Ortiz, A. M. D., and J. N. V. Torres. 2020. Assessing the Impacts of Agriculture and Its Trade on Philippine Biodiversity. Land 9: 403. https://doi.org/10.3390/land9110403
Many Philippine species are at risk of extinction because of habitat loss and degradation driven by agricultural land use and land-use change. The Philippines is one of the world’s primary banana and pineapple producers. The input-intensive style of plantation agriculture for these typically exporte…
Fletcher, T. L., A. Z. Csank, and A. P. Ballantyne. 2019. Identifying bias in cold season temperature reconstructions by beetle mutual climatic range methods in the Pliocene Canadian High Arctic. Palaeogeography, Palaeoclimatology, Palaeoecology 514: 672–676. https://doi.org/10.1016/j.palaeo.2018.11.025
Well-preserved beetle elytra from the fossil and subfossil record are used by palaeoclimatologists to estimate past temperatures. Beetle-derived estimates of temperature across the Pliocene Arctic are consistently lower than those derived from other palaeoclimate proxies. Here we test if that patter…
Li, X., B. Li, G. Wang, X. Zhan, and M. Holyoak. 2020. Deeply digging the interaction effect in multiple linear regressions using a fractional-power interaction term. MethodsX 7: 101067. https://doi.org/10.1016/j.mex.2020.101067
In multiple regression Y ~ β0 + β1X1 + β2X2 + β3X1 X2 + ɛ., the interaction term is quantified as the product of X1 and X2. We developed fractional-power interaction regression (FPIR), using βX1M X2N as the interaction term. The rationale of FPIR is that the slopes of Y-X1 regression along the X2 gr…

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…
Ahn, K.-J., D. S. Sikes, and J. Klimaszewski. 2020. Paramblopusa eoa Ahn and Maruyama (Coleoptera: Staphylinidae: Aleocharinae), Distributional Range Extension to Alaska. The Coleopterists Bulletin 74: 324. https://doi.org/10.1649/0010-065x-74.2.324
The intertidal staphylinid genus Paramblopusa Ahn and Ashe, which contains two species, Paramblopusa borealis (Casey) and Paramblopusa eoa Ahn and Maruyama, occurs along the northern Pacific coast, from Oregon through Alaska to the Kuril Islands. These species live under rocks and pebbles in the mid…

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., M. Niemiller, C. Stephen, B. Ayala, M. Milne, N. Gladstone, A. Engel, et al. 2020. Biodiversity from caves and other sub-terranean habitats of Georgia, USA. Journal of Cave and Karst Studies 82: 125–167. 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…

Citizen science (CS) contributes to the knowledge about species distributions, which is a critical foundation in the studies of invasive species, biological conservation, and response to climatic change. In this study, we assessed the value of CS for termites worldwide. First, we compared the abunda…
Nicolai, A., and R. G. Forsyth. 2020. Introduced Prophysaon andersonii (J.G. Cooper, 1872) in Quebec, Canada: first record of Prophysaon (Gastropoda, Eupulmonata, Arionoidea) in eastern North America, confirmed by partial-COI gene sequence. Check List 16: 307–316. https://doi.org/10.15560/16.2.307
We report for the first time the terrestrial slug Prophysaon andersonii (J.G. Cooper, 1872) from Quebec, Canada. Two specimens were collected in Parc national du Bic. The identification was determined by the external morphology and partial-COI gene sequence data. The genus Prophysaon is endemic to w…

Marine environments have increased in temperature by an average of 1°C since pre-industrial (1850) times [1]. Given that species ranges are closely allied to physiological thermal tolerances in marine organisms [2], it may therefore be expected that ocean warming would lead to abundance increases at…
