Occupational Contact Urticaria, Protein Contact Dermatitis and Concomitant Airway Diseases in the Finnish Register of Occupational Diseases in 2005–2020: Main Causes and Occupations at Risk

Contact Dermatitis, EarlyView.
This Finnish registry study shows that concomitant occupational asthma and rhinitis are common in patients with occupational contact urticaria or protein contact dermatitis, often sharing the same exposure. When evaluating occupational immediate allergy, both skin and airway symptoms should be considered.

Phytogeographic Transition Areas Hide Floristic Diversity in Hyper-Arid Environments (Sharaan Natural Reserve, NW-Saudi Arabia)

Diversity
Phytogeographic transition zones are often considered areas rich in biodiversity due to their ecological and landscape diversity. This study constitutes the first floristic investigation of the Sharaan Natural Reserve (SNR) located in the northwest of ...

The value of saltbush revegetation for biodiversity in a highly fragmented landscape

Conservation Science and Practice, EarlyView.
Saltbush revegetation provides limited value for faunal biodiversity. Saltbush has the lowest species richness and diversity of ants, spiders, and birds. Remnant habitats continue to provide the most important habitats for native species. Abstract Secondary salinization is a significant global issue affecting up to 1 billion hectares of land, impacting

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

Grassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

Insect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...
