Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Small ball probabilities of Gaussian fields

Probability Theory and Related Fields, 1995
Let \(X(t)\), \(t \in R^d\), \(d \geq 1\), be a real-valued Gaussian field with mean zero. Lower bounds on the small ball probability, i.e. \(P(\sup_{0 \leq t \leq 1} |X(t)|\leq x)\) for small \(x\)'s, are given for two classes of processes: Gaussian fields satisfying \(E |X(s) - X(t)|^2 \leq \sigma^2(|s - t|)\) for some nondecreasing function \(\sigma(

Functional Quantization and Small Ball Probabilities for Gaussian Processes

Journal of Theoretical Probability, 2003
Quantization consists in studying the \(L^r\)-error induced by the approximation of a random vector \(X\) by a vector (quantized version) taking a finite number \(n\) of values. This paper investigates this problem for Gaussian random vectors in an infinite-dimensional Banach space and in particular, for Gaussian processes.
