Lewthwaite, J. M. M., and A. Ø. Mooers. 2021. Geographical homogenization but little net change in the local richness of Canadian butterflies A. Baselga [ed.],. Global Ecology and Biogeography 31: 266–279. https://doi.org/10.1111/geb.13426

Aim: Recent studies have found that local-scale plots measured through time exhibit marked variation in the change in species richness. However, the overall effect often reveals no net change. Most studies to date have been agnostic about the identities of the species lost/gained and about the proce…

Efforts to conserve the migratory phenomenon of monarch butterflies in eastern North America have increased since a 2013–2014 monitoring report documenting a historical population low at the Monarch Butterfly Biosphere Reserve in Mexico. Surprisingly, there have been few systematic attempts to devel…

Scharff, N., J. A. Coddington, T. A. Blackledge, I. Agnarsson, V. W. Framenau, T. Szűts, C. Y. Hayashi, and D. Dimitrov. 2019. Phylogeny of the orb‐weaving spider family Araneidae (Araneae: Araneoidea). Cladistics 36: 1–21. https://doi.org/10.1111/cla.12382

We present a new phylogeny of the spider family Araneidae based on five genes (28S, 18S, COI, H3 and 16S) for 158 taxa, identified and mainly sequenced by us. This includes 25 outgroups and 133 araneid ingroups representing the subfamilies Zygiellinae Simon, 1929, Nephilinae Simon, 1894, and the typ…

Antonelli, A., A. Zizka, F. A. Carvalho, R. Scharn, C. D. Bacon, D. Silvestro, and F. L. Condamine. 2018. Amazonia is the primary source of Neotropical biodiversity. Proceedings of the National Academy of Sciences 115: 6034–6039. https://doi.org/10.1073/pnas.1713819115

The American tropics (the Neotropics) are the most species-rich realm on Earth, and for centuries, scientists have attempted to understand the origins and evolution of their biodiversity. It is now clear that different regions and taxonomic groups have responded differently to geological and climati…
