Ecological ranking of Phanerozoic biodiversity crises: ecological and taxonomic severities are decoupled
The past two decades have seen extensive analyses of the taxonomic severity of major biodiversity crises in geologic time. In contrast, we propose here an alternative analysis of the ecological severity of biodiversity crises. It is clear that the ecological impacts of the five Phanerozoic biodiversity crises were not all the same. Ranking the five Phanerozoic biodiversity crises by ecological ...
متن کاملThe multiple scales of biodiversity
The claim that measures of global biodiversity dynamics are meaningless is based upon several methodological problems, including underrepresentation of tropical regions in ‘‘global’’ Phanerozoic data sets, inaccuracies in taxonomic data, non-equivalence of higher taxa among groups of organisms, and uneven sampling intensity across groups, environments, and time intervals. Some of these problems...
متن کاملPunctuated non-equilibrium and niche conservatism explain biodiversity fluctuations through the Phanerozoic
Fluctuations in biodiversity, both large and small, are pervasive through the fossil record, yet we do not understand the processes generating them. Here we use a novel extension of theory from non-equilibrium statistical physics to show that three universal properties of macroevolution—punctuated adaptive radiation, niche conservatism and resultant heterogeneity of diversification rates betwee...
متن کاملAssessment and Spatial Planning of Landscape Ecological Connectivity for Biodiversity Management (Case Study: Qazvin Province)
Habitat and ecosystem fragmentation and, consequently, the loss of landscape connectivity are major causes of biodiversity destruction, leading to disruption of material, energy, and information flow at the landscape scale. Given the importance of this issue, the current study aimed to evaluate the ecological connectivity and spatial planning of Qazvin Province, in order to re-establish and pro...
متن کاملThe Application of Ecological Principles to Urban and Urbanizing Landscapes
gene sequencers through advanced computers and networking to global-observing satellites-coupled with keen scientific curiosity present an opportunity for unprecedented advances. Together, we can make ecological science a mainstay of sustainability. While pursuing that goal, we need to ensure that our best efforts are made available to society along the way. The time of science remaining in its...
