Functional Rarity: The Ecology of Outliers [PDF]

Trends in Ecology & Evolution, 2017
Rarity has been a central topic for conservation and evolutionary biologists aiming to determine the species characteristics that cause extinction risk. More recently, beyond the rarity of species, the rarity of functions or functional traits, called functional rarity, has gained momentum in helping to understand the impact of biodiversity decline on ...

Genome size variation and polyploidy incidence in the alpine flora from Spain

Anales del Jardín Botánico de Madrid, 2013
The interest to study genome evolution, in particular genome size variation and polyploid incidence, has increased in recent years. Still, only a few studies have been focused at a community level.

Bootstrapping outperforms community‐weighted approaches for estimating the shapes of phenotypic distributions

Methods in Ecology and Evolution, 2023
Estimating phenotypic distributions of populations and communities is central to many questions in ecology and evolution. These distributions can be characterized by their moments (mean, variance, skewness and kurtosis) or diversity metrics (e.g ...

Height and crown allometries and their relationship with functional traits: An example from a subtropical wet forest

Ecology and Evolution, 2023
Forest tree communities are largely structured by interactions between phenotypes and their environments. Functional traits have been popularized as providing key insights into plant functional tradeoffs.

Bacterial and Archaeal Structural Diversity in Several Biodeterioration Patterns on the Limestone Walls of the Old Cathedral of Coimbra

Microorganisms, 2021
The “University of Coimbra-Alta and Sofia” area was awarded the UNESCO World Heritage Site distinction in 2013. The Old Cathedral of Coimbra, a 12th-century limestone monument located in this area, has been significantly impacted during the last 800 ...

Unintentional seed dispersal via container-grown garden plants: Seed density and composition vary among exporter countries [PDF]

NeoBiota
The global ornamental plant trade is well-known as an important source of non-native plants, but the unintentional dispersal of seeds as contaminants of this trade is rarely considered and largely understudied.

Functional Molecular Ecological Networks [PDF]

mBio, 2010
ABSTRACT Biodiversity and its responses to environmental changes are central issues in ecology and for society. Almost all microbial biodiversity research focuses on “species” richness and abundance but not on their interactions. Although a network approach is powerful in describing ecological interactions among species, defining

Asexual reproduction of a few genotypes favored the invasion of the cereal aphid Rhopalosiphum padi in Chile [PDF]

PeerJ, 2019
Background Aphids (Hemiptera: Aphididae) are insects with one of the highest potentials for invasion. Several aphid species are present globally due to introduction events; they represent important pests of agroecosystems.

Multilayer networks reveal the spatial structure of seed-dispersal interactions across the Great Rift landscapes

Nature Communications, 2018
Species interaction networks have been usually delimited by perceived habitat borders. Here, seed-dispersal is analyzed as a regional multilayer network of interconnected habitats, highlighting the key role of versatile dispersers for the functional ...

Author Correction: Multilayer networks reveal the spatial structure of seed-dispersal interactions across the Great Rift landscapes

Nature Communications, 2018
The original version of this Article contained Figshare links in the Code availability statement that were not functional. The correct Figshare links to MATLAB scripts and R code used in this study are https://doi.org/10.6084/m9.figshare.4955651 and ...
