A recent study by Clua et al. (2010; Mar Ecol Prog Ser 414:257–266) that looks at the behavioural response of sicklefin lemon sharks Negaprion acutidens to underwater feeding for ecotourism purposes has a number of methodological and semantic problems that complicate the evaluation of the results and raise questions about the conclusions. Main issues are the lack of a control, the use of non-de...

Abstract The Punjab urial (Ovis vignei punjabiensis) is a globally threatened wild sheep species. In Pakistan the species legally protected and bred in captivity to release into natural habitats reinforce populations. Vigilance feeding are critical survival, though degree which captive-bred animals exhibit these behaviours post-release has rarely been investigated. We monitored daily of five ad...

Food ingestion is one of the defining behaviours of all animals, but its quantification and analysis remain challenging. This is especially the case for feeding behaviour in small, genetically tractable animals such as Drosophila melanogaster. Here, we present a method based on capacitive measurements, which allows the detailed, automated and high-throughput quantification of feeding behaviour....

Selective Serotonin Re-uptake Inhibitors (SSRI) are mood-altering, psychotropic drugs commonly used in the treatment of depression and other psychological illnesses. Many of them are poorly degraded in sewage treatment plants and enter the environment unaltered. In laboratory studies, they have been demonstrated to affect a wide range of behaviours in aquatic organisms. In this study we investi...

Neuropeptides have central roles in the regulation of homoeostatic behaviours such as sleep and feeding. Caenorhabditis elegans displays sleep-like quiescence of locomotion and feeding during a larval transition stage called lethargus and feeds during active larval and adult stages. Here we show that the neuropeptide NLP-22 is a regulator of Caenorhabditis elegans sleep-like quiescence observed...

The effect of different stages of the tidal cycle, weather conditions and the presence of conand allo-specifics on the time and activity budgets of Eurasian Oystercatchers Haematopus ostralegus was investigated. Data were collected at a breeding site on Lundy Island in the Bristol Channel, UK, where Oystercatchers feed on limpets Patella spp. on rocky shores. Sixteen behaviours were recorded fo...

Aim of study: To describe the common behaviour flathead grey mullet (Mugil cephalus) under rearing conditions.
 Area Tepic, Mexico.
 Material and methods: Behaviours exhibited by mullets were videorecorded with submersible cameras installed inside three tanks. A total 690 min per day (07:30 - 18:30 h) recorded tank during a week. Afterwards, different behaviours juvenile M. cephalus d...

OBJECTIVES To study the relationship between exercise by the mother and breast-feeding initiation and duration, and its effect on infant growth. DESIGN A cohort study of mothers and infants, recruited at birth. Infant feeding methods were recorded in detail and breast-feeding was categorised as 'any' or 'full'. Exercise levels were categorised using the metabolic equivalent tasks approach bas...

Global evidence shows that children's growth deteriorates rapidly during/after illness if foods and feeding practices do not meet the additional nutrient requirements associated with illness/convalescence. To inform policies and programmes, we conducted a review of the literature published from 1990 to 2014 to document how children 0-23 months old are fed during/after common childhood illnesses...

the aim of the current investigation was to evaluate the sedentary lifestyle of the polish population and its link with prolonged sitting in light of individual and environmental factors.the sample consisted of 1505 polish people between 18 and 64 years old. the computer-assisted telephone interview (cati) survey was conducted with the polish version of international physical activity questionn...
