“…Even though climate change does not seem to be the main cause for the decline of the species it will probably be in the case that there are still populations left. The niche breadth of a species impacts on its survival and adaptability during intervals of environmental change (Stigall 2015). In general terms, a generalist species with wide niche breadth is more adaptable and has higher chances of surviving a change in the environment than a specialist species with narrow niche breadth highly adapted to a narrow range of resources.…”

Global biodiversity loss by anthropogenic impacts is an under-recognized form of global environmental change. Global defaunation is still poorly documented in the case of insects, showing a significant decrease in populations and diversity. The blowfly Neta chilensis (Walker 1837) is poorly known and presumed to be confined to southern-South America, with an unclear distributional pattern. It was last collected in 1984. We aimed, through Ecological Niche Models, to identify regions highly suitable for N. chilensis; to test the suitability of regions with doubtful records; to understand the impact that climatic change and human activities have had; and to identify regions with high chances to find it. We compiled 130 presence records from Argentina and Chile and 117 localities where it was sought but not found between 1987 and 2018. Results indicate that suitable conditions are restricted to southern and central Chile and to southwestern Argentina, that doubtful records are predicted in unsuitable areas, that N. chilensis occupies a narrow niche and that its decline is not mainly caused by climate changes but more probably to habitat loss and to the biological invasion. We identified two regions where the chances of finding the species are higher in the case that it is not extinct already.

“…In the fossil record, species are recognized by morphological differences, but morphological characters are essentially epistemological tools to recognize the genetically independent entities described in ontological species definitions (see Allmon ). Indeed, it is the process and causes of reproductive isolation that are important to examine when attempting to elucidate the process of speciation (Stigall , ; Rabosky ).…”

“…Like each species, each episode of speciation is unique. Speciation occurs at a particular location within a discrete interval of time within a specific evolutionary lineage (Stigall ). Therefore, by studying the pattern of speciation within and across taxa, we can begin to constrain the role of biogeography, ecology and phylogenetic history on the development of macroevolutionary patterns.…”

“…The explicit incorporation of the hierarchical structure of nature and the interplay between the economic and genealogical hierarchies provide a dynamic perspective to analyse speciation. In particular, incorporating a more synthetic macroevolutionary theory – such as presented in Myers & Saupe (), Stigall (, ) and Allmon () – with explicit consideration of abiotic environmental changes, details of species geographical ranges and niche breadth, and species migration will provide a robust framework to assess cross‐faunal biodiversity dynamics.…”

The accumulation of diversity is dependent on the production (and subsequent continuation) of new species; thus, it is important to contextualize the Great Biodiversification Event (GOBE) as the sum of a series of individual speciation events. Studies of speciation processes are only beginning to emerge for the GOBE, but early analyses of brachiopods and other taxa suggest that such research questions are tractable given appropriate data sets and analyses. In order to understand the GOBE, it is important to move from correlating diversity trends with environmental changes to explicitly assessing how correlative Earth system processes can facilitate the process and mechanisms of speciation. Explicit consideration of the hierarchical structure and biogeographical aspects of evolutionary processes provides a dynamic perspective to analyse speciation. Biogeographical processes of dispersal and vicariance provide the link between local and global diversity levels, and oscillations between these two biogeographical modalities can generate an effective speciation dynamo. Geographical isolation due to palaeogeography, numerous interoceanic islands, tectonism, glacial–interglacial cycles and newly developed habitat heterogeneity were likely key factors in promoting speciation. Understanding the processes that produced the GOBE will require careful consideration of the oceanic, climatic and tectonic processes operating during the Early Palaeozoic as well as the speciation process itself.

“…The genealogical or Linnaean part of hierarchical evolutionary theory has achieved significant conceptual, mathematical, and empirical progress on the meaning, scope, and significance of multilevel selection or sorting and cross-level effects in evolution and emergence of individuals (Lewontin 1970;Eldredge and Gould 1972;Stanley 1975Stanley , 1979Eldredge and Salthe 1984;Vrba and Eldredge 1984;Eldredge 1985Eldredge , 1989Eldredge , 1996Salthe 1985;Vrba and Gould 1986;Lloyd and Gould 1993;Lloyd 1994;Maynard Smith and Szathmáry 1998;Gould and Lloyd 1999;Lieberman and Vrba 2005;Okasha 2006;Jablonski 2007Jablonski , 2017. The economic side of biology is also recognized as having hierarchical structure (Allen and Starr 1982;Eldredge and Salthe 1984;Eldredge 1985;Leibold et al 2004;Holyoak et al 2005;Bennington et al 2009;Tomašových and Kidwell 2010), connected in many nontrivial ways to the genealogical hierarchy and through the feedbacks forming the eco-genealogical dynamics (Eldredge 1985(Eldredge , 1999(Eldredge , 2003Van Valen 1989;Vrba 1993;Stigall 2015;Tëmkin and Eldredge 2015); for a recent review of the "dual hierarchy approach," see Rosenberg (2022). The economic side of biology can be further understood in two competitive hierarchical ways that are mirrored by the institutional subdivisions in ecology and Earth sciences: as a hierarchy of interacting populations forming nested communities of different sizes (population ecology/paleoecology view) or as a hiera...…”

The process of evolution and the structures it produces are best understood in the light of hierarchy theory. The biota traditionally is described by either the genealogical Linnaean hierarchy or economic hierarchies of communities or ecosystems. Here we describe the Bretskyan hierarchy—a hybrid eco-genealogical hierarchy that consists of nested sets of different-sized, usually polyphyletic communities of interacting individuals separated from other such communities in space and time at multiple scales. The Bretskyan hierarchy consists of elements that have both genealogical and economic properties and functions—situated between, and connecting the elements of, the economic hierarchies (Vernadskyan) and the genealogical (Linnaean) hierarchy. The described hierarchy at lower tiers is populated by holobionts, individuals composed of multiple polyphyletic lineages integrated by functional interactions or biotically fabricated structures, such as membranes. At larger spatial tiers and longer time scales, the members of the Bretskyan hierarchy are of a more diffuse nature, partially due to the small size and relatively short duration of us as observers of larger and longer-lasting structures, here described as geobiomes. Their individuality is externally forced and directly tied to the spatial and temporal physical structures of our planet. These are sub-bioprovinces and bioprovinces—large and effectively isolated spatiotemporal structures of biota integrated internally by coevolution and individuated externally by a hierarchy of barriers. Gaia is here understood as the largest eco-genealogical individual compartmentalized by the outer space of the Earth and integrated at long time scales by biotic interactions and plate tectonic mixing of biota. The existence of a hierarchy of barriers and multilevel allopatry suggests that geographic isolation takes part not only in individuating species lineages, but also in producing coherent complexes of separate lineages forming bioprovinces at multiple space and time scales. The sizes, configurations, and durations of Bretskyan units are directly tied to geodynamics, demonstrating the central role of the physical planet in the processes of individuation and merging of geobiomes and the control of coevolution, and all its ramifications, at multiple space and time scales. The Bretskyan hierarchy also allows the integration of previously unconnected themes—“egalitarian” major transitions in individuality (e.g., eukaryogenesis) and some of the megatrajectories in the history of life—into a single theoretical framework of spatial and temporal scaling of eco-genealogy. The pervasive scaling of geodynamical processes and the direct connection of geodynamics to the dynamics of Bretskyan units allows us to formulate conjectures on the scales and limits of spatial and temporal contingency and competitiveness of biotas in evolution.
