Medina, A. M., & Almeida-Neto, M. (2020). Grinnelian and Eltonian niche conservatism of the European honeybee (Apis mellifera) in its exotic distribution. Sociobiology, 67(2), 239. doi:10.13102/sociobiology.v67i2.4901 https://doi.org/10.13102/sociobiology.v67i2.4901

The understanding of how niche-related traits change during species invasion have prompted what is now known as the niche conservatism principle. Most studies that have tested the niche conservatism principle have focused on the extent to which the species’ climatic niches remain stable in their exo…

Liu, X., Blackburn, T. M., Song, T., Wang, X., Huang, C., & Li, Y. (2020). Animal invaders threaten protected areas worldwide. Nature Communications, 11(1). doi:10.1038/s41467-020-16719-2 https://doi.org/10.1038/s41467-020-16719-2

Protected areas are the cornerstone of biodiversity conservation. However, alien species invasion is an increasing threat to biodiversity, and the extent to which protected areas worldwide are resistant to incursions of alien species remains poorly understood. Here, we investigate establishment by 8…

Zigler, K., Niemiller, M., Stephen, C., Ayala, B., Milne, M., Gladstone, N., … Cressler, A. (2020). Biodiversity from caves and other sub-terranean habitats of Georgia, USA. Journal of Cave and Karst Studies, 82(2), 125–167. doi:10.4311/2019lsc0125 https://doi.org/10.4311/2019LSC0125

We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemi…

Escalante, T., Varela-Anaya, A. M., Noguera-Urbano, E. A., Elguea-Manrique, L. M., Ochoa-Ochoa, L. M., Gutiérrez-Velázquez, A. L., … Rodríguez-Soto, C. (2020). Evaluation of five taxa as surrogates for conservation prioritization in the Transmexican Volcanic Belt, Mexico. Journal for Nature Conservation, 125800. doi:10.1016/j.jnc.2020.125800 https://doi.org/10.1016/j.jnc.2020.125800

Many biotic groups have been proposed as biodiversity surrogates; however, using different taxa could provide complementary information for choosing conservation priorities. There are two general ways to evaluate the performance of surrogates: (1) using cross-taxon congruency as an a priori test, be…

Daniel, J., Horrocks, J., & Umphrey, G. J. (2019). Efficient Modelling of Presence-Only Species Data via Local Background Sampling. Journal of Agricultural, Biological and Environmental Statistics. doi:10.1007/s13253-019-00380-4 https://doi.org/10.1007/s13253-019-00380-4

In species distribution modelling, records of species presence are often modelled as a realization of a spatial point process whose intensity is a function of environmental covariates. One way to fit a spatial point process model is to apply logistic regression to an artificial case–control sample c…

Ezray, B. D., Wham, D. C., Hill, C. E., & Hines, H. M. (2019). Unsupervised machine learning reveals mimicry complexes in bumblebees occur along a perceptual continuum. Proceedings of the Royal Society B: Biological Sciences, 286(1910), 20191501. doi:10.1098/rspb.2019.1501 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…
