Disproportionate extinction of South American mammals drove the asymmetry of the Great American Biotic Interchange.
The interchange between the previously disconnected faunas of North and South America was a massive experiment in biological invasion. A major gap in our understanding of this invasion is why there was a drastic increase in the proportion of mammals of North American origin found in South America. Four nonmutually... -

The rise of angiosperms pushed conifers to decline during global cooling
Competition among species and entire clades can impact species diversification and extinction, which can shape macroevolutionary patterns. The fossil record shows successive biotic turnovers such that a dominant group is replaced by another. One striking example involves the decline of gymnosperms and the rapid diversification and ecological dominance of angiosperms...Condamine, Fabien L. ; Silvestro, Daniele ; Koppelhus, Eva B. ; Antonelli, Alexandre

Repeat-sequence turnover shifts fundamentally in species with large genomes.
Given the 2,400-fold range of genome sizes (0.06–148.9 Gbp (gigabase pair)) of seed plants (angiosperms and gymnosperms) with a broadly similar gene content (amounting to approximately 0.03 Gbp), the repeat-sequence content of the genome might be expected to increase with genome size, resulting in the largest genomes consisting almost entirely of repetitive...Novák, Petr ; Guignard, Maïté S. ; Neumann, Pavel ; Kelly, Laura J. ; Mlinarec, Jelena …

Identifying and mapping individual plants in a highly diverse high-elevation ecosystem using UAV imagery and deep learning
The identification and counting of plant individuals is essential for environmental monitoring. UAV based imagery offer ultra-fine spatial resolution and flexibility in data acquisition, and so provide a great opportunity to enhance current plant and in-situ field surveying. However, accurate mapping of individual plants from UAV imagery remains challenging, given...Zhang, Ce ; Atkinson, Peter M. ; George, Charles ; Wen, Zhaofei ; Diazgranados, Mauricio …

Plant Power: Opportunities and challenges for meeting sustainable energy needs from the plant and fungal kingdoms
Societal Impact Statement Bioenergy is a major component of the global transition to renewable energy technologies. The plant and fungal kingdoms offer great potential but remain mostly untapped. Their increased use could contribute to the renewable energy transition and addressing the United Nations Sustainable Development Goal 7 “Ensure access to...Grace, Olwen M. ; Lovett, Jon C. ; Gore, Charles J.

Rapid diversification rates in Amazonian Chrysobalanaceae inferred from plastid genome phylogenetics
We studied the evolutionary history of Chrysobalanaceae with phylogenetic analyses of complete plastid genomes from 156 species to assess the tempo of diversification in the Neotropics and help to unravel the causes of Amazonian plant diversification. These plastid genomes had a mean length of 162 204 base pairs, and the...Chave, Jerome ; Sothers, Cynthia ; Iribar, Amaia ; Suescun, Uxue ; Chase, Mark W …

KEYLINK: towards a more integrative soil representation for inclusion in ecosystem scale models. I. review and model concept
The relatively poor simulation of the below-ground processes is a severe drawback for many ecosystem models, especially when predicting responses to climate change and management. For a meaningful estimation of ecosystem production and the cycling of water, energy, nutrients and carbon, the integration of soil processes and the exchanges at...Deckmyn, Gaby ; Flores, Omar ; Mayer, Mathias ; Domene, Xavier ; Schnepf, Andrea …

Selective extinction against redundant species buffers functional diversity
The extinction of species can destabilize ecological processes. A way to assess the ecological consequences of species loss is by examining changes in functional diversity. The preservation of functional diversity depends on the range of ecological roles performed by species, or functional richness, and the number of species per role,...Pimiento, Catalina ; Bacon, Christine D. ; Silvestro, Daniele ; Hendy, Austin ; Jaramillo, Carlos …

The past and future human impact on mammalian diversity
To understand the current biodiversity crisis, it is crucial to determine how humans have affected biodiversity in the past. However, the extent of human involvement in species extinctions from the Late Pleistocene onward remains contentious. Here, we apply Bayesian models to the fossil record to estimate how mammalian extinction rates...Andermann, Tobias ; Faurby, Søren ; Turvey, Samuel T. ; Antonelli, Alexandre ; Silvestro, Daniele

Are Urban Communities in Successional Stasis? A Case Study on Epiphytic Lichen Communities
Urban areas may contain a wide range of potential habitats and environmental gradients and, given the many benefits to human health and well-being, there is a growing interest in maximizing their biodiversity potential. However, the ecological patterns and processes in urban areas are poorly understood. Using a widely applicable ecological...Llewellyn, Theo ; Gaya, Ester ; Murrell, David J.
