ABSTRACT Colonization of a novel habitat is often followed by radiation in the wake ecological opportunity. Alternatively, some habitats should be inherently more constraining than others if challenges that environment have few evolutionary solutions. We examined push-and-pull these factors on evolution following transitions, using anglerfishes (Lophiiformes) as model. Deep-sea fishes are notoriously difficult to study, and poor sampling has limited progress thus far. Here we present new phylogeny with unprecedented taxonomic (1,092 loci 40% species), combined three-dimensional phenotypic data from museum specimens obtained micro-CT scanning. use datasets examine tempo mode lineage diversification phylogenetic comparative methods, comparing lineages shallow deep benthic versus bathypelagic habitats.

Synopsis Constraints on phenotypic evolution can lead to patterns of convergent evolution, by limiting the “pool” potential phenotypes in face endogenous (functional, developmental) or exogenous (competition, predation) selective pressures. Evaluation convergence depends integrating ecological and morphological data within a robust, comparative phylogenetic context. The staggering diversity teleost fishes offers multitude lineages adapted for similar roles and, therefore, numerous replicated evolutionary experiments exploring convergence. However, our understanding fish feeding systems has been primarily shaped marine species, with monolithic exception freshwater cichlids. Here we use piranhas pacus (Serrasalmidae) explore different ecologies their proxies Neotropical environments. Specifically, whether is more widespread among plant-eating fishes, arising from strong constraints herbivores. Using osteological micro-computed tomographic imaging (μCT), describe major axes variation piranhas, regarding diet behaviors. Next, evaluated herbivorous niches are less labile than other dietary guilds species’ evolve at slower rate taxa. We then assess how taxa are, using three suites characters (dental, jaw, abdominal morphometrics). Ecologically, herbivory not dead end, exhibiting observed transition rates as those between carnivores omnivores. documented herbivores that have carnivores. Most instances found taxa, specifically frugivores folivores. Moreover, “complete” convergence, indicated positive metrics one morphometric dataset, were only Herbivores do appear under constrained circumstances, but this limited ability.

Diet has been identified as a major driver of reef fish lineage diversification, producing one the most speciose vertebrate assemblages today. Yet, there is minimal understanding how, when and why diet itself evolved. To address this, we used comprehensive gut content dataset, alongside recently developed phylogenetic comparative method to assess multivariate prey use across diverse animal assemblage, coral fishes. Specifically, investigated transitions conservatism diets through evolutionary time. We found two pulses diversification: at end-Cretaceous during Eocene, suggesting that Cretaceous–Palaeogene mass extinction probably provided initial ecological landscape for diversify. The birth modern families Eocene then foundation second wave dietary expansion. Together, our findings showcase role rebound events in shaping diversity fishes on present-day reefs.

During ontogeny, animals often undergo significant shape and size changes, coinciding with ecological shifts. This is evident in parrotfishes (Eupercaria: Labridae), which experience notable shifts during development, transitioning from carnivorous diets as larvae juveniles to herbivorous omnivorous adults, using robust beaks skulls for feeding on coral skeletons other hard substrates. These ontogenetic mirror their evolutionary history, are known have evolved wrasse ancestors. Parallel at phylogenetic levels may resulted similar allometric trajectories within parrotfishes. To test this hypothesis, micro-computed tomography (μCT) scanning three-dimensional geometric morphometrics, we analyse the effects of skull striped parrotfish Scarus iseri compare its allometry allometries 57 162 non-parrotfish wrasses. The young S. shapes resembling wrasses grow towards typical adult forms they mature. There was a relationship between strong evidence parallel slopes Our findings suggest that morphological changes associated shift characterizing interspecific evolution conserved intraspecific ontogenies.

AbstractA clear longitudinal gradient in species richness across oceans is observed extant marine fishes, with the Indo-Pacific exhibiting greatest diversity. Three non-mutually-exclusive evolutionary hypotheses have been proposed to explain this diversity gradient: time for speciation, center of accumulation, and situ diversification rates. Using morphologically disparate syngnatharians (seahorses, dragonets, goatfishes, relatives) as a study system, we tested these additionally assessed whether patterns morphological are congruent patterns. We used well-sampled phylogenies suite phylogenetic comparative methods (including novel phylogenetically corrected Kruskal-Wallis test) that account various sources uncertainty estimate rates lineage disparity within all three major oceanic realms (Indo-Pacific, Atlantic, eastern Pacific), well region. find similar regions, indicating increased syngnatharian due earlier colonizations from Tethys Sea followed by speciation more frequent during Miocene coinciding formation coral reefs. These results support both accumulation hypotheses. Unlike unevenness, shape because early origin body plans their subsequent spread via colonization rather than evolution.

Abstract Adaptive radiations are striking examples of rapid speciation along ecological lines. In adaptive radiations, fast rates lineage diversification often pair with morphological diversification. Such has been documented through the lens drivers, overlooking intrinsic structural constraints that may also have a key role in configuring patterns trait Covariation within and between traits hypothesized to govern axes evolution, either by increasing degree covariation (i.e. integration), which promotes coordination, or strengthening modularity), allows organisms explore novel combinations different regions morphospace. Here, we study modularity skull an radiation pupfishes is endemic San Salvador Island, Bahamas. This exhibits divergent craniofacial morphologies, including generalist, snail-eating specialist, scale-eating specialist species. We assessed disparity, integration strength, across sympatric Island pupfish radiation, lab-reared hybrids, closely related outgroup Our findings revealed unexpected uniformity pattern diverse species, supporting five-module functional hypothesis comprising oral jaw, pharyngeal neurocranium, hyoid apparatus, hyomandibula. Despite this conserved pattern, all species exhibited weak but significantly varying strengths overall between-module significant disparity cranial regions. results suggest can occur even modularity. propose broadscale more while associations evolvable
