The three instant dark teas were produced from instant green tea (IGT) by liquid-state fermentations using the microorganisms Eurotium cristatum (EFT), Aspergillus niger (AFT), and sequential inoculat...
Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach
base-age invariant approach Chapman-Richards function global parameters tree-specific parameters iterative nested regression National Forest Inventory
2017/6/26
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
Different Coefficients and Exponents for Metabolic Body Weight in a Model to Estimate Individual Feed Intake for Growing-finishing Pigs
Feed Consumption Group-housing Growth Performance Maintenance Energy Swine
2016/12/28
Estimation of feed intake (FI) for individual animals within a pen is needed in situations where more than one animal share a feeder during feeding trials. A partitioning method (PM) was previously pu...
Tropical Forest Fragmentation Affects Floral Visitors but Not the Structure of Individual Based Palm-Pollinator Networks
Tropical Forest Fragmentation Visitors
2015/11/13
Deforestation is the major cause of fragmentation and spatial isolation of populations in the
tropics [1], with potential to increase species or population extinction rates [1,2]. Despite the
import...
