Converging on the orb: denser taxon sampling elucidates spider phylogeny and new analytical methods support repeated evolution of the orb web

Kallal, Robert J.; Kulkarni, Siddharth S; Dimitrov, Dimitar; Benavides, Ligia R.; Arnedo, Miquel A.; Giribet, Gonzalo; Hormiga, Gustavo (Journal article; Peer reviewed, 2020)

High throughput sequencing and phylogenomic analyses focusing on relationships among spiders have both reinforced and upturned long‐standing hypotheses. Likewise, the evolution of spider webs—perhaps their most emblematic ...
Interrogating genomic-scale data to resolve recalcitrant nodes in the Spider Tree of Life

Kulkarni, Siddharth; Kallal, Robert J.; Wood, Hannah; Dimitrov, Dimitar; Giribet, Gonzalo; Hormiga, Gustavo (Journal article; Peer reviewed, 2020)

Genome-scale data sets are converging on robust, stable phylogenetic hypotheses for many lineages; however, some nodes have shown disagreement across classes of data. We use spiders (Araneae) as a system to identify the ...
Monophyly, Taxon Sampling, and the Nature of Ranks in the Classification of Orb-Weaving Spiders (Araneae: Araneoidea)

Kallal, Robert J.; Dimitrov, Dimitar; Arnedo, Miquel A.; Giribet, Gonzalo; Hormiga, Gustavo (Peer reviewed; Journal article, 2020)

We address some of the taxonomic and classification changes proposed by Kuntner et al. (2019) in a comparative study on the evolution of sexual size dimorphism in nephiline spiders. Their proposal to recircumscribe araneids ...
