The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Nonparametric estimation of mean and dispersion functions in extended generalized linear models. [PDF]

open access: yes
In this paper the interest is in regression analysis for data that show possibly overdispersion or underdispersion. The starting point for modeling are generalized linear models in which we no longer admit a linear form for the mean regression function ...

Exploring eco‐evolutionary and temporal patterns of arbuscular mycorrhizal fungal communities colonizing Sorghum bicolor across sites of contrasting land use history and climate

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Sorghum bicolor is a globally important cereal crop with annual yields exceeding 50 million tons across more than 100 countries and can be grown on marginal lands where conventional agriculture is limited. We examined how eight genetically diverse sorghum genotypes shaped arbuscular mycorrhizal fungal (AMF) community assembly across two contrasting ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

The Severe Stunting Cases of Children in Central Java Province Explained by Negative Binomial Regression Model

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika)
Severe stunting, or very short stature among children, remains a critical public health concern in Central Java Province. Robust statistical modelling is essential to identify the key factors associated with these cases and to guide targeted ...

How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Mortality in an invasive ant does not scale linearly with fipronil exposure

open access: yesPest Management Science, EarlyView.
Increasing fipronil concentration did not linearly increase yellow crazy ant mortality when introduced via horizontal transfer; high doses may limit food sharing. Queen mortality was low, and surviving workers were averse to feeding. Abstract Background Controlling eusocial invasive and other pestiferous insects is difficult.
