Data from: Assessing the trophic ecology of top predators across a recolonisation frontier using DNA metabarcoding of diets
Top predator populations, once intensively hunted, are rebounding in size and geographic distribution. The cessation of sealing along coastal Australia and subsequent recovery of Australian Arctocephalus pusillus doriferus and long-nosed A. forsteri fur seals represents a unique opportunity to investigate trophic linkages at a frontier of predator recolonisation. We characterised the diets of both species across 2 locations of recolonisation, one site an established breeding colony, and the other, a new but permanent haul-out site. Using DNA metabarcoding, high taxonomic resolution data on diets was used to inform ecological trait-based analyses across time and location. Australian and long-nosed fur seals consumed 76 and 73 prey taxa, respectively, a prey diversity greater than previously reported. We found unexpected overlap of prey functional traits in the diets of both seal species at the haul-out site, where we observed strong trophic linkages with coastal ecosystems due to the prevalence of benthic, demersal and reef-associated prey. The diets of both seal species at the breeding colony were consistent with foraging patterns observed in the centre of their geographic range regarding diet partitioning between predator species and seasonal trends typically observed. The unexpected differences between sites in this region and the convergence of both predators' effective ecological roles at the range-edge haul-out site correlate with known differences in seal population densities and demographics at these and other newly recolonised locations. This study provides a baseline for the diets and trophic interactions for recovering fur seal populations and from which to understand the evolving ecology of predator recolonisation.
Top-down and bottom-up controls limit woody encroachment into persistent temperate rainforest meadows
<p><span>These data describe soils, woody plant seedlings, and ungulate herbivory in and around temperate montane meadows in the Oregon Coast Range, USA. Meadows such as these are a global study system for the accelerating phenomenon of woody encroachment, but study this phenomenon into meadows in western Oregon has been conducted almost entirely in the western and High Cascades, with only two extant observational studies of grassy balds in the Coast Range. These data describe factors limiting woody encroachment into meadows in the Oregon Coast Range, including bottom-up control by soil properties, plant-plant interactions, and top-down control by large herbivores.<b> </b>I measured chemical and physical properties of soils (depth of organic layer; bulk density of top 3 cm of mineral soil; and mineral soil profiles: particle size distribution, pH, % total C, % total N) to a depth of 50 cm in meadow and forest. I recorded community, density, and proportion browsed for shrubs, conifers, and deciduous trees ≤2 m tall along transects from meadow into forest. I experimentally planted 20 <i>Pseudotsuga menziesii</i> (Douglas-fir) seedlings in each of five meadows (<em>n </em>= 100) and factorially manipulated aboveground neighboring plant presence and ungulate herbivore access. I found that m</span><span>eadow soils were lower in C and C:N; slightly lower in N, and similar in plant-available water (derived from particle size distribution) and pH relative to forest soils. Shrubs were most dense, but experienced the lowest browse pressure, near the meadow edge; while trees were sparse and varied by site—although at one site, browse pressure was heavier in meadow than forest. Seedling survival and growth varied by site, herbivory reduced growth, and total soil N best explained residual variation in seedling growth among sites.</span><span><b> </b>My findings indicate that ungulate herbivores exert top-down control on woody encroachment into temperate montane meadows, perhaps in concert with local N-limitation.</span></p>
Data from: History of expansion and anthropogenic collapse in a top marine predator of the Black Sea estimated from genetic data
Two major ecological transitions marked the history of the Black Sea after the last Ice Age. The first was the postglacial transition from a brackish-water to a marine ecosystem dominated by porpoises and dolphins, once this basin was reconnected back to the Mediterranean Sea (ca. 8,000 years B.P.). The second occurred during the last decades, when overfishing and hunting activities brought these predators close to extinction, deeply impacting the structure and dynamics of the ecosystem. Estimating the extent of this decimation is essential for characterizing this ecosystem's dynamics and for formulating restoration plans. However this extent is poorly documented in historical records. We addressed this issue for one of the main Black Sea predators, the harbor porpoise, using a population genetics approach. Analyzing its genetic diversity using an Approximate Bayesian Computation approach, we show that only a demographic expansion (at most 5,000 years ago) followed by a contemporaneous population collapse can explain the observed genetic data. We demonstrated that both the postglacial settlement of harbor porpoises in the Black Sea and the recent anthropogenic activities have left a clear footprint on their genetic diversity. Specifically, we inferred a strong population reduction (~90%) that occurred within the last five decades, which can therefore clearly be related to the recent massive killing of small cetaceans and to the continuing incidental catches in commercial fisheries. Our study thus provides a first quantitative assessment of these demographically catastrophic events, while also showing that two separate historical events can be inferred from contemporary genetic data.
