Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

Ibis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

Growth of Cut-Grafting Robusta Coffee Seeds Utilizing Orthotropic and Plagiotropic Rootstocks with Application Bacillus and Pseudomonas Mixture

Journal of Applied Agricultural Science and Technology
Vegetative propagation by cut-grafting has the advantage of being able to obtain seeds that inherit two superior traits from two scion clones in a relatively short time.

The characteristics of the complete chloroplast genome for Eucalyptus robusta (Myrtaceae)

Mitochondrial DNA. Part B. Resources, 2021
Eucalyptus robusta is a great tree of Myrtaceae. It is mainly distributed in Southeast provinces of China and Southeast Asian countries. There is no study on the genome of E. robusta far. Here we report the complete chloroplast genome of E.

PERFORMANCE AND BEHAVIOUR OF CHICKENS WITH DIFFERENT GROWING RATE REARED ACCORDING TO THE ORGANIC SYSTEM [PDF]

, 2003
The performance and the behaviour of three different chicken strains, reared according to the EEC-Regulation 1804/1999 organic system, were compared. The strains had very slow (Robusta maculata), slow (Kabir) and fast (Ross) growing rates, respectively ...

Rural Capitalists and Development in Colonial Africa: A Comparative Analysis

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper explores the emergence and role of rural capitalists in colonial Sub‐Saharan Africa by comparing three peasant‐based economies: Bechuanaland, the Gold Coast and Tanganyika. Using social tables, we estimate the population and income shares of better earning agricultural producers and assess their impact on rural inequality and ...

Associated bacteria affect sexual reproduction by altering gene expression and metabolic processes in a biofilm inhabiting diatom [PDF]

, 2019
Diatoms are unicellular algae with a fundamental role in global biogeochemical cycles as major primary producers at the base of aquatic food webs. In recent years, chemical communication between diatoms and associated bacteria has emerged as a key factor

Improved mesophyll–bundle sheath connectivity is achieved via different mechanisms in C2 vs C4 Alternanthera

New Phytologist, EarlyView.
Leaf anatomy and biochemistry of C3, C2, and C4 plants. Summary Connectivity between mesophyll (M) and bundle sheath (BS) cells must improve during the evolution of C4 photosynthesis to facilitate large metabolite fluxes between these cell types, but the trait combinations that enhance M–BS connectivity and the points at which these enhancements occur ...

The Effect of Extraction Time Variation on Caffeine Content in Robusta Coffee Extract using Ultrasound-Assisted Extraction Method

Journal of Food and Pharmaceutical Sciences
West Lampung Robusta coffee has a higher caffeine content than other types of coffee. The variations in extraction time in ultrasound-assisted extraction (UAE) produced different caffeine contents than conventional extraction methods.

Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

Plant, Cell &Environment, EarlyView.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...
