Abstract:
AbstractInjury-released chemical alarm cues are released when predators attack aquatic prey. These cues are generally released only in this context and as such, conspecific alarm cues form an important component of risk assessment. Minnows (Ostariophysi, Cyprinidae) possess a well-developed chemical alarm system. However, minnows do not respond to conspecific injury-released alarm cues until 30 to 50 d post-hatch. Non-ostariophysan fishes respond to chemical alarm cues with antipredator behavior but the ontogeny of this behavior is not known for any species. Here, we test convict cichlids (Aca

Abstract:
Social animals with hierarchical dominance systems are susceptible to changes their environment. Interactions with conspecifics can greatly affect individual’s behavior and reproductive success. This review will show how social behavior modulates gonadal steroidogenesis and spermatogenesis in African and Neotropical cichlid fish with different social systems and how this modulation regulates reproductive capacity. Social behavior and aggressiveness are strongly linked to sex steroids, glucocorticoids and neuropeptides. The challenge hypothesis suggests that behavioral interactions increase and

Abstract:
In many biparental species a sex difference in parental investment in a brood before fertilization, such as establishing a breeding territory or preparing a nest, may be an important component of the overall pattern of parental investment. Prefertilization investment patterns have been described for several species of biparental cichlid fishes, but there are discrepancies in the descriptions for the convict cichlid, Cichlasoma nigrofasciatum.

Abstract:
Parental care theory predicts that investment in current reproduction should be increased when the prospects of success in current reproductive effort are relatively high, and reduced when they are poor relative to expected success from future reproductive effort. A number of studies have shown that levels of postspawning parental investment (brood defence, parents' willingness to risk predation) increase when the brood is augmented. However, few studies have shown a change in pre-spawning (gonadal) investment in response to indirect indicators of reproductive success, such as nest site qualit

Abstract:
Convict cichlids (Cichlasoma nigrofasciatum) exhibit extended biparental care of their young. Parents will adopt unrelated (foreign) conspecific young of similar size to or smaller than their own but reject larger foreign young. Adoption of smaller foreign young may benefit the parents by reducing loss of their own young to predators by the dilution effect, which may be enhanced by differential predation on the smaller young. Another factor influencing adoption is that larger foreign young may pose a direct predatory threat to the host parents' young. Measures of aggression among free-swimming

AbstractCichlasoma panamense is a biparental, substrate-spawning cichlid which breeds during the dry season in Panamanian streams. In one population some males helped to defend their offspring throughout the period of parental care but many deserted their mates to achieve additional spawnings leaving females to guard alone. The proportion of C. panamense guarding in pairs increased throughout the breeding season. This was associated with an increase in the rate with which parental cichlids attacked potential brood predators and an increase in brood size. The increase in attack rate was due to

Because biparental convict cichlids (Amatitlania nigrofasciata) typically switch mates, exhibiting serial monogamy, we tested for the costs associated with forcing individuals to remain with the same mate. Convict cichlids were observed over two successive breeding bouts, either with the same or a new, equally experienced, mate.

The allocation of energy into defense behaviours and elevated activity levels, combined with a voluntary reduction of food consumption, represent an investment in the current brood which could (

Abstract:
AbstractC. nigrofasciatum typically breed in monogamous pairs with biparental care of the young for up to 6 weeks. In experimental ponds in southern Canada and streams in north-western Costa Rica two variations on this system were studied: male desertion followed by maternal care, and simultaneous bigamy by males. In the ponds, with a female-biased sex ratio, males deserted or became bigamous when their broods were at all stages from eggs to advanced, free-swimming fry. These departures from monogamy did not consistently influence brood survival, except that broods deserted by their father sho

Abstract:
The diversity of mating systems among animals is astounding. Importantly, similar mating systems have evolved even across distantly related taxa. However, our understanding of the mechanisms underlying these convergently evolved phenotypes is limited. Here, we examine on a genomic scale the neuromolecular basis of social organization in cichlids of the tribe Ectodini from Lake Tanganyika. Using field-collected males and females of four closely related species representing two independent evolutionary transitions from polygyny to monogamy, we take a comparative transcriptomic approach to test t
