Multiproxy reconstructions of fire regimes in forest ecosystems can provide a clearer understanding of past fire activity and circumvent some limitations of single proxy reconstructions. While inferring fire history from scars in trees is the most pr

Detailed studies of Chironomidae fauna can yield a reliable tool to evaluate the effects of climatic change and anthropogenic disturbances over freshwater ecosystems. Using modern chironomid remains deposited in surface sediment samples of 27 lakes l

The Younger Dryas (YD) impact hypothesis posits that fragments of a large, disintegrating asteroid/comet struck North America, South America, Europe, and western Asia ~12,800 years ago. Multiple airbursts/impacts produced the YD boundary layer (YDB),

Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regiona

A new assemblage of fossil beetles of Upper Pleistocene age, dated between 15,754 and 14,697 cal yr BP, is described and interpreted based on cluster analysis. In this study, we present an analysis on the taxonomic composition, and the paleoenvironme

We present a vegetation reconstruction based on high-resolution analysis of two pollen, seeds, and charcoal records between ∼16,000 and 12,800 cal yr BP. Pollen records show the dominance of non-arboreal and aquatic pollen types, mainly Poaceae, As

Tephra layers in lake sediment cores are regularly used for tephrostratigraphy as isochronous features for dating and recording eruption frequencies. However, their value for determining volcanic eruption size and style may be complicated by processe

Mediterranean-type climate (MTC) ecosystems are characterized by recurrent wildfires. Although the majority of wildfires are human-ignited, non-anthropogenic (i.e., natural) wildfires are common in all MTC regions except central Chile. The low freque
