Résumé :

Bycatch mortality is a major factor contributing to shark population declines. Post-release mortality (PRM) is particularly difficult to quantify, limiting the accuracy of stock assessments. We paired blood-stress physiology with animal-borne accelerometers to quantify PRM rates of sharks caught in a commercial bottom longline fishery. Blood was sampled from the same individuals that were tagged, providing direct correlation between stress physiology and animal fate for sandbar (Carcharhinus plumbeus, N = 130), blacktip (C. limbatus, N = 105), tiger (Galeocerdo cuvier, N = 52), spinner (C. bre

Résumé :

Sharks are an interesting group of vertebrates, as many species swim continuously to “ram” oxygen-rich seawater over their gills (ram ventilators), whereas other species “pump” seawater over their gills by manipulating buccal cavity volume while remaining motionless (buccal pumpers). This difference in respiratory physiology raises the question: What are the implications of these differences in lifestyle for circadian rhythms? We investigated the diel activity patterns of 5 species of sharks, including 3 ram ventilating species: the school shark ( Galeorhinus galeus), the spotted estuary smoot

Résumé :

Large marine predators often aggregate seasonally in discrete locations to take advantage of optimal foraging conditions, leading to spatial and temporal variation in their exposure on other species. However, our understanding of the impacts this exposure may have on the behavior and physiology of prey is poor, especially in marine systems. Here, we evaluated the non-consumptive effects of potential exposure to large sharks (white sharks, Carcharodon carcharias (Linnaeus, 1758)) on the stress physiology of an economically important teleost, the striped bass (Morone saxatilis (Walbaum, 1792)),

Résumé :

There is an increasing interest in touristic observations of top predators in the wild. Sharks are probably the most sought-after animal in marine ecosystems by divers. Regulations have been put in place, and even if they are more or less respected, providing food is still used in some places in order to attract wild animals. Because of the difficulty in sampling shark guts, few studies have analyzed the microbiota of sharks, and none have evaluated the effect of feeding on this microbiota. In this work, we compare microbiota assemblages of black-tip sharks between sites with and without regul

Résumé :

The fast swimming and associated breaching behaviour of endothermic mackerel sharks is well suited to the capture of agile prey. In contrast, the observed but rarely documented breaching capability of basking sharks is incongruous to their famously languid lifestyle as filter-feeding planktivores. Indeed, by analysing video footage and an animal-instrumented data logger, we found that basking sharks exhibit the same vertical velocity (approx. 5 m s −1 ) during breach events as the famously powerful predatory great white shark. We estimate that an 8-m, 2700-kg basking shark, recorded breaching

Résumé :

The response to capture is important in fisheries because it can reveal potential threats to species beyond fishing mortalities resulting from direct harvest. To date, the vast majority of studies assessing shark stress responses have used physiology or biotelemetry to look at sensitivity after capture, leaving a gap in our understanding of the behaviours of sharks during capture. We examined the behavioural responses of sharks to capture by attaching accelerometers to fishing gear and measuring the immediate and prolonged forces they exerted while on the line. We recorded acceleration vectors

Résumé :

Coastal sharks can use shallow, nearshore habitats as nursery areas, which is a behaviour that may increase fitness. The ecological benefits of shark nursery areas are well studied; yet the physiological mechanisms that enable sharks to exploit coastal habitats, especially those that experience extreme and dynamic temperatures, remain understudied. We hypothesised that neonatal sharks are able to use thermally dynamic coastal habitats as nursery areas because temperature does not strongly affect their physiology. To test this hypothesis, we defined patterns of nursery area use and temperature-

Résumé :

The movement rates of sharks are intrinsically linked to foraging ecology, predator–prey dynamics and wider ecosystem functioning in marine systems. During ram ventilation, however, shark movement rates are linked not only to ecological parameters, but also to physiology, as minimum speeds are required to provide sufficient water flow across the gills to maintain metabolism. We develop a geometric model predicting a positive scaling relationship between swim speeds in relation to body size and ultimately shark metabolism, taking into account estimates for the scaling of gill dimensions.

Multimodal sensory input directs simple and complex behaviors in animals. Most research to date has been limited to studies of individual senses rather than multiple senses working together, leading to important advances in our comprehension of the sensory systems in isolation, but not their complementary and alternative roles in difficult behavioral tasks, such as feeding. In the marine environment, a prey item might emit an odor, create a hydrodynamic disturbance, such as from gill movements or swimming, be visible to the predator, produce a sound, and/or produce a weak electrical field.

Fundamental to life is the ability to acquire and assimilate nutrients. Individual cell types exhibit preferences for different nutrients, but only certain cells utilize nutrients as signaling molecules. The most intensely studied nutrient signaling system is the pancreatic beta cell, which secretes insulin in response to changes in blood glucose. Another glucose sensing system is found in the neurons within the hypothalamus of the brain. To study how single cells sense changes in glucose, a sensitive marker for secretion is required.

Résumé :

Longline fishing is the most common elasmobranch capture method in the world, both for commercial fishing, and to a lesser extent for scientific surveys. The capture of an animal on a longline initiates a series of physiological responses designed to promote survivorship in the short term, but if unchecked, can cause reduced individual fitness and/or mortality in the long term. Given widespread declines in shark populations, an improved understanding of the physiological costs of longline capture is needed.

