The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]
, 2008 1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Stochastic model for the species abundance problem in an ecological community [PDF]
Physical Review E, 2004 We propose a model based on coupled multiplicative stochastic processes to understand the dynamics of competing species in an ecosystem. This process can be conveniently described by a Fokker-Planck equation. We provide an analytical expression for the marginalized stationary distribution.

Testing Ecological Theory with Lianas [PDF]
, 2018 Lianas constitute a diverse polyphyletic plant group that is advancing our understanding of ecological theory. Specifically, lianas are providing new insights into the mechanisms that control plant distribution and diversity maintenance.

Species Lists in Ecology and Conservation: Abundances Matter [PDF]
Conservation Biology, 2002 In a paper in the October 2001 issue of Conservation Biology , Gomez de Silva and Medellin (2001) studied the problem of incomplete species lists in conservation and macroecology. They based their study on the observation that “studies of species diversity, macroecology, and conservation are usually based on lists of species, but lists found in the ...

The structure of ant–plant ecological networks: Is abundance enough? [PDF]
Ecology, 2014 Knowledge of the mechanisms that shape biodiversity is essential to understand the ecological and evolutionary dynamics of interacting species. Recent studies posit that most of the organization of mutualistic networks is shaped by differences in species abundance among interacting species. In this study, we examined the mutualism involving plants with

SUMMER ABUNDANCE AND ECOLOGY OF ZOOPLANKTON IN THE GULF STREAM
The Biological Bulletin, 1975 We have described the results of laboratory analyses of 42 horizontal tows using a Clarke-Bumpus plankton sampler with a 100 µ emmesh net in the Gulf Stream. Classifications of 20 zooplankton taxa have been made for the 42 hauls. Calanoids dominate the hauls. It was found that the zooplankton population distribution and density varied considerably from

Bacterial community profiles and Vibrio parahaemolyticus abundance in individual oysters and their association with estuarine ecology [PDF]
, 2017 Oysters naturally harbor the human gastric pathogen Vibrio parahaemolyticus, but the nature of this association is unknown. Because microbial interactions could influence the accumulation of V. parahaemolyticus in oysters, we investigated the composition

Heat Stress Altered the Vaginal Microbiome and Metabolome in Rabbits
Frontiers in Microbiology, 2022 Heat stress can have an impact on parental gamete maturation and reproduction functions. According to current research, the microbial composition of the vaginal cavity is species specific. Pregnancy, menstruation, and genital diseases have been linked to

Ecological niche structure and rangewide abundance patterns of species [PDF]
Biology Letters, 2013 Spatial abundance patterns across species' ranges have attracted intense attention in macroecology and biogeography. One key hypothesis has been that abundance declines with geographical distance from the range centre, but tests of this idea have shown that the effect may occur indeed only in a minority of cases.

Applying trait-based models to achieve functional targets for theory-driven ecological restoration [PDF]
, 2014 Manipulating community assemblages to achieve functional targets is a key component of restoring degraded ecosystems. The response-and-effect trait framework provides a conceptual foundation for translating restoration goals into functional trait targets,
