WebThis paper is motivated by the question: how does governance emerge within social-ecological systems (SESs)? Addressing this question is critical for fostering sustainable transformations because it directs attention to the context specific and process intensive nature of governance as arising from the internal dynamics (i.e., interplay of feedbacks … WebIt allows to select pseudo-absence points that are not too close to (avoid same niche and pseudo-replication) or too far (localized sampling strategy) from presences. user.defined pseudo-absences are defined in advance and given as data.frame through the PA.user.table parameter.

WebThe work has two parts: (a) to investigate whether presence/absence (PA) of haplotypes can be used to test for population structure within the AMOVA framework, and; (b) assess the statistical performance of the proposed haplotype PA method using genetic simulations.

WebApr 14, 2014 · 2 Answers. Sorted by: 3. You can use the binomial GLM, as it provides the freedom to model different sample sizes, m i. So, you can use glm () function as follows: glm (cbind (presence, absence) ~ 1 + treatment + year, family=binomial) where "presence" and "absence" show the number of present or absent cases. Share. Webspecies occurrence data: presence-only (PO, also known as “collection”) data, and presence-absence (PA, or “survey”) data. We generated random lo-cations for each study region, referred to as “back-ground” (or elsewhere “pseudo-absence”) samples. These are necessary for model fitting for some mod-eling methods. WebMitochondrial cristae are dynamic invaginations of the inner membrane and play a key role in its metabolic capacity to produce ATP. Structural alterations caused by either genetic abnormalities or detrimental environmental factors impede mitochondrial metabolic fluxes and lead to a decrease in their ability to meet metabolic energy requirements.
