1/28 Paper 1: M. Soulé and R. Noss 1998 Rewilding and Biodiversity: Complementary Goals for Continental Conservation. Wild Earth. Soulé and Noss present traditional Biodiversity conservation and #Rewilding as two ideas that are both needed to stop the loss of biodiversity.
Today we're looking at using cattle for restoring and maintaining holarctic landscapes in a paper that concludes a long-term study in northern England

The authors finish up by saying that livestock biodiversity has clear intrinsic value as cultural and social assets well as economic value as a genetic resource. There are many areas in Europe where full rewilding is not accepted but traditional livestock breeds may be.

Today we're looking at tropic effects of large herbivores in a paper that looks at reassembling of herbivore assemblages in Africa

The large mammal community exhibited a high degree of interspecific overlap in the plant taxa utilised. Diet composition differed significantly across feeding guilds, although there was considerable cross-guild overlap

ALT Dietary niche overlap among large-herbivore species and feeding guilds. (a) Bipartite plant–herbivore interaction network. Lines connect the 14 herbivore species (top) to dietary plant mOTUs (bottom, coloured by plant family). Widths of upper boxes reflect the number of samples analysed for each species; widths of lower boxes reflect the relative abundance of each plant mOTU across all samples in the dataset; and widths of connecting lines reflect the relative read abundance of each mOTU within the diet of each species. We show only connections representing ≥1% of each species’ diet (total n = 74). (b) Non-metric dimensional scaling (NMDS) ordination of Bray–Curtis dietary dissimilarity among the a priori feeding guilds listed in Table 1 (stress = 0.16; perMANOVA, pseudo-F3,289 = 12.91, r2 = 0.12, p < 0.001). (c) NMDS ordination of Bray–Curtis dissimilarity among species (same ordination as in panel b, but coloured by species to show community-wide interspecific diet dissimilarity...
The authors also looked at abundance of floodplain plant taxa, where the grass Cynodon dactylon was by far the most abundant.

ALT Availability, utilization, and selectivity of common floodplain plant taxa. (a) Relative availability (proportional areal cover) of the 14 plant taxa representing at least 1% of total plant cover (collectively accounting for >96% of cover). (b) Proportional contribution of each plant mOTU to the diet of each ungulate species; circle size and colour reflect relative read abundance. (c) Jacob’s D selectivity index for each plant taxon, ranging from −1 (strongest avoidance, red) to 1 (strongest selection, blue). Plant taxa sharing the same barcode in the local reference database were combined for the purposes of this analysis
Today we're looking at definition of rewilding in a paper that looks at the implications of having multiple definitions and recommends using restoration instead

and reintroduction science are already well established and underlined by a clear understanding of best practice. A new, poorly defined, term such as rewilding may be counter productive to achieving successful conservation action.
