Analyzing the Role of Increasing Water Pollution on Species-Richness, Interspecific-Competition and Abundance-Unevenness in Reef-Associated Fish Communities, off Jakarta Bay (Indonesia)

Jean Béguinot · International Journal of Environment and Climate Change · 2021

Not far from the exceptionally rich ‘Coral Triangle’ on the one hand but, on the other hand, exposed to strongly varying degree of anthropogenic environmental stresses, the reef-associated fish assemblages all along ‘Seribu Islands’ (off Jakarta Bay) are, thus, confronted to both...

Influence of Fishing Activity on Total Species Richness and Abundance Unevenness in Reef Fish Communities: A Case Study in a Brazilian Tropical Coral Complex

Jean Béguinot · International Journal of Environment and Climate Change · 2019

The internal organization of reef-fish communities, particularly the species richness and the hierarchical structuring of species abundances, depends on many environmental factors, including fishing intensity and proportion of macroalgal cover which are expected to have determina...

Analysing the Role of Environmental Stresses on Species Richness and the Process of Hierarchical Structuring of Species Abundances in Marine Gastropods communities at Suva (Fiji Islands)

Jean Béguinot · International Journal of Environment and Climate Change · 2018

Anthropogenic environmental stresses, especially physio-chemical pollution, are causing steadily increasing threat to many ecosystems, among which coastal marine communities in tropical shallow waters are especially sensitive. In particular, species-rich marine gastropod assembla...

Estimating True Species Richness and the Degree of Hierarchical Structuring of Species Abundances in Eight Frog Communities from the North-Western Ghats of India

Jean Béguinot · International Journal of Environment and Climate Change · 2018

The Distribution of Species Abundances within natural communities – when properly analysed – can provide essential information regarding general aspects of the internal organisation of these communities. In particular, true species richness on the one hand and the intensity of th...

Extrapolation of the Species Accumulation Curve Associated to “Chao” Estimator of the Number of Unrecorded Species: A Mathematically Consistent Derivation

Jean Béguinot · Annual Research & Review in Biology · 2016

Incomplete samplings are doomed to become common practice for many inventories of biodiversity, thereby inviting to extrapolate what the rate of accumulation of newly recorded species would be if sampling was to be continued any further. For this purpose, a new derivation is prov...

Basic Theoretical Arguments Advocating Jackknife-2 as Usually being the Most Appropriate Nonparametric Estimator of Total Species Richness

Jean Béguinot · Annual Research & Review in Biology · 2016

A lot of nonparametric estimators of the number of unrecorded species after partial sampling of an assemblage of species, have been proposed in the literature. Unfortunately, these different types of estimators provides substantially divergent predictions. While empirical compari...

Extrapolation of the Species Accumulation Curve for Incomplete Species Samplings: A New Nonparametric Approach to Estimate the Degree of Sample Completeness and Decide when to Stop Sampling

Jean Béguinot · Annual Research & Review in Biology · 2015

Incomplete species samplings are deemed to remain the common practice in those groups of animals, such as small or micro- invertebrates, with numerous species that often are more or less difficult to detect in the field. Thus, extrapolating the Species Accumulation Curve as far a...

When Reasonably Stop Sampling? How to Estimate the Gain in Newly Recorded Species According to the Degree of Supplementary Sampling Effort

Jean Béguinot · Annual Research & Review in Biology · 2015

Aim: Register new species gradually becomes more difficult as sampling of a community progresses, addressing increasingly rarer species. Thus, although biodiversity assessments would ideally require complete samplings, only partial samplings are ordinarily achieved when species a...
