Natal dispersal in monogamous owl monkeys (Aotus azarai) of the Argentinean Chaco
(Brill Academic Publishers, 2009-01)
This study offers a detailed description of natal dispersal patterns in owl monkeys (Aotus azarai) and evaluates the extent and characteristics of sex-biased dispersal in this monogamous mammal. Owl monkeys are small, ...
Biological and environmental effects on fine-scale seed dispersal of an invasive tree in a secondary subtropical forest
(Springer, 2018-02)
Dispersal abilities of invading species emerge from the interaction between the species and some features of the target community. Ligustrum lucidum is a tree species invading different ecosystems. Major spatial patterns ...
Crop size is more important than neighborhood fruit availability for fruit removal of Eugenia uniflora (Myrtaceae) by bird seed dispersers
(Springer, 2011-05)
For a plant with bird-dispersed seeds, the effectiveness of seed dispersal can change with fruit availability at scales ranging from individual plants to neighborhoods, and the scale at which frugivory patterns emerge may ...
Extension of a classic theory of the low frequency dielectric dispersion of colloidal suspensions to the high frequency domain
(American Chemical Society, 2010-10)
The classic Shilov-Dukhin theory of the low frequency dielectric dispersion of colloidal suspensions in binary electrolyte solutions [Shilov, V. N.; Dukhin, S. S., Colloid J. 1970, 32, 245.; Dukhin, S. S.; Shilov, V. N. ...
Active dispersal in Triatoma infestans (Klug, 1834) (Hemiptera: Reduviidae: Triatominae): Effects of nutritional status, the presence of a food source and the toxicological phenotype
(Elsevier Science, 2020-01)
In Argentina, the main vector of Chagas disease is Triatoma infestans (Klug, 1834). In recent years, the presence of T. infestans was reported in human dwelling after spraying with pyrethroids in several locations in ...
Seed dispersal effectiveness by frugivorous birds: Identifying functional equivalent species in bird assemblages
(Science Reviews 2000 Ltd, 2019-08)
Seed dispersal by birds is a pivotal ecosystem function worldwide; yet, the rapid and ongoing global biodiversity loss poses a major threat to this essential ecosystem service. Seed dispersal effectiveness (SDE) is a key ...
Maximum-likelihood sequence estimation in dispersive optical channels
(Institute of Electrical and Electronics Engineers, 2005-02)
This paper discusses the investigation of maximum-likelihood sequence estimation (MLSE) receivers operating on intensity-modulated direct-detection optical channels. The study focuses on long-haul or metro links spanning ...
Generalist birds promote tropical forest regeneration and increase plant diversity via rare-biased seed dispersal
(Ecological Society of America, 2016-07)
Regenerated forests now compose over half of the world's tropical forest cover and are increasingly important as providers of ecosystem services, freshwater, and biodiversity conservation. Much of the value and functionality ...
Non-redundancy in seed dispersal and germination by native and introduced frugivorous birds: implications of invasive bird impact on native plant communities
(Springer, 2018-12)
Seed dispersal by vertebrate animals is important for the establishment of many fleshy-fruited plant species. Different frugivorous species can provide different seed dispersal services according to their specific dietary ...
Effect of nutritional state and dispersal on the reproductive efficiency in Triatoma infestans (Klug, 1834) (Hemiptera: Reduviidae: Triatominae) susceptible and resistant to deltamethrin
(Elsevier Science, 2019-03)
The dispersal of insects is determinant in the colonization of new areas and the propagation of insecticide resistance. Nutritional status and reproductive characteristics determine the colonization capacity after the ...
