Lumbricus terrestris L. (1758) is an earthworm which has been studied in some detail with
respect to the soil environment. Research has been undertaken on interactions of this species
with other soil dwelling organisms, but little has taken place on intraspecific interactions of L.
terrestris (Lowe and Butt, 2002, Grigoropoulou et.al., in press) particularly between differently
aged earthworms (specifically adults and hatchlings) and their environment.
This work reports an experiment set up to investigate interactions of L. terrestris hatchlings with
adults and their burrow systems under controlled laboratory conditions in Evans? boxes (0.8 x
0.2 x 0.008 m). Two treatments were inoculated with adult L. terrestris (1 individual/box) and
cultured at 17oC for 2 months. Thereafter, adults were removed from one treatment and hatchlings
(1/box) were added to all boxes in three treatments (n = 8 replicates).
1. In the presence of the adult (ABH);
2. In the absence of an adult but the presence of a fully constructed burrow (BH); and
3. In the absence of both adult and burrow system (H).
Boxes were monitored weekly and burrowing activities and position within the burrow system of
adults and hatchlings were recorded throughout the experiment. Three months after hatchling
addition the experiment was terminated and masses recorded.
The proportion of hatchlings observed occupying adult burrows was significantly different in the
ABH and BH treatments at 47.5 % and 75.4 % respectively. At termination of the experiment,
survivorship of adults and hatchlings was 87.5% in the ABH and 100% in BH and H treatments.
Mean (±S.D.) mass of hatchlings differed significantly among treatments (p<0.05) and was
greater in the hatchling alone treatment (H) (4.04 ± 0.39 g), compared with the BH (3.09 ± 0.93
g) and ABH treatments (2.13 ± 0.64 g).
Results from this and previous laboratory experiments (Grigoropoulou et. al., in press) suggest
a negative influence of both the presence of adult and its burrow system on hatchling growth.
Further investigation is required to examine how an inherited environment (i.e. burrow) might
negatively affect growth of hatchlings. MenosLumbricus terrestris L. (1758) is an earthworm which has been studied in some detail with
