The waters around Bimini (25° 43.70′ N, 79° 18.00′ W) provide an ideal nursery location for juvenile lemon sharks, Negaprion brevirostris, but this habitat is threatened by the development of a large resort. [...] Key Method Possible effects from the development up to June 2006 were investigated by: comparing growth rates of juvenile lemon sharks in the NS, Sharkland (SL) and South Bimini (SB) nurseries between 1995-2005 using before-after, control-impact (BACI) analysis; analyzing survival of juvenile lemon…Expand

Epigenetic responses in juvenile Lemon sharks (Negaprion brevirostris) during a coastal dredging episode in Bimini, Bahamas
TLDR
Overall, the findings of this study support DNA methylation as a potential stress biomarker for sharks, even in the absence of a reference genome. Expand
Age and growth of juvenile lemon sharks (Negaprion brevirostris) at an insular nursery in the southern Caribbean
TLDR
Growth rate increased with age during the first 4 years of life for lemon sharks at Los Roques, while they occupied the nursery area, and comparison of growth rates among geographically separate nursery areas showed no obvious relationships between growth rate and latitude or temperature. Expand
Nursery area and size structure of the lemon shark population, Negaprion brevirostris (Poey, 1868), in Los Roques Archipelago National Park, Venezuela
TLDR
Overall data showed that the area occupied by juvenile lemon sharks was clearly partitioned into primary and secondary nurseries, and nighttime activity seemed to change according to the size of sharks in the primary nursery, suggesting a reduction of time activity overlapping among juveniles of distinct size/age.

Abstract Estimates of the survival of juvenile sharks within their critical habitats are important in defining the dynamic of the species and designing management strategies. The objective of thisExpand
Three decades of longlining in Bimini, Bahamas, reveals long-term trends in lemon shark Negaprion brevirostris (Carcharhinidae) catch per unit effort.
TLDR
The temporal pattern of CPUE indicated an abundance trend with a complete cycle, from trough to trough, occurring over a period of approximately 18 years, and the long-term trend identified in this study provides a baseline for future assessment. Expand
The spatiotemporal dynamics of habitat use by blacktip (Carcharhinus limbatus) and lemon (Negaprion brevirostris) sharks in nurseries of St. John, United States Virgin Islands
TLDR
The results of this study indicate that Fish Bay and Coral Bay are nursery areas that warrant designation as essential fish habitat and exemplify the need for additional focused management measures. Expand
Local indicators of abundance and demographics for the coastal shark assemblage of Bimini, Bahamas
TLDR
Results from this study improve the understanding of the coastal shark assemblage in Bimini, Bahamas, and provide important local abundance trend information that could be beneficial for conservation and regional assessments. Expand
Assessing the incidental value of a marine reserve to a lemon shark Negaprion brevirostris nursery
TLDR
The area occupied by the Bell Sound Nature Reserve appears to be highly important to the local juvenile lemon shark population, with the predominantly shallower near shore waters of the Reserve offering a greater level of protection from predation. Expand
Discovery of a multispecies shark aggregation and parturition area in the Ba Estuary, Fiji Islands
TLDR
A fisheries‐independent shark survey from the Fiji Islands helps enhance the understanding of shark ecology in Fiji and provide a scientific basis for the implementation of local conservation strategies that contribute to the protection of these threatened species. Expand
Utility of a multi-faceted approach in determining the habitat use of endangered euryhaline elasmobranchs in a remote region of northern Australia
The overriding aim of this thesis was to explore the habitat use of the critically endangered freshwater sawfish (Pristis microdon) and northern river shark (Glyphis garricki) in the remote KimberleyExpand

Survival of Juvenile Lemon Sharks at Bimini, Bahamas, Estimated by Mark–Depletion Experiments
TLDR
Estimates of survival rates in the present study were negatively correlated with estimated initial abundance and are consistent with strong, density-dependent survival. Expand
Spatial and ontogenetic variation in growth of nursery-bound juvenile lemon sharks, Negaprion brevirostris: a comparison of two age-assigning techniques
TLDR
Two methods of age analysis were applied and tested: a modified ‘minimum convex polygon’ method and a new age-assigning method, the ‘cut-off technique’, which proved to be the more suitable one, enabling the age of 134 of the 642 previously unknown aged sharks. Expand

TLDR
The present data suggest that the impact studied may be considered as a pulse disturbance, since leaf production appeared to recover over a comparatively short-time scale if compared to the low turn-over and high longevity of P. oceanica. Expand
Latitudinal variation in life-history traits of bonnethead sharks, Sphyrna tiburo, (Carcharhiniformes : Sphyrnidae) from the eastern Gulf of Mexico
TLDR
Male and female bonnetheads in north-west Florida had the fastest growth rate compared with the other locations, supporting the hypothesis that growth rate is inversely related to the length of the growing season and supporting evidence that a pattern of latitudinal variation exists. Expand
The breeding biology of lemon sharks at a tropical nursery lagoon
TLDR
The ubiquitous polyandry reported here raises the possibility that genetic incompatibility and post–copulatory paternity–biasing mechanisms may operate in viviparous sharks. Expand
Growth rates of juvenile dusky sharks, Carcharhinus obscurus (Lesueur, 1818), from southwestern Australia estimated from tag-recapture data
Tag-recapture data are a useful source of information on the growth of animals. The simplest form of analysis is to estimate an average growth rate, normally for a specifi c size range, from theExpand
Growth and maturity of salmon sharks (Lamna ditropis) in the eastern and western North Pacific, and comments on back-calculation methods
TLDR
The results show that female and male salmon sharks in the eastern North Pacific possess a faster growth rate, reach sexual maturity earlier, and attain greater weight-at-length than their same-sex counterparts living in the western North Pacific. Expand
Habitat selection by juvenile lemon sharks,Negaprion brevirostris
SynopsisWe surgically implanted ultrasonic transmitters in 38 lemon sharks,Negaprion brevirostris, and manually tracked the sharks for 1–153 days. This yielded 2281 positional fixes recorded atExpand
Are growth and density quantitative indicators of essential fish habitat quality? An application to the common sole Solea solea nursery grounds
TLDR
The combination of these variables appears to provide reliable indicators of habitat quality and anthropogenic pressure on nursery grounds, especially highlighting contaminated areas, and may contribute to improve assessment of environmental quality of essential fish habitats with the aim of a sustainable management of fisheries resources.

Influence of teleost abundance on the distribution and abundance of sharks in Florida Bay, USA
TLDR
Although there does not appear to be a strong match between the abundance of teleosts and sharks at small spatial scales, regional shark abundance is likely driven, at least partially, by the availability of prey. Expand
