Zero & N‐Inflated Overdispersed Binomial Models for Sum‐Constrained Poisson Count Processes

open access: yesEnvironmetrics, Volume 37, Issue 7, October 2026.
ABSTRACT Ecological monitoring programmes and palaeoecological analyses play a key role in understanding how biodiversity, including plants and wildlife, respond to environmental factors such as climate change or biotic competition. Such data are typically compositional in nature, and a common challenge in the analysis of ecological compositional data ...

A Data‐Driven Review of Geoscience Research Evolution Using SciBERT‐Based Topic and Network Analysis

open access: yesGeoscience Data Journal, Volume 13, Issue 4, October 2026.
This review synthesises the evolution of global geoscience research from 2004 to 2023 using large‐scale bibliometric evidence. By combining keyword co‐occurrence network analysis with SciBERT‐based topic modelling, it identifies major paradigm transitions from geology‐centred research to climate‐focused studies and recent data‐ and AI‐driven ...

The late Holocene decline of Trapa natans L. in Northern Poland in the light of new palaeobotanical and geochemical data

open access: yesLimnological Review, 2019
Trapa natans (water chestnut) is an aquatic, thermophilic plant whose decline has been observed in many localities in central Europe during the last decades. In this paper, we present a description of two new T. natans subfossil sites located outside its

FINS—A Global Occurrence Dataset of Fossil Neoselachians From the Cretaceous to the Quaternary

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 10, October 2026.
ABSTRACT Motivation Modern sharks, rays and skates (Neoselachii) are a diverse, globally distributed and ecologically important group. They possess a rich, geologically extensive and well‐documented fossil record that provides a powerful basis for studying their macroevolution, paleoecology and biogeography.
