“…Clutches were much more conspicuous in the two former species and egg condition is known to be a cue for male quality (Sikkel, 1995;Manica, 2010). In C. multilineata a series of female visits to a male nest were described to happen one after the other in a short interval (Myrberg et al, 1967), what we also observed in São Paulo. Therefore, eggs are probably not used by females to choose partners and paternal care is less interesting in terms of sexual selection.…”

“…Other species from the genus Chromis have been described as territorials and paternal (Fishelson, 1970;Tzioumis & Kingsford, 1999). Even C. multilineata, in reefs where Sargassum were less abundant, defended algae tuffs and guarded them after spawning (Myrberg et al, 1967). It is important to mention that S. fuscus territoriality is similar to A. saxatilis' during the reproductive period only.…”

“…Only one female of Stegastes fuscus and no Chromis multilineata were collected. The same treatment given to A. saxatilis was done to S. fuscus but further data for C. multilineata and S. fuscus iteroparity were taken from literature (Myrberg et al, 1967;Souza et al, 2007). Observing how distended the visiting females' abdomens were after they left the nest, as commonly used in aquaculture (Woynarovich, 1989), offered an indirect and complementary approach to the presence of iteroparous females in the study area.…”

“…Male and female Stegastes fuscus were identified by accompanying a marked nest previously filled with eggs (Since only males guard the eggs; Souza et al, 2007) or by their courting behavior. Chromis multilineata could be sexed by the presence of a swallowed genital papilla in females (Myrberg et al, 1967;Swerdloff, 1970).…”

ABSTRACT. Paternal care is rare in most animals, but common in fishes, including Pomacentridae. One way of explaining it is through the territorial hypothesis, which predicts that paternal care may evolve when caring for a territory with eggs will not cost more than territories without eggs. Here we describe the reproductive behavior of three pomacentrids from São Paulo, Brazil, and evaluate if the territorial hypothesis explains their behavioral variation through five predictions. We checked if females have multiple spawns (prediction 1), if they forage more (prediction 2) and if territory defence demands more when eggs are present (prediction 3). We also described how visible eggs are (prediction 4) and how available nesting sites are (prediction 5). Chromis multilineata differed from Abudefduf saxatilis and Stegastes fuscus by not guarding the eggs, spending less time with territoriality and fanning eggs; and more time feeding and foraging. Females of the three species are iteroparous. Females' A. saxatilis and S. fuscus foraged more than males, which spent the same amount of time in territorial defence before and after eggs were delivered. These two species also have very conspicuous egg clutches on clean rock surfaces defended by them. On the other hand, males and females of C. multilineata spent the same time foraging, while territoriality took more effort after eggs were present and it spawns cryptic eggs amid Sargassum, a common and disperse micro-environment in São Paulo rocky shores. Territorial hypothesis explains why paternal care by A. saxatilis and S. fuscus lasts longer than by C. multilineata.

El cuidado paterno es raro en la mayoría de los animales, pero común en los peces, incluyendo los Pomacentridae. Una forma de explicar este fenómeno es la hipótesis territorial, que predice que el cuidado paterno puede evolucionar cuando la protección de un territorio con huevos no cuesta más que la de territorios sin huevos. Aquí se describe el comportamiento reproductivo de tres pomacentrídios de São Paulo, Brasil, y se evalúa si la hipótesis territorial explica la variación de su comportamiento a través de cinco predicciones. Se analizó si las hembras tienen múltiples desoves (predicción 1), si forrajean más (predicción 2) y si la defensa del territorio es mayor cuando los huevos están presentes (predicción 3). También se evaluó si los huevos eran visibles (predicción 4) y cuán disponibles eran los sitios de anidación (predicción 5). Chromis multilineata difería de Abudefduf saxatilis y Stegastes fuscus por no proteger a sus huevos, dedicar menos tiempo a la territorialidad y ventilación de sus huevos, y más tiempo para la alimentación y forrajeo. Las hembras de las tres especies son iteróparas. ...

The term “aggression” has been used to describe practically all situations in which an organism threatens, damages, or kills another‐with the exception of certain predator‐prey relationships. As a result, a great deal of confusion and controversy has arisen as to the causal factors and functions of aggression. The main ethological hypotheses concerning the nature of aggression are put forward. In order to illustrate the divergence in causal factors and functions, differences in motivational, physiological, and ecological bases of aggression in two closely related fish species are described. A basic division of aggression into “self‐defensive” and “property‐protective” behavior is suggested, together with the parameters separating these categories on behavioral, causal, and functional bases. Mechanisms which enable motivational changes from one category to another to take place during a single encounter are discussed, these being pain stimuli and physical or psychological “cornering.” The importance of learning effects on fighting behavior are emphasized, especially their negative and positive reinforcing effects in relation to self and property defense. The biological significance of aggressive conditioning for the animal and the role of aggression in species maintenance are discussed.
