Here, I address two other problems raised by this article. A review of published experimental results led the authors to conclude that “diversity enhanced ecosystem stability”, where this is defined as “the ability to withstand recurrent perturbations”. This curious statement reverses modern theory of ecological diversity in the ocean as discussed, for instance, by Ramón Margalef. Ecosystems of...

Experimental transmissions of cloned Theileria parva in cattle with Rhipicephalus appendiculatus ticks were compared to transmissions with uncloned T. parva during studies on the potential for genetic recombination during syngamy of Theileria to produce antigenic diversity for evasion of bovine immunity. Prevalence and abundance of T. parva infection in adult ticks, which resulted from the feed...

Recent advances in analytical methods and exploration of regional diversity patterns in greater depth than simple whole-fauna patterns may change our understanding of the determinants of latitudinal gradients in species richness. Using a comprehensive database on the geographical distributions of the large fauna of endemic shorefishes from the Tropical Eastern Pacific (TEP), we delineated latit...

The community structure of hard and soft corals, with an emphasis on hard corals, was determined by means of line-transects on 9 onand off-shore reefs of different type and different wave exposure in the Northern Red Sea near Hurghada in Egypt. Coral communities were found to differentiate along a horizontal windand wave-exposure gradient. Exposed communities were dominated by Acropora species,...

Fungal endophytes are microorganisms that grows within living plant tissues without any symptoms of infection, and develop with plants for a major part of their life cycle. There is an endophyte for almost every plant in the world. Several novel bioactive compounds which can show a revolution in industrial agricultural and pharmaceutical sectors have been recently synthesized from endophytic fu...

This study examined the perceptions of male and female employees across various categories (i.e. general, minority, disabled, and socially disadvantaged employees) about HR diversity and employers’ efforts for promoting and valuing diversity in Indian organizations. The study found that women in general attached more importance to value diversity than men. Women were of the strong view that org...

We propose a new selection diversity scheme, called -selection diversity, that selects the branch providing the largest magnitude of log-likelihood ratio (LLR). The LLR for BPSK signals in fading channels is found to be proportional to the product of the fading amplitude and the matched filter output after phase compensation. The proposed -selection diversity scheme is shown to be optimal in th...

Different approaches for the assessment of biodiversity bymeans of remote sensingwere developed over the last decades. A new approach, based on the spectral variation hypothesis, proposes that the spectral heterogeneity of a remotely sensed image is correlated with landscape structure and complexity which also reflects habitat heterogeneity which itself is known to enhance species diversity. In...

Diversity and species composition of endophytic fungi on leaves of 11 tree 10 species in Betulaceae were studied, with reference to climatic, tree species, and seasonal 11 variations. A total of 186 fungal isolates were obtained from 190 leaves collected in a 12 subalpine, a cool temperate, and a subtropical forest in Japan and were divided into 46 13 operational taxonomic units (OTUs) accordin...
