“…The paradox of stress lies in the simultaneity of its adaptive nature and its possible maladaptive consequences [13,14]. The best known stress hormones are corticosteroids, but their name could also be anti-stress hormones [15], because their primary function is protective and adaptive [16][17][18]. Corticosteroids are well known for their inverted-U curve of concentration and effect [16] (see also Fig 1).…”

“…This response, involving the release of mediators of allostasis (e.g. adrenal hormones, neurotransmitters, and cytokines (see Table 2)), works via receptors in various tissues and organs to produce changes that are adaptive to metabolism, immune, and cardiovascular systems in the short term [11,13,14,17,22,29,30].…”

Moreover, the irreversible nature of changes in reactivity, reduced resilience and consequently the damage to tissues and organs can be used as a measure of allostatic load [12][13][14]17,28,29]. See also Table 2 for the different types of allostatic load due to hypostimulation or hyperstimulation.…”

Animal welfare is an increasing issue of public concern and debate. As a result, many countries are reconsidering the way animal welfare is embedded in the legislation and rules for housing and care of animals. This requires general agreement of what animal welfare is. Unfortunately, the current science of animal welfare is less scientific than what has been claimed. In our view, it is overly guided by anthropocentric thinking about how animals ought to be handled and neglects the latest concept of physiology: 'The Allostasis Concept'. Allostasis, which means stability through change, has the potential to replace homeostasis as the core model of physiological regulation. Not constancy or freedoms, but capacity to change is crucial to good physical and mental health and good animal welfare. Therefore, not homeostasis but allostasis is at the basis of our new animal welfare concept. This paper is aimed at a broader scientific discussion of animal welfare that includes knowledge from the latest scientific developments in neurobiology and behavioral physiology, and generates views that are extremely relevant for the animal welfare discussion.

“…The steroid hormone corticosterone (CORT) plays an important role in an individual's adaptive response to environmental stress (Romero et al, 2000;Wingfield et al, 1998). Individuals have been shown to respond to a number of stressors such as challenging environmental conditions, parasites, and predators by increasing secretion of CORT (e.g., Raouf et al, 2006;Romero et al, 2000).…”

Does location really matter? An inter-colony comparison of seabirds breeding at varying distances from productive oceanographic features in the Bering Sea

a b s t r a c tCentral place foragers, such as breeding seabirds, need to commute between their nests and foraging grounds, thus close proximity of the breeding colony to productive oceanographic features might be beneficial for seabird reproduction. We tested this hypothesis by investigating the at-sea foraging and breeding behavior of thick-billed murres (Uria lomvia) nesting at three colonies (Bogoslof, St. Paul, and St. George Islands) in the Bering Sea located at different distances from the productive continental shelf-break. We found that distances to feeding areas differed only during night trips among colonies. St. Paul murres foraged entirely on the shelf, whereas St. George murres commuted to the continental shelf-break at night and foraged on the shelf during the day. Bogoslof murres foraged in oceanic waters in close proximity to the colony. Murres breeding at the both Pribilof colonies spent less time attending nests and had higher levels of stress hormone corticosterone compared to murres breeding at Bogoslof, although chick-provisioning rates and fledging success were similar among the three colonies. Lower nest attendance and higher corticosterone suggest lower food availability in the Pribilof domain compared to the Bogoslof region. Murres breeding at the Pribilofs used different foraging strategies to buffer effects of food shortages on their reproduction: flight costs associated with longer distance night trips at St. George were presumably balanced by benefits of higher density and/or more lipid rich prey in the continental shelf-break regions, whereas the additional distance of St. Paul from the continental shelf-break may have outweighed any energetic gain. Murres exhibited a remarkable degree of plasticity of foraging strategies in response to changes in their food availability, but the breeding success of murres did not reflect either food limitations or the colony proximity to productive oceanographic features.

“…As condições climáticas como a temperatura também são responsáveis por influenciar os níveis de corticosterona nas aves, modulando o acúmulo de gordura e o mecanismo de regulação da glicose, importantes fatores para sua sobrevivência (Romero et al, 2000;Ben-Hamo et al, 2013). Apesar da temperatura (máxima e mínima) e irradiação solar estarem visualmente correlacionadas às espécies do segundo e quarto quadrantes da Fig.…”

ABSTRACT. Composition and dynamics of birds of the wind farm of the beach of the Pedra do Sal, Delta do Parnaíba, Piauí, Brazil. The impact of wind farms on birds is one of the least studied themes in Brazil, which contrasts with the importance of this new source of renewable energy. The present study aimed to characterize the composition and ecological dynamics of species of resident and migratory birds present in the area of Wind farm of the Pedra do Sal, in Parnaíba, state of Piauí. The study was developed through thirty-three samples distributed in two complete seasonal cycles (September 2011 to August 2013, by the method of point counts disposed at the base of each wind turbine. We recorded 6,843 contacts of birds belonging to 67 species in 22 families and 13 orders, and the species with the highest number of contacts was the Charadrius collaris Vieillot, 1818. The predominant trophic categories were the insectivorous birds (18 species) followed by birds that feed on aquatic invertebrates (17 species). The majority of birds recorded is from aquatic environments. During the development of this study, no collisions between birds and wind turbines were recorded.

RESUMO.O impacto dos parques eólicos sobre as aves é um dos temas menos estudados no Brasil, o que contrasta com a importância dessa nova fonte de energia renovável. O presente estudo buscou caracterizar a composição e dinâmica ecológica das espécies de aves residentes e migratórias presentes na área da Usina Eólica da Pedra do Sal, em Parnaíba, Estado do Piauí. O estudo foi desenvolvido por meio de trinta e três amostragens distribuídas em dois ciclos sazonais completos (setembro de 2011 a agosto de 2013), através do método do ponto de escuta, dispostos na base de cada um dos aerogeradores. Foram registrados 6.843 contatos de aves pertencentes a 67 espécies distribuídas em 22 famílias e 13 ordens, e a espécie com maior número de contatos foi a batuíra-de-coleira (Charadrius collaris). As categorias tróficas predominantes foram as das aves insetívoras, representadas por 18 espécies, seguidas pelas aves que se alimentam de invertebrados aquáticos (17 espécies). A maioria das aves registradas é de ambiente aquático. Durante o desenvolvimento desse estudo não foram registradas colisões entre as aves e os aerogeradores.
