Abstract

Dead organic matter represents an essential reservoir of carbon, especially that allocated in standing dead
trees, coarse woody debris, and fine litter, playing a pivotal role in nutrient cycling and habitat provisioning.
However, necromass is frequently disregarded in forest assessments. Here, we aimed to perform the first
assessment of multiple necromass compartments in the Atlantic Forest of Northeast Brazil, providing a basis
for future integrative studies related to necromass in this region. We registered 17 standing dead trees in 0.5
hectare and 239 logs of coarse woody debris. Necromass had 3.9 Mg.ha-1 of standing dead trees, 54.24 Mg.ha-1
of coarse woody debris and 7.2 Mg.ha-1 of litter. We indicate that standing dead trees and coarse debris were
mostly in the intermediate and final stages of decomposition. Leaves were the dominant component of litter,
and drier months had more litterfall. Finally, we highlight that assessing standing dead trees and coarse woody
debris adds 25.6% on top of aboveground tree mass, improving information about organic matter storage
in rainforest ecosystems. Our findings emphasize that the necromass compartment must be considered in
forest assessments, also including small pieces of coarse woody debris, which could inform better practices
of forest management.

Key words: decay stage, DOM, line-intercept method, litter, urban forest.




Resumo

A mat&#xE9;ria org&#xE2;nica morta representa uma reserva essencial de carbono, especialmente aquela alocada na
necromassa arb&#xF3;rea (&#xE1;rvores mortas em p&#xE9;, serapilheira grossa e serapilheira fina), desempenhando um papel
fundamental na ciclagem de nutrientes e na provis&#xE3;o de habitat. Entretanto, a necromassa &#xE9; frequentemente
desconsiderada em invent&#xE1;rios florestais. Aqui, objetivamos realizar o primeiro levantamento de v&#xE1;rios
componentes da necromassa na Floresta Atl&#xE2;ntica do Nordeste do Brasil, fornecendo uma base para futuros
estudos integrativos relacionados &#xE0; necromassa nessa regi&#xE3;o. Registramos 17 &#xE1;rvores mortas em p&#xE9; em 0,5
hectare e 239 tocos de serapilheira grossa. As estimativas de necromassa foram 3,9 Mg.ha-1 para &#xE1;rvores
mortas em p&#xE9;, 54,24 Mg.ha-1 para serapilheira grossa e 7,2 Mg.ha-1 para serapilheira fina. Indicamos que a
maior parte das &#xE1;rvores mortas em p&#xE9; e serapilheira grossa estavam em est&#xE1;gios intermedi&#xE1;rios e finais de
decomposi&#xE7;&#xE3;o. A fra&#xE7;&#xE3;o folhas foi o componente dominante da serapilheira fina e meses secos tiveram maior
queda deste componente. Finalmente, destacamos que inventariar &#xE1;rvores mortas em p&#xE9; e serapilheira grossa
representa um incremento de 25,6% na biomassa arb&#xF3;rea acima do solo, aprimorando as informa&#xE7;&#xF5;es sobre
estoques de mat&#xE9;ria org&#xE2;nica em florestas &#xFA;midas. Destacamos que o compartimento de necromassa deve
ser considerado em invent&#xE1;rios florestais, tamb&#xE9;m incluindo peda&#xE7;os pequenos de serapilheira grossa, o que
pode informar melhores pr&#xE1;ticas de manejo florestal.
