Cuckoo Search via Lévy flights

World Congress on Nature and Biologically Inspired Computing, 2009
In this paper, we intend to formulate a new meta-heuristic algorithm, called Cuckoo Search (CS), for solving optimization problems. This algorithm is based on the obligate brood parasitic behaviour of some cuckoo species in combination with the Lévy ...

Infertility in the brood mare?

New Zealand Veterinary Journal, 1982
This communication describes the methods used and results obtained with a 21-year-old Standardbred sire bred, using artificial insemination techniques, to a book of 108 mares during the period 11th September to 16th March, 1979-80. A positive pregnancy test rate of 93.5% was achieved.

Brood parasitism

, 2012
Whenever parents provide care they are vulnerable to exploitation by brood parasites (Fig. 13.1). Brood parasitic offspring have no evolutionary interest in their foster siblings, or in their foster parents’ residual reproductive value.

Giant Babaxes mix brood reduction and brood survival strategies

Journal of Ornithology, 2011
Altricial birds may vary their relative reproductive investment at the egg versus nestling stages as an adaptive strategy to deal with variable or unpredictable food availability between stages. We investigated the parental investment strategies of Giant Babax (Babax waddelli) breeding in a harsh, high-altitude environment on the Tibetan plateau.

The Brood Nest

1986
As in many other areas of husbandry, the ancient truths of apiculture collect like cliches and grow into aphorisms. Thus, it is widely known that honeybees expand their nests with the warmth of spring and its abundance of nectar and fresh pollen for the rearing of brood (Butler 1609).

Parental care in burying beetles: the organization of male and female brood-care behavior.

, 2010
Parental care in the burying beetle Nicrophorus orbicollis was studied by comparing the composition of male and female repertories and time budgets and by analyzing the pairwise transition frequencies of brood-care acts performed by each sex.

Flexibility in the Foraging Behavior of Blue Tits in Response to Short‐Term Manipulations of Brood Size

, 2010
Previous work suggests that short-term changes in feeding rate are usually produced by the parent-offspring interaction. However, few studies have properly tested this assumption. In this study, we attempt to explore the short-term consequences of daily (

Brood Size, Male Fanning Effort and the Energetics of a Nonshareable Parental Investment in Bluegill Sunfish, Lepomis macrochirus (Teleostei: Centrarchidae)

, 2010
We present a model and an experimental test for a nonshareable parental-investment behavior (fanning of eggs) using parental male bluegill sunfish. The model predicts that as brood size increases, nonshareable investment into the brood should increase if
