Abstract. Most blennioid fishes show a resource-based, promiscuous mating system with alternative 'sneaking' mating tactics. The hole-nesting species, Aidablennius sphinx, however, appears to be an exception; small males did not mimic females, most had their own nest and not once in 20 h of spawning observations did a second male enter a nest. In this field study, we ask if sneaker tactics are constrained and what factors favour independent nesting by small males. Larger males received more… 

Reproductive allocation in Aidablennius sphynx (Teleostei, Blenniidae): females lay more eggs faster when paired with larger males.

Female reproductive responses to large and small males were investigated and it was found that when paired with large males, females spawned more eggs per unit time and by ovipositing at a faster rate, females may have allocated more reproductive effort to large males.

Size-assortative nest preference in a paternal brooding blenny Rhabdoblennius ellipes (Jordan & Starks)

Aquarium nest choice experiments without a competitive male strongly suggested that the size-assortative nest use by males is not the result of male–male competition for larger nests, but male preference for size-matched nests.

Sexual dimorphism and male mating success in the tentacled blenny, Parablennius tentacularis (Teleostei: Blenniidae)

Support is provided for a primary role of male ornaments in enhancing blenny male mating success and is discussed in the context of mate choice for direct and indirect benefits.

Sperm investment and alternative mating tactics in bluegill sunfish (Lepomis macrochirus)

These sperm investment patterns of males that use alternative mating tactics in bluegill sunfish are interpreted in relation to differences in sperm competition risk, number of mating opportunities, and alternative investment options.

Differential Space Utilization by Male and Female Spinyhead Blennies, Acanthemblemaria spinosa (Teleostei: Chaenopsidae)

Corals originally harboring larger fish were recolonized at a higher rate, and in all cases the mean size of recolonist was smaller than originals; the original correlation of fish size with height above the reef surface collapsed for recolonists.

Cuckoldry rates in the Molly Miller (scartella cristata; blenniidae), a hole-nesting marine fish with alternative reproductive tactics

Estimated cuckoldry rates in this population of the Molly Miller are compared to those previously reported for local populations in other nest-tending fish species, with results discussed in the context of ecological and behavioral variables that may influence relative frequencies of nest parasitism.

Does exaggerated morphology preclude plasticity to cuckoldry in the midshipman fish (Porichthys notatus)?

The “exaggerated” morphology need not preclude adaptive plasticity to cuckoldry, and may even aid it, according to a field and aquarium study of the midshipman fish, a fish with both exaggerated and reduced morphs.

Synchronous Female Spawning and Male Mating Behavior in a Land-Locked Population of Japanese Charr, Salvelinus leucomaenis japonicus

In this Japanese charr population, the synchronous spawning of females was related to the unbiased daily OSR, male aggregation around females, and consequently whether and how efficiently males engaged in sneak mating behavior is concluded.

A Quantitative Assessment of the Reproductive System of the Mediterranean Cave‐Dwelling Triplefin Blenny Tripterygion melanurus

The breeding biology of the cave-dwelling Mediterranean triplefin blenny Tripterygion melanurus (Pisces, Blennioidei) was studied in the field and the possibility that territorial males tolerate the proximity of other territorial males and accept a risk of cuckoldry is discussed.

Female within-nest spawning-site preference in a paternal brooding blenny and its effect on the female mate choice

Female spawning-site preference within a nest and its effect on the female mate choice in a paternal brooding blenny Rhabdoblennius ellipes, were examined in rocky intertidal pools using artificial nests indicated that females prefer to spawn eggs in the center and deep sites rather than at the entrance site.



Male and female mate choice in the redlip blenny: why bigger is better

Male mating success in the Azorean rock‐pool blenny: the effects of body size, male behaviour and nest characteristics

The present data suggest strongly that male characteristics overrule nest characteristics in determining male mating success in the Azorean rock-pool blenny.

Mate Choice in Aidablennius Sphynx (Teleostei, Blenniidae); Females Prefer Nests Containing More Eggs

It is discussed that female preference for large broods might be adaptive because the number of eggs present in the nest is probably a reliable predictor of the survival chances of the eggs.

Mutual mate choice in sticklebacks: attractive males choose big females, which lay big eggs

It is proposed that this can explain how brightness can be sexually selected in spite of brighter males not receiving more eggs, and in nature this preference for bigger females results in brighter males receiving on average heavier eggs.

Female sand gobies gain direct benefits by choosing males with eggs in their nests

Female preference for males with eggs in their nests is adaptive, and can be explained by direct benefits, as more surviving offspring are produced.

Females prefer mating males in the carmine triplefin, Axoclinus carminalis, a paternal brood-guarder

A preference for mating males or males that are guarding eggs could provide asymmetric benefits for males to defend oviposition sites, and this preference for males with eggs could be acting alone or with other factors such as high variance in Oviposition site quality to favor the evolution of paternal care in fishes.

Male limitation of female reproductive success in a pipefish: effects of body-size differences

It was predicted that male limitation of female reproductive success is even more severe when all age classes are considered, and it was found that small females are more severely constrained by mate availability than are larger females because males choose to mate with larger females.

Mating system and spawning cycle in the blenny,Istiblennius enosimae, at Kagoshima, Japan

It was suggested that this semilunar spawning cycle guarantees a maximum dispersal of newly hatched embryos away from natal tidepool, and there is a size-assortative relationship between male and female among pairs.
