The case of Kanzul beach, Riviera Maya-Tulum (Mexico) 2017 Access copy available to the general public Unrestricted Marine coast modification and human pressure affects many species, including sea turtles. In order to study nine anthropogenic impacts that might affect nesting selection of females, incubation and hatching survival of loggerhead (Caretta caretta) and green turtle (Chelonia mydas), building structures were identified along a 5.2 km beach in Kanzul (Mexico). A high number of hotels and houses (88; 818 rooms), with an average density of 16.6 buildings per kilometer were found. These buildings form a barrier which prevents reaching the beach from inland, resulting in habitat fragmentation. Main pressures were detected during nesting selection (14.19% of turtle nesting attempts interrupted), and low impact were found during incubation (0.77%) and hatching (4.7%). There were three impacts defined as high: beach furniture that blocks out the movement of hatchlings or females, direct pressure by tourists, and artificial beachfront lighting that can potentially mislead hatchlings or females. High impacted areas showed lowest values in nesting selection and hatching success. Based on our results, we suggest management strategies to need to be implemented to reduce human pressure and to avoid nesting habitat loss of loggerhead and green turtle in Kanzul, Mexico. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.16 2017 MARINE & FRESHWATER BIOLOGY 64 / 106 = 0.604 2017 Q3 T2 ENVIRONMENTAL SCIENCES 186 / 241 = 0.772 2017 Q4 T3 0.393 2017 Ecology 2017 Q3 Oceanography 2017 Q3 Nature and Landscape Conservation 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Arenas Martínez, Alejandro Tzeek Tuz, Miriam (orcid)0000-0002-8731-1009 Pérez-Collazos, Ernesto Universidad de Zaragoza 5011 063 Universidad de Zaragoza Dpto.
