Nitrogen Content and Dry-matter Digestibility of Guinea and Sabi Grasses as Influenced by Tree Legume Canopy [PDF]

, 2004
A research study was undertaken to study the grass layer across a mini landscape dominated by tree legume Albizia lebbeck to explore the nutritional differences of two introduced grasses, Guinea grass (Panicum maximum) and sabi grass (Urochloa ...

The efficacy and costing of termite (Blattodea: Termitoidae) survey methods in Australian tropical savannas

Austral Entomology, Volume 63, Issue 4, Page 447-456, November 2024.
Abstract Termites are important ecosystem engineers in many ecosystems globally. Hence, surveys of termite species composition, abundance and activity can be important for understanding ecosystem function—especially in biomes where they tend to be abundant, such as tropical savannas. However, comprehensively surveying termites can be challenging due to

CONTRIBUTION TO THE THEORY OF CELL COLLAPSE IN WOOD: INVESTIGATIONS WITH EUCALYPTUS REGNANS

Maderas: Ciencia y Tecnología, 2002
Total collapse is considered as the sum of "liquid tension collapse" and "stress collapse". An equation is derived giving total collapse as a linear function of wood temperature and, to a smaller extent, of collapse-free shrinkage.

Weak link or strong foundation? Vulnerability of fine root networks and stems to xylem embolism

New Phytologist, Volume 244, Issue 4, Page 1288-1302, November 2024.
Summary Resolving the position of roots in the whole‐plant hierarchy of drought‐induced xylem embolism resistance is fundamental for predicting when species become isolated from soil water resources. Published research generally suggests that roots are the most vulnerable organ of the plant vascular system, although estimates vary significantly ...

Can individual and social patterns of resource use buffer animal populations against resource decline?

, 2015
Species in many ecosystems are facing declines of key resources. If we are to understand and predict the effects of resource loss on natural populations, we need to understand whether and how the way animals use resources changes under resource decline ...

Influência da compactação do solo na produtividade da rebrota de eucalipto. [PDF]

, 2015
Normalmente, as áreas de rebrota sofrem a influência das operações de colheita, aplicação de herbicidas, adubos e resíduos, que concorrem para a compactação do solo. Em solos de texturas diferentes em áreas da Cia.

Home range and dynamic space use reveals age‐related differences in risk exposure for reintroduced parrots

Conservation Science and Practice, Volume 6, Issue 5, May 2024.
We used home range and dynamic space use analyses to understand how the spatial behavior of kākā differs between individuals and groups, and how that leads to differential exposure to risk. In this population, younger kākā had much larger home ranges which were more dynamic, leading to potentially higher risk outside of a conservation reserve in New ...

Burn Severity and Post‐Fire Weather Are Key to Predicting Time‐To‐Recover From Australian Forest Fires

Earth's Future, Volume 12, Issue 4, April 2024.
Abstract Climate change has accelerated the frequency of catastrophic wildfires; however, the drivers that control the time‐to‐recover of forests are poorly understood. We integrated remotely sensed data, climate records, and landscape features to identify the causes of variability in the time‐to‐recover of canopy leaf area in southeast Australian ...

Gene flow estimation with microsatellites in a Malagasy seed orchard of Eucalyptus grandis [PDF]

, 2003
International audienceEucalyptus grandis has a mixed-mating repro- ductive system. Malagasy Eucalyptus seed orchards were established 15 years ago with two aims both based on panmixia: open-pollinated seed production and genetic improvement. The panmixia

What did it used to look like? A case study from tall, wet mainland Mountain Ash forests prior to British invasion

Austral Ecology, Volume 49, Issue 4, April 2024.
This study investigates multiple different forms of ecological and historical evidence about what the Mountain Ash (Eucalyptus regnans) forests within the Wet and Damp Forest Ecological Vegetation Classes in Victoria were like prior to, and at the time of, the British invasion in 1788. We show that at the time of the British invasion, mainland Mountain
