Renal tumor s.rgery places.patients.at increas.d ris. for chronic kidney dis.as.(CKD). Accurate quantification of kidney function changes.before and after s.rgery is.es.ential to determine the magnitude of decline attributable to an index procedure. Current literature, however, highlights.heterogeneity and incons.s.encies.in meas.rement techniques.thereby contributing to ambiguity amongs. s.udies. Further efforts.are neces.ary to s.andardize reporting of kidney function outcomes.related to renal s.rgery.

Tree s.ecies.in coas.al fores.s.may exhibit s.ecialization or plas.icity in coping with drought through changes.in their s.omatal morphology or activity, allowing for a balance between gas.exchange and water los. in a periodically s.res.ful environment. To examine thes. res.ons.s. we s.ught to ans.er two primary res.arch ques.ions. a) how is.variation in B. s.maruba’s.s.omatal traits.partitioned acros. hierarchical levels. i.e., s.te, tree, and leaf;and b) is.variation in s.omatal traits.an integrated res.ons. to phys.ological s.res. expres.ed acros. the habitat gradient of Florida Keys.fores.s. At eight s.tes.dis.ributed throughout the Keys. five leaves.were collected from three mature trees.for s.omatal analys.s. Leaf carbon s.able is.tope ratio (δ13C) was.determined to infer the changes.in water us. efficiency caus.d by phys.ological s.res. experienced by each tree. The res.lts.s.owed that s.bs.antial proportions.of the total variance in three traits.(s.omatal dens.ty, s.omatal s.ze, and δ13C) were obs.rved at all levels. s.gges.ing that proces.es.operating at each s.ale are important in determining trait values. A s.gnificant negative correlation between s.omatal dens.ty and s.ze acros. s.ales.was.obs.rved. Path model analys.s.s.owed that environmental variables. dis.ance to ground water and ground water s.linity, affect leaf δ13C indirectly, via its.effects.on s.omatal traits. not directly to leaf δ13C. Therefore, the combination of s.all and dens.ly dis.ributed s.omata s.ems.to repres.nt a s.rategy that allows.B. s.maruba to cons.rve water under conditions.of phys.ological drought induced by either higher ground water s.linity or flooding s.res. at very low elevation.
