Science and international nature conservation por Sayer, Jeffrey A.

“…International programs now have ambitious targets set by politicians and aspire to save the world.There is a need to balance these global environmental initiatives with a set of shorter-term practical actions to maximise biodiversity conservation. Biological scientists can cooperate with other natural resource specialists and social scientists in defining more targeted cost-effective nature conservation programs. …”

Climate finance can unlock the full potential of circular bioeconomy por Bodach, Susanne, Perera, Thinuri

“…The Circular Bioeconomy (CBE) provides a critical solution to climate change and resource scarcity by shifting from a linear to a circular model that reuses and regenerates biological materials. This approach reduces greenhouse gas (GHG) emissions through methods like converting organic waste into bioenergy and fertilizers. …”

Eucalypt plantations por Turnbull, J.W.

“…This paper reviews the historical development of the use of the eucalypt over 200 years, from its curiosity status in the botanical gardens of Europe to its extensive use as a fuelwood for the wood-burning locomotives of the national railway systems, and then to its more recent use as a major source of biomass for paper pulp, fiberboard, industrial carcoal, and fuelwood. Ecological and biological aspects of the genus Eucalyptus have made it successful as an exotic in industrial monocultures and as a multipurpose tree of benefit to small landholders. …”

Network and biosignature analysis for the integration of transcriptomic and metabolomic data to characterize leaf senescence process in sunflower por Moschen, Sebastian Nicolas, Higgins, Janet, Di Rienzo, Julio A., Heinz, Ruth Amelia, Paniego, Norma Beatriz, Fernandez, Paula Del Carmen

“…In recent years, high throughput technologies have led to an increase of datasets from omics disciplines allowing the understanding of the complex regulatory networks associated with biological processes. Leaf senescence is a complex mechanism controlled by multiple genetic and environmental variables, which has a strong impact on crop yield. …”

Condensed tannins in tropical legume fodder trees; characterisation, and interactions with rumen microbes, feed, and endogenous proteins. por Kariuki, I.W.

“…An extensive review of the literature on the chemistry and biological activity of condensed tannins (Chapter 1 and 2) revealed some significant gaps in knowledge of these processes, and the following experimental program was designed to investigate some specific aspects of the chemical and biological effects of condensed tannins (CT) in animals fed CT-containing diets. …”
