Invasive grass (Microstegium vimineum) indirectly benefits spider community by subsidizing available prey

Andrew Landsman, Karin Burghardt & Jacob Bowman
1. Invasive plant species cause a suite of direct, negative ecological impacts, but subsequent, indirect effects are more complex and difficult to detect. Where identified, indirect effects to other taxa can be wide-ranging and include ecological benefits in certain habitats or locations. 2. Here, we simultaneously examine the direct and indirect effects of a common, invasive grass species (Microstegium vimineum) on the invertebrate communities of understory deciduous forests in the eastern United States. To do...

Haemosporidian parasites of Neotropical birds: causes and consequences of infection

Vincenzo A. Ellis, Alan Fecchio & Robert E. Ricklefs
Haemosporidian parasites of the genera Plasmodium, Haemoproteus, and Leucocytozoon are among the best studied parasites of Neotropical birds. Here, we describe variation in haemosporidian prevalence (i.e., the proportion of infected birds in a sampled population) in Neotropical birds. We review correlates of haemosporidian prevalence (including several avian life-history traits, climate, and season) and the population and evolutionary consequences of infection for Neotropical birds. We find that prevalence varies among avian taxonomic families, genera, and even...

Data from: Shark movement strategies influence poaching risk and can guide enforcement decisions in a large, remote Marine Protected Area

David Jacoby, Francesco Ferretti, Robin Freeman, Aaron Carlisle, Taylor Chapple, David Curnick, Jonathan Dale, Robert Schallert, David Tickler & Barbara Block
Large, remote marine protected areas (MPAs) containing both reef and pelagic habitats, have been shown to offer considerable refuge to populations of reef-associated sharks. Many large MPAs are, however, impacted by illegal fishing activity conducted by unlicensed vessels. While enforcement of these reserves is often expensive, it would likely benefit from the integration of ecological data on the mobile animals they are designed to protect. Consequently, shark populations in some protected areas continue to decline,...

Evasion of plant innate defense response by Salmonella on Lettuce

Nicholas Johnson, Harsh Bais, Kalmia Kniel & Pushpinder Kaur Litt
To establish host association, the innate immune system, which is one of the first lines of defense against infectious disease, must be circumvented. Plants encounter enteric foodborne bacterial pathogens under both pre- and post-harvest conditions. Human enteric foodborne pathogens can use plants as temporary hosts. This unique interaction may result in recalls and illness outbreaks associated with raw agricultural commodities. The purpose of this study was to determine if Salmonella enterica Typhimurium applied to lettuce...

Retreat of Humboldt Gletscher, North Greenland, driven by undercutting from a warmer ocean

Eric Rignot, Lu An, Nolwenn Chauché, Mathieu Morlighem, Seongsu Jeong, Michael Wood, Jeremie Mouginot, Joshua Willis, Ingo Klaucke, Wilhelm Weinrebe & Andreas Muenchow
Humboldt Gletscher is a 100-km wide, slow-moving glacier in north Greenland which holds a 19-cm global sea level equivalent. Humboldt has been the fourth largest contributor to sea level rise since 1972 but the cause of its mass loss has not been elucidated. Multi-beam echo sounding data collected in 2019 indicate a seabed 200 m deeper than previously known. Conductivity temperature depth (CTD) data reveal the presence of warm water of Atlantic origin at 0°C...

A place to land: spatiotemporal drivers of stopover habitat use by migrating birds

Emily Cohen, Jeffrey Buler, Kyle Horton, Andrew Farnsworth, Peter Marra, Hannah Clipp, Jaclyn Smolinsky & Daniel Sheldon
Migrating birds require en route habitats to rest and refuel. Yet habitat use has never been integrated with passage to understand factors that determine where and when birds stopover during spring and autumn migration. Here, we introduce the stopover-to-passage ratio (SPR), the percentage of passage migrants that stop in an area, and use eight years of data from 12 weather surveillance radars to estimate over 50% SPR during spring and autumn through the Gulf of...

Habitat openness and edge avoidance predict saltmarsh sparrow abundance better than habitat area

Hallie Marshall, Erik Blomberg, Valerie Watson, Meaghan Conway, Jonathan Cohen, Maureen Correll, Chris Elphick, Thomas Hodgman, Alison Kocek, Adrienne Kovach, W. Gregory Shriver, Whitney Wiest & Brian Olsen
The Saltmarsh Sparrow (Ammospiza caudacuta) is a tidal marsh bird facing rapid population decline throughout its range, largely caused by degradation and loss of breeding habitat. Thus there is a need to preserve tidal marshes in the northeastern United States, but to do so requires an understanding of the habitat features that support robust populations. Previous studies have shown Saltmarsh Sparrow abundance increases with marsh size, but in similar bird species, area sensitivity is more...
