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.

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 ...

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.

Extracellular Enzymatic Activities of Oceanic Pelagic Fungal Strains and the Influence of Temperature

Journal of Fungi, 2022
Although terrestrial and aquatic fungi are well-known decomposers of organic matter, the role of marine fungi remains largely unknown. Recent studies based on omics suggest that marine fungi potentially play a major role in elemental cycles.

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 ...

Shifts in Ectomycorrhizal Fungal Communities and Exploration Types Relate to the Environment and Fine-Root Traits Across Interior Douglas-Fir Forests of Western Canada

Frontiers in Plant Science, 2019
Large-scale studies that examine the responses of ectomycorrhizal fungi across biogeographic gradients are necessary to assess their role in mediating current and predicted future alterations in forest ecosystem processes.

Edaphic rather than climatic controls over C-13 enrichment between soil and vegetation in alpine grasslands on the Tibetan Plateau

, 2015
1. Soil organic carbon (SOC) dynamics is crucial for evaluating ecosystem carbon balance and its feedback to climate warming. However, it is difficult to detect statistically significant changes in SOC stock over short-time period due to its large pool ...

Revegetation of abandoned copper mines: the role of seed banks and soil amendments [PDF]

Web Ecology, 2013
Mining is one of the main causes of environmental pollution by heavy metals and (re)vegetation of mine spoils is the most effective method of preventing wind and water erosion and the consequent spread of contaminants to surrounding areas. However, plant

Dynamic changes in protist community composition along a surface water-groundwater transect in the Danube wetland Lobau, Vienna, Austria

Frontiers in Microbiology
Groundwater remains an underexplored habitat for protistan diversity and community dynamics relative to better-studied surface aquatic environments. To address this knowledge gap, we compared protistan communities at two sites, a wetland surface water ...

An approach to unraveling the coexistence of snappers (Lutjanidae) using otolith morphology

Scientia Marina, 2014
The sagittae otolith morphology of marine fishes has been used in many ecomorphological studies to explain certain ecological adaptations of species to habitat. Our study compares the sagittal otolith shapes of ten species of snappers (Family Lutjanidae)
