Cours, J., Larrieu, L., Lopez-Vaamonde, C., Müller, J., Parmain, G., Thorn, S., & Bouget, C. (2021). Contrasting responses of habitat conditions and insect biodiversity to pest- or climate-induced dieback in coniferous mountain forests. Forest Ecology and Management, 482, 118811. doi:10.1016/j.foreco.2020.118811 https://doi.org/10.1016/j.foreco.2020.118811

Natural disturbances are major drivers of forest dynamics. However, in the current context of anthropogenic global warming, shifts in disturbance regimes are expected. Natural disturbances usually leave biological or structural legacies which are important for early-successional species. Nevertheles…

Brendel, M. R., Schurr, F. M., & Sheppard, C. S. (2020). Inter‐ and intraspecific selection in alien plants: How population growth, functional traits and climate responses change with residence time. Global Ecology and Biogeography. doi:10.1111/geb.13228 https://doi.org/10.1111/geb.13228

Aim: When alien species are introduced to new ranges, climate or trait mismatches may initially constrain their population growth. However, inter‐ and intraspecific selection in the new environment should cause population growth rates to increase with residence time. Using a species‐for‐time approac…

Deanna, R., Wilf, P., & Gandolfo, M. A. (2020). New physaloid fruit‐fossil species from early Eocene South America. American Journal of Botany, 107(12), 1749–1762. doi:10.1002/ajb2.1565 https://doi.org/10.1002/ajb2.1565

Premise: Solanaceae is a scientifically and economically important angiosperm family with a minimal fossil record and an intriguing early evolutionary history. Here, we report a newly discovered fossil lantern fruit with a suite of features characteristic of Physalideae within Solanaceae. The fossil…

Quiroga, R. E., Premoli, A. C., & Fernández, R. J. (2020). Niche dynamics in amphitropical desert disjunct plants: Seeking for ecological and species‐specific influences. Global Ecology and Biogeography. doi:10.1111/geb.13215 https://doi.org/10.1111/geb.13215

Aim: Numerous studies have assessed whether species niches are conserved in geographically separated regions. However, most of them were performed on invasive species, with the limitation that such species have likely not yet reached their potential distribution in the invaded region. Here we test t…

Afonin, A. N., Baranova, O. G., & Fedorova, Y. A. (2020). Northern border of Ambrosia artemisiifolia L. distribution in Canada in relation to the establishing of its environmental limits. Vestnik Tomskogo Gosudarstvennogo Universiteta. Biologiya, (50), 28–51. doi:10.17223/19988591/50/2 https://doi.org/10.17223/19988591/50/2

Проведен эколого-географический анализ встречаемости амброзии полыннолистной (Ambrosia artemisiifolia L.) на северном пределе ее распространения в Канаде. В качестве ведущего фактора, лимитирующего распространение вида на север, выступает недостаточная теплообеспеченность периода созревания семян. С…

Larridon, I., Galán Díaz, J., Bauters, K., & Escudero, M. (2020). What drives diversification in a pantropical plant lineage with extraordinary capacity for long‐distance dispersal and colonization? Journal of Biogeography. doi:10.1111/jbi.13982 https://doi.org/10.1111/jbi.13982

Aim: Colonization of new areas may entail shifts in diversification rates linked to biogeographical movement (dispersification), which may involve niche evolution if species were not exapted to new environments. Scleria (Cyperaceae) includes c. 250 species and has a pantropical distribution suggesti…

Lake, T. A., Briscoe Runquist, R. D., & Moeller, D. A. (2020). Predicting range expansion of invasive species: Pitfalls and best practices for obtaining biologically realistic projections. Diversity and Distributions, 26(12), 1767–1779. doi:10.1111/ddi.13161 https://doi.org/10.1111/ddi.13161

Aim: Species distribution models (SDMs) are widely used to forecast potential range expansion of invasive species. However, invasive species occurrence datasets often have spatial biases that may violate key SDM assumptions. In this study, we examined alternative methods of spatial bias correction a…

Zizka, A., Antunes Carvalho, F., Calvente, A., Rocio Baez-Lizarazo, M., Cabral, A., Coelho, J. F. R., … Antonelli, A. (2020). No one-size-fits-all solution to clean GBIF. PeerJ, 8, e9916. doi:10.7717/peerj.9916 https://doi.org/10.7717/peerj.9916

Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given the rapid increase in availability of such data, th…

Mapaura, A., Canavan, K., Richardson, D. M., Clark, V. R., & Steenhuisen, S.-L. (2020). The invasive grass genus Nassella in South Africa: A synthesis. South African Journal of Botany, 135, 336–348. doi:10.1016/j.sajb.2020.08.031 https://doi.org/10.1016/j.sajb.2020.08.031

Three species of Nassella have naturalized in South Africa. Nassella trichotoma and N. tenuissima are declared weeds under category 1b of the National Environmental Management: Biodiversity Act (NEM:BA) and occur mainly in the montane grasslands of the Western and Eastern Cape provinces. Nassella ne…
