While fidelity to breeding sites is well demonstrated in marine turtles, emerging knowledge of migratory routes and key foraging limited conservation value unless levels can be established. We tracked green ( Chelonia mydas , n =10) loggerhead Caretta caretta turtles during their post-nesting migration from the island Cyprus grounds. After intervals 2–5 years, five these females were recaptured at nesting beach for a second migration. All used highly similar return same over-wintering areas....

Objectives To investigate the views and experiences of patients regarding their glaucoma follow-up, particularly towards type frequency visual field (VF) testing. Design A qualitative investigation using focus groups. The group discussion used broad open questions around topics in a prompt guide relating to particular, VF monitoring. All groups were taped, transcribed coded manual computer-aided methods. Setting Three National Health Service (NHS) hospitals England; two took place at each...

Most species of marine turtle breed every two or more years and it is the norm for females to lay than one clutch eggs within a nesting season. Knowing interval between breeding seasons frequency (number clutches laid by an individual in season) allows us assess status population. At Alagadi Beach, Northern Cyprus, over period 6 (1995–2000), we attributed 96% green Chelonia mydas 80% loggerhead Caretta caretta known females. This intensive level monitoring enabled estimate both species....

Abstract Sea turtles show temperature dependent sex determination. Using an empirical relationship between sand and air temperature, we reconstructed the nest temperatures since 1855 at Ascension Island, a major green turtle ( Chelonia mydas ) rookery. Our results that inter‐beach thermal variations, previously ascribed to albedo of sand, which varies hugely from one beach another, have persisted for last century. Reconstructed varied by only 0.5 °C on individual beaches over course nesting...

There is a relative paucity of data regarding the at‐sea distribution and behaviour marine turtles. This especially true for critically endangered green turtle Chelonia mydas population in Mediterranean. Six adult female turtles were equipped with satellite transmitters tracked periods between 28 293 d following their final nesting season northern Cyprus. Data elucidated hitherto unknown migratory pathways highlighted importance North African coastal waters as feeding habitat adults this...

ABSTRACT Aim To examine the exploitation, recovery and current status of green turtles ( Chelonia mydas ) nesting at Ascension Island. Location Island (UK) (7°57′ S, 14°22′ W), South Atlantic Ocean. Methods We analysed records harvest between 1822 1935, illustrating decline in numbers over this period. Using a deterministic age‐class structured model we predict initial number breeding females present population prior to recorded compare our estimate based upon recent annual surveys...

Purpose.: To compare face recognition performance of glaucomatous patients with age-similar visually healthy people. Methods.: Percentage correctly identified faces in the Cambridge Face Memory Test was assessed (n = 54; mean age 69) a range visual field (VF) defects and controls 41; 67). All participants underwent cognitive assessment (binocular acuity [BVA], contrast sensitivity [CS], Humphrey VFs, both 10-2 24-2) had BVA at least 0.18 logMAR.

Some studies have shown that the incidence of type 2 diabetes increases after a diagnosis COVID-19, although evidence is not conclusive. However, effects COVID-19 vaccine on this association, or effect other subtypes, are clear. We aimed to investigate association between and 2, 1, gestational non-specific diabetes, COVID- 19 vaccination, up 52 weeks diagnosis.

Abstract Population monitoring is an essential part of evaluating the effectiveness management interventions for conservation. Coastal breeding aggregations marine vertebrate species that come ashore to pup or nest provide opportunistic window observation into otherwise widely dispersed populations.

Sight loss from glaucoma can have a significant impact on functioning and performing everyday activities, but this varies between patients. The purpose of study was to explore whether patients with use different coping strategies in response their vision loss. Audio-recorded semi-structured interviews were conducted 16 (median age: 71 [interquartile range [IQR]: 68 77 years]; 50 % female) about experiences living glaucoma.
