BACKGROUND Annelida comprises an ancient and ecologically important animal phylum with over 16,500 described species and members are the dominant macrofauna of the deep sea. Traditionally, two major groups are distinguished: Clitellata (including earthworms, leeches) and "Polychaeta" (mostly marine worms). Recent analyses of molecular data suggest that(More)
—This article describes an approach for providing dy­ namic quality of service (QoS) support in a variable bandwidth net­ work, which may include wireless links and mobile nodes. The dy­ namic QoS approach centers on the notion of providing QoS support at some point within a range requested by applications. To utilize dynamic QoS, applications must be(More)
Next-generation sequencing technology is now frequently being used to develop genomic tools for non-model organisms, which are generally important for advancing studies of evolutionary ecology. One such species, the marine annelid Streblospio benedicti, is an ideal system to study the evolutionary consequences of larval life history mode because the species(More)
This paper presents an approach to supporting Quality of Service (QoS) in a dynamic network environment. With this approach, resource reservations represent ranges, and applications adapt to an allocated level of QoS provided by the network at some point within the requested range. To explore this approach, we have implemented a new protocol called dynamic(More)
The echinoderm symbionts Myzostomida are marine worms that show an enigmatic lophotrochozoan body plan. Historically, their phylogenetic origins were obscured due to disagreement about which morphological features are evolutionarily conserved, but now most morphological evidence points to annelid origins. In contrast, recent phylogenetic analyses using(More)
This paper looks at issues involved in attempting to provide Quality of Service (QoS) support in a dynamic environment. We focus on a resource reservation based approach, which we believe is attractive for military applications, but becomes especially difficult in a dynamic network environment. This is because available resources reserved for a particular(More)
This paper evaluates the performance of several alternative reliable unicast transport mechanisms in a hybrid network. Options investigated include end-to-end TCP (different flavors), end-to-end Space Communications Protocol Standards-Transport Protocol (SCPS-TP), and Performance Enhancing Proxies (PEPs) (also called Transport Layer Proxies). Our approach(More)
This paper describes a recent simulation-based evaluation of several unicast routing protocols tailored specifically for mobile ad hoc networks 1. Four protocols were evaluated: the Wireless Internet Routing Protocol (WIRP), a Link State (LS) algorithm with constrained LS updates, a Distance Vector variant of WIRP, and Temporally Ordered Routing Algorithm(More)
