Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

open access: yesOikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

Can non-timber forest products solve livelihood problems? A case study from Periyar Tiger Reserve, India [PDF]

open access: yes, 2008
Collection of non-timber forest products (NTFPs) has been promoted in India as a strategy to aid wildlife conservation whilst simultaneously alleviating poverty, and recent legislation now gives communities living within protected areas the legal right ...

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

open access: yesPeople and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Breeding habitat selection of Canada Warblers across three distinct landscapes in Québec

open access: yesAvian Conservation and Ecology
We investigated the breeding habitat selection of the Canada Warbler ( Cardellina canadensis ) in southern Quebec across three distinct landscapes: a mixed boreal forest, an agroforestry landscape, and a riverine deciduous forest.

Hydrochemical Fluxes in Bulk Precipitation, Throughfall, and Stemflow in a Mixed Evergreen and Deciduous Broadleaved Forest

open access: yes, 2019
Rainfall is one of the primary sources of chemical inputs in forest ecosystems, and the basis of forest nutrient cycling. Mixed evergreen and deciduous broadleaved forests are currently one of the most threatened ecosystems due to their sensitivity to ...

Where were all the trees? Computer vision meets landscape history to unlock the potential of historical Ordnance Survey maps

open access: yesPeople and Nature, EarlyView.
Abstract The first edition of the Ordnance Survey's 1:2500 County Series is marked with treed areas, such as woodlands and orchards, and, remarkably, freestanding trees. Consequently, it is an unparalleled source of information on the distribution of trees across Britain in the mid‐late nineteenth century, when the maps were first surveyed. In order to

The transformation of a Norway spruce dominated landscape since pre-industrial times in northern Sweden: the influence of modern forest management on forest structure

open access: yesSilva Fennica, 2009
Logging history and the study of reference conditions in Scandinavian boreal forests has tended to focus on Scots pine dominated ecosystems. This paper presents a regional study of pre-industrial forest conditions and examines the effects of the ...

Origin of Deciduous and Evergreen Habits in Temperate Forests [PDF]

open access: yesEvolution, 1966
Deciduous hardwood forests in temperate parts of the Northern Hemisphere, brilliantly colored in autumn and leafless in winter, provide a striking contrast with the somber broadleafed forests that extend to tree line in the temperate Southern Hemisphere and remain green through the year.

Turbulence structure in a deciduous forest

open access: yesBoundary-Layer Meteorology, 1988
Three-dimensional wind velocity components were measured at two levels above and at six levels within a fully-leafed deciduous forest. Greatest shear occurs in the upper 20% of the canopy, where over 70% of the foliage is concentrated. The turbulence structure inside the canopy is characterized as non-Gaussian, intermittant and highly turbulent.

Comfort in the canopy: How urban treescapes affect human thermal comfort in a temperate climate

open access: yesPeople and Nature, EarlyView.
Abstract People living in urban centres are exposed to higher levels of heat stress than those living outside of these areas; this is intensified by the urban heat island effect. Heat stress is a concern for the more vulnerable members of society and can exacerbate many medical conditions; excessive heat increases morbidity and mortality rates.
