Agriculture is a significant source of GHGs globally and ruminant livestock animals are one of the largest contributors to these emissions, responsible for an estimated 14% of GHGs (CH4 and N2O combined) worldwide. A large portion of GHG fluxes from agricultural activities is related to CH4 emissions from ruminants. techniques, artificial (e.g. SF6) or natural (e.g. CO2) tracer techniques, and micrometeorological methods using open-path lasers. Under the indirect methods, emission mechanisms are understood, where the CH4 emission potential is estimated based on the substrate characteristics and the digestibility (i.e. from volatile fatty acids). These approximate methods are useful if no direct measurement is possible. The different systems used to quantify these emission potentials are presented in this chapter. Also, CH4 from animal waste (slurry, urine, dung) is an important source: methods pertaining to measuring GHG potential from these sources are included |

Competitive interactions and environmental factors act as filters and both determine community
assembly at different scales. The description of species co-occurrence patterns through relevant
null-model analysis has been seldom addressed for soil animals in the scientific literature. In
this study, we assessed the spatial distributional features of an earthworm community and
selected soil properties in a gallery forest of the Colombian ?Llanos?. Non-parametric statistical
tools, namely Spatial Analysis Distance IndicEs (SADIE), Null-model (Co-occurrence) analysis,
and Partial Mantel test combined with multivariate analyses (correspondence and Co-Inertia
analyses) were used. Our hypotheses were: i) species of the gallery forest co-occur at shortscale
by occupying different areas of varying physico-chemical properties, and ii) the species
co-occurrence pattern is not structured by competition.
At the local scale of our study (tens of meters) earthworm species co-occurred more frequently
than expected by chance (EBC), and the C-score was significantly different to the observed
value only for one algorithm (fixed-proportional). The SADIE analyses confirmed the presence
of small patches and gaps of varying size. The number of clusters (i.e. patches or gaps) ranged
from a minimum of 2 to a maximum of 7. SADIE analysis also confirmed the randomness pattern
of the spatial distribution of species. A significant species association and dissociation was
observed for different pair of species.
The Co-Inertia analysis showed the correlation between earthworms and soil variables, and the
Partial Mantel test revealed which soil variable was significantly linked to the spatial distribution
of species, which seemed to be species-specific. Compared to other studies conducted in the
area, and where a clear opposite spatial pattern was detected for two species, there was no
significant spatial exclusion in the gallery forest. This might be an indication of no resource use
limitation in this ecosystem, although this hypothesis needs to be tested further. In conclusion
the earthworm community of the gallery forest was not structured by interspecific competition,
although species showed a patchy distribution in space. MenosCompetitive interactions and environmental factors act as filters and both determine community
