From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas

The Journal of Wildlife Management, EarlyView.
Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.
