Natural Cross-Pollination in Cotton

open access: yes, 1954
Natural cross-pollination has important implications in cotton breeding and cottonseed production. Control of the genetic complex that determines the potential value of a cotton plant for economic use is important, regardless of the breeding methods employed.

A Chance‐Constrained Model for a Production Routing Problem With Uncertain Availability of Vehicles

open access: yesNetworks, EarlyView.
ABSTRACT The Production Routing Problem (PRP) is a complex integrated problem that allows for the achievement of competitive advantages, such as better management of inventory, reduction in operational costs and lead times, improvement in efficiency and customer service, and better response to market changes.

Petrocosmea wentsaii sp. nov. (Gesneriaceae) from Guizhou, China

open access: yesNordic Journal of Botany, EarlyView.
Petrocosmea wentsaii M.Q. Han, Miao.M. Wang & Yan Liu, a new species from Guizhou, China, is described and illustrated. Petrocosmea wentsaii was found on damp walls in a huge limestone cave. It is most similar to Petrocosmea hexiensis S.Z. Zhang & Z.Y. Liu in the conformation of the corolla.

A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)

open access: yesNordic Journal of Botany, EarlyView.
Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.

Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

open access: yesNordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

open access: yesOikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.
