1. Earlier sex change in infected individuals of the protogynous reef fish Thalassoma bifasciatum

Author:

Subject:
Kudoa; Thalassoma; eggs; females; fish; parasites; prediction; protogyny; sex allocation; sex reversal
Abstract:
... Sex allocation theory for sequential hermaphrodites predicts the size at which an individual should change sex, given the different relationships between individual size and reproductive success in the two sexes. We studied a host-parasite system where the myxozoan Kudoa ovivora infects the ovaries of the reef fish Thalassoma bifasciatum, a protogynous sequential hermaphrodite. The parasite sporul ...

2. Electrosensory basis for individual recognition in a weakly electric, mormyrid fish, Pollimyrus adspersus (Günther, 1866)

Pollimyrus; fish; sense organs
Abstract:
... Pollimyrus adspersus discriminates the individually variable waveforms of Electric Organ Discharges (EODs) of conspecifics of only 150–250 μs duration. We examined: (1) the discrimination threshold for artificially generated EODs of similar waveform, (2) the mechanism of signal analysis (spectral vs temporal) present, by determining the discrimination between different waveforms of identical ampli ...

Abstract:
... The ability to discriminate between more dangerous and less dangerous predators can have serious fitness advantages for fish juveniles. This is especially true for hatchery-reared fish young used for stocking, because their post-release mortality is often much higher than that of wild-born conspecifics. We tested whether two coexisting fish predators and their different diets induce innate behavio ...

Abstract:
... Behavioural variation is known to occur between individuals of the same population competing for resources. Individuals also vary with respect to their boldness or shyness. An individual’s position along the shy-bold axis may be defined as the extent to which it is willing to trade off potentially increased predation risks for possible gains in resources. Similarly, group living may be interpreted ...

Abstract:
... Guppies are highly sexually dimorphic. Females have been shown to mate preferentially with males with various visible traits and previous studies investigating mate choice have focussed on these visual cues. However, guppies have been shown to respond behaviourally to odour cues from conspecifics as well as from predators. Therefore, sexual selection in guppies may act on multiple sensory modaliti ...

Abstract:
... Filial cannibalism is hypothesized to allow nest-guarding males to recoup energy lost during nest defense. Males in many species of fishes occasionally defend broods containing both sired and foster eggs due to shifts in nest site ownership or cuckoldry. Such males are predicted to consume primarily foster eggs if the ability to discriminate among eggs exists. In a previous laboratory study, male ...

Abstract:
... Sex change in marine teleost fishes is commonly regulated by social factors. In species that exhibit protogynous sex change, such as the bluebanded goby Lythrypnus dalli, the most dominant female typically initiates sex change when a male is removed from the social group. Females can use visual, chemical or tactile cues to assess the presence or absence of a male. The primary goal of our study was ...

Abstract:
... Sexual selection in most vertebrates is based on the evolution of fitness optimization strategies such as multiple-male mating (MMM). Several ecological correlates of MMM have been identified in bird and fish populations; however, only few studies have documented the effects of environmental change on promiscuity in mammals. In this study, the 127 pregnant females from four central European and ec ...

Male water striders (Aquarius remigis) vary widely in their aggressiveness toward pursuing females. The most aggressive males prevent females from feeding and cause ...

Additionally, shoaling leads to increased predator confusion. This “confusio ...

We studied the effect of sperm quality and number on competitive fertilization success in an internal-fertilizing fish, the guppy (Poecilia reticulata), which is characterized by h ...

Abstract:
... Despite the central role that female mate choice plays in the production of biological diversity, controversy remains concerning its evolution and maintenance. This is particularly true in systems where females are choosy but do not receive obvious direct benefits such as nuptial gifts that increase a female's survival and fecundity. In the absence of such direct benefits, indirect benefits (i.e., ...

The diel movement patterns of French grunt, a common Caribbean coral reef fish, are well documented and known to connect reef and seagrass habitat.
