Avian haemosporidian infections in rufous-collared sparrows in an Andean dry forest: diversity and factors related to prevalence and parasitaemia
(Cambridge University PressParasitology, 2019)
Avian eggshell as a template for biomimetic synthesis of new materials
(2007)
Living organisms have evolved a vast diversity of mineralized structures through mechanisms that often are significantly different from those used by the materials engineer. These biomaterials often exhibit a fine‐scale ...
Acoustic monitoring shows invasive beavers Castor canadensis increase patch‐level avian diversity in Tierra del Fuego
(Wiley Blackwell Publishing, Inc, 2021-08)
The North American beaver Castor canadensis is an invasive species in the Tierra del Fuego Archipelago. Due to this biological invasion, Argentina and Chile signed an agreement to restore affected ecosystems by eradicating ...
Projected impacts of climate change on functional diversity of frugivorous birds along a tropical elevational gradient
(Nature Publishing Group, 2019-11)
Climate change forces many species to move their ranges to higher latitudes or elevations. Resulting immigration or emigration of species might lead to functional changes, e.g., in the trait distribution and composition ...
Avian diversity above the clouds: comparing elevational patterns in north and south temperate mountains
(2018)
Mountain ecosystems comprise 24% of the land-base of the Americas, and are critical components of the life-cycle for 35% of North American bird species. Globally, however, high elevation avian communities are poorly ...
Ocular Histomorphometry of Free-Living Common Kestrels (Falco tinnunculus)
(Assoc Avian Veterinarians, 2017-12-01)
We evaluated the histomorphometry of the eye structures (cornea, retina, choroid, and sclera) of 13 adult free-living common kestrels (Falco tinnunculus). Birds included in the study were euthanatized because of severe ...
Avian host composition, local speciation and dispersal drive the regional assembly of avian malaria parasites in South American birds
(Wiley Blackwell Publishing, Inc, 2019-05)
Identifying the ecological factors that shape parasite distributions remains a central goal in disease ecology. These factors include dispersal capability, environmental filters and geographic distance. Using 520 haemosporidian ...
Rolling Pampas agroecosystem: which landscape attributes are relevant for determining bird distributions
(Sociedad de Biología de Chile, 2014-04)
Background: Agricultural intensification is among the main factors affecting biodiversity. The Rolling Pampas of Argentina have undergone through a process of landscape transformation and agricultural intensification that ...
Avian assemblages in bamboo and non-bamboo habitats in a tropical rainforest
(2013-02-28)
Some species of bird are closely associated with bamboos (bamboo specialists) but community-wide studies comparing the avian assemblages in bamboo and non-bamboo habitats are lacking. Using point counts, we compared the ...
