RNA interference in marine and freshwater sponges [PDF]

, 2011
Background: The marine sponge Tethya wilhelma and the freshwater sponge Ephydatia muelleri are emerging model organisms to study evolution, gene regulation, development, and physiology in non-bilaterian animal systems. Thus far, functional methods (i.e.,

Census of Cnidaria (Medusozoa) and Ctenophora from South American marine waters.

Zootaxa, 2016
We have compiled available records in the literature for medusozoan cnidarians and ctenophores of South America. New records of species are also included. Each entry (i.e., identified species or still as yet not determined species referred to as "sp." in

Effects of Proline and Glycine on the Cnidocyte Discharge of Hydra magnipapillata [PDF]

, 2015
The sense of taste enables animals to utilize environmental cues to detect favorable foods. Through specialized sensory receptors, Cnidarians employ stinging cells called cnidocytes to perform a variety of activities such as locomotion, capturing prey ...

Publish wisely or perish? an open archive for MarBEF [PDF]

, 2005
While scientists are publishing around two million papers annually (Odlyzko, 1998), it is surprising to notice that this growing resource of information is seldom easily accessible, even to those scientists.

Marine benthic flora and fauna of Gourdon Bay and the Dampier Peninsula in the Kimberley region of North-Western Australia [PDF]

, 2011
Surveys undertaken to characterise the marine benthic habitats along the Dampier Peninsula and further south at Gourdon Bay in the Kimberley region of Western Australia were augmented with epibenthic sled sampling of soft and hard bottom habitats.

Morphological and Molecular Identification of Porpita porpita (Hydrozoa: Porpitidae) Larval and Colonial Phases

Diversity
Porpita porpita is a colonial polymorphic hydrozoan distributed in temperate and tropical zones. This species, like most hydrozoans, possesses a metagenetic life cycle with alternating life forms: medusa stage, polypoid colony, and planula larva. However,

Parallel evolution of gravity sensing

Frontiers in Cell and Developmental Biology
Omnipresent gravity affects all living organisms; it was a vital factor in the past and the current bottleneck for future space exploration. However, little is known about the evolution of gravity sensing and the comparative biology of gravity reception.

Primate phylogeny: molecular evidence for a pongid clade excluding humans and a prosimian clade containing tarsiers [PDF]

, 2009
Interpretations of molecular data by the modern evolution theory are often sharply inconsistent with paleontological results. This is to be expected since the theory is only true for microevolution and yet fossil records are mostly about macroevolution.

Recovery at Morvin: SERPENT final report [PDF]

, 2010
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

Whole-proteome tree of life suggests a deep burst of organism diversity. [PDF]

, 2020
An organism tree of life (organism ToL) is a conceptual and metaphorical tree to capture a simplified narrative of the evolutionary course and kinship among the extant organisms.
