Post-agriculture versus post-hurricane succession in southeastern Nicaraguan rain forest
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-10)
Wecompared five-year old forests developing after agriculture to those recoveringfrom Hurricane Joan (1988) and to the pre-hurricane forest, at two sites intropical rain forest in southeastern Nicaragua. We used non-parametric ...
Seasonal acclimatization to temperature in cardueline finches
(Springer-Verlag, 1976-01)
1. Seasonal variation in metabolism and insulation was measured throughout the year in American goldfinches ( Spinus tristis ) and during winter in pine siskins ( S. pinus ).
Analysis of conditional contingency using ACTUS2 with examples from studies of animal behavior
(Springer-Verlag; Springer-Verlag and ISPA, 2002-02)
In this paper we present ACTUS2, the second version of ACTUS (Analysis of Contingency Tables Using Simulation). ACTUS2 has many new features, including analysis of data in which dependencies that make some combinations of ...
The qualitative behavior of coupled predator-prey oscillations as deduced from simple circle maps
(Elsevier, 1994-05)
Qualitative patterns of the non-equilibrium behavior of coupled consumer/resource systems, formulated as a standard circle map, are explored. Patterns of demographic locking, reflected as a "devil's staircase", are observed ...
The transformation of Saperda calcarata (Coleoptera: Cerambycidae) into a cellulose digester through the inclusion of fungal enzymes in its diet
(Springer-Verlag, 1986-12)
The larvae of the aspen borer, Saperda calcarata , which feed on the inner bark and sapwood of living aspen stems, are unable to digest cellulose. However, they can be transformed into cellulose digesters by adding the ...
Missing fossils, molecular clocks and the origin of the Melastomataceae.
(Botanical Society of America, 2003)
In a recent analysis of the historical biogeography of Melastomataceae, Renner, Clausing, and Meyer (2001; American Journal of Botany 88(7): 1290–1300) rejected the hypothesis of a Gondwana origin. Using a fossil-calibrated ...
Allometry and developmental integration of body growth in a piranha, Pygocentrus nattereri (Teleostei: Ostariophysi)
(Wiley Subscription Services, Inc., A Wiley Company, 1995-03)
Piranhas, like many teleosts, change their diets on both ontogenetic and phylogenetic time scales. Prior studies have suggested that pervasive morphological changes in body form on a phylogenetic time scale may be related ...
Tests for Positive Selection on Immune and Reproductive Genes in Closely Related Species of the Murine Genus Mus

Abstract
The ecology and evolution of tetracycline resistance
(Elsevier, 1992-09)
The use of tetracycline over the past few decades has been accompanied by a drastic increase in the frequency of tetracycline resistance in a wide range of bacterial species and genera. A diversity of resistance determinants ...
Reptile, amphibian, and lemur diversity of the Malahelo Forest, a biogeographical transition zone in southeastern Madagascar
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-10)
Ambatorongorongo Mountain lies at the historical intersection betweenhumid, spiny, and littoral forests in southeastern Madagascar. We report theresults of surveys of the herpetofauna and lemurs occurring in Malahelo ...
