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.

Local prior information and mainland overflow explain avian colonisation in a major land‐bridge island

Journal of Biogeography, Volume 50, Issue 9, Page 1615-1622, September 2023., 2023
Abstract Aim The relative roles of intrinsic and extrinsic factors, and those of local and regional variables, in island colonisation, remain major biogeographical questions. Thus, we analysed avian colonisation records of a large land‐bridge island, defining successful colonisation as the occurrence of breeding during at least 3 consecutive years, at ...

A partial least squares analysis of gender inequality, occupational segregation, and economic growth: Evidence from Sub‐Saharan Africa

Regional Science Policy &Practice, Volume 15, Issue 6, Page 1299-1316, August 2023., 2023
Abstract The biggest barrier to an egalitarian Sub‐Saharan Africa (SSA) appears to be deeply ingrained structural obstacles and gender imbalances. The significant prevalence of gender inequities, which have both structural and economic ramifications, must be addressed if SSA is committed to achieving the Africa 2063 Agenda (the Africa we want) and ...

Monte Carlo Simulation of a Modified Chi Distribution with Unequal Variances in the Generating Gaussians. A Discrete Methodology to Study Collective Response Times

Mathematics, 2020
The Chi distribution is a continuous probability distribution of a random variable obtained from the positive square root of the sum of k squared variables, each coming from a standard Normal distribution (mean = 0 and variance = 1).

Exploring young students creativity: The effect of model eliciting activities [PDF]

, 2014
The aim of this paper is to show how engaging students in real-life mathematical situations can stimulate their mathematical creative thinking. We analyzed the mathematical modeling of two girls, aged 10 and 13 years, as they worked on an authentic task ...
