Abstract:
Leaf area relationships are important physiologically and ecologically but are not well studied in baldcypress (Taxodium distichum (L.) Rich. var. distichum). Tree leaf area (LA) and leaf area index (LAI) were measured in a wetland in southern Louisiana by dissecting crowns of felled trees and by scaling stand-level measurements with allometry. Branchlet morphology ranged from flat and open with high specific leaf area (87.2 ± 30.7 cm2·g−1; mean ± SD) to scaled with appressed leaves and low specific leaf area (22.1 ± 11.6 cm2·g−1). Leaves were more appressed higher in the canopy. Tree LA was strongly related to sapwood basal area (SBA), and SBA was related to diameter; these allometric relationships enabled estimating LA from diameters. At the plot level, LAI estimated by allometric relationship (ranging from 1.8 to 10.2) was not linearly related to output from an optical canopy analyzer measuring light extinction; ratios of allometric to optical methods were 0.8 for the sparsest plot and 2.4 for the densest plot. LAI was less in deeper flooded plots (3.6 ± 0.6) than in transiently flooded plots (8.4 ± 0.6), but it is unclear whether this represents a difference in maximum LAI or delayed attainment of maximum LAI in lower areas.

Abstract:
The whitespotted guitarfish (Rhyncobatus Springeri) resource is an important commodity and has high economic value. This study aims to determine the growth pattern of whitespotted guitarfish landed in the PPI Sungai Kakap. This research was conducted at the PPI Sungai Kakap, Sungai Kakap District, Kubu Raya Regency, West Kalimantan Province in July and August 2019. Data was collected by observation, surveys, and interviews. Data analysis of sex ratios, length, and weight was carried out on samples of whitespotted guitarfish. The results of the analysis of the sex ratio of male and female whitespotted guitarfish were 1.00:1.44, this shows that the number of male fish caught is relatively equal to the number of female fish caught. The results of the analysis of the length and weight relationship of whitespotted guitarfish, the a value is 20.643 and the b value is 0.6770. That value represents a negative allometric growth pattern for male and female fish. The negative allometrics explain that the length growth is faster than the weight growth. Generally, the increase of the length and weight is equal, but the whitespotted guitarfish has length growth faster than weight growth

Abstract:
Global warming that causes climate change is due to increased emissions of greenhouse gases (GHG) in the form of CO2, CH4 and other forms in the atmosphere. The application of the agroforestry system is one of the efforts to overcome the need for agricultural land by maintaining the function of the forest and the environment. The purpose of this study was to determine the potential for carbon stored in Arabica coffee (Coffea arabica) stands and to determine abiotic factors in the locations where Arabica coffee (Coffea arabica) stands grow in agroforestry areas. This research used descriptive method and coffee stand sampling technique using non-destructive purposive sampling. For each stand sample, 25 trees were taken for each Gayo 1, p88 and Ateng coffee varieties so that the total sample size was 75 trees. Calculation data analysis includes allometric Ketterings dry weight = 0.11 D2.62 (2001) and Arifin allometric formula = 0.281 D2.0635 (2001). Analysis of biomass data carbon = dry weight x 0.47. The results showed that the largest carbon storage was found in the Gayo 1 variety, then the p88 variety and the smallest carbon storage was found in the Ateng variety. Abiotic factors in coffee agroforestry show soil moisture 18.3%, air humidity 60-75%, soil pH 7.5%, soil temperature 21°C, air temperature 21-25°C with an altitude of 900-1100 masl. Abiotic factors affect plant growth, and light intensity also affects plant biomass.Keywords: Agroforestry, Allometrics, Abiotic Factors, Carbon, Coffee VarietiesABSTRAKPemanasan global yang menimbulkan perubahan iklim dikarenakan meningkatnya emisi gas rumah kaca (GRK) dalam bentuk CO2, CH4dan bentuk lainnyadi atmosfer.

Abstract:
To understand the effects of anthropogenic disturbance on the nutritional health of animals, it is important to measure and understand the morphometrics, allometrics, and body condition of the species. We examined the body shape, allometric relationships, and body condition of short-finned pilot whales (Globicephala macrorhynchus) in three locations across the North Atlantic. Using unmanned aerial vehicles, the body length (BL) and width (along the body axis) were measured from photographs of the dorsal side, while body height (dorso-ventral distance) was measured on the lateral side. Seventy-seven pilot whales were measured (mean±SD), including 9 calves (BL 2.37 m ± 0.118), 31 juveniles (2.90 m ± 0.183), and 37 adults (3.72 m ± 0.440). The body shape was similar among reproductive classes, with the widest point being anterior of the dorsal fin (at 30–35% BL from the rostrum). The cross-sectional body shape of the whales was flattened in the lateral plane, which increased towards the peduncle and fluke. The rostrum-blowhole distance and fluke width increased linearly with BL. The estimated volumes of pilot whales ranged between 0.15 and 0.32 m3 for calves, 0.25 and 0.64 m3 for juveniles, and 0.46 and 1.13 m3 for adults. The body condition (residual of log-volume vs. log-length) ranged from −34.8 to +52.4%. There was no difference in body condition among reproductive classes or locations.

