A unified framework for partitioning the drivers of stability of ecological communitiesNARA Subscribed
Aim Identifying the drivers of ecological stability is critical for ensuring the maintenance of ecosystem functioning and services, particularly in a changing world. Different ecological mechanisms by which biological communities stabilize ecosystem functions (i.e. “stabilizing effects”) have been proposed, yet with various theoretical expectations and debated conclusions. Here we propose a unified framework that aims at recon...
Responding to the UN sustainability goals in transdisciplinary partnership through network action learningNARA Subscribed
The global water crisis, an enormous concern according to the World Economic Forum, poses a significant challenge to long-term sustainability, exacerbated by the high energy demand associated with water supply and treatment. As the renewable energy sector grows, the need for green technologies to support the water-energy nexus becomes evident. However, mere technological advancements are insufficient to address complex water-r...
The functional structure of plant communities drives soil functioning via changes in soil abiotic propertiesNARA Subscribed
While biodiversity is expected to enhance multiple ecosystem functions (EFs), the different roles of multiple biodiversity dimensions remain difficult to disentangle without carefully designed experiments. We sowed plant communities with independent levels of functional (FD) and phylogenetic diversities (PD), combined with different levels of fertilization, to investigate their direct and indirect roles on multiple EFs, includ...
L-lactic and 2-ketoglutaric Acids, Odors from Human Skin, Govern Attraction and Landing in Host-Seeking Female Aedes aegypti MosquitoesNARA Subscribed
Aedes aegypti , presented with a source of L-lactic and 2-ketoglutaric acid in a wind-tunnel bioassay, takeoff, fly upwind, and land on the odorant substrate at rates comparable to those exhibited by mosquitoes presented with a skin-odor stimulus. Addition of carbon dioxide decreased takeoff latency but was not required to elicit upwind flight nor landings. Ketoglutaric acid, a recently identified component of human skin odor,...
Trait probability density ( TPD ): measuring functional diversity across scales based on TPD with RNARA Subscribed
Functional diversity ( FD ) has the potential to address many ecological questions, from impacts of global change on biodiversity to ecological restoration. There are several methods estimating the different components of FD . However, most of these methods can only be computed at limited spatial scales and cannot account for intraspecific trait variability ( ITV ), despite its significant contribution to FD . Trait probabilit...
Functional differences stabilize beetle communities by weakening interspecific temporal synchronyNARA Subscribed
The temporal stability of communities is essential for the maintenance of ecosystem functioning across trophic levels. The stabilizing effect of biodiversity is, among other factors, modulated by the level of synchrony in population fluctuations among the species in the community. What drives community synchrony, however, remains largely unclear. Community synchrony can be affected by external drivers such as disturbances, but...
Stabilizing effects in temporal fluctuations: management, traits, and species richness in high‐diversity communitiesNARA Subscribed
The loss of biodiversity is thought to have adverse effects on multiple ecosystem functions, including the decline of community stability. Decreased diversity reduces the strength of the portfolio effect, a mechanism stabilizing community temporal fluctuations. Community stability is also expected to decrease with greater variability in individual species populations and with synchrony of their fluctuations. In semi‐natural me...
Applying the dark diversity concept to nature conservationNARA Subscribed
Linking diversity to biological processes is central for developing informed and effective conservation decisions. Unfortunately, observable patterns provide only a proportion of the information necessary for fully understanding the mechanisms and processes acting on a particular population or community. We suggest conservation managers use the often overlooked information relative to species absences and pay particular attent...
Understanding the processes regulating population temporal stability is important to infer species coexistence and ecosystem stability patterns. It has been hypothesized that population temporal stability could be driven by functional trade‐offs in resource acquisition and growth rate strategies. We tested this hypothesis by analyzing a 13‐year data set from a mown grassland community in a factorial experiment with fertilizati...
Functional trait differences among species are increasingly used to infer the effects of biotic and abiotic processes on species coexistence. Commonly, the trait diversity observed within communities is compared to patterns simulated in randomly generated communities based on sampling within a region. The resulting patterns of trait convergence and divergence are assumed to reveal abiotic and biotic processes, respectively. Ho...
