The large-scale spatial dynamics and population structure of marine top predators are poorly known. We present electronic tag and photographic identification data showing a complex suite of behavioral patterns in white sharks. These include coastal return migrations and the fastest known transoceanic return migration among swimming fauna, which provide direct evidence of a link between widely s...

There were 479 reported whale shark Rhincodon typus encounters between 1999 and 2011 at the island of Utila, which forms part of the Meso-American Barrier Reef System (MBRS) in the western Caribbean Sea. The majority of R. typus were found to feed on small bait fish associated with various tuna species. Ninety-five individual R. typus, ranging from 2 to 11 m total length (LT ), were identified ...

This workshop will present the importance of creative work in the clinical practice of the clinician or bioethicist. First I will present some of the narratological theories of close reading and aesthetic theories of creative writing. We will join in close reading of one or two clinical texts and literary texts, creative writing in the context of those texts, and then reading to one another wha...

chronic myeloid leukemia (cml) is a myeloproliferative disease. the cytogenetic hallmark of cml is philadelphia (ph) chromosome. this study aimed to diagnose suspected cml patients, to monitor cml patients under therapy using cytogenetic and fluorescence in situ hybridization (fish) techniques to analyze their bone marrow (bm) and peripheral blood (pb) samples, and finally to compare their obta...

Many shark populations are in danger of extinction as a direct result of man's activities. A change in attitude and a greater understanding of species' requirements are needed to prevent further destruction and replenish numbers, thus sustaining trade, fisheries and sport activity.

Laser photogrammetry was found to be a promising new cost-effective technique for measuring free-swimming whale sharks Rhincodon typus. Photogrammetric measurements were more precise than visual size estimates by experienced researchers, with results from the two methods differing by 9· 8 ± 1· 1% (mean ±s.e.). A new metric of total length and the length between the fifth gill and first dorsal f...

1. Animal search patterns reflect sensory perception ranges combined with memory and knowledge of the surrounding environment. 2. Random walks are used when the locations of resources are unknown, whereas directed walks should be optimal when the location of favourable habitats is known. However, directed walks have been quantified for very few species. 3. We re-analysed tracking data from thre...
