Seed bank persistence of a South American cordgrass in invaded northern Atlantic and Pacific Coast estuaries.

AoB Plants 2021 Jun 8;13(3):plab014. Epub 2021 Apr 8.

Departamento de Biología Vegetal y Ecología, Facultad de Biología, Universidad de Sevilla, Apartado 1095, 41080, Sevilla, Spain.

Invasive alien plant species impart considerable impacts that contribute to the decline of biodiversity worldwide. The ability of an invasive species to overcome barriers to establish and spread in new environments, and the long-term effects of plant invasions supporting their persistence are keys to invasion success. The capacity of introduced species to form soil seed banks can contribute to their invasiveness, yet few studies of invaders have addressed seed bank dynamics. Read More

Stochasticity constrained by deterministic effects of diet and age drive rumen microbiome assembly dynamics.

Nat Commun 2020 04 20;11(1):1904. Epub 2020 Apr 20.

Department of Life Sciences, Ben-Gurion University of the Negev and the National Institute for Biotechnology in the Negev, Marcus Family Campus, Beer-Sheva, Israel.

How complex communities assemble through the animal's life, and how predictable the process is remains unexplored. Here, we investigate the forces that drive the assembly of rumen microbiomes throughout a cow's life, with emphasis on the balance between stochastic and deterministic processes. We analyse the development of the rumen microbiome from birth to adulthood using 16S-rRNA amplicon sequencing data and find that the animals shared a group of core successional species that invaded early on and persisted until adulthood.

Traits linked with species invasiveness and community invasibility vary with time, stage and indicator of invasion in a long-term grassland experiment.

Ecol Lett 2019 Apr 19;22(4):593-604. Epub 2019 Feb 19.

Department of Ecology, Evolution & Behavior, University of Minnesota, St. Paul, MN, 55108, USA.

Much uncertainty remains about traits linked with successful invasion - the establishment and spread of non-resident species into existing communities. Using a 20-year experiment, where 50 non-resident (but mostly native) grassland plant species were sown into savannah plots, we ask how traits linked with invasion depend on invasion stage (establishment, spread), indicator of invasion success (occupancy, relative abundance), time, environmental conditions, propagule rain, and traits of invaders and invaded communities. Trait data for 164 taxa showed that invader occupancy was primarily associated with traits of invaders, traits of recipient communities, and invader-community interactions. Read More

The lost world of Cuatro Ciénegas Basin, a relictual bacterial niche in a desert oasis.

Elife 2018 11 20;7. Epub 2018 Nov 20.

Departamento de Ecología Evolutiva, Instituto de Ecología, Universidad Nacional Autónoma de México, Coyoacán, Mexico.

Barriers to microbial migrations can lead adaptive radiations and increased endemism. We propose that extreme unbalanced nutrient stoichiometry of essential nutrients can be a barrier to microbial immigration over geological timescales. At the oasis in the Cuatro Ciénegas Basin in Mexico, nutrient stoichiometric proportions are skewed given the low phosphorus availability in the ecosystem. Read More

Hydrogen Dynamics in Cyanobacteria Dominated Microbial Mats Measured by Novel Combined H/HS and H/O Microsensors.

Front Microbiol 2017 18;8:2022. Epub 2017 Oct 18.

Section for Microbiology, Department of Bioscience, Aarhus University, Aarhus, Denmark.

Hydrogen may accumulate to micromolar concentrations in cyanobacterial mat communities from various environments, but the governing factors for this accumulation are poorly described. We used newly developed sensors allowing for simultaneous measurement of HS and H or O and H within the same point to elucidate the interactions between oxygen, sulfate reducing bacteria, and H producing microbes. After onset of darkness and subsequent change from oxic to anoxic conditions within the uppermost ∼1 mm of the mat, H accumulated to concentrations of up to 40 μmol L in the formerly oxic layer, but with high variability among sites and sampling dates.

Grass invasion increases top-down pressure on an amphibian via structurally mediated effects on an intraguild predator.

Ecology 2014 Jul;95(7):1724-30

Plants serve as both basal resources and ecosystem engineers, so plant invasion may exert trophic influences on consumers both via bottom-up processes and by altering the environmental context in which trophic interactions occur. To determine how these mechanisms affect a native predator we used a mark-recapture study in eight pairs of 58-m2 field enclosures to measure the influence of Japanese stilt grass invasion on 3200 recently metamorphosed American toads. Toad survivorship was lower in invaded habitats despite abiotic effects that favor amphibians. Read More
