The facies distribution and palaeobotanical identity of fossil charcoal is described from the Upper Carboniferous (Westphalian A–B) Joggins section, Nova Scotia, in order to examine the fire ecology of early Westphalian floodplains. Three charcoal assemblages are noted. Assemblage (1) consists of channel sandstone bodies, containing beds of calcrete breccia, cordaite logs (up to 3 m long), and ...

Podocarpus drouynianus and P. spinulosus are two unusual conifers restricted to southwestern and eastern Australia, respectively. The species are morphologically similar and genetically closely related to each other but rather distant from other members of the subgenus Foliolatus. Both species have retained ancestral podocarp characteristics such as dioecy, wind pollination, and large, animaldi...

Abstract Background Fire strongly affects animals’ behavior, population dynamics, and environmental surroundings, which in turn are likely to affect their immune systems exposure pathogens. However, little work has yet been conducted on the effects of wildfires wildlife disease. This research gap is rapidly growing importance because becoming globally more common severe, with unknown impacts di...

1. Fire is important in the dynamics of savanna–forest boundaries, often maintaining a balance between forest advance and retreat. 2. We performed a comparative ecological study to understand how savanna and forest species differ in traits related to fire tolerance. We compared bark thickness, root and stem carbohydrates, and height of reproductive individuals within 10 congeneric pairs, each c...

Overview Quaking aspen is generally considered to be a fire-adapted species because it regenerates prolifically after fire, and it can be replaced by more shade-tolerant tree species in the absence of fire. As early-successional aspen stands transition to greater conifer-dominance, they become increasingly fire prone, until fire returns, and aspen again temporarily dominate. While this disturba...
