Population responses of pest birds across a forest cover gradient in the Chaco ecosystem
(Elsevier Science, 2021-07)
Industrial agriculture can trigger an increase in abundance of some bird species, promoting the emergence of pests, causing damage to crops and economic loss for farmers. Even though there are different strategies to control ...
The seasonal role of field characteristics on seed-eating bird abundances in agricultural landscapes
(Oxford University Press, 2017-06)
In temperate agroecosystems, avian responses in abundance and distribution to landscape attributes may be exacerbated by the coupling of natural seasons and farming practices. We assessed the seasonal roles of field type, ...
Interplay between the morphometry of the lungs and the mode of locomotion in birds and mammals
(2007)
We studied the lung diffusion parameters of two species of birds and two species of mammals to explore how structural and functional features may be paralleled by differences in life style or phylogenetic origin. We used ...
Regional anesthesia to ameliorate postoperative analgesia outcomes in pediatric surgical patients: an updated systematic review of randomized controlled trials
(Dove Medical Press Ltd, 2018-01-01)
Regional anesthesia is becoming increasingly popular among anesthesiologists in the management of postoperative analgesia following pediatric surgery. The main objective of this review was to systematically evaluate the ...
Hypercarnivorous apex predator could provide ecosystem services by dispersing seeds
(Nature Publishing Group, 2016-01)
Large ?hypercarnivorous? felids are recognized for their role as apex predators and hence as key elements in food webs and ecosystem functioning through competition and depredation. Here we show that cougars (Puma concolor), ...
Eritroleucometria, bioquímica plasmática e sérica e histopatologia de pombas (Zenaida auriculata) submetidas à intoxicação experimental com metamidofós: validade da espécie como indicador de qualidade ambiental
(Universidade Estadual Paulista (Unesp), 2006-06-23)
As aves, especialmente as sedentárias, têm sido utilizadas para a avaliação da qualidade do meio ambiente onde estão fixadas, mostrando-se valiosos bioindicadores. A pomba amargosa, Zenaida auriculata, pode ter uma promissora ...

¿Eligen las palomas y cotorras los lotes de soja (Glycine max) enemergencia? Un caso de estudio en agroecosistemas de Entre Ríos, Argentina = Do pigeons and parakeets choose soybean (Glycine max) crops during the emergence? A case studyon agroecosystems in Entre Ríos, Argentina
(Instituto de Biología, Universidad Nacional Autónoma de México, 2016-12)
Las palomas y cotorras pueden resultar perjudiciales para cultivos anuales en algunas regiones de Sudamérica. En este estudio analizamospatrones de uso de hábitat de las palomas torcaza (Zenaida auriculata), manchada ...
The prevalence and molecular characterisation of blood parasites infecting the vulnerable Tamarugo Conebill (Conirostrum tamarugense) and other birds in the Pampa del Tamarugal, Chile
(2016)
Blood parasites exert significant selective pressure, which can alter population dynamics, and the introduction of new parasite lineages in a region could lead to the extinction of endemic avian species that have not ...
