Biological traits, geographic distributions, and species conservation in aquatic ecosystems

Diversity and Distributions: A journal of biological invasions and biodiversity, 2022
Aquatic ecosystems (both marine and freshwater) have long served as model systems for exploring the role of environmental stressors on organismal performance and survival, the biogeographic distributions of populations and species, and ultimately the ...

Rare Event Classification with Weighted Logistic Regression for Identifying Repeating Fast Radio Bursts

The Astrophysical Journal
An important task in the study of fast radio bursts (FRBs) remains the automatic classification of repeating and nonrepeating sources based on their morphological properties. We propose a statistical model that considers a modified logistic regression to

Distributions of Wide Binary Stars in Theory and in Gaia Data. II. Reconstruction of Sample Probability Density of True Orbit Sizes

The Astronomical Journal
Wide binary stars are important for testing alternative models of gravitation in the weak-field regime and understanding the statistical outcomes of dynamical interactions in the general Galactic field. The Gaia mission’s collection of weakly bound pairs

A Bias-corrected Luminosity Function for Red Supergiant Supernova Progenitor Stars

The Astrophysical Journal Letters
The apparent tension between the luminosity functions of red supergiant (RSG) stars and of RSG progenitors of Type II supernovae (SNe) is often referred to as the RSG problem and it motivated some to suggest that many RSGs end their life without an SN ...

Combined effects of climate and fire‐driven vegetation change constrain the distributions of forest vertebrates during the 21st century

Diversity and Distributions: A journal of biological invasions and biodiversity, 2022
Biodiversity conservation relies in part on enduring habitat in protected areas. In fire‐prone ecosystems, shifts in species’ ranges will result both from changes in climate and fire‐catalysed vegetation change, which could lead to niche contraction and ...

Trait‐based projections of climate change effects on global biome distributions

Diversity and Distributions: A journal of biological invasions and biodiversity, 2021
Climate change will likely modify the global distribution of biomes, but the magnitude of change is debated. Here, we followed a trait‐based, statistical approach to model the influence of climate change on the global distribution of biomes.

Distributions of Wide Binary Stars in Theory and in Gaia Data. I. Generalized Ambartsumian (1937) Approach and the Family of Power-law Distributions of Eccentricity

The Astronomical Journal
The orbital parameter space of wide, weakly bound binary stars has been shaped by the still poorly known circumstances of their formation, as well as by subsequent dynamical evolution in parent clusters and in the field.

Climatic predictors of species distributions neglect biophysiologically meaningful variables

Diversity and Distributions: A journal of biological invasions and biodiversity, 2019
Species distribution models (SDMs) have played a pivotal role in predicting how species might respond to climate change. To generate reliable and realistic predictions from these models requires the use of climate variables that adequately capture ...
