Wounded Amazon
Wounded Amazon, Rome, 150 A.D., Marble, Nye Carlsberg Glyptotek (Copenhagen, Denmark). Made with Memento Beta (now ReMake) from AutoDesk. The amazon has a sword cut under her right arm, from which blood is trickling. It is said that famous Greek artist competed for the honour of executing a statue of a wounded Amazon for the Temple of Artemis at Ephesos.

Common ant species dominate morphospace: unraveling the morphological diversity in the Brazilian Amazon Basin
<p>Rare plant and vertebrate species have been documented to contribute disproportionately to the total morphological structure of species assemblages. These species often possess morphologically extreme traits and occupy the boundaries of morphological space. As rare species are at greater risk of extinction than more widely distributed species, human-induced disturbances can strongly affect ecosystem functions related to assemblage morphology. Here, we assess to what extent the distributions of ant morphological traits are supported by morphologically extreme species and how they are distributed among habitats in a global biodiversity hotspot, the Brazilian Amazon. We used a morphological database comprising 15 continuous morphological traits and 977 expert-validated ant species distributed across the Brazilian Amazon. We produced species range estimates using species distribution models or alpha hulls (when few records were available). Next, we conducted a principal components analysis to combine traits into a space with reduced dimensionality (morphospace). Then, we identified morphologically extreme species in this space and quantified their contributions to morphological diversity across different habitat types in the Brazilian Amazon Basin. We identified 114 morphologically extreme ant species across the Amazon ant morphospace. These species also accounted for a large percentage of morphospace filling, exceeding 99% representation in the most disturbed habitats in the Amazon. Our results suggest that a few morphologically extreme species capture most of the variation in ant morphology and therefore, the spectrum of ecosystem functions performed by ants in the Brazilian Amazon Basin. Further, unlike for many other groups, these extreme morphologies were represented by the set of most common species. These results suggest greater functional redundancy and resilience in Brazilian Amazon ants, but more broadly, they contribute to our understanding of ecological processes that sustain ecosystem functions.</p>

Samples were collected daily over a two-week cycle of a semidiurnal tide range, extending down to 150 m below the mean high tide water level.

Data from: The Amazon Basin's rivers and lakes support Nearctic-breeding shorebirds during southward migration
<p>Shorebird movement data used in habitat analyses for "The Amazon Basin's rivers and lakes support Nearctic-breeding shorebirds during southward migration." Data were collected between 2016-2022 using Argos Platform Terminal Transmitters or Pinpoint GPS Argos transmitters affixed to six shorebird species: American Golden-Plovers (<em>Pluvialis dominica</em>), Hudsonian Godwits (<em>Limosa haemastica</em>), Lesser Yellowlegs (<em>Tringa flavipes</em>), and Buff-breasted (<em>Calidris subruficollis</em>), Pectoral (<em>C. melanotos</em>), and Upland Sandpipers (<em>Bartramia longicauda</em>). The devices were deployed by various research groups at sites outside the Amazon Basin. Data has been subset to the Amazon Basin and the approximate timeframe of southward migration (July-December) and filtered to relevant individuals. </p> <p>The CSV file contains the following variables:</p> <ul> <li> <p>'individual local identifier': a unique alphanumeric identifier for the individual</p> </li> <li> <p>'timestamp': date-time of the location, in YYYY-mm-dd HH:mm:ss format</p> </li> <li> <p>'location.long': longitude</p> </li> <li> <p>'location.lat': latitude</p> </li> <li> <p>'species': shorebird species alpha code</p> </li> <li> <p>'lc': location quality class for Argos PTT (3, 2, 1, 0, A, B, Z) or GPS (G) locations</p> </li> <li> <p>'argos.semi.major': the length of the semi-major axis of the error ellipse for Argos locations, in meters</p> </li> <li> <p>'argos.semi.minor': the length of the semi-minor axis of the error ellipse for Argos locations, in meters</p> </li> <li> <p>'argos.error.radius': one standard deviation (sigma) of the isotropic location error for Argos locations</p> </li> <li> <p>'argos.orientation': the orientation of the semi-major axis of the error ellipse for Argos locations, in degrees clockwise from north</p> </li> <li> <p>'gps.fix.type.raw': the type of GPS fix (2D, 3D)</p> </li> </ul> <p>Links to full studies are provided in 'Related Works.'

dataset for: Fire activity and drought increases ozone-plant damage to the Amazon rainforest.
<h3>Abstract</h3> <div> <p><strong>This dataset relates to work undertaken for publication 'Fire activity and drought increases ozone-plant damage to the Amazon rainforest.'</strong></p> <p><strong>Datasets and jupyter notebooks allow the figures and data to be reproduced.</strong></p> <p> </p> <p><strong>ABSTRACT: </strong>Human activity is exposing the Amazon rainforest to increasing stressors, including plant damage due to elevated ozone (O<sub>3</sub>) pollution. O<sub>3</sub>-plant damage reduces plant photosynthesis and the land carbon sink thus increasing atmospheric CO<sub>2</sub>. Factors that control O<sub>3</sub>-plant damage in the Amazon have not been characterised so damage may be exacerbated by recurrent extreme drought and fires. We identify drivers of interannual variability in O<sub>3</sub>-plant damage using a land surface model validated against satellite products. We find that O<sub>3</sub>-plant damage increases with fire activity, with additional interactive effects during major droughts. The indirect increase in atmospheric CO<sub>2</sub> from fire-driven O<sub>3</sub>-plant damage is ~50% the magnitude of direct CO<sub>2</sub> emissions from fires in non-drought years, suggesting the negative impact of fires on the Amazon carbon budget is severely underestimated. During droughts, leaves close their stomata, which reduces O<sub>3</sub> uptake and should protect against O<sub>3</sub> damage. However, due to higher fire activity, and elevated O<sub>3</sub> concentrations, O<sub>3</sub>-plant damage during droughts is up to 77 Tg-C (or over 2 times) greater than average. As droughts are set to become more frequent, our results demonstrate that high fire activity associated with drought increases the O<sub>3</sub>-plant damage risk to the rainforest, especially in remote areas.</p> </div>
