Abstract Araucaria angustifolia (Bertol.) Kuntze is an indigenous conifer tree restricted to the southern region of South America that plays a key role in dynamics regional ecosystems where forest expansion over grasslands has been observed. Here, we evaluate changes intrinsic water use efficiency (iWUE) and basal area increment (BAI) this species response atmospheric CO 2 , temperature precipitation last century. Our investigation based on tree‐rings taken from trees located grassland sites...
Abstract Araucaria angustifolia (Bertol.) O. Kuntze (Araucariaceae) is a Neotropical tree, widely distributed in subtropical mountain rain forests and nearby natural grasslands of Southern Brazil. This species produces annual growth rings, but its dendroclimatic potential barely known. In the present paper, long‐term patterns A. were investigated using ring time series association to climate over last century. Wood cores trees growing forest grassland habitats obtained with an increment...
In this article we investigate how invasion by Pinus taeda L. alters plant community composition and functional traits in sand dunes. invaded psammophilous vegetation southern Brazil, randomly selected 15 P. individuals measured their age based on the number of growth rings. For each tree, sampled 1 m2 quadrats beneath 2 m away its crown. quadrat, assessed non-graminoid performed a multivariate analysis variance. Data species' were scaled up to level, variations compared tree linear...
Abstract Anthropogenic fire is a worldwide event that affects many ecosystems and organisms. In Southern Brazil, grassland management with has been highly employed since the mid‐18th century. Although practice regulated by federal law (prescribed fire), there no detailed information about impacts of this on small, non‐volant fauna. We evaluated effect anuran species richness community composition in Brazilian areas have adopted for more than 15 years. Our results show burning practices lead...
Large tropical tree samples are driving new research in dendrochronology. The development of imaging tools for these substantial represents a significant challenge. Specifically, tree-ring measurements strongly associated with images acquired through scanning, an A3 large-format scanner being the preferred choice sizable samples. However, literature lacks information about image distortions resulting from this approach. To address gap, we developed system comprising table, mobile lift, and...
Mecanismos de dispersão diásporos e recrutamento plântulas evitam a competição intra-específica possibilitam colonização novos ambientes. Em áreas transição entre florestas vegetação campestre esses processos não são aleatórios, sim associados muitas vezes indivíduos lenhosos isolados em tais campo ou formações arbustivas. No sul do Brasil, as Florestas com Araucária formam mosaicos campestres observa-se o avanço da floresta sobre os campos. O estudo teve como objetivo avaliar chuva sementes...
Edge effects are a major cause of natural dynamics fragmented forests; however, studies that evaluate edge during the lifetime trees relatively rare. Through long-term perspective tree growth, dendroecology can contribute to better understanding influence effects. In order frame our interpretation, we raised following hypotheses: (1) located close forest have lower growth rates compared growing far from edges, and (2) climate sensitivity naturally on is different in interior. This study was...