Résumé :

Sharks and rays are among the most threatened aquatic vertebrate taxa. This is due to a combination of their slow generation times, exploitation within the fisheries, and habitat degradation. Climate change was added as an additional, major threat to sharks and rays in the first decade of the 21st century. While marine protected areas are becoming more widespread, managing and conserving sharks and rays is complicated. Yet, the conservation physiology toolbox can be used to address such challenges. Here, we highlight studies from the Physioshark project, a conservation physiology research programme initiated to understand how human-induced stressors, primarily climate change, will affect tropical sharks and rays and the consequences for the health and viability of populations. We also highlight how other research teams from around the world have taken physiological approaches to understanding conservation problems for sharks. We then emphasize the importance of public outreach and education about the conservation issues sharks encounter, the benefits of using social media to disseminate key concepts, publications, presentations, media, and successes, and we underscore the power of storytelling through digital media as an important means for attracting attention to research, which can result in support and action.

Résumé :

Abstract.—To provide a synthesis of the physiological responses to otter-trawl capture in spiny dogfish <em>Squalus acanthias</em>, blood values from trawled individuals were evaluated against values from minimally stressed dogfish caught rapidly by hook and line (control). Values and analyses from published studies are considered along with those from the most expansive set of blood samples taken from dogfish captured by both methods to date. Significant impacts of trawling on dogfish blood physiology were reflected in all parameters excluding log plasma protein. Parameters for whole-blood acid–base status (pH, significant decrease; pO<sub>2</sub>, 45% decrease; pCO<sub>2</sub>, 82% increase), and the metabolite lactate anion (125% increase) were most perturbed relative to differences induced by the capture methods in other parameters. The concentrations of sera monovalent electrolytes (Na<sup>+</sup>, K<sup>+</sup>, Cl<sup>-</sup>) and glucose were significantly elevated by trawling, but not to the magnitude seen in other studies related to capture stress in fish. Significant elevations in hematocrit and reductions in blood urea nitrogen (BUN) concentrations were also observed subsequent to trawling. Overall, this capture method incited marked changes in blood physiology relative to values in minimally stressed dogfish. However, previous studies demonstrating high rates of posttrawl dogfish survival indicate that such changes are resolvable in this species prior to lethal consequences.

The urgency of soybean breeding for increasing resistance to low temperatures is caused by a large share of the arid regions of Moldova, where the increase in productivity can be ensured by carrier earlier plant-ing and ripening periods before the summer droughts peaks. Thus, as a result of the studies carried out, it was found that when germinating seeds at a temperature of 4˚C, selection is stricter and more efficient. Sowing in the early stages is possible, since soybean seeds remain viable at low temperatures, and when the temperature rises, the best varieties reach the germination rate ch

Résumé :

Two of the pillars on which university education is based are the integrated curriculum and transdisciplinarity. The first consists of combining and teaching two or more subjects together, while the second refers to interacting and working as a team with professionals from other areas, to have a 360º vision. This work is the result of a collaboration between teachers from different universities and departments in the area of Health Sciences, who implemented a multimedia material integrating contents of Biology and Physiology, with the aim of promoting the achievement of a more significant know

Résumé :

Abstract A multiple disk centrifugal pump (MDCP) is under investigation as a potential left ventricular assist device. As is the case with most shaft driven pumps, leakage problems around the shaft/shaft-seal interface are of major interest. If leakage were to occur during or after implantation, potential events such as blood loss, clotting, blood damage, and/or infections might result in adverse effects for the patient. Because these effects could be quite disastrous, potential shaft and shaft-seal materials have been investigated to determine the most appropriate course to limit these effect

Résumé :

Despite a large range of surgical options, treatment of patellofemoral instability continues to be a challenging clinical problem. Currently, there have been a number of computer models developed to try and better define the stabilizing forces about the patellofemoral joint. However, most of these studies have focused on patellofemoral contact pressures, omitting evaluation of patellar stability in the first 30° of knee flexion. The purpose of this study was to reconstruct a pathologic and normative patellar shape within a computer model based on previously described morphologic ratios. We the

Résumé :

Hypoplastic left heart syndrome (HLHS) is a leading cause of cardiac death among newborns, in which the entire left side of the heart is underdeveloped and unable to support the blood circulation. It is the most common type of single ventricle physiology (SVP) and an important need for an adjustable systemic to pulmonary artery (SPA) shunt. In order to achieve full range control of blood flow between the systemic and pulmonary circulation, an adjustable SPA shunt is being developed. SPA shunts are generally made from FDA approved polytetrafluroethylene (PTFE). A screw-plunger mechanism is bein

Résumé :

Plant species synthesize a multitude of specialized compounds 10 help ward off pests. and these in turn may well serve as an alternative to synthetic pesticides to reduce environmental damage and health risks to humans. The general goal of this research was to perform a genetic and biochemical dissection of the natural-insecticides methylketone pathway that is specific to the glandular trichomes of the wild species of tomato, Solanumhabrochaites f. glabratum (accession PI126449). Previous study conducted by us have demonstrated that these compounds are synthesized de novo as a derivate pathway
