Neonatal modification of the microbial inoculum entering the gastrointestinal tract mayalter the rumen microbiome and consequently alter pre- and post-weaning rumen fer-mentation and growth of lambs. This study aimed to determine (1) if modifying the rumenby providing ewes with lipids differing in rumen-availability in late gestation and lacta-tion would affect performance of the lamb offspring and (2) whether cross-inoculation ofneonatal lambs with digesta from sheep on an alternate diet would modify the fermen-tation, size, and characteristics of the developing rumen and performance of lambs. Twodiets were offered ad libitum to 36 pregnant ewes (and to their lambs after lambing) from1 month pre-lambing until 2 weeks after weaning, after which lambs were grazed in treat-ment groups in paddocks. Diets consisted of 92% of a blend of oaten and lucerne choppedhay, 4% molasses and 4% fat (coconut oil ? CO or protected fat ? PF). Newborn lambs wereinoculated weekly while suckling (weeks one to eight postnatal) with fresh rumen fluidfrom donor ewes eating CO or PF diets, or were inoculated with water. Lamb body weight,condition score, wool growth, rumen fermentation, and rumen development were stud-ied during the first 5 months of life of the lambs. Diet and inoculation affected dry matterintake after weaning (P < 0.05), being lower in lambs eating CO or inoculated with water.Feeding of CO instead of PF reduced the protozoa population and daily methane produc-tion of lambs (P < 0.05). Type of gut inoculum had an effect on the concentrations of acetate,propionate, butyrate, total volatile fatty acids, and total protozoa numbers in the rumen oflambs during lactation. By weaning, effects of post-natal inoculation were only apparent forthe concentration of butyrate and the protozoal population. It is concluded that dietary fatcan affect rumen development and fermentation of the lambs. In addition inoculation withexogenous rumen fluid can modulate some aspects of rumen fermentation. However, lambperformance evaluated at weaning and at 5 months after birth was not altered by eitherdiet or early-life inoculum, suggesting that while the rumen microbiome may have plas-ticity in its composition, microbial changes do not necessarily result in improved animalperformance.

ABSTRACT.- The spatial mapping of social-ecological system (SES) archetypes constitutes a fundamental tool to operationalize the SES concept in empirical research. Approaches to detect, map, and characterize SES archetypes have evolved over the last decade towards more integrative and comparable perspectives guided by SES conceptual frameworks and reference lists of variables. However, hardly any studies have investigated how to empirically identify the most relevant set of indicators to map the diversity of SESs. In this study, we propose a data-driven methodological routine based on multivariate statistical analysis to identify the most relevant indicators for mapping and characterizing SES archetypes in a particular region. Taking Andalusia (Spain) as a case study, we applied this methodological routine to 86 indicators representing multiple variables and dimensions of the SES. Additionally, we assessed how the empirical relevance of these indicators contributes to previous expert and empirical knowledge on key variables for characterizing SESs. We identified 29 key indicators that allowed us to map 15 SES archetypes encompassing natural, mosaic, agricultural, and urban systems, which uncovered contrasting land sharing and land sparing patterns throughout the territory. We found synergies but also disagreements between empirical and expert knowledge on the relevance of variables: agreement on their widespread relevance (32.7% of the variables, e.g. crop and livestock production, net primary productivity, population density); relevance conditioned by the context or the scale (16.3%, e.g. land protection, educational level); lack of agreement (20.4%, e.g. economic level, land tenure); need of further assessments due to the lack of expert or empirical knowledge (30.6%). Overall, our data-driven approach can contribute to more objective selection of relevant indicators for SES mapping, which may help to produce comparable and generalizable empirical knowledge on key variables for characterizing SESs, as well as to derive more representative descriptions and causal factor configurations in SES archetype analysis.
