Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

open access: yesNordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

open access: yesOikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores

open access: yesOikos, EarlyView.
Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.

Plant and insect functional traits influence herbivore performance under climate change

open access: yesOikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

Nutrient value and in vitro rumen fermentation characteristics of pumpkin vines, sweet potato vines, grape vines and pepper straw for yaks

open access: yesFrontiers in Animal Science
IntroductionReducing feed costs and promoting sustainability are key challenges in yak production. This study aimed to comprehensively evaluate the potential of four locally available agricultural by-products—pumpkin vines (PV), sweet potato vines (SPV),

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

open access: yesOikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.

Connecting tradition and technology: The digitization of the ethnobotanical collection at the Rio de Janeiro Botanical Garden

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The digitization of RBetno (JBRJ) represents a step forward for biodiversity conservation in Brazil. Aligned with the Kunming‐Montreal Global Biodiversity Framework (Target 2, 2020–2030), this project documents the use of plants, including traditional knowledge and vernacular names, with a focus on the Atlantic Forest and Amazon.

Proline-Rich Specific Yeast Derivatives Enhance Grapevine (Vitis vinifera L.) Water Status and Enable Reduced Irrigation Volumes

open access: yesAgronomy
In plants, proline acts as a compatible osmolyte with multiple stress-related functions, contributing to cell turgor regulation and the dissipation of excess energy.
