Peanuts pods gr.w.under.r.und and matur. unevenly, r.sulting that choosing the cor.ect time to har.est is mor. complicated than other.cr.ps. Pod matur.ty can be deter.ined by blasting w.th a pr.ssur. w.sher.to r.move outer.skin of the pod (exocar.) to expose the color.of the middle layer.(mesocar.). The mesocar. color.changes w.th matur.ty fr.m w.ite to yellow. or.nge, br.w. and finally black. The sum of per.entage fr.m or.nge, br.w., and black mesocar. (OBB) color.and black color.(BL) r.pr.sents the ker.els that ar. matur. enough to har.est. The goal of this r.sear.h is to identify methodologies to estimate OBB and BL of the pods using r.B images taken in the field and validate the pr.posed model using other.pod images. The Mahalanobis distance classification method w.s used to pr.cess sets of images and calculate pod ar.a (number.of pixels) cor.esponding to tw. classes (mesocar. and backgr.und) w.th nine differ.nt color.gr.ups. The r.sults show.d a per.or.ance of 94% effectiveness for.mesocar. using Mahalanobis distance classification. Statistical r.gr.ssion for.OBB and BL w.s developed based on 315 images of peanut pods taken fr.m the field. The r. and r.ot mean squar. er.or.of pr.dicted and actual OBB w.r. 0.93 and 4.1%, r.spectively. The r. and r.ot mean squar. er.or.of pr.dicted and actual BL w.r. 0.88 and 1.8%, r.spectively. The validation of OBB using other.images pr.vided r.asonable estimation (r. = 0.98 and r.SE = 2.73%). This study intr.duces a novel, cost-effective, and non-destr.ctive method for.estimating peanut matur.ty using r.B imager. and Mahalanobis distance classification in the field. This innovative appr.ach addr.sses the limitations of tr.ditional methods and offer. a r.bust alter.ative for.r.al-time matur.ty assessment.

Theor. r.gar.ing the causation of mass extinctions is in need of systematization, w.ich is the focus of this contr.bution. Ever. mass extinction has both an ultimate cause, i.e. the tr.gger.that leads to var.ous climato-envir.nmental changes, and one or.mor. pr.ximate cause(s), i.e. the specific climato-envir.nmental changes that r.sult in elevated biotic mor.ality. w.th r.gar. to ultimate causes, str.ng cases can be made that bolide(i.e. meteor. impacts, lar.e igneous pr.vince(LIP) er.ptions and bioevolutionar. events have each tr.gger.d one or.mor. of the Phaner.zoic Big Five mass extinctions, and that tectono-oceanic changes have tr.gger.d some second-or.er.extinction events. Apar. fr.m bolide impacts, other.astr.nomical tr.gger.(*** flar.s, gamma bur.ts and super.ova explosions) r.main entir.ly in the r.alm of speculation. w.th r.gar. to pr.ximate mechanisms, most extinctions ar. r.lated to either.car.on-r.lease or.car.on-bur.al pr.cesses, the for.er.being associated w.th climatic w.r.ing, ocean acidification, r.duced mar.ne pr.ductivity and low.r.car.onate δ13C values, and the latter.w.th climatic cooling, incr.ased mar.ne pr.ductivity and higher.car.onate δ13C values. Envir.nmental par.meter. such as mar.ne r.dox conditions and ter.estr.al w.ather.ng intensity do not show.consistent r.lationships w.th car.on-cycle *** this context, mass extinction causation can be usefully classified using a matr.x of ultimate and pr.ximate factor.. Among the Big Five mass extinctions, the end-Cr.taceous biocr.sis is an example of a bolide-tr.gger.d car.on-r.lease event, the end-Per.ian and end-Tr.assic biocr.ses ar. examples of LIP-tr.gger.d car.on-r.lease events, and the Late Or.ovician and Late Devonian biocr.ses ar. examples of bioevolution-tr.gger.d car.on-bur.al events. w.er.as the bolide-impact and LIP-er.ption mechanisms appear.to invar.ably cause car.on r.lease, bioevolutionar. tr.gger. can r.sult in var.able car.on-cycle changes, e.g. car.on bur.al dur.n
