Soil physicochemical factors as environmental filters for spontaneous plant colonization of abandoned tailing dumps
(Springer Verlag, 2017)
© 2017, Springer-Verlag Berlin Heidelberg. Abandoned tailing dumps (ATDs) offer an opportunity to identify the main physicochemical filters that determine colonization of vegetation in solid mine wastes. The current study ...
Phase characterization of LC (meth)acrylic monomers based on omega-hexyloxy- and omega-undecyloxy-salicylaldimine groups with different alkoxy tail substitutions
(TAYLOR & FRANCIS LTD, 2004-08)
The synthesis and phase characterization of three homologous series of liquid crystalline acrylic and methacrylic monomers, consisting of 21 new compounds are presented. They are based on omega-hexyloxy- and omega-undecy ...
The relationship of telomere length to baseline corticosterone levels in nestlings of an altricial passerine bird in natural populations
(Biomed Central, 2016)
Background: Environmental stressors increase the secretion of glucocorticoids that in turn can shorten telomeres via oxidative damage. Modification of telomere length, as a result of adversity faced early in life, can ...
Analysis of tailing pond contamination in Galicia using generalized linear spatial models
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-01-01)
We statistically analysed the chemical components present in waste water from mines in Galicia (NW Spain). These elements pose a risk to public health and the environment, most particularly in the event of a failure in the ...
Current breeding distributions and predicted range shifts under climate change in two subspecies of black-tailed godwits in Asia
(Wiley, 2022)
Habitat loss and shifts associated with climate change threaten global biodiversity, with impacts likely to be most pronounced at high latitudes. With the disappearance of the tundra breeding habitats, migratory shorebirds ...
Latitudinal gradients of haemosporidian parasites: prevalence, diversity and drivers of infection in the Thorn-tailed Rayadito (Aphrastura spinicauda)
(Elsevier, 2020)
Latitudinal gradients are well-suited systems that may be helpful explaining distribution of haemosporidian parasites and host susceptibility. We studied the prevalence, diversity and drivers of haemosporidian parasites ...
Environmental assessment of copper-gold-mercury mining in the Andacollo and Punitaqui districts, northern Chile
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-11)
The Coquimbo region has been one of the richest producers of Cu, Au and Hg in Chile, and some of the deposits have been mined almost continuously since the 16th century. To assess the potential environmental contamination ...
Maintenance of red-tail coral snake (Micrurus mipartitus) in captivity and evaluation of individual venom variability
(Universidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biología, 2016-09-01)
Red-tail coral snake (Micrurus mipartitus) is a long and thin bicolor coral snake widely distributed in Colombia and is the coral that causes the majority of accidents in the Andean region, so it is important to keep this ...
8-NH2-boldine, an antagonist of α1A and α1B adrenoceptors without affinity for the α1D subtype: Structural requirements for aporphines at α1- adrenoceptor subtypes
(2005)
Structure-activity analysis of 21 aporphine derivatives was performed by examining their affinities for cloned human α1A, α1B and α1D adrenoceptors (AR) using membranes prepared from rat-1 fibroblasts stably expressing ...
Assessing the impact of the invasive buff-tailed bumblebee (Bombus terrestris) on the pollination of the native Chilean herb Mimulus luteus
(Springer, 2013-06-18)
The arrival of exotic pollinators to new habitats may introduce new patterns of floral preference and foraging behavior that modify the structure of the resident plant-pollinator community. The aim of this paper is to ...
