Hide and vanish: data sets where the most parsimonious tree is known but hard to find, and their implications for tree search methods
Three different types of data sets, for which the uniquely most parsimonious tree can be known exactly but is hard to find with heuristic tree search methods, are studied. Tree searches are complicated more by the shape ...
Foraging Behaviour in Magellanic Woodpeckers Is Consistent with a Multi-Scale Assessment of Tree Quality
(Public Library Science, 2016)
Theoretical models predict that animals should make foraging decisions after assessing the quality of available habitat, but most models fail to consider the spatio-temporal scales at which animals perceive habitat ...
Cryptic interactions revisited from ecological networks: Mosses as a key link between trees and hummingbirds
1. Ecological interactions are the glue of biodiversity, structuring communities and determining their functionality. However, our knowledge about ecological interactions is usually biased against cryptic interactions ...
Nest building by monk parakeets Myiopsitta Monachus in urban parks in Buenos Aires, Argentina: Are tree species used randomly?Construcción de nidos por la Cotorra Argentina Myiopsitta monachus en parques urbanos de Buenos Aires, Argentina: ¿son usadas al azar las especies arbóreas?
(Sociedad Española de Ornitología, 2015-12)
La cotorra argentina Myiopsitta monachus es una especie invasora muy exitosa y una plaga agrícola en muchos de los países en que se encuentra establecida. El estudio de la selección de árboles nido podría ser una herramienta ...
Application of dendrogeomorphology on the study of soil sediment deposition in the stems of Guarea guidonea trees in a disturbed riparian forest in Goias state, Brazil
(IPEF-INST PESQUISAS ESTUDOS FLORESTAISPIRACICABA, 2012-03)
The sediments resulting of natural or anthropic erosion are deposited on the soil surface and around the trunks of trees occurring in riparian forests. For assessment of the erosion, tree-rings of roots and stems were ...
Tree cavity occupancy by nesting vertebrates across cavity age
(Wildlife Soc, 2018-04)
Cavity-nesting birds and mammals exhibit species-specific nest-site selection for tree characteristics and cavity dimensions. Although trees and their cavities change as they age, with trees becoming softer and cavities ...
Microhabitat use by the whip spider Heterophrynus longicornis (Amblypygi, Phrynidae) in central Amazon

Bias in tree searches and its consequences for measuring groups supports
(Oxford University Press, 2014-09)
When doing a bootstrap analysis with a single tree saved per pseudoreplicate, biased search algorithms may influence support values more than actual properties of the data set. Two methods commonly used for finding ...
TECHNICAL NOTE: VELOCITY OF ULTRASONIC WAVES IN LIVE TREES AND IN FRESHLY-FELLED LOGS
