“…Nothing is currently known regarding signalling types other than visual signalling in Nothobranchius mate choice but in other fish taxa olfactory and auditory cues play important roles. Chemical communication occurs within a reproductive context in Neotropical annual killifish (Passos et al, ) and may play a role in Nothobranchius communication as well.…”

African annual fishes from the genus Nothobranchius are small teleosts that inhabit temporary water bodies subject to annual desiccation due to the alternation of the monsoon seasons. Given their unique biology, these fish have emerged as a model taxon in several biological disciplines. Their increasing popularity stems from the extremely short lifespan that is the result of their specific life-history adaptations and is retained under laboratory conditions. Nothobranchius furzeri, the most popular laboratory species, is the vertebrate species with the shortest lifespan recorded in captivity. In the laboratory, adults of different Nothobranchius species and populations live between 3 and 18 months and, notably, there is a negative correlation between the captive lifespan of a species and the aridity of their habitat. Their short lifespan is coupled to rapid age-dependent functional decline and expression of cellular and molecular changes comparable to those observed in other vertebrates, including humans. The recent development of transgenesis in this species makes it possible to insert specific constructs into their genome, and the establishment of transgenic lines is facilitated by their very rapid generation time, which can be as short as 1 month. This makes Nothobranchius species particularly suited for investigating biological and molecular aspects of ageing and ageing-associated dysfunctions. At the same time, they also represent a unique model taxon to investigate the evolution of life-history adaptations and their genetic architecture. We review their natural history, including phylogenetic relationships, distribution in relation to habitat conditions and natural selection for differential longevity, population structure and demography, and life cycle with emphasis on diapause that may occur at three stages during embryonic development. We further critically evaluate their use as a laboratory model for understanding the evolution of a rapid ageing rate and its consequences for other life-history traits, for cellular, molecular and integrative traits associated with the ageing process, high incidence of neoplasias, their utility for genome-wide gene-expression studies, and as a model for quantitative genetics. We summarize recent achievements in fostering Nothobranchius species as a widely applicable model system, including an annotated transcriptome, successful transgenesis, and existence of viable inbred lines. We compare the conditions they experience in the wild and in captivity and suggest that they are an ideal taxon to investigate natural genetic variation in a laboratory setting. We conclude that Nothobranchius species -and N. furzeri in particular -could become a unique model taxon that bridges interests in ecological and biomedical research. We hope that a conceptual and methodological integration of these two branches of biology will provide important new insights.

“…Indeed, a recent study [38] suggested that the high conservancy in the sequence of courtship displays among species of Austrolebias is involved in avoiding hybridization. Moreover, a recent study demonstrates that A. reicherti responds to chemical cues of potential mates and suggest that chemical cues are essential in the muddy ponds in which this species reproduces [39].…”

Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life. Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the key to the survival of the species. Most of the available data on Neotropical annual fishes derive from studies on the genus Austrolebias. Herein, we review and summarize the available data on the evolution, reproduction strategy, developmental biology and conservation status of these Neotropical fishes.

“…There may have been other signals the choice fish produced that overtook the visual signal such as olfactory or auditory cues. While visual cues have been used in various mate choice experiments in fishes, experiments looking at olfactory, auditory and multimodal cues with respect to choice are becoming more common (Guevara-Fiore et al,2010;Verzijeden et al,2010;Ronald et al,2012;Passos et al, 2013;Estramil et al,2014).…”

“…Olfactory cues have been shown to play a role in finding a receptive mate especially in turbid waters (Guevara-Fiore et al,2010;Passos et al, 2013). GuevaraFiore et al (2010) found that male guppies increase searching behavior when presented with olfactory cues of receptive females.…”

“…T. meeki can be found in waters that vary in turbidity and have been shown to increase the brightness of their coloration when in more turbid waters (Neil, 1984a;Soria-Barreto & RodilesHernández, 2008). It is possible that they also use other cues in these instances as well since olfactory and auditory signals are easier to transmit through turbid water than visual signals (Endler, 1992;Passos et al,2013).…”
