The Murray Darling Basin Plan is not delivering - there\u27s no more time to waste
More than five years after the Murray Darling Basin Plan was implemented, it\u27s clear that it is not delivering on its key objectives. The Basin Plan, at its core, is about reducing the amount of water that can be extracted from its streams, rivers and aquifers. It includes an environmental water strategy to improve the conditions of the wetlands and rivers of the basin. The Productivity Commission will conduct a five-yearly inquiry into the effectiveness of the Basin Plan in 2018. It is high time to explain what is really going on in the Basin and water recovery. For this reason we have all signed the Murray-Darling Basin Declaration to explain what has gone wrong, to call for a freeze on funding for new irrigation projects until the outcomes of water recovery has been fully and independently audited, and to call for the establishment of an independent, expert body to deliver on the key goals of the Water Act (2007)
Measuring Biodiversity and Extinction – Present and Past
How biodiversity is changing in our time represents a major concern for all organismal biologists. Anthropogenic changes to our planet are decreasing species diversity through the negative effects of pollution, habitat destruction, direct extirpation of species, and climate change. But major biotic changes – including those that have both increased and decreased species diversity – have happened before in Earth’s history. Biodiversity dynamics in past eras provide important context to understand ecological responses to current environmental change. The work of assessing biodiversity is woven into ecology, environmental science, conservation, paleontology, phylogenetics, evolutionary and developmental biology, and many other disciplines; yet, the absolute foundation of how we measure species diversity depends on taxonomy and systematics. The aspiration of this symposium, and complementary contributed talks, was to promote better understanding of our common goals and encourage future interdisciplinary discussion of biodiversity dynamics. The contributions in this collection of papers bring together a diverse group of speakers to confront several important themes. How can biologists best respond to the urgent need to identify and conserve diversity? How can we better communicate the nature of species across scientific disciplines? Where are the major gaps in knowledge about the diversity of living animal and plant groups, and what are the implications for understanding potential diversity loss? How can we effectively use the fossil record of past diversity and extinction to understand current biodiversity loss
Diez retos para transformar la TaxonomÃa
10 pages.[EN] Taxonomy is at a crossroads. Although taxonomy has an impressive past, having
documented and organized knowledge of nearly two million species, most of the basic
work required to describe Earth’s biodiversity remains undone. Factors that guide the
choices of research topics in science are considered. Ten challenges are presented to the
taxonomic community that we believe will accelerate its revitalization.[ES] La TaxonomÃa se encuentra en una encrucijada. Con un admirable pasado que ha permitido
documentar y organizar un inmenso conocimiento sobre casi dos millones de
especies, sin embargo, la tarea básica de describir la Biodiversidad sobre la Tierra está
por hacer. Se examinan los factores que guÃan la elección de lÃneas de investigación en
la ciencia y se propone a la comunidad taxonómica, diez retos que consideramos acelerarán
su revitalización.A. G. V. was supported with a grant of the SecretarÃa de

Revolutionary thoughts on taxonomy: declarations of independence and interdependence
Credible biological research depends on accurate species identifications, reliable scientific names, and an evolutionary context provided by a phylogeny or phylogenetic classification. The emphasis on such taxonomic services has detracted from the fundamental taxonomic research necessary to create and sustain such knowledge systems. A taxonomic declaration of independence is presented, emphasizing the unique mission, goals, and needs of taxonomists and taxonomic (collection-based) institutions and the non-experimental yet scientifically rigorous epistemology of taxonomy. At the same time taxonomic interdependence is declared. Questions pursued by taxonomists are planetary in scale and can only be answered given international collaboration and coordination in the growth and development of natural history collections and taxonomic hypotheses. Reciprocity of open access is urged between all nations and the taxonomic community creating information. Countries home to species diversity should allow access to taxon experts so that the world's species are discovered and described. In exchange all specimens collected should be in publicly accessible museums and all resultant taxonomic data, information, and knowledge should be openly available to all who can use them
