TLDR
A new genus and species of Hydromedusae is described from the waters off North Queensland, which represents the first record of the Dipleurosomatidae in Australian waters.Abstract:
A new genus and species of Hydromedusae is described from the waters off North Queensland. It is placed in the Dipleurosomatidae because of its irregularly branched radial canals, gonads on the radial canals separated from the stomach, hollow marginal tentacles and lack of cirri or cordyli. It differs from all other medusae in its two rows of small, simple, wart-like gonadal papillae. It differs from the other dipleurosomatids in its unique combination of other characters, namely, 5-6 radial canals leaving the stomach, branching dichotomously an irregular number of times; about half as many tentacles as canal branches reaching ring canal, not in correspondence with canal branches; with about 8 globular or heart-shaped stalked clubs between successive tentacles; and lacking ocelli. This report represents the first record of the Dipleurosomatidae in Australian waters. Cnidaria, Hydrozoa, Leptomedusae, Dipleurosomatidae, Hydromedusae.read more

TL;DR: All the nesting populations in the Mediterranean should be considered as management units sharing immature pelagic habitats throughout the Mediterranean (and possibly the eastern Atlantic), with distinct and more localized benthic feeding habitats in the eastern basin used by large immatures and adults.

The Diversity and Biogeography of Western Indian Ocean Reef-Building Corals
TL;DR: Diversity patterns were consistent with primary oceanographic drivers in the WIO, reflecting inflow of the South Equatorial Current, maintenance of high diversity in the northern Mozambique Channel, and export from this central region to the north and south, and to the Seychelles and Mascarene islands.

TL;DR: By reviewing sponge development in an evolutionary and phylogenetic context, this work supports previous suggestions that sponge larvae share traits and complexity with eumetazoans and that the simple sedentary adult lifestyle of sponges probably reflects some degree of secondary simplification.

TL;DR: A large (861 species) global dataset of lizard body temperatures was used, and the mean annual temperatures across their geographic ranges were examined to examine the relationships between body andmean annual temperatures.

A Basal Alvarezsauroid Theropod from the Early Late Jurassic of Xinjiang, China
TL;DR: A more complete early specimen is described, dating to about 160 million years ago, which supports the conclusion that Alvarezsauroidea are a basal group of the clade containing both birds and their close theropod relatives and confirms that this group is a basal member of Maniraptora.

TL;DR: During 1943, 110 titles concerning population densities and home ranges of about 60 species of North American small mammals, covering most of the titles on the subject through 1941, were summarized by the writer, intended to compare methods and results of censuses.

Outgroup analysis and parsimony
TL;DR: Methods that use outgroups in the reconstruction of phylogeny are described and evaluated by the criterion of parsimony, and algorithms and rules are presented that find the most parsimonious estimates of ancestral states for binary and multistate characters when outgroup relationships are well resolved.

TL;DR: Proposed categories of threat based on the theory of extinction times for single populations and on meaningful time scales for conservation action are presented and suggest are appropriate at least for most large vertebrates.
