Forest soil carbon stock decreases for up to 30 years, with up to 23%, following clear-cutting, according to a major study from the Nordic countries and Canada.

En ny litteraturstudie gir oversikt over hvordan flatehogst påvirker arter som lever i boreale skogøkosystemer. "Vi ser at mange av samfunnene av sopp, insekter, lav og moser ikke har klart å komme seg igjen selv 50 til 80 år etter flatehogst", sier Lisa Fagerli Lunde.

Species interactions can have cascading effects on metacommunity dynamics. Nenzén et al. show how temporal presence-absence data can be combined with experimental data to identify which species impact the colonization-extinction dynamics of others. esajournals.onlinelibrary.wiley.com/doi/full/10....

Nei, ikke motsatt! De to artiklene ser på ulike aspekter av karbondynamikk. Madsen mfl. ser på flukser i form av respirasjon (CO2) og strøtilførsel i moden skog mens Johannesson mfl. ser på størrelsen av C-lagre under bakken i skoger som har blitt flatehogd opptil 53 år før måling av karbonlagre.

Madsen et al. show that in mature boreal forests, previously clear-cut stands had higher soil respiration rates and greater tree litterfall but smaller understorey litterfall C inputs than near-natural stands. The C flux balances were similar in the stand types.
