The system of plates in the basal part of the wing veins in Diptera (Insecta)

(Plovdiv University "Paisii Hilendarski", 2026-02-05) Hubenov, Zdravko

The sclerites (plates) from which the wing veins begin in the various families of Diptera are scrutinized. A general plan of the sclerites and their localization between the axillary area and the vein system are presented. Some morphological differences in 6 families are considered.

Some new records of terrestrial snails from coastal continental Tanzania

(Plovdiv University "Paisii Hilendarski", 2026-04-21) Georgiev, Dilian

This paper presents new records of nine terrestrial gastropod species collected from the coastal area of Bagamoyo, Tanzania, in early 2026. The findings include the first record of the introduced snail Gastrocopta servilis (Gould, 1843) for Tanzania, marking only its second known occurrence on the African continent. Additionally, the presence of Streptostele acicula (Morelet, 1877) is confirmed for the East African coast, and Opeas delicatum Taylor, 1877 is reported from a new locality outside of Amani.

New locality of Rana graeca Boulenger, 1891 and a previously undescribed threat for the species from Western Rhodopes, Bulgaria

(Plovdiv University "Paisii Hilendarski", 2026-04-21) Mollov, Ivelin; Chetalbashev, Teodor

A new locality for Rana graeca is reported from the Western Rhodopes Mountains. Although the location of the observation falls within the already known range of the species, a newly recorded threat for this and other anuran species is described. In addition habitat characteristics and coordinates are provided.

Hidden diversity: noteworthy cortinarioid fungi (Cortinarius s. l.) from relict deciduous forests of Strandzha Mountain, Bulgaria

(Plovdiv University Press "Paisii Hilendarski", 2026-04-10) Assyov, Boris; Radoukova, Tzenka

The paper communicates interesting findings of cortinarioid fungi from relict deciduous forests in Strandzha Mt. (Bulgaria). Five species were revealed based on the above-ground collecting approach coupled with DNA-barcoding, targeting the nrITS region. These are Calonarius albertii, Ca. violaceipes, Cortinarius pseudocollinitus, Phlegmacium perpallens, and P. scaurocaninum. They are recorded for the first time from Bulgaria and represent their first molecularly supported findings in Southeastern Europe. The collections are illustrated and commented on, and brief morphological data are provided.

Evaluation of vegetation development in reclaimed sites using the NDVI

(Plovdiv University Press "Paisii Hilendarski", 2026-04-10) Petrov, Petar; Stefanova, Veneta

This study investigates the recovery processes in reclaimed sites (an old embankment from copper mining), which was reclaimed by various methods in 2010. For the purpose of this study, the maximum average values of the NDVI index for 2018-2021 were used. According to the results of the study, restoration processes are taking place in recultivated areas, and a tendency for the index to increase over time has been observed. The extent of the restorative process depends on the remedial measures that have been carried out. In the reclamation of sites disturbed by copper mining, liming has been found to be a key amelioration. The use of a NDVI index is a viable and reliable method of tracking site recovery and on-going soil formation process.
