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 ...

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...

Rapid Establishment of a Regular Distribution of Adult Tropical Drosophila Parasitoids in a Multi-Patch Environment by Patch Defence Behaviour. [PDF]

, 2011
Females of the larval parasitoid of Drosophila, Asobara citri, from sub-Saharan Africa, defend patches with hosts by fighting and chasing conspecific females upon encounter.

Agricultural Fungicide Mancozeb in Leaf Litter Enhances Survival and Growth of Aedes aegypti (Diptera: Culicidae)

Environmental Toxicology, EarlyView.
ABSTRACT Mancozeb is one of the most widely used agricultural fungicides, exhibiting strong efficacy against a broad spectrum of phytopathogenic fungi. However, its widespread application comes at the cost of environmental contamination. Here, we show the effects of Inga vera leaf litter contamination with Mancozeb on life‐history traits of Aedes ...

Integrating experimental and observational approaches facilitates scaling species interactions to biodiversity patterns

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract To investigate how niche and fitness differences determine the outcome of species interactions and shape local biodiversity patterns, research has typically focused on either simplified experimental systems that test specific mechanisms or observational studies where ...

Testing discharge assimilation strategies to enhance short-range AI-based operational rainfall–runoff forecasts [PDF]

Hydrology and Earth System Sciences
Effective discharge forecasts are essential in operational hydrology. The accuracy of such forecasts, particularly in short lead times, is generally increased through the integration of recent measurements of observed discharge; commonly known as ...

Verification of ensemble forecasts of Mediterranean high-impact weather events against satellite observations [PDF]

Natural Hazards and Earth System Sciences, 2012
Ensemble forecasts at kilometre scale of two severe storms over the Mediterranean region are verified against satellite observations. In complement to assessing the forecasts against ground-based measurements, brightness temperature (BT) images are ...

A Novel Flexible Class of Intervened Poisson Distribution by Lagrangian Approach

Stats, 2023
The zero-truncated Poisson distribution (ZTPD) generates a statistical model that could be appropriate when observations begin once at least one event occurs.

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

Journal of Animal Ecology, EarlyView.
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.

Approaches to Detecting and Modeling Over-and Underdispersion in Alternative Count Data Distributions and an Application of Logistic Regression and Random Forest Modeling to Improve Screening Tools for Tic Disorders in Children

, 2023
This dissertation focuses on theory and application of discrete data methods, particularly approaches to over- and underdispersion relative to the Poisson distribution and an application of random forest and logistic regression modeling.
