The Metapopulation Ecology of the Red‐Spotted Newt, Notophthalmus viridescens (Rafinesque)
  • D. E. Gill
  • Environmental Science, Biology
  • 1 February 1978
TLDR
It is suggested that beaver ponds have the necessary attributes of small size and temporal instability to which the life—history patterns of newts seems adapted and that the eft stage is the mechanism of dispersibility to new ponds.

Interpreting Geographic Variation in Life-History Traits
TLDR
Heritability and survivorship data support the general notion that fitness traits should have low levels of additive genetic variation, but also suggest that antagonistic pleiotropy may act to preserve genetic variation in fitness traits under simultaneous selection.

COUNTERGRADIENT SELECTION IN THE GREEN FROG
Plants and Breeding Bird Response on a Managed Conservation Reserve Program Grassland in Maryland
TLDR
It is recommended the management of grasslands restored for birds include spatial and temporal rotation of prescribed fire and herbicide applications to sustain vegetation physical structure rather than species composition.

COUNTERGRADIENT SELECTION IN THE GREEN FROG, RANA CLAMITANS
TLDR
The present investigation reports the results of natural history observations and an experimental investigation designed to compare postembryonic rates of growth and development of montane and lowland populations of the green frog, Rana clamitans, to determine whether the observed populational differences in growth andDevelopment are induced ontogenetically by the ambient environment or controlled genetically.

  • 1 January 1974
TLDR
It is concluded that species dominance in competition can not in principle be predicted from knowledge of r or K alone.

PUTTING A CART BEFORE THE SEARCH: SUCCESSFUL HABITAT PREDICTION FOR A RARE FOREST HERB
The realms of rare species conservation and metapopulation biology theory are often interrelated, and hence share several basic challenges. Two of the most important are the critical and frequently…

EFFECTIVE POPULATION SIZE AND INTERDEMIC MIGRATION RATES IN A METAPOPULATION OF THE RED‐SPOTTED NEWT, NOTOPHTHALMUS VIRIDESCENS (RAFINESQUE)
  • D. E. Gill
  • Biology
    Evolution; international journal of organic…
  • 1 December 1978
In a species that is subdivided into discrete breeding demes, three unique dynamic forces may exert strong influence on its evolution: genetic drift, demic extinction, and interdemal migration.…
