Small Sample Inference for Two‐Way Capture‐Recapture Experiments

International Statistical Review, Volume 93, Issue 1, Page 62-72, April 2025.
Summary The properties of the generalised Waring distribution defined on the non‐negative integers are reviewed. Formulas for its moments and its mode are given. A construction as a mixture of negative binomial distributions is also presented. Then we turn to the Petersen model for estimating the population size N in a two‐way capture‐recapture ...

Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?

Journal of Financial Research, EarlyView.
Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...

Neurogenomic landscape associated with status‐dependent cooperative behaviour

Molecular Ecology, EarlyView.
Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.

The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

Molecular Ecology, EarlyView.
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...

Genetic Architecture of Immune Cell DNA Methylation in the Rhesus Macaque

Molecular Ecology, EarlyView.
ABSTRACT Genetic variation that impacts gene regulation, rather than protein function, can have strong effects on trait variation both within and between species. Epigenetic mechanisms, such as DNA methylation, are often an important intermediate link between genotype and phenotype, yet genetic effects on DNA methylation remain understudied in natural ...

Central and noncentral moments of the multivariate hypergeometric distribution [PDF]

arXiv
In this short note, explicit formulas are developed for the central and noncentral moments of the multivariate hypergeometric distribution. A numerical implementation is provided in Mathematica for fast evaluations. This work complements the paper by Ouimet (2021), where analogous formulas were derived and implemented in Mathematica for the multinomial

Diet Driven Differences in Host Tolerance Are Linked to Shifts in Global Gene Expression in a Common Avian Host‐Pathogen System

Molecular Ecology, EarlyView.
ABSTRACT Wildlife have become increasingly dependent on anthropogenic resources, altering interactions between individuals and subsequently disease transmission. Further, nutritional quantity and quality impact an individual's ability to mitigate damage caused by infectious disease.

Assessing lexical proficiency in Russian as a second language using indices of lexical sophistication, diversity, and fluency

The Modern Language Journal, EarlyView.
Abstract Lexical proficiency in a second language (L2) has long been effectively assessed through the measurement of various lexical indices, or textual characteristics that act as observable indicators of such conceptual categories as lexical richness, diversity, sophistication, and fluency.

Evolutionary‐conserved RLF, a cytochrome b5‐like heme‐binding protein, regulates organ development in Marchantia polymorpha

New Phytologist, EarlyView.
Summary In Arabidopsis thaliana, REDUCED LATERAL ROOT FORMATION (RLF), a cytochrome b5‐like heme‐binding domain (Cytb5‐HBD) protein, is necessary for proper lateral root (LR) formation. Whereas the other Cytb5‐HBD proteins in A. thaliana regulate different metabolic reactions, RLF is unique as it specifically regulates organ development.
