Measuring in situ predation by Mysis relicta and observations on underdispersed microdistributions of zooplankton [PDF]

Hydrobiologia, 1982
Described are a method and apparatus that allowin situ measurement of predation on zooplankton byMysis relicta. The method, which can be generalized to other predators, involves lowering paired large-volume (30-1) plankton traps to the depth of interest, with subsequent trapping of the ambient zooplankton assemblage in each trap and release of ...

Geographic distribution of asthma and chronic obstructive pulmonary disease hospitalisations in Australia: 2007-08 to 2009-10 [PDF]

, 2013
This report shows how asthma and chronic obstructive pulmonary disease (COPD) hospitalisations vary across Australia. It also examines the association between these hospitalisation rates and socioeconomic status (SES), remoteness and the proportion of

Joint Postprocessing of Air and Dew Point Temperature Ensemble Forecasts With Machine Learning

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
This study compares two joint probabilistic postprocessing methods for calibrating air and dew point temperature ensemble forecasts. Results show that the bivariate distributional regression network improves uncertainty representation and overall forecast skill, highlighting its potential for operational meteorological applications. ABSTRACT Estimation

On arbitrarily underdispersed Conway-Maxwell-Poisson distributions

, 2020
We show that the Conway--Maxwell--Poisson distribution can be arbitrarily underdispersed when parametrized via its mean. More precisely, if the mean $μ$ is an integer then the limiting distribution is a unit probability mass at $μ$. If the mean $μ$ is not an integer then the limiting distribution is a shifted Bernoulli on the two values $\floorμ$ and $\

Generalized Poisson regression model: modeling count data with overdispersion and underdispersion

, 2019
Dissertação de mestrado em EstatísticaA distribuição de Poisson é uma referência para os modelos de regressão para dados de contagem. No entanto, a restrição de equidispersão, isto é, o valor esperado e a variância condicionais são iguais, não ...

Metabolomic and morphological trait diversity display contrasting patterns in temperate forest tree communities

Ecosphere
Studies of community assembly often explore the role of niche selection in limiting the diversity of functional traits (underdispersion) or increasing the diversity of functional traits (overdispersion) within local communities. While these patterns have

Acute Diarrheal Disease Associated With Climate Variability and Water Supply System Configuration: An Ecological Study in Brazil

Water Environment Research, Volume 98, Issue 9, September 2026.
Acute diarrheal disease rates are associated with seasonality and the type of water supply system. ABSTRACT Acute diarrheal disease (ADD) remains a major public health problem in low‐ and middle‐income countries, where vulnerabilities in water supply systems (WSSs) are associated with increased exposure to disease.

Is "underdispersion" underestimated?

, 2018
We often come across overdispersion in counts. But how about underdispersion? When analysing field trial results, the number of maize plants observed per 2m-long transect, in four randomly chosen transects per plot, from various plots were found to be ...

Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

Journal of Animal Ecology, Volume 95, Issue 9, Page 1522-1538, September 2026.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.

Spatial Distribution and Environmental Factor Analysis of the Invasive Alien Species Spotted Lanternfly (Lycorma delicatula) in South Korea

Entomological Research, Volume 56, Issue 9, September 2026.
ABSTRACT The spotted lanternfly (Lycorma delicatula) is an invasive alien species that has rapidly expanded across South Korea since its population began to surge in 2006. This study analyzed the spatiotemporal distribution patterns and environmental drivers of the species following its nationwide expansion, utilizing national survey data from 2016 to ...
