Pontoscolex corethurus (Müller, 1857) is the most common invasive earthworm in disturbed lands in the tropics. Conditions required for its successful colonization of new plots are still not understood since some areas can be invaded while others, sometimes in the vicinity, are not. We kept newly hatched P. corethrurus in a wide range of Amazonian soils where population densities had been previously evaluated. We identified soil conditions that best sustain survival, soil ingestion and growth of P. corethrurus in controlled laboratory conditions and checked if presence/absence in the field was consistent with laboratory observations. While pH and Ca influenced survival; Mg and C content were the greatest determinants for growth and C:P, Mg and clay contents determined soil ingestion rates. Soil ingestion and growth rate were correlated. There were no differences in earthworm soil ingestion rates between invaded and non-invaded soils. However, growth rate and survival were higher in soils from invaded sites than in soils from non invaded sites, indicating that soil quality may play a role in the invasion process. We identified two cases where P. corethrurus did not occur: (1) unfavourable soil texture and chemical properties, but also some areas with and (2) favourable soil texture and chemical properties but no invasion. Other parameters, like vegetation cover (grass or trees), soil structure and compaction, soil hydrologic processes or biotic resistance of native earthworm communities could potentially also be key elements for understanding why P. corethrurus populations occur in some sites and not in others.

This study assessed two superovulatory treatments and the feasibility of transcervical embryo recovery in Lacaune ewes. Ewes (n=23) received medroxyprogesterone acetate sponges (60mg, Progespon®, Syntex, (Prolise®, Tecnopec, São Paulo, Brazil) 24 h before sponge removal and were superovulated with 133 mg of porcine FSH i.m. (Folltropin®-V; Bioniche Animal Health, Belleville, Canada) in six decreasing doses (twice daily) at 60 h before sponge removal, under a crossover design. In conclusion, both treatments showed high variability in ovulatory response which might reduce the embryo yield average from donors. The protocol for cervical relaxation allowed the transcervical embryo recovery in high percentage of Lacaune ewes. |
