Opis: Ticks of the genus Haemaphysalis are important vectors of various pathogens, yet their ecology and distribution remain poorly documented in certain regions. This study investigated the seasonal patterns, habitat preferences, and population densities of the dominant Haemaphysalis punctata, alongside the occurrence of Hae. concinna beyond its previously known range in the Karst Edge, Slovenia. Sampling was conducted at five sites encompassing pastures and forest habitats, targeting both adult and nymph stages. Hae. punctata was the dominant species (96.3% of sample size), with 47 males, 55 females, and 393 nymphs recorded, and it was present at all sites except the forest habitat in Osp. Most Hae. punctata ticks (70.7%) were collected from pastures, and the rest from the forest. Adults were detected throughout most of the year, but none were recorded between mid-June and mid-September. Nymphs occurred throughout much of the sampling period, with high abundances in spring and from early August to midOctober; they were absent in December-January and reappeared in February. Seasonal densities of Hae. punctata per 100 m² ranged from 0.21 at Osp to 10.36 individuals at Zazid (all pastures), up to over 30-fold higher than Hae. concinna at sites when both species occur concurrently. The latter was rare, with 4 males, no females, and 15 nymphs (3.7% of sample), and was recoreded at three sites: pastures in Osp and Hrastovlje, and forests in Zazid and Hrastovlje, over a period from mid-April to early July. Hae. concinna often co-occurred with Hae. punctata adults or nymphs. These findings confirm the dominance of Hae. punctata across studied habitats and document the first evidence of Hae. concinna in new localities along the Karst Edge, representing an extension of its known distribution in Slovenia. The study underscores the influence of habitat type on tick abundance and seasonality and provides critical baseline data for monitoring tick populations and potential vector-borne disease risks in the region.

Opis: We investigate a Dirichlet series involving the Fourier-Jacobi coefficients of two cusp forms (F,G) for orthogonal groups of signature ((2,n+2)). In the case when (F) is a Hecke eigenform and (G) is a Maass lift of a Poincaré series, we establish a connection with the standard (L)-function attached to (F). What is more, we find explicit choices of orthogonal groups, for which we obtain a clear-cut Euler product expression for this Dirichlet series. Through our considerations, we recover a classical result for Siegel modular forms, first introduced by Kohnen and Skoruppa, but also provide a range of new examples, which can be related to other kinds of modular forms, such as paramodular, Hermitian, and quaternionic.

Opis: Fermat's little theorem provides a classical and widely used test for primality: if $n$ is prime and $\gcd(a,n)=1$, then \[ a^{n-1}\equiv 1 \pmod n. \] Composite integers satisfying this congruence are called Fermat pseudoprimes to base $a$, and they represent a fundamental obstruction to Fermat-type primality tests. A classical result of Erd\H{o}s shows that, for each fixed base $a\geq 2$, the set of such numbers has asymptotic density zero. In this note we give a short and elementary proof of this density-zero property for Fermat pseudoprimes, based on ideas of Erd\H{o}s and Niven.
