Bioinvasions pose a major threat to global biodiversity. Correlative Ecological Niche Models (ENMs) can be a valuable tool to identify invaders and invasion sites. However, in cases when species are in non-equilibrium with their native environment (i.e. do not fill their niche), correlative approach…
Beaulieu, W. T., D. G. Panaccione, Q. N. Quach, K. L. Smoot, and K. Clay. 2021. Diversification of ergot alkaloids and heritable fungal symbionts in morning glories. Communications Biology 4. https://doi.org/10.1038/s42003-021-02870-z
Heritable microorganisms play critical roles in life cycles of many macro-organisms but their prevalence and functional roles are unknown for most plants. Bioactive ergot alkaloids produced by heritable Periglandula fungi occur in some morning glories (Convolvulaceae), similar to ergot alkaloids in …
Vasconcelos, T., J. D. Boyko, and J. M. Beaulieu. 2021. Linking mode of seed dispersal and climatic niche evolution in flowering plants. Journal of Biogeography. https://doi.org/10.1111/jbi.14292
Aim: Due to the sessile nature of flowering plants, movements to new geographical areas occur mainly during seed dispersal. Frugivores tend to be efficient dispersers because animals move within the boundaries of their preferable niches, so seeds are more likely to be transported to environments tha…
Xue, T., S. R. Gadagkar, T. P. Albright, X. Yang, J. Li, C. Xia, J. Wu, and S. Yu. 2021. Prioritizing conservation of biodiversity in an alpine region: Distribution pattern and conservation status of seed plants in the Qinghai-Tibetan Plateau. Global Ecology and Conservation 32: e01885. https://doi.org/10.1016/j.gecco.2021.e01885
The Qinghai-Tibetan Plateau (QTP) harbors abundant and diverse plant life owing to its high habitat heterogeneity. However, the distribution pattern of biodiversity hotspots and their conservation status remain unclear. Based on 148,283 high-resolution occurrence coordinates of 13,450 seed plants, w…
Arfianti, T., and M. J. Costello. 2021. The distribution of benthic amphipod crustaceans in Indonesian seas. PeerJ 9: e12054. https://doi.org/10.7717/peerj.12054
Amphipod crustaceans are an essential component of tropical marine biodiversity. However, their distribution and biogeography have not been analysed in one of the world’s largest tropical countries nested in the Coral Triangle, Indonesia. We collected and identified amphipod crustaceans from eight s…
Wang, C.-J., and J.-Z. Wan. 2021. Functional trait perspective on suitable habitat distribution of invasive plant species at a global scale. Perspectives in Ecology and Conservation 19: 475–486. https://doi.org/10.1016/j.pecon.2021.07.002
Plant invasion has been proved to threaten biodiversity conservation and ecosystem maintenance at a global scale. It is a challenge to project suitable habitat distributions of invasive plant species (IPS) for invasion risk assessment at large spatial scales. Interaction outcomes between native and …
Majure, L. C., A. Blankenship, A. Grinage, and A. Noa-Monzón. 2021. Castela (Simaroubaceae), an impressive New World radiation of thorny shrubs destined for edaphically dry habitats. Brazilian Journal of Botany 45: 237–249. https://doi.org/10.1007/s40415-021-00742-8
Castela Turpin is composed of 16 known species and is found throughout edaphically dry zones across the American continents from the Sonoran Desert to the southern South American Chaco biogeographic region and Caribbean seasonally dry tropical forests (SDTF). Castela is most diverse in the SDTF of t…
Baumbach, L., D. L. Warren, R. Yousefpour, and M. Hanewinkel. 2021. Climate change may induce connectivity loss and mountaintop extinction in Central American forests. Communications Biology 4. https://doi.org/10.1038/s42003-021-02359-9
The tropical forests of Central America serve a pivotal role as biodiversity hotspots and provide ecosystem services securing human livelihood. However, climate change is expected to affect the species composition of forest ecosystems, lead to forest type transitions and trigger irrecoverable losses…
Dellinger, A. S., R. Pérez‐Barrales, F. A. Michelangeli, D. S. Penneys, D. M. Fernández‐Fernández, and J. Schönenberger. 2021. Low bee visitation rates explain pollinator shifts to vertebrates in tropical mountains. New Phytologist 231: 864–877. https://doi.org/10.1111/nph.17390
Evolutionary shifts from bee to vertebrate pollination are common in tropical mountains. Reduction in bee pollination efficiency under adverse montane weather conditions was proposed to drive these shifts. Although pollinator shifts are central for the evolution and diversification of angiosperms, w…

Natural history specimens are widely used across ecology, evolutionary biology and conservation. Although biological sex may influence all of these areas, it is often overlooked in large-scale studies using museum specimens. If collections are biased towards one sex, studies may not be representativ…
