Developing know-how for the improvement and sustainable management of teak genetic resources [PDF]

, 2008
The project had the following objectives: To trace and quantify genetic diversity of teak within its natural range, DNA markers were used to assay the current distribution of genetic diversity within and between populations, investigate its mating ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Self-Pollinated Types and Ecological Adaptations of the Desert Plant Gymnocarpos przewalskii

Plants
In desert plants, outcrossing is frequently limited by pollinator scarcity, leading to a certain percentage of self-fertilization. However, research on the ecological adaptations of self-fertilized seeds remains limited.

Controlled pollinations reveal self-incompatibility and inbreeding depression in the nutritionally important parkland tree, Parkia biglobosa, in Burkina Faso

Journal of Pollination Ecology, 2018
The socioeconomically important fruit tree Parkia biglobosa is becoming less abundant in the West African savannah, possibly due to poor regeneration.

An Eco‐Social Lens on Voice for Undervoiced and Unvoiced Stakeholders

Business Strategy and the Environment, EarlyView.
ABSTRACT This conceptual paper argues it is important from an ecological–social (eco‐social) whole system point of view for businesses and policymakers to take the interests of and impacts on unvoiced and undervoiced [un(der)voiced] stakeholders into consideration for both strategic and justice reasons.

Ecology and ecophysiology of subantarctic Campbell Island megaherbs : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Ecology at Massey University [PDF]

, 2000
The megaherb growth form is not common in the New Zealand flora; yet it is a distinctive feature of the flora of New Zealand's subantarctic islands, such as Campbell Island (52°33'S. 169°09'E).

The effect of the limitation of insect pollination period on the fruit set and yield of temperate-zone fruit tree species

International Journal of Horticultural Science, 2000
The duration of effective bee pollination period was limited by caging flowering branches for shorter or longer time in blooming fruit trees in a number of experiments during the past decades.

Drivers of Nature‐Related Investment Strategies Among Institutional Investors

Business Strategy and the Environment, EarlyView.
ABSTRACT Institutional investors are increasingly responding to biodiversity loss through nature‐related investment strategies. Using survey data from 557 institutional investors, this study examines the drivers of strategy selection and how biodiversity risk is integrated across investor types, sizes, and regions.
