Bioindicators in radiation protection [PDF]
Brazilian Archives of Biology and Technology, 2008 Biodosimetry is the evaluation of absorbed dose using bioindicators. Among chromosomal aberrations, scoring of dicentrics from peripheral human blood has been used as gold standard for biodosimetry, although in case of large scale incidents its use presents some drawbacks. Advances in technology have led to new investigations allowing or permitting the

Underground Lag: Fungal Community and Edaphic Legacies After Disturbance
Land Degradation &Development, EarlyView.ABSTRACT Páramos are neotropical mountain ecosystems that regulate water and store large amounts of carbon, but are increasingly degraded by agriculture and grazing. Although native vegetation often recolonizes after abandonment, belowground recovery remains poorly understood.

A simple index for assessing cumulative human impacts on mountain lakes
Limnology and Oceanography: Methods, EarlyView.Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Wilting wildflowers and bummed‐out bees: Climate change threatens US state symbols
People and Nature, EarlyView.Abstract Species designated as state symbols in the United States carry cultural importance, embody historical heritage and maintain long‐standing linkages to Indigenous traditions. However, they are threatened by climate change and even face the risk of local or global extinction.

Exploring Costa Rica's fungal trends: Insights from digitized specimens
PLANTS, PEOPLE, PLANET, EarlyView.Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.
