Tree phylogenetic diversity promotes host-parasitoid interactions.

Evidence from grassland experiments suggests that a plant community's phylogenetic diversity (PD) is a strong predictor of ecosystem processes, even stronger than species richness per se This has, however, never been extended to species-rich forests and host-parasitoid interactions. We used cavity-nesting Hymenoptera and their parasitoids collected in a subtropical forest as a model system to t...

Gap Heuristics and Tree Construction using gaps

The construction of multiple sequence alignments (MSAs) is a fundamental problem in biology. Yet the problem cannot be solved exactly in most cases, as it is exponential in the number of sequences. It is therefore highly desirable to develop heuristics. It is reasonable that not every heuristic starts from scratch, but uses the expertise that has evolved over the years. We present a set of heur...

Ghost-tree: creating hybrid-gene phylogenetic trees for diversity analyses.

BACKGROUND Fungi play critical roles in many ecosystems, cause serious diseases in plants and animals, and pose significant threats to human health and structural integrity problems in built environments. While most fungal diversity remains unknown, the development of PCR primers for the internal transcribed spacer (ITS) combined with next-generation sequencing has substantially improved our ab...

Learning to Run Heuristics in Tree Search

“Primal heuristics” are a key contributor to the improved performance of exact branch-and-bound solvers for combinatorial optimization and integer programming. Perhaps the most crucial question concerning primal heuristics is that of at which nodes they should run, to which the typical answer is via hard-coded rules or fixed solver parameters tuned, offline, by trial-and-error. Alternatively, a...

Using invariants for phylogenetic tree construction

Phylogenetic invariants are certain polynomials in the joint probability distribution of a Markov model on a phylogenetic tree. Such polynomials are of theoretical interest in the field of algebraic statistics and they are also of practical interest — they can be used to construct phylogenetic trees. This paper is a self-contained introduction to the algebraic, statistical, and computational ch...
