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

Ecology and abundance of zooplankton in Karanja reservoir [PDF]
Environmental Monitoring and Assessment, 2008 The present work aims to study the Zooplankton seasonal distribution and diversity in Karanja reservoir, Bidar district for the period of two years from October 2001 to September 2003. We have recorded 36 species of which, 15 species belongs to rotifera, 11 species belongs to cladocera, nine species belongs to copepoda and ostracoda three species ...

Network properties, species abundance and evolution in a model of evolutionary ecology [PDF]
Journal of Theoretical Biology, 2004 We study the evolution of the network properties of a populated network embedded in a genotype space characterised by either a low or a high number of potential links, with particular emphasis on the connectivity and clustering. Evolution produces two distinct types of network.

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 ...

Global abundance patterns, diversity, and ecology of Patescibacteria in wastewater treatment plants [PDF]
Microbiome, 2023 Abstract Background Microorganisms are responsible for nutrient removal and resource recovery in wastewater treatment plants (WWTPs), and their diversity is often studied by 16S rRNA gene amplicon sequencing. However, this approach underestimates the abundance and diversity of Patescibacteria due to the low coverage of ...

Abundance and ecological associations of small mammals [PDF]
The Journal of Wildlife Management, 2019 ABSTRACTEffective conservation and management of small mammals require knowledge of the population dynamics of co‐occurring species. We estimated the abundances, autocorrelations, and spatiotemporal associations of 4 small‐mammal species from 2011–2016 using live‐trapping mark‐recapture methods on 9 sites across elevation and canopy openness gradients ...

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.

Species abundance and asymmetric interaction strength in ecological networks [PDF]
Oikos, 2007 The strength of interactions among species in a network tends to be highly asymmetric. We evaluate the hypothesis that this asymmetry results from the distribution of abundance among species, so that species interactions occur randomly among individuals. We used a database on mutualistic and antagonistic bipartite quantitative interaction networks.

Relationships between body size and abundance in ecology
Trends in Ecology & Evolution, 2007 Body size is perhaps the most fundamental property of an organism and is related to many biological traits, including abundance. The relationship between abundance and body size has been extensively studied in an attempt to quantify the form of the relationship and to understand the processes that generate it.
