(BRITISH HERPETOL SOC, 2006-01)Insuetophrynus acarpicus is a poorly known frog restricted to the temperate forests of the coastal range of Chile (39 degrees 25' S, 73 degrees 10' W). Until recently, this species was known only from one type locality ...
-
(Blackwell, 2011)Aim The Chilean long-tailed snake (Philodryas chamissonis) has a wide distribution across different latitudes and ecosystems in Chile ranging from the south of the Atacama Desert (26 S) to the extremely humid Valdivian ...
-
(2004)The tobacco-feeding race of Myzus persicae (Sulzer), formerly known as M. nicotianae Blackman, was introduced into Chile during the last decade. In order to evaluate the genetic diversity and insecticide resistance status ...
-
(2012)The Chilotan Archipelago and surrounding areas of north-western Patagonia (41°–43°S, 72°–74°W) offer a unique opportunity to study the interplay between the recent genetic and paleoenvironmental evolution on temperate ...
-
(MDPI, 2022)Jubaea chilensis (Molina) Baill., also named Chilean palm, is an endemic species found in the coastal area of Mediterranean sclerophyllous forest in Chile. It has a highly restricted and fragmented distribution along the ...
-
(OXFORD UNIV PRESS, 2007-07)Background and Aims The endemic tree Nothofagus alessandrii (Fagaceae) has been historically restricted to the coastal range of Region VII of central Chile, and its forests have been increasingly destroyed and fragmented ...
-
(Springer, 2012)Colonising populations do not always exhibit founder effects. Common explanations are high levels of immigration and/or reproduction, but few empirical tests have been done. We measured genetic diversity of Nassauvia ...
-
(Elsevier, 2014)Although Phaseolus vulgaris L. is native from the Americas and is currently cultured in diverse areas, verylittle is known about the diversity of symbiotic nitrogen fixing Rhizobium (mycrosymbiont) in many ofthose cultures. ...
-
(Sociedad Espanola de Microbiologia, 2013)Decreasing quality of forest habitats is among the major factors leading to a loss of epiphytic lichen diversity. However, there is little information about how this factor influences the diversity of terricolous lichens, ...
-
(2012)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 ...
-
(2006)It is generally assumed that larvae of benthic species are thoroughly mixed in the plankton and distributed randomly at settlement. Yet, it has also been hypothesized that a combination of larval gregarious behaviour coupled ...
-
(1977)The genetic information of Φx 174 genome (genes and intermediate segments) is analyzed in terms of its independent (D1 index) and dependent information (D2 and D3 Markovian indexes), as well as of its ability to generate ...
-
(Oxford University Press, 2020)Accurate taxonomic identification of alien species is crucial to detect new incursions, prevent or reduce the arrival of new invaders and implement management options such as biological control. Globally, the taxonomy of ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-12)The concerted action of extracellular signals such as BMP, Wnt, FGF, RA and Notch activate a genetic program required to transform a naive ectodermal cell into a neural crest cell. In this review we will analyze the ...
-
(Frontiers Media SA, 2017)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 ...
-
(Universidad Católica de Valparaíso, 2017)The study of species in their native geographic ranges is key to understanding how human activity has influenced spatial fragmentation or species homogenization. The Argentinian silverside Odontesthes bonariensis, of ...
-
(2009)The Chilean jack mackerel Trachurus murphyi, is a pelagic fish from the Carangidae family that is distributed in the South Pacific Ocean. Because this species constitutes an important economic resource across the South ...
-
(WFL PUBL, 2008-10)In this paper we evaluated the genetic diversity among apricot cultivars of different origins using SSR markers. Thirty-one apricot cultivars were evaluated, including one Japanese plum and one apricot x plum hybrid as ...
-
(1990)Controlled hand self- and cross-pollination and emasculations were performed on Ourisia poeppigii Benth. (Scrophulariaceae) from the Chilean Patagonia. Ourisia poeppigii is highly self-compatible and strongly autogamous. ...
-
(Public Library Science, 2018-06)One of the most relevant characteristics of the extant Southern Ocean fauna is its resiliency to survive glacial processes of the Quaternary. These climatic events produced catastrophic habitat reductions and forced some ...
