Data from: Direct and indirect effects of pine silviculture on the larval occupancy and breeding of declining amphibian species
1. Plantation silviculture is increasing globally and is particularly intensive in temperate coniferous forests, where densely planting trees requires practices common to non-conifer systems that can alter forest floor microhabitat, and potentially threaten amphibian persistence. Most declining amphibian species depend on specific forest microhabitats as terrestrial refugia, but amphibian extirpation associated with tree harvest alone appears unlikely, suggesting that impacts of planting forests on groundcover might better predict recent declines in amphibian occupancy. 2. We repeatedly sampled larval presence or absence of 10 amphibian species native to temperate coniferous forest in the Southeastern United States for one year at 62 isolated wetlands located in either naturally regenerating or planted forest (plantation) to assess three direct ways that planted forests might reduce amphibian breeding site occupancy by: 1) increasing conifer densities, 2) decreasing groundcover, and 3) an indirect pathway, whereby increased tree densities at plantations might reduce groundcover and thus amphibian site occupancy. 3. After controlling for wetland traits and accounting for differences in detection, breeding site occupancy for 8/10 amphibian species was dependent upon whether forests were planted surrounding wetlands (within 300 m). Herbaceous groundcover, not canopy, most commonly influenced occupancy and increased occupancy for declining surface active or fossorial amphibians. 4. Path analyses showed that, by directly and indirectly reducing groundcover (via conifer densities), plantations had significantly lower occupancy of two declining surface active or fossorial frog species, whereas two common aquatic frog species were tolerant to planting conifers. Among declining species, salamanders showed a greater reduction in occupancy than anurans, likely because of greater vulnerability to the drier forest floor conditions of plantation than naturally regenerating forests. 5. Synthesis and applications: Direct negative impacts of coniferous plantation on amphibians can be addressed by limiting groundcover and soil impacts, including switching from high intensity practices, such as mechanical chopping vegetation or bedding soil, to lower intensity site preparation treatments that are less likely to significantly disturb groundcover. Indirect negative effects of dense canopy cover at planted forests could be lowered by periodically thinning canopies prior to final harvest, thus increasing intact forest groundcover and the conservation of both common and declining amphibians.
The role of phylogenetic scale in Darwin's naturalization conundrum in the critically imperiled pine rockland ecosystem
<p><span><span><span><span><span><span><span><span><span><span><span><u><span><span>Aim</span></span></u><span><span>: We expand on community phylogenetic approaches to Darwin's Naturalization Conundrum by considering phylogenetic scale, comprised of phylogenetic grain and extent. We assess relatedness between <i>invasive</i>, <i>non-native</i>, and <i>native</i> plant species at multiple depths in the phylogeny (i.e., phylogenetic grain) and across multiple clades (i.e., phylogenetic extents) at regional and local spatial scales in the highly-fragmented, critically imperiled pine rockland ecosystem. </span></span></span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><u><span><span>Location</span></span></u><span><span>: Miami-Dade County, Florida, USA</span></span></span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><u><span><span>Methods</span></span></u><span><span>: We used two metrics differing in phylogenetic grain to determine if <i>i</i><i>nvasive</i> or <i>non-native</i> species were more closely related to <i>native</i> species in the regional pool and at 33 habitat fragments. At both spatial scales, we altered phylogenetic extent from all vascular plants to four smaller phylogenetic domains (Monilophyte, Gymnosperm, Monocotyledon, and Dicotyledon) and assessed whether the interpretation of relatedness changed. </span></span></span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><u><span><span>Results</span></span></u><span><span>: For the regional pool and at a broader phylogenetic grain, <i>non-native</i> species were more closely related to the <i>native </i>community than <i>invasive</i> species were for all phylogenetic extents (i.e., support for Darwin's Naturalization Hypothesis, DNH), and at a finer phylogenetic grain for only two phylogenetic extents. At the local scale, there was limited support for DNH across all phylogenetic extents. In Monocotyledons, support for DNH was more prevalent at the fine phylogenetic grain while Dicotyledons showed support for DNH at the broad phylogenetic grain.</span></span></span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><u><span><span>Main conclusions</span></span></u><span><span>: In the pine rockland flora, we found either support for DNH or no difference in relatedness between <i>non-native</i>-to-<i>native</i> and <i>invasive-</i>to-<i>native</i> species. However, patterns of relatedness varied across spatial and phylogenetic</span></span> grain and, critically, this variability is highly dependent on the phylogenetic extent considered. By explicitly assessing the interactions between spatial scale and phylogenetic scale, we show that support for DNH was context dependent, and findings at smaller phylogenetic extents rarely agreed with findings at the larger phylogenic extent. </span></span></span></span></span></span></span></span></span></span></span></p>
Lignin concentrations in phloem and outer bark are not associated with resistance to mountain pine beetle in high elevation pines
<p>A key component to understanding plant-insect interactions is the nature of host defenses. Research on defense traits among <i>Pinus</i> species has focused on specialized metabolites and axial resin ducts, but the role of lignin in defense within diverse systems is unclear. We investigated lignin levels in the outer bark and phloem of <i>P. longaeva</i>, <i>P. balfouriana</i>,<i> </i>and<i> P. flexilis</i>; high elevation species in the western United States known to differ in susceptibility to mountain pine beetle (<i>Dendroctonus ponderosae</i>; MPB). Relative to <i>P. flexilis</i>, <i>P. longaeva</i> and <i>P. balfouriana</i> are attacked by MPB less frequently, and MPB brood production in <i>P. longaeva</i> is limited. Because greater lignification of feeding tissues has been shown to provide defense against bark beetles in related genera, such as <i>Picea</i>, we hypothesized that <i>P. longaeva</i> and <i>P. balfouriana</i> would have greater lignin concentrations than <i>P. flexilis</i>. Contrary to expectations, we found that the more MPB-susceptible <i>P. flexilis</i> had greater phloem lignin levels than the less susceptible <i>P. longaeva</i> and <i>P. balfouriana</i>. No differences in outer bark lignin levels among the species were found. We conclude that lignification in <i>Pinus</i> phloem and outer bark is likely not adaptive as a physical defense against MPB.</p>
