretta caretta) at Wreck Rock beach adjacent to Deepwater National Park in Southeast Queensland, Australia after a control program for feral foxes was instigated. The presence of predators on the nesting dune was evaluated by tracking plots (2 × 1 m) every 100 m along the dune front. There were 21 (2014–2015) and 41 (2015–2016) plots established along the dune, and these were monitored for predator tracks daily over three consecutive months in both nesting seasons. Predator activities at nests were also recorded by the presence of tracks on top of nests until hatchlings emerged. In addition, camera traps were set to record the predator activity around selected nests. The tracks of the fox (Vulpes vulpes) and goanna (Varanus spp) were found on tracking plots. Tracking plots, nest tracks and camera traps indicated goanna abundance varied strongly between years. Goannas were widely distributed along the beach and had a Passive Activity Index (PAI) (0.31 in 2014–2015 and 0.16 in 2015–2016) approximately seven times higher than that of foxes (PAI 0.04 in 2014–2015 and 0.02 in 2015–2016). Five hundred and twenty goanna nest visitation events were recorded by tracks but no fox tracks were found at turtle nests. -

Casciaro, 73100 Lecce, Italy * corresponding author: [email protected] OCCURRENCE OF OCYPODE CURSOR (LINNAEUS, 1758) (CRUSTACEA, DECAPODA) IN SALENTO (SOUTHERN ITALY) SUMMARY Ocypode cursor (Linnaeus, 1758) is the only Ocypode species present in the Mediterranean Sea. It is widely distributed in the southern part of the basin (mainly African coast) and only recently it has been reported also from Sicil- ian Ionian sea. The present record is the first for Italian peninsula and the northernmost record of O. cursor in the Mediterranen Sea. INTRODUCTION The tufted ghost crab Ocypode cursor (Linnaeus, 1758) is a semi-terrestrial burrowing brachyuran of nocturnal habits generally found in supratidal and intertidal sandy beaches (STRACHAN et al., 1999). The species is the only member of the family Ocypodidae occurring in the Mediterranean Sea; specifically, it is characterized by a disjoint distribu- tion, comprising the eastern Mediterranean Sea and tropical coasts of the eastern Atlantic Ocean as far south as northern Namibia, with the exclusion of the western Mediterranean. -

17 the Crabs Belonging to the Grapsoidea Include a Lot Of
17 SUPERFAMILY GRAPSOIDEA The crabs belonging to the Grapsoidea include a lot of ubiquitous species collected in the mangrove and/or along the coastline. As a result, most of the species listed here under the ‘Coastal Rock-rubble’ biotope of table 2b could be reasonably listed also with marine species. This is particularly true for the Grapsidae: Grapsus, Pachygrapsus, Pseudograpsus, and Thalassograpsus. FAMILY GECARCINIDAE Cardisoma carnifex (Herbst, 1796).

These crabs have been used as ecological 17 indicators of the levels of anthropogenic impacts on sandy beaches. Our aim is to report the 18 variety of burrow architecture types constructed by ghost crabs Ocypode quadrata on 19 beaches of Maceió, Brazil. We found 20 types of burrows that differ in shape (number of 20 axes, number of openings, orientation of blind end, number of branches). The slash-shaped 21 burrows (type C) were the most frequent shape, followed by types K (spiral) and E (Y- 22 shaped). -

Such data are necessary for implementing more efficient monitoring programs that quantify the dynamics of key ecological attributes on sandy beaches. This article contributes to the bioecology of ghost crabs from subtropical Praia Brava, Itajaı´, Santa Catarina. Ocypode quadrata occurs in sandy beaches along the tropical–temperate western Atlantic, from Rhode Island (US) to Rio Grande do Sul (Brazil). During 14 consecutive months, a total of 649 specimens were captured: 255 females (39%), 241 males (37%), and 153 juveniles of undetermined sex (24%). Highest densities were recorded in June and November, with a total of 1,900 burrows distributed along the beach (56.95%) and dunes (43.05%). Sixteen natural diet items were identified for this crab, with a larger participation of Apis spp. (38.97% of relative volume). In the local food web, the ground-burrowing owl Speotyto cunicularia was the main crab predator.
