BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

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

open access: yesContact 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.

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

open access: yesConservation 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

open access: yesGrassland 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

open access: yesIbis, 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

open access: yesInsect 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 ...

Ethnic Diversity in Compulsory Schooling and Occupational Choices: Can Diversity Increase the Supply in Care‐Oriented Occupations

open access: yesIndustrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT We investigate the effect of ethnic diversity on occupational choices, particularly in care‐oriented occupations which are scarce in many high‐income countries. We use administrative data of all students in Switzerland to study two diversity dimensions: ethnic fractionalization and ethnic polarization.

An updated classification of growth forms in non‐geniculate coralline algae (Corallinophycidae, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be
