Understanding the movement patterns of fishes in the wild requires an awareness of the intrinsic and extrinsic factors underlying their behaviour. Using field observations, we explored whether eight species of coral reef fish display modality in their swimming behaviour, which is a convergence in fin use patterns among and within species when they ...

The structure and ultrastructure of the photoreceptors of several life history stages of the ontogenetically migrating lophogastrid crustacean Gnathophausia ingens were examined. The younger instars of this species live in a much brighter light field than the older instars, and this difference is reflected in differences in their visual systems. Th...

BackgroundThe evolution of barriers to reproduction is of key interest to understand speciation. However, there may be a current bias towards studying intrinsic postzygotic isolation in old species pairs as compared to the emergence of barriers to gene flow through adaptive divergence. This study evaluates the relative importance of both processes ...

The foraging behaviours and dietary compositions of three co-occurring labrids (Ophthalmolepis lineolatus, Notolabrus gymnogenis and Pictilabrus laticlavius), which are conspicuous on rocky reefs in temperate south-eastern Australia, were investigated between 2003 and 2005. SCUBA observations at two locations showed that the feeding intensity, and ...

BackgroundScleractinian corals are the foundation of reef ecosystems in tropical marine environments. Their great success is due to interactions with endosymbiotic dinoflagellates (Symbiodinium spp.), with which they are obligately symbiotic. To develop a foundation for studying coral biology and coral symbiosis, we have constructed a set of cDNA l...

Offspring size can have pervasive effects throughout the life history stages of many marine invertebrates. Although maternal offspring investment is largely determined by the environmental conditions experienced by the mother, egg size might additionally vary in response to the number and quality of previous mating partners. Positive effects of mat...

Many organisms survive stressful conditions through a tolerant life history stage. The life history known as the alternation of generations is typical of temperate kelps, producing diploid macroscopic stages, and both haploid and diploid microscopic stages, with the haploid stages thought to be stress tolerant. The survival of microscopic stages of...

The productivity of inbred buckwheat lines I1–I8 with the homostyly gene of Fagopyrum esculentum and Fagopyrum homotropicum is studied. The species F. homotropicum is recommended for use in buckwheat breeding as a donor of homostyly and tolerance to inbreeding depression.

Life cycles of birds and other vertebrates are composed of series of life history stages each with unique combinations of morphological, physiological and behavioral characteristics. For example, in the white-crowned sparrow, Zonotrichia leucophrys, the nonbreeding stage (winter), vernal migration, breeding, moult and autumn migration stages occur ...
