Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

Ecography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

BINOMIAL COEFFICIENT IDENTITIES AND HYPERGEOMETRIC SERIES

, 2008
In recent months I have come across many instances in which someone has found what they believe is a new result, in which they evaluate in closed form a sum involving binomial coefficients or factorials.

Associations between mycorrhizal dominance and woody species diversity shift with stand development and climate across subtropical and tropical forests in Taiwan

Ecography, EarlyView.
Mycorrhizal symbioses influence woody species diversity, but whether this association shifts with forest stand development remains underexplored. Using forest inventory data across subtropical and tropical forests in Taiwan, we found that woody species diversity was lower in ectomycorrhizal (EM)‐dominated than in arbuscular mycorrhizal (AM)‐dominated ...

On p,q-binomial Coefficients

, 2007
In this paper, we develop the theory of a p, q-analogue of the binomial coefficients. Some properties and identities parallel to those of the usual and q-binomial coefficients will be established including the triangular, vertical, and the horizontal recurrence relations, horizontal generating function, and the orthogonality and inverse relations.

Taxon‐dependent multisite species turnover in fragmented habitats: comparing zeta diversity across birds, butterflies, and cursorial hunting spiders

Ecography, EarlyView.
Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Scale‐dependent assembly shapes taxon‐dependent responses of soil microbes to island isolation and area

Ecography, EarlyView.
The theory of island biogeography (TIB) remains contentious for microbes, as their immense dispersal potential and microscopic size may decouple diversity from classic isolation/area effects. We explicitly tested TIB scaling rules for soil bacteria and fungi across 20 oceanic islands using a rigorous multi‐scale framework that integrated high ...

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

ESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

National Football Teams’ Performance Predicts Spectators’ Identities, Affect and Sociopolitical Attitudes: An Investigation During the 2024 EURO Tournament

European Journal of Social Psychology, EarlyView.
ABSTRACT On the basis of two social‐affective frameworks, we posited that national football team performance (winning vs. losing) would impact spectators’ identities, affect and sociopolitical attitudes—including their intergroup attitudes (i.e., in‐group favouritism and multiculturalism) and societal perceptions (i.e., national optimism, perceived ...

Re‐evaluating impaired consciousness in temporal lobe epilepsy: The role of language dominance and network reorganization

Epilepsia, EarlyView.
Abstract Objective Temporal lobe epilepsy (TLE) frequently affects clinically‐classified ictal consciousness, which the 2025 International League Against Epilepsy (ILAE) classification operationalizes through clinical assessment of awareness and responsiveness.
