Land cover change and vegetation trends in South Darfur Sudan using dynamic world

Land use and land cover change (LULCC) in semi-arid regions provides important insights into environmental dynamics under climate variability and socio-political disturbance. This study investigated the spatiotemporal dynamics of land cover, vegetation greenness, and climate vari...

A composite disturbance index for monitoring Sudanian dryland forests: structural and compositional indicators diverge under anthropogenic pressure

We developed and tested a field-based Composite Disturbance Index (CDI) for monitoring anthropogenic pressure in Sudan dryland forest, integrating stump density, partial extraction, grazing, agriculture, and fire into a single normalized score, and evaluated its performance again...

Splitting the bill for bits: Shapley-based cost sharing in European telecommunications

This paper addresses the ongoing debate in the European Union over whether a “Sender Party Network Pays” regulation would solve underinvestment in very high-capacity networks and enhance the competitiveness of the European telecommunications sector. Operators argue that large con...

Alpine forest genomics—advances in the research field and perspectives ahead

Abstract Key message Alpine or mountainous forest genomics research is rapidly moving from classic population genetic studies toward exploring population environmental adaptation to address climate vulnerabilities. For alpine conifers in particular, future progress in sustainable...

Mapping and monitoring land usage changes of gum Arabic belt in armed conflict-disturbed areas to support sustainable management of the belt

Abstract The Gum Arabic Belt (GAB) in Sudan play a key role in sustaining rural livelihoods, supporting biodiversity, and delivering essential ecosystem services. However, this fragile dryland ecosystem is increasingly threatened by armed conflict, large-scale displacement, land...

Dynamical Time Field Cosmology: A Scale‑Inversion Framework for Dark Phenomena and Cosmic Cycles

English version: This record contains two bilingual (English–Hungarian) research documents presenting a unified cosmological framework in which time is formulated as a dynamical physical field coupled to spacetime geometry and local measurement scales. The model interprets dark e...

Integrative Faunistic, Ecological, and Molecular Study of Harpirhynchus dusbabeki and Blankaartia acucutellaris Associated with European Passerines

Parasitic skin mites associated with wild birds are understudied members of host–parasite systems in Europe despite their ecological importance, potential role as disease vectors, and effects on host fitness. Using a multidisciplinary approach combining faunistic, ecological, and...
