Abstract: The relationship between ovulation rate (OR), liveweight at an autumn mating (LW) and changes in LW (DW) prior to mating was examined in 393 mature Corriedale ewes, in several sets of published data involving Merino and Romney Marsh ewes and their crosses with Border Leicesters, as well as Perendales and Scottish Blackfaces. Between groups OR was strongly associated with LW, but in only one study with DW. Within groups of Corriedales there was a slight association of OR with LW. Responses of OR to LW, over all breeds and crosses except Scottish Blackface, were parallel, being an increase of approximately 2% ovulation rate for each kilogramme of mean LW increase.The fact that OR was much more closely related to LW than DW, over a wide range of genotypes, indicates the ovarian response to the current plane of nutrition to be less than to the body reserve status of the ewe. This indicates that the value of "flushing" ewes over a brief period before joining is unlikely greatly to improve lambing percentages, unless ewes are initially in poor condition.The incorporation of these results in models of sheep production will require information on the general level of ovulation in the ewes and the adequacy of the diet, especially the protein content, at the time of joining. |

The Cerambycidae Oncideres impluviata (Germar, 1823) is an important insect pest for Acacia mearnsii De Wild in Southern Brazil. The damage caused by their girdling behavior reduces tree productivity, specially in the early years of plant establishment, when girdling is performed on the main trunk of trees. Here, we used a fragment of the mtDNA COI gene to analyze the genetic diversity, population structure and demography of O. impluviata in Southern Brazil, as well as to present the first hypothesis of phylogenetic relationships among species of the genus Oncideres. Our results identified five distinct haplotypes among the populations of O. impluviata, with the most common haplotype identified as O.imp_COI_01. The phylogenetic inferences corroborated the monophyly of O. impluviata with maximum statistical support. In addition, the phylogeny recovered three main population strains that are largely congruent with the haplotype network, which includes two lineages that are found in different edaphic regions of Rio Grande do Sul (Serra do Sudeste and Encosta Inferior do Nordeste). This is the first molecular phylogenetic assessment of O. impluviata. Our findings provide insights into the evolution of a significant species for the Brazilian forestry sector, as well as new resources for planning of pest management strategies. |
