Grünig, M., Calanca, P., Mazzi, D., & Pellissier, L. (2020). Inflection point in climatic suitability of insect pest species in Europe suggests non‐linear responses to climate change. Global Change Biology. doi:10.1111/gcb.15313 https://doi.org/10.1111/gcb.15313

Climate change and globalization affect the suitable conditions for agricultural crops and insect pests, threatening future food security. It remains unknown whether shifts in species’ climatic suitability will be linear or rather non‐linear, with crop exposure to pests suddenly increasing when a cr…

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…

Guevara, L., & Sánchez-Cordero, V. (2018). New records of a critically endangered shrew from Mexican cloud forests (Soricidae, Cryptotis nelsoni) and prospects for future field research. Biodiversity Data Journal, 6. doi:10.3897/bdj.6.e26667 https://doi.org/10.3897/BDJ.6.e26667

The Nelson´s small-eared shrew, Cryptotisnelsoni (Merriam, 1895), is a critically endangered species, endemic to cloud forests in Los Tuxtlas, a mountain range along the Gulf of Mexico coast. This species is only known from the type locality and its surroundings. Here we present new records that ext…

Koch, J. B., Vandame, R., Mérida-Rivas, J., Sagot, P., & Strange, J. (2018). Quaternary climate instability is correlated with patterns of population genetic variability in Bombus huntii . Ecology and Evolution, 8(16), 7849–7864. doi:10.1002/ece3.4294 https://doi.org/10.1002/ece3.4294

Climate oscillations have left a significant impact on the patterns of genetic diversity observed in numerous taxa. In this study, we examine the effect of Quaternary climate instability on population genetic variability of a bumble bee pollinator species, Bombus huntii in western North America. Ple…
