Ultrasonido y anisotropía en madera de Thuja plicata y Acer saccharum
Maderas: Ciencia y Tecnología, 2016 La velocidad del ultrasonido en la madera y el módulo de elasticidad, siguen un patrón anisotrópico, que se infiere mediante un modelo teórico. El objetivo de la investigación fue determinar la variación de la velocidad del ultrasonido y del módulo de ...

The successional status of sugar maple (Acer saccharum), revisited [PDF]
Annals of Forest Science, 2008 Two complementary experimental designs at two contrasting scales (landscape/long term; individual tree/short term) were used for an in-depth evaluation of the successional status of sugar maple (AS: Acer saccharum Marsh.). First, forest disturbances during the 20th century and composition were mapped for two landscapes in the Du Lievre watershed of ...

Wildlife Monographs, Volume 226, Issue 1, September 2026.We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Sugar Maple and Red Maple Face-Off: Which Produces More and Sweeter Sap?
Applied SciencesAmong the species used for syrup production, sugar maple (Acer saccharum Marsh.) is preferred by producers, while red maple (Acer rubrum L.) is considered less productive in terms of sap yield and sugar content.

Identifying trees most likely to die after a partial cut in sugar maple or yellow birch stands
The Forestry Chronicle, 2019 Many research findings related to tree mortality have been published since 2005, and it is now possible to assess postselection cut tree mortality risks in maple or softwood/yellow birch forest stands.

Conspecific Negative Distance‐Dependence and New Zealand Podocarp Forest Dynamics
Austral Ecology, Volume 51, Issue 9, September 2026.ABSTRACT The Janzen‐Connell hypothesis proposed that conspecific negative density or distance dependence (CNDDD) helps maintain the species richness of tropical rainforests through the action of specialist natural enemies that suppress conspecific recruitment beneath canopy trees.

Journal of Biogeography, Volume 53, Issue 9, September 2026.ABSTRACT Aim Northern populations of temperate tree species evolve under climatic, topographic and edaphic conditions that approach the limits of their ecological tolerance. However, the environmental constraints acting on species abundance are not spatially uniform, and their relative importance can shift markedly from core to northern populations. We

cpDNA of Acer saccharum and Acer nigrum are Very Similar [PDF]
, 1997 Author Institution: Wright State University, Department of Biological SciencesThe number of species and sub-species that comprise North American sugar maples has remained in dispute since their first characterization over 100 years ago.

Plant Biotechnology Journal, Volume 24, Issue 9, Page 5013-5040, September 2026.ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...
