Reproductive Biology of Asteraceae on Oceanic Islands
Asteraceae are among the most abundant angiosperm families on oceanic islands. The reproductive biology of Asteraceae is reviewed and the attributes of the family contributing to their success on islands are d...

The transition to selfing in Azorean Tolpis (Asteraceae)
Asteraceae have the most endemic species of any flowering plant family in oceanic archipelagos, and these insular endemics display a higher frequency of self-compatibility (SC) compared to mainland composites....

Open AccessParental experience modifies the Mimulus methylome
Transgenerational plasticity occurs when the environmental experience of an organism modifies the growth and development of its progeny. Leaf damage in Mimulus guttatus exhibits transgenerational plasticity media...

Breeding systems in Tolpis (Asteraceae) in the Macaronesian islands: the Azores, Madeira and the Canaries
Plants on oceanic islands often originate from self-compatible (SC) colonizers capable of seed set by self-fertilization. This fact is supported by empirical studies, and is rooted in the hypothesis that one (...

Open AccessDNA methylation and gene expression in Mimulus guttatus
The presence of methyl groups on cytosine nucleotides across an organism’s genome (methylation) is a major regulator of genome stability, crossing over, and gene regulation. The capacity for DNA methylation to...

Testing the fisherian mechanism: examining the genetic correlation between male song and female response in waxmoths
Models of indirect (genetic) benefits sexual selection predict linkage disequilibria between genes that influence male traits and female preferences, owing to either non-random mate choice or physical linkage....

Article
Testing the rare-alleles model of quantitative variation by artificial selection
The rare-alleles model of quantitative variation posits that a common allele (the ‘wild-type’) and one or more rare alleles segregate at each locus affecting a quantitative trait; a scenario predicted by sever...

Article
A model for the evolution of communal foraging in hierarchically structured populations
A kin selection model is described for populations in which groups of interacting individuals (trait groups, sensu Wilson 1975) are spatially situated within larger aggregations. The model predicts the optimal...

Central Nervous System Prophylaxis with Intermittent Intrathecal Methotrexate and Fractional Radiation in Childhood Acute Lymphoblastic Leukemia
Following the initial studies of the St. Jude group (1), high dose (2400 rad) cranial irradiation plus intrathecal (IT) methotrexate (MTX) or craniospinal irradiation given shortly after remission induction ha...
