Diversity

open access: yesJournal of Combinatorial Theory, Series A, 2021
Given a family $\mathcal F\subset 2^{[n]}$, its diversity is the number of sets not containing an element with the highest degree. The concept of diversity has proven to be very useful in the context of $k$-uniform intersecting families. In this paper, we study (different notions of) diversity in the context of other extremal set theory problems.

Structure, Function and Diversity of the Healthy Human Microbiome

open access: yesNature, 2012
Studies of the human microbiome have revealed that even healthy individuals differ remarkably in the microbes that occupy habitats such as the gut, skin and vagina. Much of this diversity remains unexplained, although diet, environment, host genetics and

Experimental assessment of downstream environmental DNA patterns under variable fish biomass and river discharge rates

open access: yesEnvironmental DNA, 2023
The development of environmental DNA (eDNA) methods toward implementation as a cost‐effective, nonlethal tool for fish biomonitoring in lotic environments requires insights on the temporal and spatial distribution of eDNA in river systems. Yet, little is

Conspicuousness, phylogenetic structure, and origins of Müllerian mimicry in 4000 lycid beetles from all zoogeographic regions

open access: yesScientific Reports, 2021
Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied
