The Andean uplift and the concomitant aridification drove the rapid diversification of several plant lineages that were able to colonize warmer and drier habitats at low elevations and wetter and colder habitats at high elevations. These transitions may be facilitated by shifts in plant strategies to cope with drought and cold, which in turn can tr...
Introduction
Understanding the relationships between taxonomic, functional, and phylogenetic diversity and endemism across environmental gradients is essential for elucidating the eco-evolutionary mechanisms that shape local plant communities.
Methods
A database was compiled from field surveys, national herbarium records, and virtual records of pe...
The environmental filtering hypothesis predicts that abiotic factors restrict communities by selecting species capable of survival and persistence under specific conditions, resulting in variations in beta diversity, phylogenetic clustering, and niche differentiation among communities when studying environmental gradients. Cushion bogs and high-alt...
In southern South America, zonal flora, defined by macroclimatic conditions, is strongly influenced by an aridity filter near 29°S. Cushion bogs, high-altitude wetlands along the Andes, display homogeneous flora with cushion species dominance, contrasting with zonal vegetation. Despite being influenced by microclimatic conditions, these ecosystems...
The changing climate during the Cenozoic affected the diversity of plants in Patagonia, as species richness tends to increase during warm periods and decrease during cold periods. Precipitation is a significant factor shaping diversity, as shown in the case of central Chile during the Miocene. This study presents a reconstruction of the climate and...
We assess the Tropical Niche Conservatism Hypothesis in the genus Escallonia in South America using phylogeny, paleoclimate estimation and current niche modelling. We tested four predictions: (1) the climatic condition where the ancestor of Escallonia grew is megathermal; (2) the temperate niche is a derived condition from tropical clades; (3) the...
Armoured dinosaurs are well known for their evolution of specialized tail weapons—paired tail spikes in stegosaurs and heavy tail clubs in advanced ankylosaurs1. Armoured dinosaurs from southern Gondwana are rare and enigmatic, but probably include the earliest branches of Ankylosauria2–4. Here we describe a mostly complete, semi-articulated skelet...
This study examines the new fossiliferous site Huapilacuy II of Mid-Holocene age (7,344±51-6,865±58 cal years BP.) located in the northwestern coast of the Isla Grande de Chiloé. This area was not affected by the successive Pleistocene glaciations, and therefore it presents a biogeographic relevance as a potential area of refugia and stability for...
Andean uplift and the concomitant formation of the Diagonal Arid of South America is expected to have promoted species diversification through range expansions into this novel environment. We evaluate the evolution of Argylia, a genus belonging to the Bignoniaceae family whose oldest fossil record dates back to 49.4 Ma. Today, Argylia is distribute...
Armoured dinosaurs are well known for forms that evolved specialized tail weapons: paired tail spikes in stegosaurs, and heavy tail clubs in advanced ankylosaurs1. Armoured dinosaurs from southern Gondwana are rare and enigmatic, but likely include the earliest branches of Ankylosauria2-4. Here, we describe a mostly complete, semiarticulated skelet...
Ripartites tricholoma collected in the Nature Reserve Altos de Cantillana, near Santiago is described as a first record of this fungal genus and species for Chile. This is a contribution to the knowledge of fungal diversity in Nothofagus macrocarpa dominated forest close to its northern limit of distribution.
Understanding why some plant lineages move from one climatic region to another is a mayor goal of evolutionary biology. In the southern Andes plant lineages that have migrated along mountain ranges tracking cold-humid climates coexist with lineages that have shifted repeatedly between warm-arid at low elevations and cold habitats at high elevations...
A new fossil cycad species, Sueria laxinervis, is described from the Upper Cretaceous (Maastrichtian) Quiriquina Formation in Cocholgüe, Bíobío Region, Chile. The generic assignment is supported by the taeniopterid-type leaf with haplocheilic stomata and sinuate anticlinal walls of leaf epidermal cells, while S. laxinervis clearly differs from the...
The evolution of maize (Zea mays L.) is highly controversial given the discrepancies related to the phenotypic and genetic changes suffered by the species, the incidence of human groups and the times in which these changes occurred. Also, morphological and genetic traits of crops are difficult to evaluate in the absence of fossils macro-botanical r...

The current relationship between leaf traits and environmental variables has been widely used as a proxy for climate estimates. However, it has been observed that the phylogenetic relationships between taxa also influence the evolution of climatic related leaf traits, implying that the direct use of the physiognomy–climate relation should be correc...
Several studies have demonstrated the contribution of northern immigrants to the flora of the tropical Andes-the world's richest and most diverse biodiversity hotspot. However, much less is known about the biogeographic history and diversification of Andean groups with southern origins, although it has been suggested that northern and southern grou...

