Abstract:
... Multiple species of shorebirds are now globally threatened, particularly across tropical Asia, yet we know relatively little of the detailed habitat usage and resource characteristics of sites in the region. The objective of this study was to determine how seasonal variation in food density affected foraging patterns and body weights of Long-toed Stint (Calidris subminuta), a relatively common win ...

Abstract:
... Intertidal organisms are exposed to a suite of fluctuating environmental variables, but the relative influences of these variables on physiology have rarely been disentangled. We examined spatial and temporal variation in the enzymatic capacities for ATP generation (malate dehydrogenase [MDH] and citrate synthase [CS]) and for detoxification of reactive oxygen species (superoxide dismutase [SOD] a ...

To validate an adapted instrument that assesses the nutritional environment of food stores in Brazilian urban areas.The instrument measured aspects of food environment such as availability, prices, and quality. The Harvard Healthy Eating Pyramid and the degree of processing were used to define healthy foods. The sample included 44 food stores in 3 census tracts in the city of Santos. Inter-rater r ...

Abstract:
... This review deals with the behaviour of river buffaloes (Bubalus bubalis), in confinement and in extensive conditions, also focusing on the effects of different housing and rearing conditions on their welfare. The behavioural repertoire expressed by buffaloes in extensive and intensive conditions is similar to those displayed by other domestic ruminants. However, through natural selection, buffalo ...

Abstract:
... The structure and composition of Osmia dimidiata nests were studied based on the material of 133 nests obtained from trap-nests in five localities of the Crimea. The nests contained from 1 to 9 cells (on average, 2.2), separated with partitions made of masticated leaves. Most of the cells had a massive hemispherical bottom and a thin flat cover. The final plug had a structure similar to the cell b ...

Abstract:
... We studied the ranging pattern of the wild black-and-white snub-nosed monkeys (Rhinopithecus bieti) at Xiaochangdu, Tibet from June 2003 to March 2005. Using the map grid cell method, the group home range were 16.75 km² in summer, 10.50 km² in winter, and 21.25 km² total over two years. The daily travel length (DTL) averaged 765 m with a range of 350–3500 m. The results showed that DTL in winter w ...

Abstract:
... The “brown shrimp”, Crangon crangon (Linnaeus 1758), is a benthic key species in the North Sea ecosystem, supporting an intense commercial fishery. Its reproductive pattern is characterized by a continuous spawning season from mid-winter to early autumn. During this extended period, C. crangon shows significant seasonal variations in egg size and embryonic biomass, which may influence larval quali ...

Parameters of moult (start date, duration, and standard deviation) and how they are affected by rainfall patterns were estimated using and extension of the Underhill—Zucchini (1988) moult models which all ...

Abstract:
... Spatial and temporal variation in resource abundance and predation risk can favor the evolution of phenotypic plasticity as a means of tracking changing environments. However, because food abundance and predation risk often covary in nature, few studies have separated their effects or tested whether different phenotypic traits respond to the same sources of environmental variation. We investigated ...
