“…Thus, the value of the Tortugas NTMR network as a habitat and foraging ground for sedentary and highly mobile species may increase through time (Bartholomew et al 2008). Our observations suggest that these NTMRs may promote surrounding fisheries, in the near-term through spillover into fishable areas, and in the long-term through increased spawning stock biomass.…”

Home ranges, activity patterns, and habitat preferences in and around no-take marine reserves (NTMRs) were evaluated for 5 exploited snapper-grouper species in diverse coral reef habitats in the Dry Tortugas, Florida. Movements of ultrasonic tagged reef fish were determined using a calibrated array of omnidirectional hydroacoustic receivers. Average home range sizes were 2.09 ± 0.39 km 2 (n = 28; total length, TL = 45 to 66 cm) for red grouper Epinephelus morio, 4.17 ± 1.75 km 2 (n = 5, TL = 48 to 55 cm) for yellowtail snapper Ocyurus chrysurus, 1.44 ± 1.04 km 2 (n = 2, TL = 57 to 75 cm) for black grouper Mycteroperca bonaci, and 7.64 km 2 (n = 1, TL = 70 cm) for mutton snapper Lutjanus analis. Red grouper and yellowtail snapper moved moderate distances (from 700 to 900 m) with moderate frequency. Observed movements for black groupers were relatively small and infrequent. Mutton snappers appeared to make short, frequent movements. A tracked gray snapper L. griseus made long-distance nocturnal migrations. Several exploited-phase groupers and snappers crossed into and out of reserve boundaries. They were most likely to do so in locations where boundaries were positioned over contiguous coral reef and close to home-range centers. We found that home ranges for red grouper, black grouper, and yellowtail snapper were relatively small in comparison to NTMR area. Our observations suggest that the Dry Tortugas NTMRs may reduce exposure to exploitation for these and other species with limited home ranges, especially where NTMR boundaries do not overlie contiguous reef.

Evidence has already emerged that they are reaching their intended goals (Ault et al. 2006b).Many marine fishes repeatedly use and move throughout particular areas, or home ranges (Burt 1943), for certain periods of the year or for particular life stages (Goeden 1978, Shapiro et al. 1994, Rooij et al. 1996, Zeller 1997, Kramer & Chapman 1999, Bell & Kramer 2000, Bolden 2001, Eristhee & Oxenford 2001, Baras et al. 2002, Lembo et al. 2002, Parsons et al. 2003. Occupation by marine fishes of a particular home range within a spatially heterogeneous landscape -given increased familiarity with key habitat features -may facilitate evasion of predators and increase foraging efficiency (review in Harris et al. 1990).Quantifying short-and longer-term fish movement patterns, home ranges, and habitat use is critical for advancing understanding of the dynamics of reef-fish community ecology and for informing intelligent NTMR design (Russ & Alcala 1996, Palumbi 2001, Meester et al. 2004, O'Dor et al. 2004. Unfortunately, data of this type are extremely limited (Kramer & Chapman 1999, Meyer et al. 2007. As a result, most reserves have been implemented with little quantitative desig...

“…their home range), but also to allow dispersal and cross-boundary movements of early life stages to fishing grounds (i.e. spillover: Kramer & Chapman 1999, Bartholomew et al 2008). In addition, site fidelity is also related to the use of fish as bioindicators, as sedentary species are more suitable for representing local exposure to human impacts (Burger & Gochfeld 2001).…”

We examined the short-term movements of a small temperate fish, the painted comber Serranus scriba (Linnaeus 1758), within the marine protected area (MPA) of Palma Bay (NW Mediterranean) using passive acoustic telemetry. Fifteen adults were surgically implanted with acoustic transmitters and monitored between July 2007 and February 2008 for periods of up to 36 d. Interindividual variability was detected for both spatial and temporal patterns. There were 2 principal movement behaviours that were recorded, with some individuals showing high site fidelity and others showing a more mobile behaviour, moving out from the monitoring area. Observation-area curves indicated that a period between 3 and 5 d was required to determine home ranges of the sedentary fish. Home range sizes were small, with a minimum shift of core areas occurring on a daily basis. Total minimum convex polygon (MCP) areas ranged between 0.102 and 0.671 km 2 , whereas 95% kernel utilization distributions (KUD) ranged between 0.760 and 1.333 km . There were no significant differences in home range patterns between day and night periods. However, the use of the continuous wavelet transform (CWT) revealed diel rhythms on the detection pattern that could be related to a resting behaviour at night. Estimation of home ranges of S. scriba agrees with the sedentary habits of the Serranidae family and suggests the potential use of MPAs for the sustainable development of the fishery of this small Serranid.

“…A holistic approach that includes an adequate management of terrestrial and marine ecosystems and local community involvement is crucial to preserve this natural heritage (Cinner & Pollnac 2004, McClanahan et al 2006, Camargo et al 2009, Ramírez-Herrera et al 2010. Around the world, many valuable studies report the effect of direct activities on coral reefs such as fishing and recreational diving (Coblentz 1997, Hawkins et al 1999, Jameson et al 1999, Tratalos & Austin 2001, Zakai & Chadwick-Furman 2002, Hawkins & Roberts 2004, Bartholomew et al 2008. However, coral reefs in many developing countries are close to coastal villages and cities, and remain exposed to human impact resulting from urban development and the use of inland natural resources with no adequate management strategies.…”

Marine and terrestrial ecosystems are declining globally due to environmental degradation and poorly planned resource use. Traditionally, local government agencies have been responsible of the management of natural reserves to preserve biodiversity. Nonetheless, much of these approaches have failed, suggesting the development of more integrative strategies. In order to discuss the importance of a holistic approach in conservation initiatives, coastal and underwater landscape value and biological/environmental indicators of coral reef degradation were assessed using the study case of Zihuatanejo, Guerrero coastal area. This area shelters representative coral reef structures of the Eastern Pacific coast and its terrestrial biodiversity and archaeology enhance the high value of its coastal area. This study explored the landscape value of both terrestrial and marine ecosystems using the geomorphosite approach in two sites on the Zihuatanejo coastal area: Caleta de Chon and Manzanillo Beach. Sedimentation rate, water transparency, chlorophyll and total suspended solids were recorded underwater in each site for environmental characterization. 50 photo-quadrants on five transects were surveyed between 3-4m depth to record coverage (%) of living corals, dead corals, algae, sand and rocks. The conservation status of coral reefs was assessed by the coral mortality index (MI). Landscape values showed that both terrestrial and marine ecosystems had important scientific and aesthetic values, being Manzanillo Beach the site with the highest potential for conservation initiatives (Ttv=14.2). However, coral reefs face elevated sedimentation rates (up to 1.16kg/m 2 d) and low water transparency (less of 5m) generated by coastal land use changes that have increased soil erosion in the adjacent coastal area. High coverage of dead corals (23.6%) and algae (up to 29%) confirm the low values in conservation status of coral reefs (MI=0.5), reflecting a poorly-planned management. Current conditions are the result of "top-down" conservation strategies in Zihuatanejo, as Federal and Municipal authorities do not coordinate, disregard local community in coral reef management, and ignore the intimate relationship between the coastal and marine realms. This work confirms the importance of conservation strategies with a holistic approach, considering both terrestrial and marine ecosystems in coastal areas; and that these initiatives should include local coastal communities in management and decision-taking processes done by government authorities.
