Alterations induced by Tortrimosaica polypodivora on the stems of Microgramma vacciniifolia: simple or complex galls?

open access: yesRodriguésia, 2023
Microgramma vacciniifolia, an epiphyte fern, hosts of two stem galls. One is induced by Tortrimosaica polypodivora (Lepidoptera), which can also induce galls in M. squamulosa and M. mortoniana. The alterations induced by T.

Gall's Visit to The Netherlands [PDF]

open access: yesJournal of the History of the Neurosciences, 2011
In March 1805, Franz Joseph Gall left Vienna to start what has become known as his cranioscopic tour. He traveled through Germany, Denmark, and The Netherlands. In this article, we will describe his visit to The Netherlands in greater detail, as it has not yet received due attention.

Comparison of Galled Trees [PDF]

open access: yesIEEE/ACM Transactions on Computational Biology and Bioinformatics, 2011
Galled trees, directed acyclic graphs that model evolutionary histories with isolated hybridization events, have become very popular due to both their biological significance and the existence of polynomial time algorithms for their reconstruction. In this paper we establish to which extent several distance measures for the comparison of evolutionary ...

All that glisters is not galled [PDF]

open access: yesMathematical Biosciences, 2009
Galled trees, evolutionary networks with isolated reticulation cycles, have appeared under several slightly different definitions in the literature. In this paper we establish the actual relationships between the main four such alternative definitions: namely, the original galled trees, level-1 networks, nested networks with nesting depth 1, and ...
