DistUrbio antrOpico crOnico em fragmentos
de mata seca da Caatinga
Chronic anthropogenic disturbance on Caatinga dry forest fragments

Matsumoto
Journal of Applied Ecolog
57, pp. 2064–2074, 2020
Uma breve introducao...
Praticas de conservaco e gestao mais
eficazes
Caatinga potencialmente alterada
Objetivos
Intensidade da perturbacao potencial varia:
Distancia ate a borda do

Material e metodos
Indice cronico de Disturbio antropogenico (CDI)
Dimensao da pesquisa

Chronic anthropogenic disturbance on Caatinga dry forest fragments
Journal of Applied Ecology, Volume: 57, Issue: 10, Pages: 2064-2074, First published: 05 July 2020, DOI: (10.1111/1365-2664.13686)
Chronic anthropogenic disturbance of
Caatinga dry forest fragments. (a) Chronic
anthropogenic disturbance index (CDI) at the
pixel scale, (b) mean CDI of all Caatinga
fragments and (c) coefficient of variation of
CDI for all Caatinga fragments, as a measure
of fragment heterogeneity

Edge effect of chronic anthropogenic disturbance
index and its five vectors in Caatinga fragments. (a)
Chronic anthropogenic disturbance, (b) human
population, (c) infrastructure, (d) grazing, (e) wood
extraction and (f) fire. All relationships were built
based on 6,820 points from a stratified random
sampling. Lines represent quantile asymptotic
regressions (a–d, tau = 0.5) and linear regressions
(e, tau = 0.5, f, tau = 0.9,
Resultados
Fortes efeitos de borda foram reconhecidos
para o CDI e seus cinco vetores
Resultados
Resultados indicam que estado atual da Caatinga e
uma superestimativa grave do estado de conservação;
maior parte da vegetacao remanescente sofre de
disturbios antropicos cronicos.
discussao
Ao reconhecer a qualidade do habitat, pode-se
prever que os fragmentos variam amplamente em seu
estado de conservacao.
discussao
Assim, ao criar uma classificacao continua de
disturbio antropico cronico, entendemos melhor a
heterogeneidade dentro e entre fragmentos de
Caatinga e padroes regionais de modificacao da
paisagem
discussao
Grandes cidades, capital mais rica e
densamente povoada da Caatinga, sao fortes
atratores de disturbios cronicos na regiao
Norte, com efeitos claros sobre o
territorio circundante.
Consideracoes e conclusoes

naturais erodidos
remanescentes provavelmente
sofrem com disturbios
antropicos cronicos.
