Cones and consequences: the false dichotomy of conifers vs broad-leaves has critical implications for research and modelling. [PDF]

New Phytol
Summary In plant science research and modelling, particularly from the northern hemisphere, the terms ‘needle‐leaved’ and ‘conifer’ along with ‘broad‐leaved’ and ‘angiosperm’ are often used synonymously, creating the false dichotomy that conifers are needle‐leaved and angiosperms are broad‐leaved.

Substance Use Disorder Treatment Outcomes: Methodological Overview of Metrics and Criteria. [PDF]

Int J Methods Psychiatr Res
ABSTRACT Aim The heterogeneous metrics and criteria used to assess the effectiveness of substance use disorders treatment hinders cross‐study comparisons. This review aims to parse such heterogeneity by analysing the operational definitions of variables used to derive metrics and outcome criteria, contributing to the standardisation process. Methods We

Environmental influence on reproductive traits of buffel grass facultative apomictic genotypes and its implication in plant breeding

Crop Science, Volume 63, Issue 6, Page 3382-3392, November/December 2023., 2023
Abstract Cenchrus ciliaris L., a perennial C4 grass, is one of the most widely used forage species in warm and dry regions worldwide. The widespread use of the cultivar Texas raises concerns about genetic homogeneity and vulnerability. Hybridizations among facultative individuals could widen the genic pool. Therefore, a reproductive characterization of

A theoretical framework for upscaling species distribution models

Methods in Ecology and Evolution, Volume 14, Issue 11, Page 2888-2899, November 2023., 2023
Abstract Species distribution models (SDM) have become one of the most popular predictive tools in ecology. With the advent of new computation and remote sensing technology, high‐resolution environmental data sets are becoming more and more common predictors in these modelling efforts.

Integrating presence‐only and presence–absence data to model changes in species geographic ranges: An example in the Neotropics

Journal of Biogeography, Volume 50, Issue 9, Page 1561-1575, September 2023., 2023
Abstract Aim Anthropogenic changes such as land use and climate change affect species' geographic ranges, causing range shifts, contractions, or expansions. However, data on range dynamics are insufficient, heterogeneous, and spatially and temporally biased in most regions.

Percentile Study of χ Distribution. Application to Response Time Data

Mathematics, 2020
As a continuation of our previous work, where a Maxwell–Boltzmann distribution was found to model a collective’s reaction times, in this work we will carry out a percentile study of the χ distribution for some freedom ranging from k = 2 to k = 10.
