Data files from MALD1 - Massive Auditory Lexical Decision

Data files used for analyses in manuscript titled "Soil development limits alpine plant establishment in recently-deglaciated terrain". The original data was collected in 2016/2017 and analyzed to be included in MSc. thesis titled "Characteristics of alpine plants and soils along an elevational gradient, Northern Selkirk Mountains, British Columbia". These files contain data used in analyses of plant community composition and soil properties along an environmental gradient, age structure of the treeline ecotone, PLFA's, and transplant survival.

This is a dataset associated with the article, "Zhuangzi and Laozi: an Intertextual Approach", and published in the Dao Companion to Zhuangzi.

Sponges (Porifera) are among the earliest evolving metazoans. Their filter-feeding body plan based on choanocyte chambers organized into a complex aquiferous system is so unique among metazoans that it either reflects an early divergence from other animals prior to the evolution of features such as muscles and nerves, or that sponges lost these characters. Analyses of the Amphimedon and Oscarella genomes support this view of uniqueness—many key metazoan genes are absent in these sponges—but whether this is generally true of other sponges remains unknown.We studied the transcriptomes of eight sponge species in four classes (Hexactinellida, Demospongiae, Homoscleromorpha, and Calcarea) specifically seeking genes and pathways considered to be involved in animal complexity. For reference, we also sought these genes in transcriptomes and genomes of three unicellular opisthokonts, two sponges (A. queenslandica and O. carmela), and two bilaterian taxa. Our analyses showed that all sponge classes share an unexpectedly large complement of genes with other metazoans. Interestingly, hexactinellid, calcareous, and homoscleromorph sponges share more genes with bilaterians than with nonbilaterian metazoans. We were surprised to find representatives ofmostmolecules involved in cell–cell communication, signaling, complex epithelia, immune recognition, and germ-lineage/sex, with only a few, but potentially key, absences. A noteworthy finding was that some important genes were absent from all demosponges (transcriptomes and the Amphimedon genome), which might reflect divergence from main-stem lineages including hexactinellids, calcareous sponges, and homoscleromorphs. Our results suggest that genetic complexity arose early in evolution as shown by the presence of these genes in most of the animal lineages, which suggests sponges either possess cryptic physiological and morphological complexity and/or have lost ancestral cell types or physiological processes.
