Species Richness And Abundance

To evaluate the potential of bog ecosystems to recover following peat mining, we compared bird species richness,abundance, and assemblages and vegetation among naturally revegetated and undisturbed bog sites in southeastern Quebec.Based on mining history, we selected 28 sites (12 natural, 9 abandoned after blockcut extraction, and 7 abandoned after vacuumextraction) in 15 bogs. We estimated percent cover for six vegetation strata in 106 plots with 100 m radius, on which bird pointcounts were conducted in 1993 and 1996. Vegetation structure differed significantly between natural, post-blockcut andpost-vacuum sites. While vegetation cover was almost complete in natural sites, abandoned sites, especially post vacuum, wereless vegetated, even after 20 years. Bird species richness and abundance were similar in natural and post-blockcut sites andboth were higher than in post-vacuum sites. Ten of the 28 species studied in detail responded to site perturbation. Among them,the Palm Warbler was most closely associated with natural sites. Bird communities were closely associated with vegetationstructure. Communities of post-blockcut sites were more similar to those of natural bogs than were bird communities ofpost-vacuum sites. Since the blockcut method of peat mining is no longer economically feasible, we conclude that bog habitatrestoration should be accompanied by a preservation “safety net” area to counteract the lasting effect of vacuum peat mining onbird species assemblages.

Large expanses of tropical rainforest have been converted into agricultural landscapes cultivated by smallholder farmers. This is also the case in north-eastern Madagascar; a region that retains a significant proportions of forest cover despite shifting hill rice cultivation and vanilla agroforestry. The region is also a global hotspot for herpetofauna diversity, but how this diversity is affected by land-use change remains largely unknown. Using a space-for-time study design to uncover land-use effects, we compared species diversity and community composition in seven prevalent land uses: unburned (old-growth forest, forest fragment, and forest-derived vanilla agroforest) and burned (fallow-derived vanilla agroforest, woody fallow, herbaceous fallow) land-use types, and rice paddy. We conducted six comprehensives, time-standardized searches across at least ten replicates of each land-use type and applied genetic barcoding to confirm species identification. We documented an outstanding diversity of endemic herpetofauna (119 species): amphibian species richness at the plot level was highest in old-growth forest and significantly lower in all other land-use types. Plot-level reptile species richness was significantly higher in the unburned land-use types than burned land-use types. For both amphibians and reptiles, the less-disturbed land-use types showed more uneven communities and particularly in old-growth forest, the species composition differed significantly from all other land-use types. Amphibians showed a higher level of forest dependency compared to reptiles (38% versus 28% of species exclusively occurred in old-growth forest). Our analyses thus revealed that the two groups respond differently to land-use change: we found less pronounced losses of reptile species richness especially in unburned agricultural habitats, suggesting that reptiles are less susceptible to land-use change than amphibians. Overall, old-growth forest harboured a unique diversity, but some species also thrived in agroforestry systems, especially if these were forest-derived. This highlights the importance of conserving old-growth forests and non-burned land-use types within the agricultural landscape.
