Comparative life history of mud turtles (genus: Kinosternon) from the North American deserts Comparative life history of mud turtles (genus: Kinosternon) from the North American deserts
The warm deserts of North America are characterized by diverse environments that include the transition zone between tropical and temperate regions on the continent. This vast region includes the Sonoran and Chihuahuan deserts, which have different precipitation regimes and are composed of different floras and faunas, separated by the Cochise Filter Barrier. Inhabiting these deserts are...

Insight 4. Climate change and biodiversity loss amplify each other Insight 4. Climate change and biodiversity loss amplify each other
Key messages: • Climate change is impacting biodiversity from local to global scales, and growing evidence suggests that further loss of biodiversity can contribute to climate change, creating a destabilizing feedback. • Loss of plant diversity due to climate and land-use change can weaken ecosystem functioning, leading to a decrease in biomass accumulation and reduced carbon storage. •...

Earthquake stress-drop values delineate spatial variations in maximum shear stress in the Japanese forearc lithosphere Earthquake stress-drop values delineate spatial variations in maximum shear stress in the Japanese forearc lithosphere
Earthquake stress drop (Δσ) may increase with depth and stress in the brittle lithosphere. However, the range of uncertainty in Δσ and the lack of constraints on absolute stress make it difficult to establish whether they are correlated. Here, we investigate Δσ dependence on depth and maximum shear stress (τmax) based on ~11 years of seismicity in the northeastern Japanese forearc...

Aftershocks in stress shadows are inconsistent with modeled static Coulomb stress changes Aftershocks in stress shadows are inconsistent with modeled static Coulomb stress changes
Aftershock triggering is commonly attributed to increases in static Coulomb stress. In some areas, termed "stress shadows", a decrease in Coulomb stress is predicted to suppress earthquake occurrence. However, aftershocks are often observed in the modeled stress shadows. We examine several hypotheses that attempt to reconcile these shadow aftershocks with the static Coulomb stress change...

Nodal seismic deployment on Mauna Loa volcano, Hawaii: Dataset and preliminary insights Nodal seismic deployment on Mauna Loa volcano, Hawaii: Dataset and preliminary insights
Mauna Loa is the largest active volcano on Earth, comprising ∼51% of the Island of Hawai‘i’s landmass and posing significant risks to the island’s communities, infrastructure, and natural environment. Historical eruptions have produced lava flows that have reached the ocean in as little as 3 hr. The timing and location of such lava flows in the past 200 yr underscore how critical...

Climatological effects on survival, recruitment, and possible extirpation of a Sierra Nevada anuran Climatological effects on survival, recruitment, and possible extirpation of a Sierra Nevada anuran
The drivers of population dynamics are a primary interest of ecologists, and predicting the consequences of climate variability on wildlife populations benefits from an understanding of how weather causes variation in the vital rates of populations. Given recent and projected extremes in annual precipitation in the Sierra Nevada of California, USA, including two severe droughts, we...

Apparent annual survival of adult Golden-winged Warblers (Vermivora chrysoptera) may not differ by sex or region Apparent annual survival of adult Golden-winged Warblers (Vermivora chrysoptera) may not differ by sex or region
Understanding range-wide demographic, spatial, and temporal variation in annual survival is essential for managing species of conservation concern. Multi-population models are useful tools for integrating diverse datasets, reducing biases, and deriving survival estimates across differing spatial scales. We conducted a range-wide, multi-population apparent annual survival analysis for a...

A generalized design flood estimation framework under stationary and non-stationary scenarios A generalized design flood estimation framework under stationary and non-stationary scenarios
With the ever-ongoing debate over the death of stationarity in flood time series, developing methods for flood frequency analysis that can address both stationarity and non-stationarity simultaneously has become increasingly important for design flood estimation. Existing non-stationary flood frequency analysis (NFFQ) methods are either limited to providing time-varying conditional flood...

Application of fin tissue for nonlethal stable isotope analysis of small-bodied fishes Application of fin tissue for nonlethal stable isotope analysis of small-bodied fishes
Stable isotopes are commonly used to characterize food web structure and resource use by aquatic organisms. White muscle is generally preferred for stable isotope analysis of fishes. However, obtaining white muscle tissue typically requires lethal take or invasive sampling techniques, which are undesirable for small-bodied species or those of conservation concern. We assessed the use of...

Recovery of Delaware Bay horseshoe crabs following harvest reductions Recovery of Delaware Bay horseshoe crabs following harvest reductions
Objective Horseshoe crabs Limulus polyphemus play a vital role in the Delaware Bay ecosystem. The migratory stopover of several shorebird species occurs during the horseshoe crab spawning season, and the eggs of horseshoe crabs provide an essential food source to fuel their northward migration to breeding areas. High commercial fishery use of horseshoe crabs as bait during the 1990s...
