The Latitudinal Gradient in Geographical Range: How so Many Species Coexist in the Tropics
TLDR
It is suggested that the greater annual range of climatic conditions to which individuals in high-latitudes environments are exposed relative to what low-latitude organisms face has favored the evolution of broad climatic tolerances in high -latitude species.Abstract:
The latitudinal gradient in species richness is paralleled by a latitudinal gradient in geographical-range size called Rapoport's rule. It is suggested that the greater annual range of climatic con...read more

Quantifying biodiversity: procedures and pitfalls in the measurement and comparison of species richness
TL;DR: A series of common pitfalls in quantifying and comparing taxon richness are surveyed, including category‐subcategory ratios (species-to-genus and species-toindividual ratios) and rarefaction methods, which allow for meaningful standardization and comparison of datasets.
Journal ArticleDOI
Convention on Biological Diversity
TL;DR: In this article, the authors propose case studies on various topics to identify management practices, technologies and policies that promote the positive and mitigate the negative impacts of agriculture on biodiversity, and enhance productivity and the capacity to sustain livelihoods.

Global patterns in biodiversity
TL;DR: This work states that the distribution of biodiversity across the Earth can be described in terms of a relatively small number of broad-scale spatial patterns, and theory is developing rapidly, improving in its internal consistency, and more readily subjected to empirical challenge.

TL;DR: Diversity of most fungal groups peaked in tropical ecosystems, but ectomycorrhizal fungi and several fungal classes were most diverse in temperate or boreal ecosystems, and manyfungal groups exhibited distinct preferences for specific edaphic conditions (such as pH, calcium, or phosphorus).

LATITUDINAL GRADIENTS OF BIODIVERSITY:Pattern,Process,Scale,and Synthesis
TL;DR: An extensive survey of the literature is conducted and a synthetic assessment of the degree to which variation in patterns is a consequence of characteristics of scale or taxon is provided.

Food Web Complexity and Species Diversity
TL;DR: It is suggested that local animal species diversity is related to the number of predators in the system and their efficiency in preventing single species from monopolizing some important, limiting, requisite in the marine rocky intertidal.
Book
Ecology: The Experimental Analysis of Distribution and Abundance
TL;DR: This book discusses ecosystem dynamics under Changing Climates, which includes community dynamics at the community level, and factors that limit Distributions, which limit the amount of variation in population size.

A General Hypothesis of Species Diversity
TL;DR: A new hypothesis, based on differences in the rates at which populations of competing species approach competitive equilibrium (reduction or exclusion of some species), is proposed to explain patterns of species diversity.

Marine Benthic Diversity: A Comparative Study
TL;DR: A within-habitat analysis was made of the bivalve and polychaete components of soft-bottom marine faunas which differed in latitude, depth, temperature, and salinity, and it was indicated that species number is the more valid diversity measurement.

Turnover Rates in Insular Biogeography: Effect of Immigration on Extinction
TL;DR: This new model predicts that when immigration rates are high relative to extinction rates, turnover rate is directly related to the distance between an island and the source of colonizing species.