Data from: Keystone mutualism strengthens top-down effects by recruiting large-bodied ants
Determining the impacts of mutualistic interactions and predator diversity on food webs are two important goals in community ecology. In this study, we examined how predator community variation mediates the strength of top–down effects in the presence and absence of mutualistic interactions. We examined the impacts of predatory ant species that simultaneously prey on leaf-chewing herbivores (Lepidoptera) and engage in food-for-protection mutualisms with sap-feeding herbivores (Hemiptera) in the lower canopy of Connecticut forests. In this 2-year study, we examined three hypothetical mechanisms by which mutualisms can alter the top–down effects of ants: (1) sap feeders increase ant abundance, thus strengthening predatory effects; (2) sap feeders increase the relative abundance of a species that has stronger predatory effects; and (3) changes to predator diversity (species richness) are caused by sap feeders mediating top–down effects of the ant community. Experiments revealed that host plants occupied by sap feeders favored large-bodied ant species in the genus Camponotus, but there were no changes to community-wide ant abundance or ant species richness. Fitting predictions of predation strength based on the functional trait of body size, large-bodied Camponotus suppressed caterpillars and reduced leaf herbivory. This work shows that the ant–hemipteran mutualism, which has been characterized as a keystone interaction, can generate strong top–down effects on leaf-chewing herbivores and herbivory via increasing the relative abundance of species with functional traits relevant to predation, such as body size. Therefore, the emergence of specific ants as keystone predators in a community can be contingent upon their mutualism with sap-feeding Hemiptera.
Data from: Top–down limits on prey populations may be more severe in larger prey species, despite having fewer predators
Variation in the vulnerability of herbivore prey to predation is linked to body size, yet whether this relationship is size‐nested or size‐partitioned remains debated. If size‐partitioned, predators would be focused on prey within their preferred prey size range. If size‐nested, smaller prey species should become increasingly more vulnerable because increasingly more predators are capable of catching them. Yet, whether either of these strategies manifests in top‐down prey population limitation would depend both on the number of potential predator species as well as the total mortality imposed. Here we use a rare ecosystem scale "natural experiment" comparing prey population dynamics between a period of intense predator persecution and hence low predator densities and a period of active predator protection and population recovery. We use three decades of data on herbivore abundance and distribution to test the role of predation as a mechanism of population limitation among prey species that vary widely in body size. Notably, we test this within one of the few remaining systems where a near‐full suite of megaherbivores occur in high density and are thus able to include a thirtyfold range in herbivore body size gradient. We test whether top‐down limitation on prey species of particular body size leads to compositional shifts in the mammalian herbivore community. Our results support both size‐nested and size‐partitioning predation but suggest that the relative top‐down limiting impact on prey populations may be more severe for intermediate sized species, despite having fewer predators than small species. In addition we show that the gradual recovery of predator populations shifted the herbivore community assemblage towards large‐bodied species and has led to a community that is strongly dominated by large herbivore biomass.
Data from: Top carnivore decline has cascading effects on scavengers and carrion persistence
Top carnivores have suffered widespread global declines, with well-documented effects on mesopredators and herbivores. We know less about how carnivores affect ecosystems through scavenging. Tasmania's top carnivore, the Tasmanian devil (Sarcophilus harrisii), has suffered severe disease-induced population declines, providing a natural experiment on the role of scavenging in structuring communities. Using remote cameras and experimentally-placed carcasses, we show that mesopredators consume more carrion in areas where devils have declined. Carcass consumption by the two native mesopredators was best predicted by exploitation competition for carrion, whereas consumption by the invasive mesopredator, the feral cat (Felis catus), was better predicted by the landscape-level abundance of devils, suggesting a relaxed landscape of fear where devils are suppressed. Reduced discovery of carcasses by devils was balanced by increased discovery by mesopredators. Nonetheless, carcasses persisted ~2.6-fold longer where devils have declined, highlighting their importance for rapid carrion removal. The major beneficiary of increased carrion availability was the forest raven (Corvus tasmanicus). Population trends of ravens increased 2.2-fold from 1998-2017, the period of devil decline, but this increase occurred Tasmania-wide, making the cause unclear. This case study provides a little-studied potential mechanism for mesopredator release, with broad relevance to the vast areas of the world that have suffered carnivore declines.