Abstract:
This thesis examines the effects of species, rainfall and soil type on tree biomass regressions, as well as the effects of stand dominance and structure on stand biomass regressions in north-east Australian woodlands. This was achieved by examining tree characteristics and biomass relationships for a series of woodland monitoring sites throughout the study area. This study utilised a modified data set from this permanent monitoring site network to provide structural attributes for trees and communities of varying composition in the grazed woodlands. These data were supplemented with environmental data and tree harvest data sets. Initially, the research reported in this thesis developed allometric and stand biomass regressions for Callitris glaucophylla communities. This research also demonstrated that changes in tree-form were not reflected in changes in the environment, nor did such changes reflect changes in tree biomass regressions for three eucalypt species. As a result, a common regression provides a robust estimate of total aboveground biomass of eucalypt trees in the study area. Thus expensive destructive harvesting can generally be avoided for minor eucalypt species. Finally, this study demonstrated a successful methodology that described the stand structure of all the grazed woodland sites based on tree heights. This methodology was developed to allow the expansion of a single stand regression to estimate stand biomass across the entire north-east Australian woodlands. The findings demonstrated in this study, combined with the long-term data from the permanent monitoring network sites, should enhance the estimation of carbon flux within eucalypt communities of north-east Australia’s grazed woodlands.

Abstract:
Various modified methods have been proposed in response to criticisms regarding the practical applicability of allometric scaling, which is one of the most widely used approaches in predicting human drug clearance based on data from animal species. The major problems encountered among allometric methods in predicting human drug clearance are addressed in this dissertation. In chapter 2, a large data set for allometric scaling (n = 138) was collected from the literature and was categorized according to the following criteria: oral or systemic clearance; elimination routes; protein or non-protein chemicals; low, intermediate, or high metabolic clearance. Some significant observations have been made regarding the applicability of allometric scaling according to the pharmacokinetic and physical-chemical properties of the drugs examined. Of special note, several potential rules were developed for when one could expect large vertical allometry. In chapter 3, a new model for predicting human clearance was developed. The new model was shown to provide better predictability than any other current approach. In particular, the new model for the first time predicts the occurrence of large vertical allometry noted in humans. In chapter 4, a general equation was derived, which directly describes the mathematical relationship between predicted pharmacokinetic (PK) parameters in humans and the body weights of animals and the values of their corresponding measured PK parameters. This relationship clearly illustrates the species or body weight-dependency of the prediction performance by allometric scaling. Finally, real data from the literature demonstrated the species-dependency predicted from the equation. In chapter 5, the functionality of the correction factors, maximum life-span potential (MLP) and brain weight (BrW) in allometry is mathematically described for the first time. It was found that corrections by MLP or BrW are equivalent to a multiplication of certain constants by the predicted values in humans from simple allometry and has nothing to do with any measured values of PK parameters in any animal species. The role of correction factors (MLP and BrW) or "rule of exponents" in species scaling was evaluated.

Allometric scaling was found as a plausible technique for dose determination in children. Permeability and P-glycoprotein efflux transport of antimalarials were determined using in-vitro Caco-2 cells. Mefloquine showed P-glycoprotein inhibition. Amodiaquine, artesunate and artemisone were not P-glycoprotein substrates or inhibitors. Methylene-blue showed some P-glycoprotein mediated efflux. Permeability was high for amodiaquine and artemisone, medium for mefloquine and artesunate and low for methylene-blue. P-glycoprotein was up-regulated when exposed to dihydroartemisinin/artemisone in combinations with amodiaquine/mefloquine.

Abstract:
Stem diameter at breast height (D1.3m) and tree height (H) are commonly used measures of tree growth. Based on correlation analysis between biomass of stem, branches and leaves and stem diameter and height of tree we can identify allometric equation for predicting biomass and carbon sequestration of the vegetation. This study was carried out in the natural forests of Me Linh Station for biodiversity to develop allometric equation between biomass and diameter at breast height and height of tree. The study results indicated that twenty tree species dominate in natural forests in Me Linh Station for Biodiversity and they were selected for sampling. Through the 80 established linear equation models for above and below –ground biomass (AGB and BGB), we found that the biomass of tree species in Me Linh Station for Biodiversity were closely correlated with the diameter factor (R>0.902) and not clearly correlated with the height (correlation coefficient = 0.5498, R2< 0.549). Four regression equations were established, including: Pstem = 25.3051*(D1.3m)0.4627 (R2 : 9.661); Pbranch = 12.1043*( D1.3m)0.5416 (R2 : 9.8); Pleaves = 9.446*(D1.3m)0.5976 (R2 : 0.9363); P total biomass of forest = 25.882*D1.725 with R2: 0.8561) for estimating biomass and carbon sequestration of natural forest at the research site.

