Data from: Can body mass and skull morphology predict seed and fruit ingestion potential for mammal species? A test using extant species and its application to extinct species
<p>Larger animals are assumed to ingest larger seeds and consume larger fruits, but empirical studies reveal inconsistent trends between body mass and the average size of fruits and seeds ingested. Further, no studies have explored seed size relationships with morphological traits, such as skull dimensions. Such characteristics might provide more reliable estimates of ingestion ability and allow for accurate predictions of seed dispersal capacity in species for which we lack empirical data, especially extinct species. To determine whether (i) mammalian skull dimensions are better predictors of the maximum size of ingested seeds and fruits, compared to body mass and (ii) body mass are the better predictors of mean fruit and seed sizes, we studied these relationships across three mammalian orders: Chiroptera, Primates, and Carnivora.</p> <p>We collected novel data on skull dimensions and collated available data on body mass and maximum and mean sizes of ingested fruits and seeds for mammals (N=100) across the Neotropics, Asia, Africa, and Madagascar. We explored the relationships between anatomical traits and fruit and seed sizes of extant species and made predictions for five extinct species.</p> <p>Our results revealed that body mass and skull dimensions are essential determinants of ingested fruit and seed size in mammals. The latter traits can generate predictions for extinct species, especially coronoid height and maximum jaw gape. Nevertheless, body mass predicted larger ingested fruits and seeds than skull dimensions and explained a greater part of the variance for both maximum and mean sizes in our dataset.</p> <p>Our results show how body mass and cranial anatomy constrain seed size and reinforce the importance of maintaining functional diversity in seed dispersers to maintain tropical forest structure. We also show that scientists can use morphological characteristics to predict the seed dispersal potential of extinct mammals allowing better inferences on past and future consequences of frugivore extinctions within tropical forests.</p>
Dataset for: The biogeography of extant lungfishes traces the breakup of Gondwana
<p>Aim: Lungfishes are one of the two surviving clades from the once diverse grade of lobe-finned fishes leading to tetrapods. This classic living fossil lineage, which is the living sister to four-limbed terrestrial vertebrates, appeared approximately 425 million years ago and rapidly diversified. However, the evolution of lungfishes after their initial radiation is poorly understood, and whether their present distribution tracks ancient geographic change is a classic problem in biogeography.</p> <p>Location: Global</p> <p>Taxon: Lungfishes (Dipnoi)</p> <p>Methods: Here, we combine mitogenomic, nuclear gene, and fossil data to reconstruct the timing of lungfish diversification, and integrate fossil species in a Bayesian tip-dating approach to quantitatively test hypotheses of lungfish historical biogeography and divergence times. We sample all major living and extinct lungfish lineages, including three of the four species of African lungfishes (<em>Protopterus</em> spp.), the Australian lungfish <em>Neoceratodus forsteri</em>, the South American lungfish <em>Lepidosiren paradoxa</em>, and 13 fossils representing extinct lineages from across the globe.</p> <p>Results: Our results demonstrate that the divergences of the three major living lungfish clades closely recapitulate the stepwise fragmentation of the Gondwana during the Mesozoic. All of our model-based biogeographic reconstructions support a Gondwanan vicariance model for the origins of the present distribution of lungfish lineages.</p> <p>Conclusions: In turn, lungfishes provide an excellent example of how the integration of fossil data may drastically change support for historical biogeographic hypotheses previously discounted by molecular data and are one of the few living animal lineages that record incredibly ancient geographic changes in their phylogeny.</p>
