Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

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.

Georeferencing for Research Use (GRU): An integrated geospatial training paradigm for biocollections researchers and data providers [PDF]

Research Ideas and Outcomes, 2018
Georeferencing is the process of aligning a text description of a geographic location with a spatial location based on a geographic coordinate system. Training aids are commonly created around the georeferencing process to disseminate community standards
