(NATL ACAD SCIENCES, 2006-01-10)Species invasions are a principal component of global change, causing large losses in biodiversity as well as economic damage. Invasion theory attempts to understand and predict invasion success and patterns of spread. ...
-
(GEOLOGICAL SOC AMER, 2007-11)This study uses stable isotope variation within individual Mio-Pliocene paleosols to investigate subkilometer-scale phytogeography of late Miocene vegetation change in southeast Asia between ca. 8.1 and 5 Ma, a time interval ...
-
(MDPI, 2020)Physiological thermal limits of organisms are linked to their geographic distribution. The assessment of such limits can provide valuable insights when monitoring for environmental thermal alterations. Using the dynamic ...
-
(Elsevier, 2012)We present detailed pollen and charcoal records from Lago Pichilafquén (~41°S) to decipher the effects of climate change and varying disturbance regimes on the composition and structure of the vegetation on the Andean ...
-
(SPRINGER, 2008-04)We assessed differences in the development rates among anchoveta, E. ringens populations from the extremes of its range under different temperatures. Time to hatch decreased with increasing temperature but there was no ...
-
(RESILIENCE ALLIANCE, ACADIA UNIV, BIOLOGY DEPT, 2006-06)Although there is general agreement among conservation practitioners about the need for ( 1) social involvement on the part of scientists; ( 2) interdisciplinary approaches; ( 3) working on local, regional, and global ...
-
(Springer, 2015)Correlations among and identification of the source volcanoes for over 60 Late Glacial and Holocene tephras preserved in eight lacustrine sediment cores taken from small lakes near Coyhaique, Chile (46 degrees S), were ...
-
(Taylor & Francis, 2016)Cheilodactylus variegatus is a common benthivorous marine fish inhabiting in rocky subtidal habitats in the eastern south Pacific coast of Chile and Peru. However, its biology and ecology are relatively understudied and ...
-
(Elsevier, 2020)The first Global Assessment of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) found widespread, accelerating declines in Earth's biodiversity and associated benefits to people ...
-
(Wiley, 2014)Aim: To assess the long-term impacts of landscape fire on a mosaic of pyrophobic and pyrogenic woody montane vegetation. Location: South-west Tasmania, Australia. Methods: We undertook a high-resolution multiproxy ...
-
(Springer, 2011-11)A common assumption in behavioral ecology is that the valuation of a resource by consumers depends on the energetic value of the resource itself. Nevertheless, the value of a resource may be relative to the condition of ...
-
(Elsevier, 2020)By virtue of its location in the southern mid-latitudes, northwestern Patagonia (40 degrees-44 degrees S) offers the opportunity to unravel the mechanisms involved in the initiation and propagation of paleoclimate signals ...
-
(OPULUS PRESS UPPSALA AB, 2007-04)Questions: (1) What are the roles of regional climate and plant growth rate for seedling establishment during ENSO rainy pulses along the western coast of South America? (2) What is the water threshold for tree seedling ...
-
(MDPI, 2021)Simple Summary Triatoma infestans is the main vector of the Chagas disease transmission and has been for years one of the main sanitary problems in Bolivia, particularly for the movement between isolated population to ...
-
(Hindawi, 2016)Within a woody plant species, environmental heterogeneity has the potential to influence the distribution of genetic variation among populations through several evolutionary processes. In some species, a relationship between ...
-
(2010-04-06)The aim of this study was to investigate, during the summer of the year 2008, the variation in leaf water and photosynthetic characteristics of Eucryphia cordifolia Cav. (Cunoniaceae) along its broad latitudinal ...
-
(Elsevier, 2015)Disentangling the roles of paleofires and explosive volcanism from climatic drivers of past vegetation change is a subject insufficiently addressed in the paleoecological literature. The coastal region of the Chilo e ...
-
(Elsevier, 2014)We present a detailed record from Lago Lepué to examine vegetation, climate and fire-regime changes since the Last Glacial Maximum (LGM) in central-east Isla Grande de Chiloé (43°S), northwestern Patagonia. Precipitation ...
-
(Wiley, 2020)Methylmercury is a neurotoxin that bioaccumulates from seawater to high concentrations in marine fish, putting human and ecosystem health at risk. High methylmercury levels have been found in the oxic subsurface waters of ...
