Conspecific leaf litter and root competition inhibits shrub emergence in the Patagonian steppe
(Springer, 2019-09)
A critical stage in the establishment of new individuals is seedling emergence and litter is a main factor affecting this stage. Recent research found that adults of Chuquiraga avellanedae are overdispersed. Among several ...
A robust conditional maximum likelihood estimator for generalized linear models with a dispersion parameter
(Springer, 2019-03-12)
Highly robust and efficient estimators for generalized linear models with a dispersion parameter are proposed. The estimators are based on three steps. In the first step, the maximum rank correlation estimator is used to ...
Estimation of effective population size using bivariate discrete distributions for modeling family size in beef cattle
(Elsevier Science, 2008-08)
Pedigree records of 72,808 animals (45,668 females and 27,140 males) from the genetic evaluation program of the Argentine Brangus Association were used to estimate effective number of founders (Nf), effective number of ...
Phylogenetic structure of geographical co-occurrence among New World Triatominae species, vectors of Chagas disease
(Wiley Blackwell Publishing, Inc, 2020-06)
The tropical niche conservatism (TNC) hypothesis is one of the most prominent evolutionary hypotheses that has been supported as an explanation for the diversity gradients of several animal taxa, mainly vertebrates. However, ...
Helminth communities in the burrowing toad, Rhinella fernandezae, from Northeastern Argentina
(Versita, 2013-12)
The main goals of this study were to determine the richness and diversity of helminth parasites of Rhinella fernandezae at the component and infracommunity levels and determine the ecological implications of different ...
Patrones de depósito de polen sobre el cuerpo de los polinizadores en comunidades esfingófilas de Argentina subtropical
(Instituto de Botánica Darwinion, 2014-09)
Patrones de depósito de polen sobre el cuerpo de los polinizadores en comunidades esfingófilas de Argentina Subtropical. Las especies de plantas que coexisten y comparten agentes polinizadores pueden experimentar competencia ...
Spatial distribution of medusa Cunina octonaria and frequency of parasitic association with Liriope tetraphylla (Cnidaria: Hydrozoa: Trachylina) in temperate Southwestern Atlantic waters
(Academia Sinica, 2020-11)
This study examined the spatial distribution of the medusae phase of Cunina octonaria (Narcomedusae) in temperate Southwestern Atlantic waters using a total of 3,288 zooplankton lots collected along the Uruguayan and ...
Opposing community assembly patterns for dominant and non-dominant plant species in herbaceous ecosystems globally
(Wiley Ecology and evolution, 2021-11-22)
Biotic and abiotic factors interact with dominant plants—the locally most frequent or with the largest coverage—and nondominant plants differently, partially because dominant plants modify the environment where nondominant ...
Eliminación de huevos de los pequeños estróngilos en la materia fecal de los equinos y su importancia práctica en la posibilidad de tratamientos selectivosFecal shedding of equine small strongyle eggs and its practical importance for selective treatment
(Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2020-04)
Los pequeños estróngilos son los parásitos de mayor prevalencia e importancia en los equinos de todo el mundo, y el desarrollo generalizado de la resistencia de estos nematodos a los antihelmínticos está impulsando la ...
Opposing community assembly patterns for dominant and jonnondominant plant species in herbaceous ecosystems globally
(John Wiley & Sons Inc., 2021-12)
Biotic and abiotic factors interact with dominant plants—the locally most frequent or with the largest coverage—and nondominant plants differently, partially because dominant plants modify the environment where nondominant ...
