Data from: A quantitative method for inferring locomotory shifts in amniotes during ontogeny, its application to dinosaurs, and its bearing on the evolution of posture

Kimberley E. J. Chapelle, Roger B. J. Benson, Josef Stiegler, Alejandro Otero, Qi Zhao & Jonah N. Choiniere
Evolutionary transitions between quadrupedal and bipedal postures are pivotal to the diversification of amniotes on land, including in our own lineage (Hominini). Heterochrony is suggested as a macroevolutionary mechanism for postural transitions, but understanding postural evolution in deep time is hindered by a lack of methods for inferring posture in extinct species. Dinosaurs are an excellent natural laboratory for understanding postural transitions, because their lineage contains at least four instances of quadrupedality evolving from bipedality,...

Data from: A split sex ratio in solitary and social nests of a facultatively social bee

Adam R. Smith, Karen M. Kapheim, Callum J. Kingwell & William T. Wcislo
A classic prediction of kin selection theory is that a mixed population of social and solitary nests of haplodiploid insects should exhibit a split sex ratio among offspring: female biased in social nests, male biased in solitary nests. Here we provide the first evidence of a solitary-social split sex ratio, using the sweat bee Megalopta genalis (Halictidae). Data from 2502 offspring collected from naturally occurring nests across six years spanning the range of the M....

Data from: Games academics play and their consequences: how authorship, h-index, and journal impact factors are shaping the future of academia

Jan Gogarten, Colin Chapman, Julio Bicca-Marques, Sébastien Calvignac-Spencer, Pengfei Fan, Peter Fashing, Songtao Guo, Claire Hemingway, Fabian Leendertz, Baoguo Li, Ikki Matsuda, Rong Hou, Juan Carlos Serio-Silva & Nils Chr. Stenseth
Research is a highly competitive profession where evaluation plays a central role; journals are ranked and individuals are evaluated based on their publication number, the number of times they are cited, and their h-index. Yet, such evaluations are often done in inappropriate ways that are damaging to individual careers, particularly for young scholars, and to the profession. Furthermore, as with all indices, people can play games to better their scores. This has resulted in the...

Data from: A new ancient lineage of frog (Anura: Nyctibatrachidae: Astrobatrachinae subfam. nov.) endemic to the Western Ghats of Peninsular India

The Western Ghats (WG) is an escarpment on the west coast of Peninsular India, housing one of the richest assemblages of frogs in the world, with three endemic families. Here, we report the discovery of a new ancient lineage from a high-elevation massif in the Wayanad Plateau of the southern WG. Phylogenetic analysis reveals that the lineage belongs to Natatanura and clusters with Nyctibatrachidae, a family endemic to the WG/Sri Lanka biodiversity hotspot. Based on...

Data from: Species sorting and mass effect along forest succession: evidence from taxonomic, functional, and phylogenetic diversity of amphibian communities

Omar Hernández-Ordóñez, Braulio A. Santos, Robert Alexander Pyron, Victor Arroyo-Rodriguez, J. Nicolás Urbina-Cardona, Miguel Martínez-Ramos, Gabriela Parra-Olea & Victor Hugo Reynoso
Species recovery after forest disturbance is a highly studied topic in the tropics, but considerable debate remains on the role of secondary forests as biodiversity repositories, especially regarding the functional and phylogenetic dimensions of biodiversity. Also, studies generally overlook how alpha and beta diversities interact to produce gamma diversity along successional gradients. We used a metacommunity approach to assess how species sorting (i.e., environmental filtering) and mass effect (i.e., source‐sink dynamics) affect 14 complementary metrics...

Data from: A phylogenomic framework, evolutionary timeline and genomic resources for comparative studies of decapod crustaceans

Joanna M. Wolfe, Jesse W. Breinholt, Keith A. Crandall, Alan R. Lemmon, Emily Moriarty Lemmon, Laura E. Timm, Mark E. Siddall & Heather D. Bracken-Grissom
Comprising over 15 000 living species, decapods (crabs, shrimp and lobsters) are the most instantly recognizable crustaceans, representing a considerable global food source. Although decapod systematics have received much study, limitations of morphological and Sanger sequence data have yet to produce a consensus for higher-level relationships. Here, we introduce a new anchored hybrid enrichment kit for decapod phylogenetics designed from genomic and transcriptomic sequences that we used to capture new high-throughput sequence data from 94...

Data from: Knowing when to stick: touch receptors found in the remora adhesive disc

Karly E. Cohen, Brooke E. Flammang, Callie H. Crawford & L. Patricia Hernandez
Remoras are fishes that piggyback onto larger marine fauna via an adhesive disc to increase locomotor efficiency, likelihood of finding mates, and access to prey. Attaching rapidly to a large, fast moving host is no easy task, and while research to date has focused on how the disc supports adhesion, no attention has been paid to how or if remoras are able to sense attachment. We identified push-rod-like mechanoreceptor complexes embedded in the soft lip...

A novel role for Eip74EF in male reproduction in promoting sperm elongation at the cost of fecundity

Mollie Manier, Sharif Chebbo, Sarah Josway & John Belote
Spermatozoa are the most morphologically variable cell type, yet little is known about genes controlling natural variation in sperm shape. Drosophila fruit flies have evolved the longest sperm known, which are evolving under postcopulatory sexual selection, driven by sperm competition and cryptic female choice. Long sperm outcompete short sperm but primarily when females have long seminal receptacles (SRs), the primary sperm storage organ. Thus, selection on sperm length is mediated by SR length, and the...
