Arfianti, T., and M. Costello. 2020. Global biogeography of marine amphipod crustaceans: latitude, regionalization, and beta diversity. Marine Ecology Progress Series 638: 83–94. https://doi.org/10.3354/meps13272
Studying the biogeography of amphipod crustaceans is of interest because they play an important role at lower trophic levels in ecosystems. Because they lack a planktonic larval stage, it has been hypothesized that marine benthic amphipod crustaceans may have short dispersal distances, high endemici…
Bowser, M., R. Brassfield, A. Dziergowski, T. Eskelin, J. Hester, D. Magness, M. McInnis, et al. 2020. Towards conserving natural diversity: A biotic inventory by observations, specimens, DNA barcoding and high-throughput sequencing methods. Biodiversity Data Journal 8. https://doi.org/10.3897/bdj.8.e50124
The Kenai National Wildlife Refuge has been given a broad conservation mandate to conserve natural diversity. A prerequisite for fulfilling this purpose is to be able to identify the species and communities that make up that biodiversity. We tested a set of varied methods for inventory and…

Outbreaks of conifer bark beetles in Europe and North America have increased in scale and severity in recent decades. In this study, we identify existing fossil records containing bark beetle remains from the end of the Last Glacial Maximum (~14,000 cal. yr BP) to present day using the online databa…
Ezray, B. D., D. C. Wham, C. E. Hill, and H. M. Hines. 2019. Unsupervised machine learning reveals mimicry complexes in bumblebees occur along a perceptual continuum. Proceedings of the Royal Society B: Biological Sciences 286: 20191501. https://doi.org/10.1098/rspb.2019.1501
Müllerian mimicry theory states that frequency-dependent selection should favour geographical convergence of harmful species onto a shared colour pattern. As such, mimetic patterns are commonly circumscribed into discrete mimicry complexes, each containing a predominant phenotype. Outside a few exam…
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…
Golnar, A. J., E. Martin, J. D. Wormington, R. C. Kading, P. D. Teel, S. A. Hamer, and G. L. Hamer. 2019. Reviewing the Potential Vectors and Hosts of African Swine Fever Virus Transmission in the United States. Vector-Borne and Zoonotic Diseases 19: 512–524. https://doi.org/10.1089/vbz.2018.2387
African swine fever virus (ASFV) continues to threaten global animal health and agricultural biosecurity. Mitigating the establishment of ASFV in the United States (U.S.) is contingent on (1) the identification of arthropod vectors and vertebrate hosts that are capable of viral maintenance and trans…

The field of quantitative palaeoclimatology has made significant progress in the past decades. However, this progress has been spatially heterogeneous and strong discrepancies – both in terms of quality and density – exist between Europe and North America and the rest of the world. The need to balan…

China’s Belt and Road Initiative (BRI) is an unprecedented global development program that involves nearly half of the world’s countries [1]. It not only will have economic and political influences, but also may generate multiple environmental challenges and is a focus of considerable academic and p…

Earthworms in the family Lumbricidae in Alaska, which are known from coastal regions, primarily in south-central and south-eastern Alaska, are thought to be entirely non-native and have been shown to negatively impact previously earthworm-free ecosystems in study regions outside of Alaska. Despite o…
Piel, W. H. 2018. The global latitudinal diversity gradient pattern in spiders. Journal of Biogeography 45: 1896–1904. https://doi.org/10.1111/jbi.13387
Aim: The aim of this study was to test the hypothesis that the global latitudinal diversity gradient pattern in spiders is pear‐shaped, with maximum species diversity shifted south of the Equator, rather than egg‐shaped, centred on the equator, this study infers the gradient using two large datasets…
