Brood

 

the young members of a family of birds or mammals (hatchlings, litters). Sometimes the term also refers to the offspring and both parents or one (in polygamous species). The number of young animals in the brood or litter varies greatly from species to species, depending upon their fertility; for example, birds can have from one to 24 hatchlings, and mammals can have from one to 20 young. Even within one species the number of young can vary; in particular, it depends upon the climatic conditions of the year and other such factors.

teleta have examined effects of reduced salinity on larval survival, juvenile growth, and reproductive success (Pechenik et al., 2000, 2001a, b), none has examined the impact of salinity stress or hypoxia on the development of brooded embryos, or the later consequences of such stress.
1), no larvae successfully emerged from any brood tubes after brooded embryos had been exposed to that salinity for 48 h or 96 h (Fig.
But, as yet, of my 12 Wyandotte pullets, only the one persistent pullet has brooded. If anybody has developed a nest design or method that encourages brooding, I would appreciate any information or tips.
For instance, brooded embryos may die due to failed embryogenesis and/or fertilization (Kuris 1991), parasites (Shields et al.
About one week after a filled brood chamber was observed, the total number of chambers and the number of brooded embryos per colony were recorded.
Total number of larvae brooded (total larval production) on each sampling date along the season showed a high correlation with brooding percentages ([r.sup.2] = 0.85) being the highest value found on December 21 (Fig.

In some species, however, there is a totally benthic or brooded larval development, and in other cases a period of brooding is followed by a pelagic phase (Pechenik, 1979, 1986).
Relationships between percent mortality and features of the mother (female size = drained weight, number of pentactulae brooded) were tested by combining data from Sites 1 and 2 for each month.
Although originally proposed for an external brooder (Strathmann and Strathmann, 1982), the allometry hypothesis has been tested by comparing the relationship between animal size, egg number, and number of brooded embryos in several marine invertebrates (Daly, 1972; Rutherford, 1973; Menge, 1974; Ockelmann and Muus, 1978; Rumrill, 1982; Strathmann et al., 1984; Kabat, 1985; Gremare and Olive, 1986; McGrath and OFoighil, 1986; Russell and Huelsenbeck, 1989; Byrne, 199 1; Brev and Hain, 1992; Hines, 1992; Hess, 1993).