El género Nothofagus (Nothofagaceae, Fagales), posee 35 especies con distribución disyunta en Oceanía y el sur de Sudamérica. Está compuesto por 4 subgéneros: Brassospora, Nothofagus, Fuscospora y Lophozonia, donde 10 especies pertenecientes a los tres últimos subgéneros se pueden encontrar en los bosques templados y patagónicos del sur de Sudaméri...
The relationship between the landmass of the Southern Hemisphere has been broadly highlighted in the literature since Hooker's times, where Nothofagus is considered key to understand the biogeographical history of the western Gondwanland.
Rare species frequently occur in areas with microclimatic conditions that are atypical for their regions, but that were more common in the past, and that probably have operated as climatic refugia for a long time. Myrceugenia correifolia is a rare arboreal species that grows in deep canyons and hilltops of the Coast Range of north-central Chile bet...
The Sierra Baguales, situated north of the Torres Del Paine National Park in the Magallanes region of southern Chile, shows a well-exposed stratigraphic sequence ranging from the Late Cretaceous to late Pliocene, which presents a unique opportunity to study the evolution of sedimentological styles and trends, palaeoclimate changes, and tectonic eve...
Cone scales and leaves of the Araucariaceae are reported from the Loreto Formation in Río de Las Minas, Punta Arenas, Chile. Two types of cone scales including one new species, Araucaritesalatisquamosus are recognized. They are similar to Araucaria section Eutacta. Two types of leaves are assigned to Araucaria nathorstii Dusén, and one new type is...
An important tenet of biogeography and comparative ecology is that
disjunct assemblages in similar physical environments are
functionally more similar to each other than to assemblages from
other environments. Temperate rainforests in South America, New
Zealand and Australia share certain physiognomic similarities, but
we are not aware of any stati...
This study examines the Phenotypic variability of maize from the Archaeological site Caserones-1, comparing seven characters in samples from two periods: Formative and Late Intermediate (LIP) (cal. 20-1.020 d.C.). Considering the ancient relationship between this species and several human groups in America (ca. 7.500 AP), as well as the general ten...
Aim
We used fossil and phylogenetic evidence to reconstruct climatic niche evolution in Nothofagus , a Gondwana genus distributed in tropical and temperate latitudes. To assess whether the modern distribution of the genus can be explained by the tropical conservatism hypothesis, we tested three predictions: (1) species from all Nothofagus subgenera...
Myrceugenia rufa is an endangered shrub endemic to the coast range of central Chile, which has suffered strong degradation during recent decades. We developed nine microsatellite markers for this species and tested them on M. correifolia, M. lanceolata, and M. exsucca. Six loci amplified and were polymorphic in all species; the remaining loci were...
Phylogenetic conservatism of tolerance to freezing temperatures has been cited to explain the tendency of plant lineages to grow in similar climates. However, there is little information about whether or not freezing resistance is conserved across phylogenies, and whether conservatism of physiological traits could explain conservatism of realized c...
Aim Shifts between the western South American sclerophyll and winter-rainfall desert biomes and their relationship to climatic niche evolution and aridity development were investigated in the South American endemic geophytic Leucocoryne (Alliaceae) clade.
Location Western South America.
Methods We constructed a molecular phylogeny (ITS), estimate...
Broad‐scale richness gradients are closely associated with temperature and water availability. However, historical and evolutionary processes have also contributed to shape current diversity patterns. In this paper we focus on the potential influences of Pleistocene glaciation and phylogenetic niche conservatism (the tendency for traits to be maint...
The statistical analysis of published Paleocene–Late Miocene palynological data from Patagonia supports several major stages of vegetation. These stages represent distinctive floral assemblages, both in composition and structure. Detrended correspondence analysis shows that during the Paleocene, southern South America was dominated by Australasian,...
We thank Finger et al. (2013) for their discussion of our paper and appreciate their honesty in retracting the proposed Late Miocene-Pliocene age for the Navidad Formation, due to misidentification of the foraminifer index species in question. In fact, although we suspected all along that these species may have been misidentified, such an allegatio...
The age of the Navidad Formation in central Chile has always been controversial, mainly due to the conflicting age ranges indicated by its macro- and microfossils. Macrofossils are generally interpreted as having been reworked from older, Early to Middle Miocene strata, whereas a Late Miocene-Pliocene age has been accepted on the basis of planktoni...
Premise of the study:
The temperate forests of southern South America were greatly affected by glaciations. Previous studies have indicated that some cold-tolerant tree species were able to survive glacial periods in small, ice-free patches within glaciated areas in the Andes and in southern Patagonia. Here we asked whether populations of the meso...
Palynological assemblages recovered from the Navidad Formation in outcrops of the Cordillera de la Costa, central Chile, are dominated by wood remains, cuticles, spores and pollen grains and fresh water algae (continental elements) with scarce dinoflagellate cysts, acritarchs, foraminiferal linnings marine palynomorphs) indicating that these assemb...

• Paleobotanists have long used models based on leaf size and shape to reconstruct paleoclimate. However, most models incorporate a single variable or use traits that are not physiologically or functionally linked to climate, limiting their predictive power. Further, they often underestimate paleotemperature relative to other proxies. • Here we qua...
Aim The relationship between the proportion of species with an entire leaf margin (pE) and mean annual temperature (MAT) is one of the most powerful tools for estimating palaeotemperatures. However, phylogenetic and phytogeographic constraints on this relationship have remained unexplored. Here we investigate the pE–MAT relationship for modern flor...
Temperature is one of the major abiotic factors influencing distribution and productivity of alpine plant species. Although some edaphic parameters (e.g. soil acidity) have also been suggested as determinants in the spatial distribution of alpine vegetation, there is little background on the importance of soil chemical properties in altitudinal gra...
