“…These very important qualities that characterize the development of juveniles in substrate brooding are excellent examples of ecomorphological evolution. Pioneering studies in this field were initiated by Kryzhanowski and other Russian investigators (Smirnov et al, 1995). Development in tilapias can, in fact, be compared to development in altricial and precocial birds: for example, in the order of ploverrelated species, the gulls are altricial and the plovers are precocial.…”

Using light and electron microscopy and fluorescent probes, we followed the ontogenesis of selected organs in embryos of several species of tilapia (Cichlidae, Pisces) with emphasis on chloride cell differentiation in species with two different reproductive styles: we compared the substrate-brooder Tilapia zillii and the mouth-brooders Oreochromis niloticus, O. aureus, Sarotherodon galilaeus, and Tristramella sacra. In all species a transitory blood network system nurtured by the vena caudalis inferiores supplied the yolk sac and preanal finfold during the advanced stages of embryonic and initial stages of larval development. During these stages chloride cells occurred on the yolk sac, as a part of the abdominal epithelium. The cells and their associated blood plexus remained active here until the gill-lamellae, operculum, and mouth became functional. The chloride cells of their epithelium and blood system then took over, concomitant with a gradual degradation of the transitory blood system on the yolk sac. Ontogenesis of these systems (transitory and permanent) progressed at a higher rate in substrate-brooders than in mouth-brooders and was correlated with the earlier functioning of the gill-operculum system. Thus, at a constant temperature of 26 degrees C, the more exposed T. zillii progeny completed metamorphosis at 7-8 days after fertilization, calculated around 5,000 +/- 80 h/temp, whereas juveniles of more protected mouth-brooders attained a similar stage only 15 +/- 1 days after fertilization and around 9,000 +/- 200 h/temp. This earlier development of chloride cells and other pivotal organs in environmentally exposed progeny of substrate-brooders, as compared to the protected progeny of mouth-brooders, shows that their ontogeny was selected for the optimal survival style under specific etho-ecological conditions.

“…This is testified by the large number of comparative ontogenetic and eco-morphological studies carried out in Russia, North America and Europe (e.g. Smirnov et al 1995;Balon 1999;Copp et al 1999). Conversely, in other parts of the world (hence, schools of thought), such as Australasia, only a few studies have relied so far on the AODP framework (Vilizzi 1998a(Vilizzi ,b, 2010Humphries 2005), in spite of advice in favour of this approach (Serafini and Humphries 2002).…”

Alternative ontogenies and developmental plasticity: implications for ecological and evolutionary studies on species complexes

According to modern evolutionary biology, for understanding ontogenetic (i.e. early development) processes, it is necessary to focus on the interactions between genotype and developing phenotype, that is on both genetic and developmental epigenetic sources of information and variation. However, despite the large number of available comparative ontogenetic and eco‐morphological studies on fish, there are still several studies that have so far focussed on the genotype only, in spite of advice for alternative/complementary investigations. This study bridges the knowledge gap resulting from an imbalance between studies rooted on gradual development and genetics and those based on comparative ontogeny and focussed on eco‐morphology and developmental plasticity. As a case study using literature data, a new perspective is proposed on the early ontogeny of some species in the genus Hypseleotris in the light of the concept of alternative ontogenies and developmental plasticity. Based on this framework, an alternative explanation is proposed for the co‐occurrence of empire gudgeon (H. compressa) and firetailed gudgeon (H. galii) in similar habitats, and for the possible existence of intraspecific twin forms within western carp gudgeon (H. klunzingeri) and of interspecific species pairs in the ‘problematic’ carp gudgeon complex (Hypseleotris spp.). Central to this paper is the model of alternative ontogenies (as opposed to the historical, descriptive approach based on ‘normal stages’ of development) and its scientific potential to provide a new reference framework for existing genetic and phylogenetic studies on problematic fish species complexes, for which only genetic studies are currently available.

“…Thus, the role of changing morphology in inducing ontogenetic niche shifts is not always clear (Galis, 1990;Pinder et al, 2005). In this ecomorphological framework, there are three main concerns: (1) the search for a covariation pattern between environmental factors and form, and if found (2) the analysis of this pattern in terms of the functional role and of the performance effects of each morphoanatomical change and (3) the linkage of ecomorphological findings to those of other comparative fields such as ecophysiology, behavioural ecology and evolutionary ecology (Motta & Kotrschal, 1992;Motta et al, 1995a,b;Norton et al, 1995;Smirnov et al, 1995;Xie et al, 2001;Linde et al, 2004;Costa & Cataudella, 2007).…”

The shape development through ontogeny of the gilthead sea bream Sparus aurata was studied by means of geometric morphometry and elliptic Fourier analysis. In parallel, observations are reported on the feeding habits of the same specimens until the end of the larval stage. Data for later stages were obtained from the literature. Sparus aurata underwent ontogenetic shifts in diet from zooplankton, selected by larvae, to mysids, errant polychaete, amphipods and isopods for juveniles, and finally to hard prey (decapods, gastropods and bivalves) in adults. The aims were: (1) to provide a complete description of shape development, from hatching to the adult stage, (2) to identify distinguishable morphological stages during ontogenesis, (3) to search for correspondence between morphological devel- opment and diet shifts, and (4) to examine the functional effect connecting shape changes to diet shifts and habitat selection. The growth trajectory obtained reflected a saturating curve made up by different sections. Each section corresponded to a developmental shape stage characterized by different allometric trends of different body regions. Indeed, these shape stages matched those based on widespread features of development. Furthermore, the size- defined limits of the shape stages closely match the feeding shifts in the development of dietary behaviour of gilthead sea bream. The different constraints underpinning this pattern of covariation are discussed by showing that the growth profile of early stages is mainly determined by organogenesis of important apparati, whereas that of later stages seems optimized to improve feeding on hard prey in complex microhabitat and swimming abilities, and to reduce predation risk
