Network approaches to ecological questions have been increasingly used, particularly in
recent decades. The abstraction of ecological systems – such as communities – through …

Linking interspecific interactions (eg, mutualism, competition, predation, parasitism) to
macroevolution (evolutionary change on deep timescales) is a key goal in biology. The role of …

Myriad branches in the tree of life are intertwined through ecological relationships.
Biologists have long hypothesized that intimate symbioses between lineages can influence …

Coevolution, reciprocal adaptation between two or more taxa, is commonly invoked as a
primary mechanism responsible for generating much of Earth’s biodiversity. This conceptually …

Species interactions are responsible for many key mechanisms that govern the dynamics of
ecological communities. Variation in the way interactions are organized among species …

Biodiversity loss is a hallmark of our times, but predicting its consequences is challenging.
Ecological interactions form complex networks with multiple direct and indirect paths through …

acknowledges that DHH retains the right to provide a copy of the final manuscript to the NIH …

A challenge for coevolutionary theory is how different types of interaction influence the
diversification of coevolving clades. Reciprocal specialization is characteristic of certain …

A series of silsesquioxane copolymers synthesized by hydrolysis and condensation of phenyl-
and methyltrimethoxysilanes have been studied as preceramic polymers. The pyrolytic …

Premise Variation in pollen‐ovule ratios is thought to reflect the degree of pollen transfer
efficiency—the more efficient the process, the fewer pollen grains needed. Few studies have …
