Experimental manipulation of predatory crab species identity (Panopeus obesus vs. Eurytium limosum) and size-structure and assessment of effects on invertebrate densities, sediment properties and plant biomass.
Predatory mud crabs (Panopeus obesus and Eurytium limosum) are two of the main resident infaunal predators in southeastern US salt marshes. Little is known, however, about their effects on important prey species, or their influences on sediment or plant properties. These influences are likely to be dependent on the identity of species and the size-stucture of the population. We therefore manipulated the species identity (Panopeus or Eurtium) and size-structure. The size-structure treatrment had four levels: small [9 individuals, each 18-22mm carapace diameter], medium [6 ind. 24 -28mm], large [3 ind. 32-36mm], mixed (3 small, 2 medium, 1 large, all within same cage). The numbers of crabs in each size-structure treatment were chosen to capture natural size-abundance relationships. The treatments were maintained in experimental cages (70 x 70 x 100 cm, length, width, height) in the mid-Spartina zone at Dean Creek, Sapelo Island, GA. We maintained the treatments over 4 months (July - October 2010), before assessing impacts on prey densitities (mud fiddler crabs, ribbed mussels and marsh periwinkles), and ecosystem properties (aboveground plant biomass, sediment redox potential, sediment water content).
Data from: Accounting for predator species identity reveals variable relationships between nest predation rate and habitat in a temperate forest songbird
<p><strong>Abstract</strong></p> <p>Nest predation is the primary cause of nest failure in most ground-nesting bird species. Investigations of relationships between nest predation rate and habitat usually pool different predator species. However, such relationships likely depend on the specific predator involved, partly because habitat requirements vary among predator species. Pooling may therefore impair our ability to identify conservation-relevant relationships between nest predation rate and habitat. We investigated predator-specific nest predation rates in the forest-dependent, ground-nesting wood warbler <em>Phylloscopus sibilatrix </em>in relation to forest area and forest edge complexity at two spatial scales, and to the composition of the adjacent habitat matrix. We used camera traps at 559 nests to identify nest predators in five study regions across Europe. When analysing predation data pooled across predator species, nest predation rate was positively related to forest area at the local scale (1,000 m around nest), and higher where proportion of grassland in the adjacent habitat matrix was high but arable land low. Analyses by each predator species revealed variable relationships between nest predation rates and habitat. At the local scale, nest predation by most predators was higher where forest area was large. At the landscape scale (10,000 m around nest), nest predation by buzzards <em>Buteo buteo</em> was high where forest area was small. Predation by pine martens Martes martes was high where edge complexity at the landscape scale was high. Predation by badgers <em>Meles meles </em>was high where the matrix had much grassland but little arable land. Our results suggest that relationships between nest predation rates and habitat can depend on the predator species involved and may differ from analyses disregarding predator identity. Predator-specific nest predation rates, and their relationships to habitat at different spatial scales, should be considered when assessing the impact of habitat change on avian nesting success.</p>
Tree species identity, diameter and qualitative canopy health measurements (full, partial or dead) from 2005 to 2023 on 12 experimental oak loss plots in Black Rock Forest, NY.
Black Rock Forest established a series of 12, 0.56 ha plots in 2005 to assess impacts of the loss of tree in the genus Quercus on the forest ecosystem (entitled the Future of Oak Forests experiment). Three trunk girdling treatments, with control plots were instituted in 2008. Each plot also contained an ~10m by ~15m deer exclosure to assess the impact of herbivory post-disturbance. Trees were measured twice per year from 2008 to 2013 (except 2009 when trees were measured once) and once per year from 2014 to 2023. Data include tree species identity, diameter at breast height (DBH), canopy health (a qualitative assessment of approximate cover as full, partial or dead), presence/absence of sprouts, and location within the plot. All live trees equal to or larger than 2.5 cm DBH are included in the dataset.

Fig. 4. Shell diversity across the molecular phylogeny of the "deep-water" clade of the subfamily Turbininae (Williams 2007, i.e., the genera Astraea, Bellastraea , Bolma and Guildfordia). The phylogeny is based on Bayesian analyses of the concatenated sequences from cox1 and 28 S genes, incorporating an uncorrelated relaxed, log- normal clock produced using *BEAST. The tree is a maximum clade credibility tree with median node heights based in 9000 trees. Support values are posterior probabilities (PP); branches < 50% were collapsed. Species names are labelled on the right-hand side. Species hypotheses previously delineated by the integrative taxonomy approach are highlighted by the grey boxes.

Fig. 2. [next page] Molecular based species delineation of the genus "Bolma". A. Ultrametric tree produced using BEAST based on cox1 sequences. B. PSHs derived from the GMYC model and labelled from 1 to 37. C. PSHs derived from the GMYC model using the lower limit of the equivalent of a 95% confidence interval, and labelled from A to ZD. D. SSHs drawn from congruency between cox1 and 28S. Boxes with a black outline indicate that the SSH was monophyletic in both cox1 and 28S trees. Boxes without a black outline highlight SSHs for which molecular data were either incomplete or non-informative. SSHs labelled from A to ZD (following step C) or with the species name when our sequences matched published data associated with the species names. E. PSHs derived from the Bayesian analysis based on 28S sequences. F. Bayesian, non-ultrametric tree produced using BEAST based on 28S sequences. G. Species names retained in the present study. For the SSH E-F-G-H, the name Bo. henica was retained; however, Bo. henica abyssorum, Bo. henica madagascarensis and Bo. henica henica are represented as sub-species separated by white dotted lines. For both trees, nodal support values are posterior probabilities (PP), shown only for PP> 50%. Branches with PP <50% were collapsed. Red and green branches correspond to monophyletic species hypotheses. Colour coded boxes: red corresponds to cox1 PSHs supported by PP> 95%; light red corresponds to cox1 PSH supported by PP <95%; light grey corresponds to cox1 and 28S singletons; a grey cross represents missing data; green corresponds to 28S species hypotheses supported by PP> 95%; light grey corresponds to groups of genotypes displaying diagnostic 28S sites. Specimen numbers are given in the Supplementary file.
