A Unifying Concept for Growth Trends of Trees and Forests – The “Potential Natural Forest”

open access: yesFrontiers in Forests and Global Change, 2020
Changes in the environment will alter the growth rate of trees and forests. Different disciplines assess such growth rates differently, for example, with tree-ring width data, forest inventories or with carbon-flux data from eddy covariance towers.

The Pongola Bush: Tree diversity assessment in a KwaZulu-Natal forest patch

open access: yesKoedoe: African Protected Area Conservation and Science, 2022
The Pongola Bush Nature Reserve lies in a narrow band along the escarpment between Mpumalanga and KwaZulu-Natal (KZN). Although referred to as ‘bush’, this vegetation type may be considered to fit into the intersection of two types of scarp forest: the ...

Dual stable isotope abundances unravel trophic position of estuarine nematodes [PDF]

open access: yes, 2005
The role and quantitative importance of free-living nematodes in marine and estuarine soft sediments remain enigmatic for lack of empirical evidence on the feeding habits and trophic position of most nematode species.

Rates of sustainable forest harvest depend on rotation length and weathering of soil minerals [PDF]

open access: yes, 2014
Removals of forest biomass in the northeastern US may intensify over the coming decades due to increased demand for renewable energy. For forests to regenerate successfully following intensified harvests, the nutrients removed from the ecosystem in the ...

Kochia (Kochia scoparia) and Wild Oat (Avena fatua) Intraspecific and Interspecific Interference

open access: yesAgronomy, 2020
Kochia (Kochia scoparia) and wild oat (Avena fatua) are highly problematic western Canadian weeds. Wild oat is widely distributed and has been a long-standing agricultural pest across Manitoba, Saskatchewan, and Alberta. Kochia populations are patchy and

The Relationship between Burrow Opening Dimensions and Biomass of Intertidal Macroinvertebrates by Feeding Mode (Surface Deposit Feeders vs. Suspension Feeders)

open access: yesAnimals, 2022
Biomass and abundance are fundamental parameters in ecology, conservation biology, and environmental impact assessment. Distinguishing features, such as burrow openings and feeding pellets, made by different intertidal macroinvertebrate species on the ...

Changes in microphytobenthos fluorescence over a tidal cycle: implications for sampling designs [PDF]

open access: yes, 2013
Intertidal microphytobenthos (MPB) are important primary producers and provide food for herbivores in soft sediments and on rocky shores. Methods of measuring MPB biomass that do not depend on the time of collection relative to the time of day or tidal ...

The benthic fauna: ecology, biomass and communities

open access: yes, 1983
Benthos consists of all those aquatic organisms which are associated in some way with the bottom sediments. We shall, therefore, consider here only the organisms and communities inhabiting the lake sediments, reserving a study of the periphyton found on higher aquatic plants for a further chapter.

Non-native populations of an invasive tree outperform their native conspecifics [PDF]

open access: yes, 2015
Introduced plants often face new environmental conditions in their non-native ranges. To become invasive, they need to overcome several biotic and abiotic filters that may trigger adaptive changes in life-history traits, like postgermination processes ...
