Vital Action

In this paper its author describes the results of experiments made with two intents—one, to endeavour to ascertain whether there can be a complete arrest of vital action without the death of the egg; the other to ascertain the changes which take place in those instances in which, during incubation, the egg proves unproductive.The eggs used were chiefly those of the common fowl. The trials to which they were subjected were of three kinds—the airpump, the ice-house, and immersion in lime-water.

Vital Action

Jean-Jacques Rousseau expressed the need to be genuinely understood. This need is manifest in the precision with which he describes in his Confessions the kinesthetic valence of his emotional experiences and the impact kinesic dialogues had on him. Several of the kinesic dialogues he records in his autobiography revolve around surprising shifts in tonicity, tone, and tempo in verbal utterances, gestures, and the vital action of breathing. This chapter considers four such passages, including a scene of writing in which Rousseau’s emotional state is specifically communicated by the very fact that his handwriting is unreadable owing to the trembling of his hand.

<em>Abstract</em>.—Traditional approaches to fish conservation have focused on the protection of small habitat patches or on individual species at risk of extinction. These strategies have been important yet largely have been too little and too late for widespread protection of aquatic faunas. Such small-scale and reactive approaches also are costly in terms of recovery programs and aggressive in terms of regulatory controls. Further, the linear nature of streams and the networked configuration of drainage systems suggest that a fundamentally different approach to reserve design and protected areas is necessary for effective conservation of freshwater communities when compared to terrestrial systems. Larger-scale, multispecies approaches to native fish conservation offer a more efficient and effective conservation strategy because entire fish communities and the ecological processes that support maintenance of habitat diversity can be sustained before the status of individual species deteriorates to critical levels. Protecting entire communities and watersheds also offers some resistance to climate change impacts, which rapidly are altering flow regimes and disturbance dynamics in aquatic systems. Identification and protection of high-value aquatic communities will provide an important supplement to current conservation strategies during times of increasing threats and future uncertainty.

<em>Abstract</em>.—Texas harbors 191 species of native freshwater fishes, 48% of which are considered imperiled. The primary cause of fish species imperilment in Texas is anthropogenic alteration of freshwater systems, which continues to occur at rates and scales that threaten the long-term resiliency of freshwater habitats, species, and ecosystems. Innovative conservation approaches are needed to restore and maintain functional watershed processes, restore freshwater habitats, and conserve native species while simultaneously supporting human needs, such as flood control, municipal and agricultural water supply, water quality protection, and water-based recreation. The need for an integrated and holistic approach to conservation of freshwater systems has been the impetus for development of the Texas Native Fish Conservation Areas Network (hereafter “Texas NFCAs Network”). The Texas NFCAs Network consists of springs, ciénegas, creeks, rivers, and associated watersheds uniquely valued in preservation of Texas freshwater fish diversity. Twenty native fish conservation areas have been designated throughout the state. These were selected based on a spatial prioritization focused on identification of freshwater systems critically important to the long-term persistence of 91 freshwater fishes considered species of greatest conservation need. Through a shared vision of collaborative stewardship, conservation partnerships have formed among nongovernmental organizations, universities, and state and federal agencies to plan and deliver actions within the Texas NFCAs Network to restore and preserve native fishes and their habitats. Furthermore, the Texas NFCAs Network has increased awareness of the ecological, recreational, and economic values of Texas freshwater systems and helped increase interest and capacity of local landowners, communities, and recreational users (e.g., paddlers, anglers) to act as advocates and local stewards of these systems. By facilitating partnership development, coordinating broad-based conservation planning, and leveraging technical and financial resources toward strategic conservation investments, the Texas NFCAs Network has served as a catalyst for collaborative, science-based stewardship of native freshwater fishes and their habitats in Texas. The Texas NFCAs Network offers a successful case study in multispecies and watershed approaches to freshwater fish conservation transferrable to other states in the United States, with particular relevance to those states that, similar to Texas, consist predominately of privately owned landscapes.
