Estimation of species divergence times in presence of cross-species gene flow.
Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when gene flow is ignored in the analysis. Using advances in analytical methods under the multispecies...Tiley, George P ; Flouri, Tomás ; Jiao, Xiyun ; Poelstra, Jelmer W. ; Xu, Bo …

The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation.
Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologies that differ from each other and from the species tree. The effect of these topological incongruences...Carruthers, Tom ; Sun, Miao ; Baker, William J. ; Smith, Stephen A. ; de Vos, Jurriaan M. …

Reconnecting the Cinchona (Rubiaceae) collections of the “Real Expedición Botánica al Virreinato del Perú” (1777-1816).
During the “Real Expedición Botánica al Virreinato del Perú”, 1777-1816, Hipólito Ruiz López (1754-1816), José Antonio Pavón Jiménez (1754-1840), Juan José Tafalla Navascués (1755-1811) and Juan Agustín Manzanilla (fl. 1793-1816) collected economically important specimens of anti-malarial cinchona bark (Cinchona spp.). In the 230 years since, these specimens have been dispersed...Walker, Kim ; García Guillén, Esther ; Allasi Canales, Nataly ; Medina, Leopoldo ; Driver, Felix …

Seasonal dynamics of Anopheles stephensi and its implications for mosquito detection and emergent malaria control in the Horn of Africa.
Invasion of the malaria vector across the Horn of Africa threatens control efforts across the continent, particularly in urban settings where the vector is able to proliferate. Malaria transmission is primarily determined by the abundance of dominant vectors, which often varies seasonally with rainfall. However, it remains unclear how abundance... -

Genetic assimilation of ancestral plasticity during parallel adaptation to zinc contamination in Silene uniflora.
Phenotypic plasticity in ancestral populations is hypothesized to facilitate adaptation, but evidence is piecemeal and often contradictory. Further, whether ancestral plasticity increases the probability of parallel adaptive changes has not been explored. The most general finding is that ancestral responses to a new environment are reversed following adaptation (known as... -

Between Metropole and Province: circulating botany in British museums, 1870–1940.
Exchange of duplicate specimens was an important element of the relationship between metropolitan and regional museums in the period 1870–1940. Evidence of transfers of botanical museum objects such as economic botany specimens is explored for the Royal Botanic Gardens, Kew, and six museums outside the capital: Cambridge University Botanical Museum,... -

Indigenous Peoples’ Food Systems and Biocultural Heritage: Addressing Indigenous Priorities Using Decolonial and Interdisciplinary Research Approaches.
The food systems and territories of Indigenous Peoples sustain much of the world’s biodiversity, cultivated and wild, through agroecological practices rooted in Indigenous cosmovision and cultural and spiritual values. These food systems have a critical role to play in sustainability transformations but are widely threatened and have received limited research...Swiderska, Krystyna ; Argumedo, Alejandro ; Wekesa, Chemuku ; Ndalilo, Leila ; Song, Yiching …

Endophytic fungi related to the ash dieback causal agent encode signatures of pathogenicity on European ash
Tree diseases constitute a significant threat to biodiversity worldwide. Pathogen discovery in natural habitats is of vital importance to understanding current and future threats and prioritising efforts towards developing disease management strategies. Ash dieback is a fungal disease of major conservational concern that is infecting common ash trees, , in...
