Insights to the host range of the flea beetle Disonycha argentinensis Jacoby, 1992 (Coleoptera:Chrysomelidae), a candidate biological control agent of alligator weed in the U.S.A.
ABSTRACT.- Alligator weed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae) is an aggressive invader in waterways and pastures throughout most of the southeastern U.S.A., and California. Three insect biological control agents have provided substantial control of aquatic A. philoxeroides in the warmer parts of its range in the U.S.A. However, these insects are less effective against A. philoxeroides in riparian-terrestrial habitats.
Nutrient addition to a subtropical rangeland:effects on animal productivity, trophic efficiency, and temporal stability.
ABSTRACT.- A comprehensive understanding of how native grasslands (rangelands) respond to chronic nutrient addition requires considering interactions with climate variability, water availability in particular, and with stocking rate management. We assessed animal production responses to phosphorus plus nitrogen fertilization sustained over a decade on a highly diverse subtropical grassland. ©2024 The Society for Range Management.

Equine chorionic gonadotropin (eCG) treatment in heifers:Double ovulation, twinning rate, and pregnancy losses in twin pregnancies.
ABSTRACT.- This study aimed to evaluate the effects of different doses of equine chorionic gonadotropin (eCG; 200 and 300 IU) administered at the end of a fixed-time artificial insemination (FTAI) treatment protocol on ovulation, pregnancy, and twin rates in Bos taurus beef heifers. In addition, pregnancy losses in heifers with singleton and twin pregnancies were determined.
CRONOSOJA:a daily time-step hierarchical model predicting soybean development across maturity groups in the Southern Cone.
ABSTRACT.- Accurate prediction of phenology is the most critical aspect for the development of models aimed at estimating seed yield, particularly in species that exhibit variable sensitivity to environmental factors throughout the cycle and among genotypes. With this purpose, we evaluated the phenology of 34 soybean varieties in field experiments located in Argentina, Uruguay and Paraguay.
