Focusing on the application of wood characteristics in taxonomic and phylogenetic studies, the book explores how these features can aid in understanding relationships among species, genera, and families. It emphasizes the importance of caution when interpreting similarities, as many wood traits have evolved independently across unrelated groups. The text highlights the use of cladistic analysis to assess wood data and establish evolutionary relationships, demonstrating that certain wood structures, like storied wood, may not indicate close relationships without further phylogenetic context.

NATURAL OBJECTS is the latest volume from Pinecone Press, featuring a blend of sensual and abstract photographs of uncut men. The work combines male forms with elements from nature, emphasizing the beauty and textures of men's bodies. This luxurious book includes 213 photos and is the final installment in the Natural Man series.

This book features 213 black and white photographs of male nudes set against diverse natural landscapes, including Hawaii, South Carolina, New Mexico, and California. It focuses on timelessness by excluding man-made objects, allowing the viewer to appreciate the models in a natural context.

This book presents a retrospective collection of previously unreproduced photographs from 1986 to 2006, featuring vibrant scenes like Utah's sandstone, Hawaiian lava flows, and Yosemite waterfalls, showcasing intact male bodies in diverse types and moods against these striking backdrops.

This book is not concerned directly with wood identification, although ability to recognize the wood features discussed in the preceding chapters is essential for work in wood identification. The present chapter is concerned with how wood characters have been and can be used in taxonomic and phylogenetic studies - and also which wood characters are likely or not likely to be useful, in general. In wood identification, a match of an unknown wood with known woods is usually attempted. In systematic application of wood data, similari ties and differences among species, genera, and families are assessed ( usually, today, in terms of a cladistic analysis). One should be especially cautious in interpreting relation between taxa the woods of which have attained similar evolutionary levels. This possibility is a very real one, because so many wood features have evolved similarly in phylads that are not closely related to each other. For example, storied wood structure has been attained in a number of phylads independently. By itself storied wood structure cannot be used as an indicator of relationship between two families, but a cladogram ( using a range of phyletically reliable features) might demoo strate that two families acquired storied structure before divergence ( a synapo morphy) and thereby a strong case for relationship of the two families is made.
