| | Monitoring Riparian Arthropod Assemblages |
 | | Assemblages of arthropod taxa may be selected and monitored as indicators of functional groups that both reflect and influence ecosystem processes (Noss, 1990; Chapin et al. | | | The analysis of relative abundances of specific assemblages of taxa that represent ecosystem processes, such as herbivores and prey, at restored and reference sites may provide an objective, scientific basis for choosing among management alternatives. | | | Many of the taxa collected are prey of birds that feed by gleaning prey from foliage. |

| | This allows us to examine how pecan interacts and survives with arthropods in natural situations and then to focus on how and why particular arthropods achieve pest status in commercial situations. | | | This makes excellent economic sense when all applications are really needed but can result in unnecessary costs or even disasters when one or more of the treatments are not needed. | | | This necessitates increased fungicide treatments at shorter intervals using machinery that provides thorough coverage of the foliage. |

| | Arthropod - Wikipedia, the free encyclopedia |
| | Most arthropods respire (breathe) through a tracheal system (exceptions are Pauropoda, some thysanurans and some arachnids like many mites); a potential difficulty considering that the skeletal structure is external and covers nearly all of the body. | | | Wikibooks Dichotomous Key has more about this subject: | | | This is in fact what gives arthropods their name — jointed feet — and separates them from their relatives, the Onychophora and Tardigrada, also called Lobopoda (and which is sometimes included in a group called Panarthropoda, that also includes true arthropods). |

| | Arthropod - MSN Encarta |
| | Many small and primitive arthropods absorb all the oxygen that they need through their exoskeleton. | | | For example, an exoskeleton has to be shed, or molted, if growth is to occur, and during this process, the animal is soft and vulnerable. | | | Arthropods possess an open circulatory system in which the heart forces blood through the body cavity to bathe internal tissues with nutrients from the digestive system. |

| | Palaeos Invertebrates: Arthropoda: Arthropod Phylogeny - problems in interpreting the Arthropod family tree |
| | Many fossil forms are known, but it is always difficult to make assertions regarding what little can be gleaned from the gross morphology preserved. | | | The closer one gets to modern taxa, the more reliable findings may be, but even there is an element of uncertainty (as shown by the rival interpretations regarding myriapod relationships, left), which may remain for some time to come. | | | For example, Sarotrocercus, said at different times to be close to Limulus and a eurypterid, then to Yohoia and Sanctacaris, and most recently to Molaria and Leonchoilia, bears little resemblance to any of these very different animals and is in fact one of the most primitive arthropods yet discovered. |

| | Rickettsial Pathogens and their Arthropod Vectors |
| | In this article, we focus on the members of the typhus group (TG) and spotted fever group (SFG) rickettsiae to construct a conceptual framework of the natural history of human rickettsioses and evaluate feeding behavior of the vectors with regard to rickettsial maintenance and transmission. | | | Recent work in our laboratory with TG rickettsiae suggests that interspecific competition between closely related rickettsiae may control rickettsial establishment in arthropods. | | | Although rickettsiae have a symbiotic relationship with their arthropod hosts, in some instances, they act as true parasites—for example, members of the Wolbachia and Orientia tsutsugamushi alter reproduction and manipulate cellular processes in their arthropod hosts (4), and the agent of epidemic typhus, Rickettsia prowazekii, kills its vector, the human body louse (5). |
