The scientific foundations of conservation policy are the subject of a recent tripolar debate, with systematists arguing for the primacy of phylogenetic rankings, ecologists arguing for protection at the level of populations or ecosystems, and evolutionary biologists urging more attention for the factors that enhance adaptation and biodiversity. In the field of conservation genetics, this controversy is manifested in the diverse viewpoints of molecular systematists, population biologists, and… Expand
Gaia's Handmaidens: the Orlog Model for Conservation Biology
Abstract:  The Gaia hypothesis, which proposes that Earth's biota and material environment form a self-regulating system, has been influential in conservation biology, but it has not translated intoExpand
Strategies to protect biological diversity and the evolutionary processes that sustain it.

TLDR
A useful strategy may be to identify areas that are important to represent species and genetic diversity and maximize within these areas the protection of contiguous environmental gradients across which selection and migration can interact to maintain population viability and adaptive genetic diversity. Expand
Molecular biodiversity. Case study: Porifera (sponges)
TLDR
In the present review, possible strategies for making sense of molecular biodiversity using sponges as an example are outlined, using the Porifera (sponges) as a prominent example, on the basis of solid taxonomy and ecological data. Expand
ECOLOGICAL AND EVOLUTIONARY IMPLICATIONS FOR THE CONSERVATION OF PANAMANIAN GOLDEN FROGS.
TLDR
This dissertation was to contribute to the conservation of two such declining amphibians, the Panamanian golden frogs, Atelopus varius and A. zeteki, as well as demonstrate the combined utilities of morphological, ecological, and genetic analyses in providing an integrative framework for informing wildlife conservation initiatives. Expand
Facets of phylodiversity: evolutionary diversification, divergence and survival as conservation targets
TLDR
It is argued that phylogenetic diversity itself has three distinct facets—lineage diversification, character divergence and survival time—that can be quantified using distinct branch length metrics on an evolutionary tree. Expand
Conservation status of the world's hagfish species and the loss of phylogenetic diversity and ecosystem function
TLDR
The International Union for Conservation of Nature Red List Categories and Criteria were applied and nine of the 76 hagfish species were determined to be in threatened categories, indicating an elevated risk of extinction. Expand
Phylogenetic diversity and its conservation in the presence of phylogenetic uncertainty: a case study of cladoceran communities in urban waterbodies
The need to protect and preserve biodiversity is a pressing issue and requires that conservation projects be based on solid foundations. Knowledge of species evolutionary history can serve as a toolExpand
Integrating Traditional and Evolutionary Knowledge in Biodiversity Conservation: a Population Level Case Study
TLDR
It is found that TEK complemented EBK of brook charr by providing concordant and additional information about (1) population viability; (2) breeding areas and migration patterns of divergent populations; and (3) the behavioral ecology of populations within feeding areas; all of which may ultimately affect the maintenance of population diversity. Expand
Considering evolutionary processes in the use of single-locus genetic data for conservation, with examples from the Lepidoptera
TLDR
Molecular approaches must be used with caution for conservation genetics which is best accomplished using large sample sizes over extensive geography in addition to data from multiple loci, such as introgressive hybridization. Expand
The neglected majority - biodiversity inventories as an integral part of conservation biology.
TLDR
To minimize biodiversity loss and design efficient conservation strategies for entire ecosystems, ecologists and taxonomists have to look beyond the scope of their own bias and better integrate their research. Expand

  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1996
TLDR
It is shown that in constant or unpredictable environments genetic variability reduces population mean fitness and increases the risk of extinction, and in predictable, highly variable environments genetic variance may be essential for adaptive evolution and population persistence. Expand
Genetic conservation: our evolutionary responsibility.
TLDR
There is an urgent need for exploration and clarification of the genetic principles of conservation to collect and preserve irreplaceable genetic resources. Expand
An evolutionary basis for conservation strategies.
TLDR
During dynastic and feudal times, parts of kingdoms were set aside as hunting grounds for the aristocracy, thus preserving everything that dwelled therein, resulting in environmental protection for centuries, but today, with a burgeoning and expanding human population, no more than 4500 areas arc protected globally.

TLDR
With the explicit recognition of the genetic component of biodiversity in conservation legislation of many countries and in the Convention on Biological Diversity, the ESU concept is set to become increasingly significant for conservation of natural as well as captive populations. Expand

Ecological Speciation in Postglacial Fishes
TLDR
It is argued that knowledge of ecological environments is essential to understanding the origin of species in adaptive radiation, and perhaps more generally to complement (and perhaps transform) traditional genetic approaches to speciation. Expand

TLDR
Case histories are discussed in which the data of molecular genetics revealed prior systematic errors of the two possible kinds: taxonomic recognition of groups showing little evolutionary differentiation, and lack of taxonomic Recognition of phylogenetically distinct forms. Expand
Evolutionary Significant Units versus Geopolitical Taxonomy: Molecular Systematics of an Endangered Sea Turtle (genus Chelonia)
TLDR
The arguments for and against the species status of the endangered black turtle are explored, a pragmatic category for this type of taxonomy is proposed: the geopolitical species is proposed, and the practice of pre- serving species status for conservation purposes is argued. Expand
A role for ecotones in generating rainforest biodiversity
TLDR
Results suggest that natural selection may play an important role in generating rainforest biodiversity and that ecotone habitats may be a source of evolutionary novelty. Expand
