Comparing taxon- and trait-environment relationships in stream communities
(2020-10-01)
Traits define how organisms interact with their surrounding environment and with other organisms. Thus, trait composition of biological communities is expected to change predictably along environmental gradients. Because ...
Bimodal trait distributions with large variances question the reliability of trait-based aggregate models
(Springer, 2016-12-01)
Functionally diverse communities can adjust their species composition to altered environmental conditions, which may influence food web dynamics. Trait-based aggregate models cope with this complexity by ignoring details ...
Leaf traits combinations may explain the occurrence of savanna herbaceous species along a gradient of tree encroachment
(2017-09-01)
In savanna environments, plants have specific leaf traits to deal with high irradiance. These traits allow plants to show high carbon assimilation capacity. However, under encroachment, reduced light availability may act ...
Dataset of occurrences and ecological traits of amphibians from Upper Paraguay River Basin, central South America
(Pensoft Publishers, 2020-09-02)
There are many gaps in our biodiversity knowledge, especially in highly diverse regions such as the Neotropics. Basic information on species occurrence and traits are scattered throughout different literature sources, which ...
Leaf litter traits drive community structure and functioning in a natural aquatic microcosm
(Wiley-Blackwell, 2018-04-01)
Leaf litter fuels secondary production in many aquatic ecosystems. Although the identity and species richness of leaf litter have been shown to influence ecosystem functioning and food-web composition, it has been challenging ...
Joint species movement modeling: how do traits influence movements?
(2019-04-01)
Joint species distribution modeling has enabled researchers to move from species-level to community-level analyses, leading to statistically more efficient and ecologically more informative use of data. Here, we propose ...
Do regeneration traits vary according to vegetation structure? A case study for savannas
(Wiley-Blackwell, 2020-09-13)
Aim Regeneration traits are crucial for understanding patterns and processes in plant communities. However, regeneration traits are not reported much in community ecology, preventing a better assessment of trait-based ...
Optimal strategies for sampling functional traits in species-rich forests
(Wiley, 2015-03)
1. Functional traits provide insight into a variety of ecological questions, yet theoptimal sampling method to estimate the community-level distribution of plantfunctional trait values remains a subject of debate, especially ...
Morphometric traits as drivers for module structures and species specialization: a study about the hermit crab–gastropod networks from three different regions on the Brazilian coast
(2022-01-01)
The relationship between hermit crabs (Paguroidea) and gastropod shells has attracted the attention of researchers toward a network approach. These networks seem to present recurrent patterns that are often modular, i.e., ...
Effects of plant species traits on ecosystem processes: experiments in the Patagonian steppe
(Ecological Society Of America, 2012-02)
Several experiments have shown that aboveground net primary productivity increases with plant species richness. The main mechanism proposed to explain this relationship is niche complementarity, which is determined by ...
