Impact Of Grazing Pressure On The Plant Population Dynamics Of Heterpogon Contortus (Black Speargrass) In Subtropical Queensland, D M. Orr, C J. Paton

IGC Proceedings (1977-2023)

Heteropogon contortus is a palatable pasture grass which is being threatened by , increases in grazing pressure, particularly during drought. This paper presents interim results plant population dynamics of H. contortus., as affected by stoc.1s tak. legume augmentation (mainly Stylosanthes sabra cv. Seca) and p1 Jvision of a dry-season supplement for cattle. The study began in 1%8. By 1991, basal ara of H. co11tortus was highest at the light .. Jt stocking rate of 0.187 steers/ha and declined linearly to be longest at the heaviest stocking rate of 0,5 steers/ha. Similarly, survival of the H. contortus tussocks initially present …

Seca Stylo (Stylosanthes Scabra Cv. Seca) Populations Increase Faster Under Light Grazing, D M. Orr, C J. Paton

IGC Proceedings (1977-2023)

Augmentation of native pastures with legumes such as Stylosanthes scabra can increase cattle live-weight gain relative to that from native pasture. In the longer term, however, Stylosanthes spp, density can increase and populations of native grasses may become unstable. This paper reports interim results from a study aimed al monitoring changes in the density of S. scabra cv. Seca in relation to stocking rates, The density of Seca monitored in permanent quadrats increased from 15 plants/m2 in 1988 to 100 and 25 plants/m2 in 1992 at 0.25 and 0.5 beasts/ha respectively. These increases resulted from both the survival of the …

IGC Proceedings (1977-2023)

This paper describes some of the studies that have been conducted since 1985 to develop clover-based pasture systems for intensive sheep production in the central highlands of Papua New Guinea. The clovers tested were Trifolium repens cv. Haifn (Haifa white clover) and Trifolium semipilosum cv. Safari (Kenya white clover). They were sown together, with setaria (Setaria sphacelata cv. Nandi) and signal grass (Brachiaria decumbens cv. Basilisk) at Menifo (1400 m asl) and with setacia and kikuyu (Pennisetum clandestinum cv. Whittet) at Tambul (2240 m) and Yogos (1950 m) in the central highlands. At Menifo, when rotationally grazed …

An Integrated Approach To Soil-Plat-Animal Interactions On Grazed Legume-Based Pastures On Tropical Acid Soils, M J. Fisher, C E. Lascano, R J. Thomas, M A. Ayarza, I M. Rao, G Rippstein, J.H M. Thornley

IGC Proceedings (1977-2023)

Legume-based pastures developed by the Tropical Pastures Program (TPP) of CIAT give spectacular increases in both stocking rates and animal live-weight gains on the savannas of Latin America, A team within the TPP is addressing the problems of their management for legume persistence and soil-plant-animal interactions, using as Its focus a grazing experiment on 2 oxisols of contrasting texture on the Colombian Llanos. The objective is to model the pastures to forecast the effect of management options on long-term persistence and nutrient cycling in grazed legume•grass associations in the Latin American savannas.

Persistence Of Roundleaf Cassia In Grazed Pastures - A Conceptual Model, R M. Jones, C K. Mcdonald, G A. Bunch

IGC Proceedings (1977-2023)

Roundleaf cassia (Cassia rotudifolla) cv. Wynn is a short-lived perennial that relies on seedling recruitment for long-term persistence. Its persistence is considered in terms of survival of plants from the initial sowing, seed set, seedling recruitment, run-down of reserves of soil seed, and survival of seedlings. The major factor controlling all these stages is soil moisture stress; grazing management 'is less important. A conceptual model of Wynn persistence is presented and progress in mathematical modeiling is reported.·

Variation In Hydrological Characteristics Of The Soils Associated With Grazed Patches In Granitic Landscapes In Northern Australia, M M. Sallaway, D Waters, B Bridge, F P. Wandera

IGC Proceedings (1977-2023)

Under medium to heavy grazing of black speargrass (Heteropogon contortus) landscapes of south-east Queensland, "patchiness" has developed with a change from H. contortus to Aristida spp., Cllrysopogo11 spp. or a,inual grasses. This grazed patch development is associated with changes in soil hydrological characteristics which in turn affect runoff and soil erosion. T!\e soil hydrologic properties were studied using a rainfall simulator and disc permeameter. The remnant H. contortus areas had higher infiltration characteristics mainly due to the maintenance of larger mncropores (1-3 mm). In the Arlstida patches, the contribution of those large macropores has been greatly reduced. Th is effect …

Limitations of low-quality grass pastures, soil fertility, mechanisms of legume persistence and the long-term sustainability of pastures for beef production were studied in a humid subtropical environment of New South Wales, Australia. Sustainability of pastures and animal growth responses in 3 experiments (varying from 4 to 10 years' duration) al 2 sites have been analysed and described. Steers or heifers were used lo assess the effects of introducing subtropical or temperate legumes, level of superphosphate and stocking rate on natural grass pastures, Principal factors which improved the level of beef production from pasture were (i) introducing persistent legumes (ii) level …

Bothriochloa Pertusa- A Useful Grazing-Tolerant Grass For The Seasonally Dry Tropics?, R J. Jones, A Kerr

IGC Proceedings (1977-2023)

Data from 2 grazing experiments, small-plot studies, and a vegetation and soil survey showed that Bothriochloa pertusa increased relative to native tufted perennial grasses under heavy grazing pressure and was adapted to a wide range of soils in the 500-1000 mm zone of northern Australia. Ability to grow on low-P soils, lower relative palatability, strong stoloniferous development and good seed production, were features of its success. Annual steer gains on 8. pertusa pastures were similar to those on native pastures, with no species x stocking rate interaction. Steer gains on B. pertusa-Vernno stylo pastures were lower than on Urochloa …

