Predation on Artificial Caterpillars Varies With Vertical Stratification but Not Light Gradients in a Sugar Maple Temperate Forest

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

QUATERNARY HISTORY OF FAG US IN THE ITALIAN PENINSULA [PDF]

open access: yes, 1998
The Upper Pleistocene and Holocene history of the genus Fagus in Italy is reviewed. Fagus was present in central Italy during the last interglacial (Eemian), when it was virtually absent from the rest of Europe, markedly expanded in the following forest ...

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

Population structure of Fagus grandifolia subsp. mexicana in the cloud forest of Hidalgo State, Mexico

open access: yesBotan‪ical Sciences, 2016
The highest densities and largest areas of Fagus grandifolia subsp. mexicana in Mexico grow in the cloud forest of the state of Hidalgo. Although this taxon is endangered, there is little information about its population structure.

Does shade improve light interception efficiency? A comparison among seedlings from shade-tolerant and -intolerant temperate deciduous tree species [PDF]

open access: yes, 2006
• Here, we tested two hypotheses: shading increases light interception efficiency (LIE) of broadleaved tree seedlings, and shade-tolerant species exhibit larger LIEs than do shade-intolerant ones.

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Of beta diversity, variance, evenness, and dissimilarity [PDF]

open access: yes, 2017
The amount of variation in species composition among sampling units or beta diversity has become a primary tool for connecting the spatial structure of species assemblages to ecological processes.

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

open access: yesJournal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

MICROPROPAGATION OF Fagus spp.

open access: yes, 2003
619 pp. The genus Fagus, a member of the Fagaceae family, comprises ten species of monrecious trees native to the Northern Hemisphere Temperate Zone regions of Eurasia and Eastern North America. The name Fagus (related to Greek phagein, to eat) is a reference to the distinctive triangular nuts of these species, which are eaten by ...
