Bryophyte diversity along an altitudinal gradient in Darién National Park, Panama [PDF]

open access: yes, 1992
A bryophyte inventory along an altitudinal gradient on Cerro Pirre (1200 m), Darién National Park, Panama, demonstrates that the different rain forest types along the gradient (inundatedlowland, hillside-lowland, submontane, montane elfin forest) have ...

Open forest successional stages and landscape heterogeneity promote wild bee diversity in temperate forests

open access: yesConservation Science and Practice, 2022
Recent studies have emphasized forests as crucial habitat for wild bees. In Europe, most forests are managed following the principles of close‐to‐nature silviculture, which combine timber production and nature conservation.

Tree regeneration responds more to shade casting by the overstorey and competition in the understorey than to abundance per se [PDF]

open access: yes, 2019
Manipulating the overstorey is the key tool for forest managers to steer natural regeneration. Opening up the canopy does not only create favourable light conditions for tree seedling growth, but also for (competitive) understorey species.
