Leverage points for addressing marine and coastal pollution: A review.

Despite an increasing understanding of the issue of marine pollution, humanity continues on a largely unsustainable trajectory. This study aimed to identify and classify the range of scientific studies and interventions to address coastal and marine pollution. We reviewed 2417 scientific papers published between 2000 and 2018, 741 of which we analysed in depth.

[The jibarization of logos: how medical reductionism can kill].

In recent decades, a disciplinary and subdisciplinary proliferation has triggered both in the medical fields and science in general. This trend may be partially explained by two diachronic, dialectically interconnected facts: the deepening of technical, social and international division of labor in the globalized capitalist world, and the triumph of the reductionist program, mainly developed by the logical empiricism of the Vienna Circle. This paper aims to deepen the debate on the intricate links between medicine, biology, philosophy, reductionism and complex thought, by using two examples: a case report of current medicine and the situation experienced by a famous American scientist, Stephen Jay Gould, about his first cancer, an abdominal mesothelioma.

Long necks enhance and constrain foraging capacity in aquatic vertebrates.

Highly specialized diving birds display substantial dichotomy in neck length with, for example, cormorants and anhingas having extreme necks, while penguins and auks have minimized necks. We attached acceleration loggers to Imperial cormorants and Magellanic penguins , both foraging in waters over the Patagonian Shelf, to examine the difference in movement between their respective heads and bodies in an attempt to explain this dichotomy. The penguins had head and body attitudes and movements that broadly concurred throughout all phases of their dives.

A spherical-plot solution to linking acceleration metrics with animal performance, state, behaviour and lifestyle.

Background: We are increasingly using recording devices with multiple sensors operating at high frequencies to produce large volumes of data which are problematic to interpret. A particularly challenging example comes from studies on animals and humans where researchers use animal-attached accelerometers on moving subjects to attempt to quantify behaviour, energy expenditure and condition.

Results: The approach taken effectively concatinated three complex lines of acceleration into one visualization that highlighted patterns that were otherwise not obvious.

Post-mortem findings in southern right whales Eubalaena australis at Península Valdés, Argentina, 2003-2012.

Between 2003 and 2012, 605 southern right whales (SRW; Eubalaena australis) were found dead along the shores of Península Valdés (PV), Argentina. These deaths included alarmingly high annual losses between 2007 and 2012, a peak number of deaths (116) in 2012, and a significant number of deaths across years in calves-of-the-year (544 of 605 [89.9%]; average = 60.