ENGLISH ABSTRACT: The ostrich industry has overcome many challenges since it originated. However, it is still vulnerable to sudden changes in customer preferences and economic cycles. As feed costs are the greatest expense in ostrich production, optimising feed formulations is vital. This will be possible if the growth and development of the ostrich can be simulated by modelling software. Various studies were conducted to describe ostrich growth in the form of equations that can be used in modelling software to increase the accuracy of predictions. In the first study, birds were given the choice of four diets with varying energy (8.5 or 13.5 MJ ME/kg feed) and protein (180 or 120 g/kg feed) levels. The birds preferred the high density diet (high energy and protein) in each growth phase. A growth curve of assumed optimal growth was constructed. The chemical fractions of the body were shown to increase non-linearly with advancing age and equations were established to predict the change of the body composition over time. In the second trial, birds received a formulated growth diet and were fed according to their nutrient requirements. Growth data was collected on the separate body components of maturing birds. Feather and skin nodule growth was defined for birds hatched in the summer. Allometric equations were set up to determine, predict and model the ostrich skin size and skin weight, some bones, some organs and the commercially valuable muscles through the growth cycle. The final trial was conducted to determine the effect of diet density (energy and amino acid level) on the growth of ostrich body components. A four-stage, 3 x 5 (energy x protein) factorial design was developed with varying energy and protein feeding regimes. Protein (amino acid) level had no influence on body component growth. Energy level had no effect on feather growth, skin nodule growth, bone and organ growth and muscle growth. Increased levels of dietary energy increased the skin size and skin weight. Increasing the dietary energy level also had a significant effect on the total body fat of the birds. Allometric equations were set up for each variable to predict the effect of diet on ostrich growth. Results in this study provide a framework for simulation modelling. Predicting ostrich growth and development is paramount to accurate diet formulations and lower feeding costs.
AFRIKAANSE OPSOMMING: Die volstruisindustrie het reeds vele struikelblokke oorkom, maar bly steeds kwesbaar vir skielike veranderinge in die ekonomiese klimaat asook in die voorkeure van die verbruiker. Een van die belangrikste insetkostes in volstruisproduksie is voer en daarom is dit noodsaaklik om voerformulerings te optimiseer. Die doel van hierdie tesis was om by te dra tot die ontwikkeling van modellering sagteware wat die groei en ontwikkeling van die volstruis naboots. Die spesifieke doel was om volstruisgroei te bestudeer en te bespreek deur middel van vergelykings wat gebruik kan word om die akkuraatheid van die simulasiemodelle te verhoog. Tydens die eerste studie is die voëls die keuse van vier diëte gegee waarvan die energie- (8.5 of 13.5 MJ ME/kg voer) en proteïen- (180 of 120 g/kg voer) vlakke verskil het. Die voëls het in die hoëdigtheid voer (hoog in energie en proteïen) in elke groeifase gekies. Uit hierdie data, wat aanvaar is om optimale groei te verteenwoordig, is ‘n groeikurwe gekonstrueer wat getoon het dat die chemise komponente van die liggaam nie-linieêr toegeneem het oor tyd. Vergelykings is hieruit afgelei wat die verandering in die liggaamsamestelling oor tyd kan voorspel. In die tweede studie het die voëls ʼn vier-fase geformuleerde groeidieët ontvang en is na gelang van hulle voedings behoeftes gevoer. Groeidata is ingesamel van die individuele liggaams-komponente van die groeiende volstruise. Veer- en velgroei is gedefinieer vir die voëls wat in die somer uitgebroei het. Allometriese vergelykings is opgestel om te bepaal hoe die volstruis se velgrootte, velgewig, sekere bene en organe, asook die kommersiële belangrike spiere gedurende die groei-siklus verander. Die finale studie is uitgevoer om die effek van voedingsvlak (energie- en aminosuurvlak) op die groei van die volstruis se liggaamskomponente te bepaal. ʼn Vier-fase, 3 x 5 (energie x proteïen) faktoriale ontwerp is gebruik met veranderende energie- en proteïenvlakke. Proteïen- (aminosuur) vlakke het geen invloed op die groei van die liggaamskomponente gehad nie. Energievlak het geen effek op die veer-, vel-, velknoppie-, been-, organe- en spiergroei gehad nie. Toenemende vlakke van energie het wel gelei tot ʼn toename in die velgrootte en massa. Die toename in voedingsengergie-vlakke het ook ʼn betekenisvolle effek op die totale liggaamsvet van die voëls gehad. Allometriese vergelykings is opgestel vir elk van die veranderlikes om die effek van dieët op elke komponent van die volstruis te bepaal. Die resultate van hierdie studies verskaf ‘n raamwerk vir die simulering en modellering van die groei en ontwikkeling van die volstruis. Akkurate voorspellings van die groei en ontwikkeling van die volstruis is noodsaaklik vir akkurate dieëtformulering en verlaagde voedingskostes.
