Abstract For a long time ecologists have questioned on the variations of biodiversity across the latitudinal gradient. Recently, it has emerged that the changes in β-diversity are caused simply by changes in the sizes of species pools. In this study, the species pool size and the fractal nature of ecosystems was combined to clarify some general patterns of this gradient. Considering temperature, humidity and NPP as the main variables of an ecosystem niche and as the axis of the polygon in the…

Abstract: Among tropical areas, Africa is considered to be poor in terms of biodiversity as compared with Amazon or South-East Asia, especially with respect to forest diversity. Despite this lower

It is shown that saprotrophic communities of fungi are widely distributed in the glacier retreating area with higher relative abundances of saprotroph ascomycetes at early successional stages.

• Biology, Environmental Science

There might be a difference in the behavior of wild and captive isopods in their volvation frequency and duration of tonic immobility due to environmental factors (i.e. predation) that induce learning-related behavioral changes.

### The need to understand the stability of arctic vegetation during rapid climate change: An assessment of imbalance in the literature

• Environmental Science
Ambio

It is found that greening studies dominate the literature though two relatively small areas of the Arctic are disproportionately represented for this main change process; the need to understand the mechanisms driving Arctic ecosystem stability, and the potential longer-term consequences of remaining stable in a rapidly changing climate.

### The Niche, Its Hypervolume and the Entropy of Existence

This chapter will focus on developing some underlying ideas and principles that are likely to be applicable to all biological systems, no matter their origin or overall design, and should be able to consider any number of planets in terms of their habitability for life in general—and interms of whether complex and intelligent biology becomes likely.

### Disentangling the Drivers of β Diversity Along Latitudinal and Elevational Gradients

• Environmental Science
Science
• 2011
It is shown that sampling alone predicts changes in β diversity caused simply by changes in the sizes of species pools, and there is no need to invoke differences in the mechanisms of community assembly in temperate versus tropical systems to explain these global-scale patterns of β diversity.

### The fractal nature of nature: power laws, ecological complexity and biodiversity.

• Environmental Science
Philosophical transactions of the Royal Society of London. Series B, Biological sciences
• 2002
Recent progress and future prospects for understanding the mechanisms that generate power laws are described, and for explaining the diversity of species and complexity of ecosystems in terms of fundamental principles of physical and biological science are described.

### A conceptual model of new hypothesis on the evolution of biodiversity

• R. Gatti
• Environmental Science, Biology
• 2016
A new graphic model is proposed that reviews the past and present, and sometimes debated, trends in biodiversity and evolutionary science, pointing out the importance of the avoidance of competition, the biological history, the endogenosymbiosis and the three-dimensionality as the main forces that structure ecosystems and allow the evolution of biological diversity.

### Primate species richness is determined by plant productivity: implications for conservation.

• Environmental Science
Proceedings of the National Academy of Sciences of the United States of America
• 1997
It is shown that local richness of Neotropical primates (platyrrhines) is influenced by both historical biogeography and productivity but not by tree species richness or seasonality, which indicates that habitats with the highest plant productivity are also the richest for many important primary consumers.

### A sideways look at patterns in species richness, or why there are so few species outside the tropics

• Environmental Science
• 1996
What causes the widely observed latitudinal gradients in species richness remains one of the key unanswered questions in ecology. Despite numerous hypotheses generating a wealth of tests, no

• 2011
It is found that using a three-dimensional model as hypervolume and testing the theory on a Mediterranean, temperate and tropical forest ecosystem it is possible to demonstrate that each species plays a fundamental role in facilitating the colonization by other species by simply modifying the environment and exponentially increasing the available niches' space and number.
