RJ18070Plant litter decomposition in a semiarid rangeland of Argentina: species and defoliation effects

Mariela L. Ambrosino, Carlos A. Busso, Yanina A. Torres, Leticia S. Ithurrart, Juan M. Martínez, Gabriela Minoldo, Daniela S. Cardillo and Iris R. Palomo
pp. 371-381

Plant litter production is important in nutrient cycling and ecosystem productivity, whereas organic matter loss from litter might be affected by defoliation, and the plant canopy. Aboveground litter production by area unit was similar between three grasses; however, leaf blade decomposition rates were higher in desirable than undesirable grasses. The opposite was true for belowground litter. Moderate defoliation did not affect organic matter decomposition, and the presence of desirable grasses promoted litter decomposition, a key factor in determining soil fertility in terrestrial ecosystems.

RJ19039The role of seedbanks in invasions by Hyparrhenia hirta (L.) Stapf in Australia

Vinod K. Chejara, Paul Kristiansen, R. D. B. (Wal) Whalley, Brian M. Sindel and Christopher Nadolny
pp. 383-392

Hyparrhenia hirta (also known as Coolatai grass or thatching grass) has been recognised as a serious invasive weed in Australia since the early 1980s. Several hundred accessions of H. hirta were earlier introduced into Australia as a promising pasture plant, and almost all were discarded because of poor seed production. However, our results show that present roadside populations have a very large fecundity enabling a very large short-lived seed bank to develop beneath dense stands.

RJ19051Recovery of Pindan vegetation on seismic lines

Seismic exploration occurs throughout much of Australia, especially in central and northern regions, although the recovery of vegetation on seismic lines is rarely investigated. We measured the recovery after raised-blade clearing of Pindan vegetation, and the interaction with fire, on seismic lines in the West Kimberley. Overall, the vegetation structure recovered quickly (6–12 months); however, individual characteristics varied in their response after clearing.


Little is known about seed dispersal via Tan sheep dung on the dry grasslands of the Loess Plateau. We found that the mean seedling density was 0.72 g–1 dung. Small, round seeds are most suitable for endozoochorous dispersal. Stocking rate had no effect on the number of germinated seeds that collected from summer or winter grazing pastures. Plant seeds could disperse through sheep grazing, which is an adaptation of plants to the harsh environment of the semiarid areas.


Germination of seeds after exposure to the animal digestive tract is necessary for the digestive tract-mediated propagation of plants. The germination rate, structures (e.g. wings, wool) and characteristics (length, width, thickness) of seeds changed significantly in response to simulated digestion by grazing sheep. Digestive tract-mediated propagation increases seed dispersal, which allows plants to adapt to a changing environment.

RJ19027Combined effects of grazing and climate warming drive shrub dominance on the Tibetan Plateau

pp. 425-439

Shrub encroachment is a new threat to the unique pastoral grasslands of the Tibetan Plateau. Our model, which focuses on ecohydrological feedbacks, suggests that recent shrub encroachment may be an indirect response to climate warming via an extended growing season and the competitive escape of specific shrub species, as indicated by an advancing shrubline. Under high intensity of grazing, only herding by more browsers can prevent both shrub encroachment and the complete loss of herbaceous vegetation.

RJ19066Optimising cattle grazing distribution on rangeland: a systematic review and network analysis

Maggie L. Creamer, Leslie M. Roche 0000-0003-2954-8056, Kristina M. Horback and Tina L. Saitone
pp. 441-455

Numerous tools exist to optimise grazing patterns to overcome livestock distribution challenges. This paper surveys and categorises these tools and analyses the connectivity of existing research to identify and isolate knowledge gaps. A literature review revealed specific types of tools and strategies to improve cattle distribution, categorised as either ‘animal’ or ‘environmental manipulations’. Strategies are overwhelmingly studied in isolation, and potential exists to increase efficacy by integrating multiple strategies to achieve a desired outcome.
