Dinosaur Macroevolution and Macroecology

Annual Review of Ecology, Evolution, and Systematics, 2018
Dinosaurs were large-bodied land animals of the Mesozoic that gave rise to birds. They played a fundamental role in structuring Jurassic–Cretaceous ecosystems and had physiology, growth, and reproductive biology unlike those of extant animals. These features have made them targets of theoretical macroecology.

Complex macroevolution of pterosaurs

Current Biology, 2023
Pterosaurs, the earliest flying tetrapods, are the subject of some recent quantitative macroevolutionary analyses from different perspectives.1-2 Here, we use an integrative approach involving newly assembled phylogenetic and body size datasets, net diversification rates, morphological rates, and morphological disparity to gain a holistic understanding

Macroevolution

BioEssays, 2009
Abstract This article draws out the major philosophical issues that underlie macroevolution. This term means evolution that takes place at or above the level of the species. On the basis of the observation of fossil records, the history of life, and current biological populations scientists have concluded that organisms and taxa are ...

Macroevolution

2003
Macroevolution, or trans-specific evolution, refers to two different things in the literature on evolution. In discussions of phylogeny, it means phylogenetic branching pattern, or trends, seen at relatively high taxonomic levels (e.g., Stanley, 1979; Brooks and McLennan, 1991; Sober, 1993)—”any patterns that transcend species boundaries” (Lynch, 1991)—

Energetic Macroevolution of Invertebrates

Biology Bulletin, 2018
An analysis of research data and published data on comparable standard metabolism in invertebrates is carried out. It is shown that this parameter varies insignificantly within each family and most orders. The mean values of the comparable standard metabolism for orders are grouped around certain values.

Ecotype, ecospecies, and macroevolution

Experientia, 1948
The combined efforts of taxonomists and geneticists have succeeded to a considerable extent in solving that part of the problem of evolution which concerns the subspecific level. The detailed work of innumerable taxonomists following in the footsteps of Kleinschmidt K.
