Reconciling cooperation, biodiversity and stability in complex ecological communities [PDF]

Scientific Reports, 2019
AbstractEmpirical evidences show that ecosystems with high biodiversity can persist in time even in the presence of few types of resources and are more stable than low biodiverse communities. This evidence is contrasted by the conventional mathematical modeling, which predicts that the presence of many species and/or cooperative interactions are ...

Biodiversity estimates and ecological interpretations of meiofaunal communities are biased by the taxonomic approach [PDF]

Communications Biology, 2018
Abstract Accurate assessments of biodiversity are crucial to advising ecosystem-monitoring programs and understanding ecosystem function. Nevertheless, a standard operating procedure to assess biodiversity accurately and consistently has not been established. This is especially true for meiofauna, a diverse community (>20 phyla) of

Ecological interactions shape the evolution of flower color in communities across a temperate biodiversity hotspot [PDF]

Evolution Letters, 2021
AbstractProcesses driving the divergence of floral traits may be integral to the extraordinary richness of flowering plants and the assembly of diverse plant communities. Several models of pollinator-mediated floral evolution have been proposed; floral divergence may (i) be directly involved in driving speciation or may occur after speciation driven by

Community size can affect the signals of ecological drift and niche selection on biodiversity [PDF]

Ecology, 2020
AbstractEcological drift can override the effects of deterministic niche selection on small populations and drive the assembly of some ecological communities. We tested this hypothesis with a unique data set sampled identically in 200 streams in two regions (tropical Brazil and boreal Finland) that differ in macroinvertebrate community size by fivefold.

Ecological implications of reduced pollen deposition in alpine plants: a case study using a dominant cushion plant species [v1; ref status: indexed, http://f1000r.es/3mb]

F1000Research, 2014
The reproductive assurance hypothesis states that self-incompatible female plants must produce twice the number of seeds relative to their self-compatible hermaphroditic counterparts to persist in gynodioecious populations.

Grassland ecology in China: perspectives and challenges [PDF]

Frontiers of Agricultural Science and Engineering, 2018
During the last few decades, there have been an increasing number of studies on grassland ecology in China, involving the classic ecology concepts or theories and the applicable ecological principles of grassland conservation or management.

First visual record of rare purple-colored dogwhelks (Nucella lapillus) on the Atlantic coast of Nova Scotia, Canada [version 2; referees: 1 approved, 2 approved with reservations]

F1000Research, 2017
The dogwhelk Nucella lapillus is a rocky intertidal gastropod of the North Atlantic coast. Individual shell color varies. Common colors range between white and brown, with darker dogwhelks being more affected by heat stress than lighter-colored ...

Drawing ecological inferences from coincident patterns of population‐ and community‐level biodiversity [PDF]

Molecular Ecology, 2014
AbstractBiodiversity is comprised of genetic and phenotypic variation among individual organisms, which might belong to the same species or to different species. Spatial patterns of biodiversity are of central interest in ecology and evolution for several reasons: to identify general patterns in nature (e.g.

Laboratory growth of denitrifying water column microbial consortia from deep-sea shipwrecks in the northern Gulf of Mexico [version 3; referees: 2 approved]

F1000Research, 2018
Background: Shipwrecks serve as a rich source for novel microbial populations that have largely remained undiscovered. Low temperatures, lack of sunlight, and the availability of substrates derived from the shipwreck’s hull and cargo may provide an ...

Ecosystem services and ecological degradation of communal wetlands in a South African biodiversity hotspot [PDF]

Royal Society Open Science, 2019
Wetlands provide important ecosystem services to rural communities. However, wetlands are often on communal land, so they may become degraded when individual users act to maximize their personal benefit from ecosystem services without bearing the full environmental costs of their actions. Although it is possible to manage communal resources sustainably,
