Chromosome polymorphisms affecting recombination and exophenotypic traits in Leptysma argentina (Orthoptera): a populational
Penha (2004) studied the influence of root suckering on populational
characteristics of tree species in another Seasonal Semideciduous Forest fragment in the State of Sao Paulo and observed young clones for Centrolobium tomentosum at fire-disturbed forest areas, whereas no clone was found at the non fire-disturbed forest areas.
units from a single year-class, with particular spawning seasons and areas, have been recognized on the Argentinean shelf and slope.
Additional research would be necessary to confirm the ecology and populational
status of jaguarundis in the habitat types prevailing in the Kaa-Iya National Park.
and celular density were registered daily.
Psecas chapoda spends its entire reproductive cycle: courtship, mating, ovisac formation and populational
recruitment of the young spiders on this plant (Rossa-Feres et al.
Objectives Mortality is a definition of strictly populational
nature, different from the concepts of death and decease which reflect the loss of an individual biological life.
Application of results from parasitological investigations in redfish (Sebastes mentella Travin) populational
Yielding stability in unpredictably variable environments can be due to individual and/or populational
buffering (Allard and Bradshaw, 1964).
The dominant epiphytes, and their natural cover proportions (digitized from stop-action quadrats of the macrovideo transects, see populational
survey below), were the macrophytes Amphiroa fragilissima (mean [+ or -] 1 SE = 28 [+ or -] 5%), Dictyota pulchella (27 [+ or -] 3%), Spyridia complanata (19 [+ or -] 4%), Laurencia intricata (15 [+ or -] 4%) and Acanthophora spicifera (11 [+ or -] 3%).
First, why is a populational
analysis of genetic correlations necessary?
Daniel Callahan's call for the resurrection of nature in moral life and reflection is timely and urgent, given the new assaults - technological, economic, and populational
- on our human selves and communities and the rest of nature.
