Leaf expansion and leaf turnover of perennial C4 grasses growing at moderately low temperatures

Revista de la Facultad de Ciencias Agrarias, 2017
Understanding the mechanisms by which some C4 grasses grow more than others at moderately low temperatures (~12-20ºC) is valuable to select materials to lengthen the growing season.

Concentrate levels for lambs grazing on buffel grass Doses de concentrado para cordeiros mantidos em pastos de capim-bufel

Revista Ciência Agronômica, 2011
Use of concentrate for lambs grazing buffel grass may improve animal performance and animal traits. The objective of the present trial was to evaluate the final body weight, average daily gain, total weight gain and carcass traits (cold and hot carcass ...

Recent Replacement of Native Pili Grass (Heteropogon contortus) by Invasive African Grasses in the Hawaiian Islands [PDF]

, 1998
We surveyed 41 sites from throughout O'ahu that had been dominated by native pili grass (Heteropogon contortus) in the late 1960s. Pili grass was absent from 14 (35%) of those sites in 1997 and had declined in abundance in most of the 27 remaining ...

Can competition with pasture be used to manipulate bellyache bush (Jatropha gossypiifolia L.) population biology? [PDF]

, 2013
Bellyache bush (Jatropha gossypiifolia L.) is an invasive weed that poses economic and environmental problems in northern Australia. Competition between pasture and bellyache bush was examined in North Queensland using combinations of five pasture ...

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats

American Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

DNA metabarcoding provides new insight into the diet of invasive chital deer (Axis axis) in a tropical savanna landscape

Ecosphere, Volume 16, Issue 6, June 2025.
Abstract The introduction of non‐native species into new environments can cause significant ecological harm and is considered a major conservation threat. As populations of invasive species continue to establish and increase across the globe, novel methods can provide new insights into their biology and potentially aid in management.

Source population and time spent in captivity affect survival and reproduction of long‐distance translocated northern bobwhites

Animal Conservation, Volume 28, Issue 3, Page 365-379, June 2025.
Long‐distance translocations of northern bobwhites are increasingly used to access source populations with sufficient densities for translocation. This study compared the survival and productivity of bobwhites translocated from the South Texas Plains and the Floridian Coastal Plain to the Floridian Coastal Plain, revealing higher survival and fecundity
