The last decade has revealed an unexpected fungal diversity associated with natural rocks, often collected in environments influenced by harsh climatic conditions. Yet the phylogenetic affiliations and the taxonomy of many of these extreme fungi, mainly within Dothideomycetes, the largest class of Ascomycota, have only partially been described. In the… (More)

Ants in the tribe Attini (Hymenoptera, Formicidae) maintain a 50 million-year-old lifestyle of co-evolution with symbiotic basidiomycetous fungi which they cultivate as essential source of nutrition. However, other microorganisms have been reported from ant habitats indicating a higher diversity of consistently associated species than established to date.… (More)

Let β > 1 be a non-integer. We consider expansions of the form ∞ i=1 d i β i , where the digits (di) i≥1 are generated by means of a Borel map K β defined on {0, 1} N × [0, β/(β − 1)]. We show existence and uniqueness of an absolutely continuous K β-invariant probability measure w.r.t. mp ⊗ λ, where mp is the Bernoulli measure on {0, 1} N with parameter p… (More)

Consider the set U of real numbers q ≥ 1 for which only one sequence (c i) of integers 0 ≤ c i ≤ q satisfies the equality P ∞ i=1 c i q −i = 1. In this note we show that the set of algebraic numbers in U is dense in the closure U of U .

Let q > 1 be a real number and let m = m(q) be the largest integer smaller than q. It is well known that each number x ∈ Jq := [0, P ∞ i=1 mq −i ] can be written as x = P ∞ i=1 c i q −i with integer coefficients 0 ≤ c i < q. If q is a non-integer, then almost every x ∈ Jq has continuum many expansions of this form. In this note we consider some properties… (More)

This work investigates the Color-Magnitude (C-M) relation for early-type galaxies. The recent WISE and Spitzer infrared surveys have opened up the possibility to study the C-M relation for galaxies in the nearand mid-Infrared. For the C-M relation four different samples from different sources are used, ranging from a Virgo Cluster sample of dwarf… (More)