Sustainability Of Sown Pastures In The Tropics And Subtropics, Jose M. Toledo, Daniel Formoso

IGC Proceedings (1977-2023)

Sown pastures in the tropics and subtropics are important components of production systems. Their role in and contribution to land productivity and economic development are well understood; however, their roles in sustainability and environmental protection are rather misunderstood and little known. The main constraints to sustainability of sown pastures fall into two categories: physical, biological and technical constraints include soil and climatic limitations, lack of adaptation of plants to physical and biotic stress and the limitations of farmers or ranchers to apply technology; socioeconomic factors include political instability, poorness of society and the market forces for land, inputs and products. …

Stability In Rangelands: Ecology And Economics, B H. Walker

IGC Proceedings (1977-2023)

Examples of changes in rangelands are presented relating to changes in livestock number, plant species. composition and soil changes (associated with changes in production), The mechanisms Involved are described, using examples, under the headings: event-driven change, threshold effects, non-linear and hysteresis effects, effects of spatial variation, significance of temporal variation, and interactive effects. The implications for management are presented in the form of a proposed optimal control model which maximises a complex function of welfnre based on long-term net economic benefit, in which stocking rate effects on the state of the rangeland feed back on to economic return.

Journal of Contemporary Water Research and Education

In developing countries in Africa and Asia, meeting challenges of water scarcity and pollution has often been hampered by shortcomings in higher education, including insufficient research productivity and funding, lack of opportunity for university graduates, and a mismatch between university activities and societal needs. To address these issues, we developed novel programs integrating technical instruction and preparation for professional practice in hydrology for cohorts of graduate students from Morocco and Egypt (2012–2013) and from Türkiye and Indonesia (2013–2014). Students participated in an initial online course and a follow-up workshop featuring geographic information systems (GIS), remote sensing, and hydrologic modeling with …

Making Science-Inquiry Learning Accessible For Students With Complex Support Needs, Sarah Koebley, Shawnee Wakeman, Lindsay Ruhter, David Pugalee, Meagan Karvonen

Journal of Science Education for Students with Disabilities

Inquiry learning through engagement with scientific practices has proven to be an effective instructional practice for general education students. Although students with complex support needs (CSN) are required to have access to the same grade-appropriate academic content in science as their peers without CSN, it remains a challenge for special education teachers to design instruction around student inquiry and science conceptual understanding. The 5E Science Education for Special Educators (5E-SESE) Model combines three well-established conceptual constructs (three-dimensional science standards, Universal Design for Learning [UDL], and the 5E Model) to support special educators in delivering quality science instruction. With the 5E …

'Atiqot

The enclosure of the Temple Mount has the potential to provide answers to key questions concerning the development of rituals in Jerusalem. However, issues of management, control and politics have always had a crucial influence on the possibility of conducting historical and archaeological research at the site. This article attempts to analyze archaeologically the observations made at the site during the construction works conducted during 1999–2001. It includes photographs, plans and sections of the antiquities exposed at the time of those building activities.

Survey And Salvage Excavations On The Menashe Spur, Near Ḥorbat Bareqet And Kibbutz Regavim (Hebrew, Pp. 83–107; English Summary, Pp. 59–61), Amir Gorzalczany

'Atiqot

A large area, located in the catchment basin of Naḥal ‘Ada, was surveyed and consequently excavated, revealing a large number of walls and installations. Among the installations are many stone heaps and square towers. A trapezoidal enclosure was examined and partly excavated; it was most likely used to store agricultural produce. The remains in this area are probably part of an Iron Age satellite settlement, under the aegis of the city of Dor. The enclosures located in the area were dated to the Roman and Byzantine periods, and were possibly connected with the city of Caesarea. During the Islamic period …

'Atiqot

The remains of 51 individuals were recovered from a Byzantine-period tomb at Naḥalat Ahim: 47% were adults, 40% were sub-adults and 4% were between 6–12 months; no neonates were identified. There was no discernible demographic pattern regarding age, sex or place of burial within the tomb. Two benign bone tumors were found in two different individuals; both types are previously unreported in excavations in Israel.

Results Of Three Small Excavations At Nahf, Upper Galilee (Pp. 87–101), Howard Smithline

'Atiqot

The village of Nahf is located north of Karmi’el, on the lower southern slope of the Mount Meron Massif. The three areas excavated revealed occupational levels from Early Bronze Age IB, Early Bronze Age II, Middle Bronze Age II, Iron Age I–II and the Persian period. Large quantities of Hellenistic-period potsherds, including many storage vessels and a stamped Rhodian amphora handle, point to the site’s important role as a commercial center for the production of oil and wine during this period. The Hellenistic settlement ceased to exist during the second half of the second century BCE, probably following the Hasmonean …

Excavations At Ḥorbat Malta, Lower Galilee (Pp. 5–79), Karen Covello-Paran

'Atiqot

Excavations at Ḥorbat Malta, located in the Nazareth Hills, exposed evidence of occupation dating to Middle Bronze Age II (potsherds), Iron Age II and the Persian and Roman periods. The Iron II occupation included a massive fortification wall and many rock-hewn installations, including channels, grinding and pounding stones and possibly, winepresses (Area A), as well as a four-room house (Area C). The Iron Age settlement reveals intra-site planning, familiar from other contemporary sites in the central hill region. The architectural elements of the Persian period are chiefly of a domestic nature, including stone buildings, numerous rock-hewn installations (Area B), pits …
