AbstractIn this study, we establish the seasonal variation of the Culpeo fox’s diet in a seasonal ecosystem of south-central Chile. By scat analyses, 21 prey taxa were identified, 16 were animal and five were plant species. Mammals (88.47%) were the main biomass contribution with small seasonal fluctuations. Plants contributed the most to the differences observed in all seasons since they showed very marked changes. We determined that the Culpeo fox inhabiting the Andes of south-central Chile feeds mainly on small non-native mammals all year round, and supplements its diet opportunistically from items whose abundance oscillates seasonally.

Intercultural education in Chile has focused on early childhood for more than a decade. Different measures have been implemented to strength an intercultural approach in preschools. The most outstanding has been the connection of intercultural preschools with Indigenous communities. However, these educational policies have not been accompanied by adequate resources and teacher preparation, resulting in significant shortcomings in the collaboration between Indigenous communities and preschools. To address the relevance of Mapuche (People of the Land; Indigenous inhabitants of south-central Chile and southwestern Argentina; speakers of Mapudungun) communities in intercultural preschools, this study created and implemented a pilot initiative. Using a decolonial and critical pedagogy-of-place approach, the main findings show that educators began considering Mapuche communities beyond families, discussed the role of urban Mapuche communities, and improved ethical practices to work with Indigenous communities. These findings lead me to propose recommendations in reference to policies and teacher education.

Mammals often consume fleshy fruits and disperse significant quantities of the enclosed seeds. In southeastern Alaska, Brown Bears (Ursus arctos) are among the most important dispersers of seeds for the numerous plant species producing fleshy fruits, because these bears are abundant, often eat large quantities of fruit, and commonly excrete seeds in germinable condition. Scat analyses showed that Brown Bears on Chichagof Island ate increasing quantities of fruit through summer and fall. Scats commonly contained several thousand seeds, often of two or more species. Four kinds of seeds of fleshyfruited plants that normally grow in forest understory germinated at similar levels when experimentally deposited (in bear scats) in the two most common habitats (forest and muskeg), suggesting that habitat distribution of these plants is not determined simply by germination patterns. Although seed passage through bear digestive tracts and the composition of scats are known to affect germination rates to some degree, the most important role of bears in seed dispersal is probably transport.

In Chile, 49.1% of the national territory is affected by soil degradation (including erosion and loss of soil organic matter), whereby of the 51.7 Mha that have been historically associated with agricultural-livestock and forestry activities, only 35.5 Mha are being used at the present. Consequently, soil degradation has resulted in the release of about 11.8 Gg yr−1 of carbon (C) equivalent (CO2eq) to the atmosphere. Silvopastoral systems (SPS), however, can increase soil organic C (SOC) through sequestration (C→SOC), improve ecosystem services, and have been internationally recommended for sustainable land use. Therefore, it was proposed to determine the effects of SPS on soils, over five years, in degraded sites that were located in the Ranchillo Alto (SPS-RA) (37°04′52″ S, 71°39′14″ W), Ñuble region. The sites were rated according to previous canopy disturbance levels (+) as follows: open (Op)+++, semi open (SOp)++, and semi closed (SC)+. The analysis was performed on different physical and chemical soil properties (0–5 and 5–20 cm depths), that were expressed as soil indicators (SIND) for chemical and physical properties, which were used to calculate a soil quality (SQ) index (SQI). The results indicated overall SQI values of 37.6 (SC) > 29.8 (Op) > 28.8 (SOp), but there were no significant variations (p < 0.05) in physical SQ, whereas chemical SQ varied in all conditions, mostly at 0–5 cm in Op and SOp. Increases of SOC were also observed (2015–2018 period) of 22.5, 14.5, and 4.8 Mg ha−1 for SOp, Op, and SC, respectively, showing that SPS promote the reclamation of Ranchillo Alto soils.

The temperate deciduous species Nothofagus glauca (Phil.) Krasser exhibits characteristics commonly found in fire-adapted vegetation, yet the role of fire in the evolutionary history of the vegetation in south-central Chile has not been well investigated. We examined the effects of a wildfire on early succession in a Nothofagus glauca forest in the Coastal Cordillera of south-central Chile by comparing data from a burned forest to the vegetation in an adjacent, unburned stand.

The scarcity of middle Holocene radiocarbon dates in different regions of the Andes has been interpreted as an indicator of discontinuity in human occupations in response to adverse environmental conditions due to marked aridity. In the subtropical Andes of north-central Chile and adjacent areas, this paucity has been detected in radiocarbon ages between 8000 and 6000 cal BP. A systematic programme of cave excavations with detailed chronologies in the Combarbalá area in the Andean western foothills at 31°S allows questioning the role these spaces and ecosystems played for hunter-gatherers throughout the Holocene. The elusive record of dateable material has been addressed by excavating deposits under rock-shelters which tend to trap sedimentary material. This dataset has been compared with the available climate records and shows a collation between the onset of various site chronologies during the early-to-middle Holocene and periods of extreme aridity. The organization of mobility and the role of Andean foothills for hunter-gatherer settlements is reviewed. Resource availability in the area, namely fresh water supply, good-quality toolstones, faunal resources, and shelters, attracted mobile populations to these environments as indicated by our records as well as others in the broader region.
