Data from: Differences in epiphyte biomass and community composition along landscape and within-crown spatial scales
<p>Vascular epiphytes contribute to the structural, compositional, and functional complexity of tropical montane cloud forests because of their high biomass, diversity, and ability to intercept and retain water and nutrients from atmospheric sources. However, human-caused climate change and forest-to-pasture conversion are rapidly altering tropical montane cloud forests. Epiphyte communities may be particularly vulnerable to these changes because of their dependence on direct atmospheric inputs and host trees for survival. In Monteverde, Costa Rica, we measured vascular epiphyte biomass, community composition, and richness at two spatial scales: (1) along an elevation gradient spanning premontane forests to montane cloud forests; and (2) within trees along branches from inner to outer crown positions. We also compared epiphyte biomass and distribution at these scales between two different land-cover types, comparing trees in closed canopy forest to isolated trees in pastures. An ordination of epiphyte communities at the level of trees grouped forested sites above versus below the cloud base, and separated forest versus pasture trees. Species richness increased with increasing elevation and decreased from inner to outer branch positions. Although richness did not differ between land-cover types, there were significant differences in community composition. The variability in epiphyte community organization between the two spatial scales and between land-cover types underscores the potential complexity of epiphyte responses to climate and land-cover changes.</p>
Data from: Three-dimensional preservation of cellular and subcellular structures reveal 1.6 billion-year-old probable crown-group red algae
The ~1.6 Ga Tirohan Dolomite of the Lower Vindhyan in central India contains phosphatized stromatolitic microbialites. We report from there uniquely well-preserved fossils interpreted as crown-group rhodophytes (red algae). The filamentous form Rafatazmia chitrakootensis n.gen, n.sp. has uniserial rows of large cells and grows through diffusely distributed septation. Each cell has a centrally suspended, conspicuous rhomboidal disk interpreted as a pyrenoid. The septa between the cells have central structures that may represent pit connections and pit plugs. Another filamentous form, Denaricion mendax n.gen., n.sp., has coin-like cells reminiscent of those in large sulfur-oxidizing bacteria, but much more recalcitrant than the liquid-vacuole-filled cells of the latter. Its wider affinities are uncertain. Ramathallus lobatus n.gen., n.sp. is a lobate sessile alga with pseudoparenchymatous thallus and apparent tetraspore formation, suggesting florideophycean affinity. Rafatazmia and Ramathallus are interpreted as crown-group multicellular rhodophytes, antedating the oldest previously accepted red alga in the fossil record by about 400 million years.

Burrow ambient temperature influences Helice crab activity and availability for migratory Red-crowned Cranes Grus japonensis
<p><span><span><span><span><span><span><span><span><span><span><span>For migratory birds that specialize on particular benthic macroinvertebrate species, the timing of migration is critical since prey availability may be temporally limited and a function of local ambient temperature. Hence, variation in local ambient temperature can influence the diet composition of migrant birds, and consequently they may be constrained by which stopover and wintering sites they are able to utilize during periods of colder temperatures. Here we use faecal analysis, observer-based population counts, digital video-recordings, and temperature data to test five predictions regarding the influence of local ambient temperature on the activity and availability of mudflat crabs - a key prey resource at three staging/wintering sites in eastern China, for migratory Red-crowned cranes (<i><span>Grus japonensis</span></i>) and how this subsequently influences crane diet and use of wetland sites. Pearson's correlations and generalised linear models revealed that mudflat crabs became significantly more surface active with increasing burrow ambient temperature. Piecewise regression analysis revealed that crab surface activity was largely limited to a burrow ambient temperature threshold between 12~13℃ after which activity significantly increased. Crab activity declining temporally during the crane's autumn migration period but increased during spring migration. Crabs accounted for a significant proportion of crane diet at two of three sites, however the frequency of crab remains was significantly different between sites, and between autumn and spring migration. Analyses of crane count data revealed a degree of congruence between the migration timing of Red-crowned cranes with periods of warmer ambient temperature, and a significant, positive correlation between the percentage of crab remains in crane faeces and site ambient temperature. Collectively our data suggests that temperature-related mudflat crab activity may provide an important time window for migratory Red-crowned cranes to utilise critical stop-over sites and the crabs' food resources.</span></span></span></span></span></span></span></span></span></span></span></p>
