Ecological contingency in species shifts: downslope shifts of woody species under warming climate and land-use change

open access: yesEnvironmental Research Letters, 2019
A predicted impact of a warming climate is an upslope shift of montane plant species. These upslope shifts may be amplified by land-use changes or attenuated by forest recoveries at low elevations where historical disturbances were ceased allowing for ...

The use of the arithmetic mean of diameters in the estimation of basal area: - III biases in the estimation of remaining basal area

open access: yes, 1971
São determinados vícios no cálculo da área basal remanescente a partir da média aritmética dos diâmetros, em comparação com o método de cálculo a partir da soma dos quadrados dos diâmetros. Os estudos são conduzidos tanto teòricamente como em amostras geradas em computador, com confirmações com dados coletados em desbastes de povoamentos florestais. Os
