Spontaneous mutation accumulation in multiple strains of the green alga, Chlamydomonas reinhardtii [PDF]

, 2014
Estimates of mutational parameters, such as the average fitness effect of a new mutation and the rate at which new genetic variation for fitness is created by mutation, are important for the understanding of many biological processes. However, the causes

Yessotoxins in Mollusks of the Galician Coast from 2014 to 2022: Variability, Biotransformation, and Resistance to Alkaline Hydrolysis

Toxins, 2023
The presence of yessotoxins (YTXs) was analyzed in 10,757 samples of Galician bivalves from 2014 to 2022. Only YTX and 45-OH YTX were found. YTX was detected in 31% of the samples, while 45-OH YTX was found in 11.6% of them.

Divergent drivers of leaf trait variation within species, among species, and among functional groups. [PDF]

, 2018
Understanding variation in leaf functional traits-including rates of photosynthesis and respiration and concentrations of nitrogen and phosphorus-is a fundamental challenge in plant ecophysiology. When expressed per unit leaf area, these traits typically

Differential spatial distribution of miR165/6 determines variability in plant root anatomy [PDF]

, 2017
A clear example of interspecific variation is the number of root cortical layers in plants. The genetic mechanisms underlying this variability are poorly understood, partly due to the lack of a convenient model.

A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]

, 2007
Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.

Relationships between Phyllosphere Bacterial Communities and Leaf Functional Traits in a Temperate Forest

Plants, 2023
As a vital component of biodiversity, phyllosphere bacteria in forest canopy play a critical role in maintaining plant health and influencing the global biogeochemical cycle.

Interspecific variation in the elemental and stable isotope content of seagrasses in South Florida [PDF]

, 2009
The elemental (C, N, and P) and isotope (δ13C, δ15N) content of leaves of the seagrasses Thalassia testudinum, Halodule wrightii, and Syringodium filiforme were measured across a 10 000 km2 survey of the seagrass communities of South Florida, USA, in ...

Interspecific interactions, population variation, and environmental forcing in the context of the community

Ecosphere, 2016
We evaluated the contribution of interspecific interactions, intraspecific processes, and environmental forcing to variation in speciessa' abundance in a habitat undergoing rapid successional change. We applied a Bayesian hierarchical approach to a 29‐yr

How self-regulation, the storage effect and their interaction contribute to coexistence in stochastic and seasonal environments [PDF]

, 2019
Explaining coexistence in species-rich communities of primary producers remains a challenge for ecologists because of their likely competition for shared resources.

Qualitative geographical variation in interspecific interactions

Ecography, 2004
We explore geographical variation in the density relationship between potential competitor forest bird groups, resident Parus spp. and migrant Fringilla spp., across Europe using published bird census results.
