A Monarch Butterfly Summit was held June 22-23 at the Capitol in Washington D.C. to discuss western monarch conservation. The summit was organized by Senator Jeff Merkley (OR) and attended by Secretary of the Interior Deb Haaland, Senators Ron Wyden (OR) and Alex Padilla (CA), Congressperson Jimmy Panetta (CA), Assistant Secretary for Fish and Wildlife and Parks Shannon Estenoz, and U.S. Fish and Wildlife Service (FWS) Director Martha Williams. Scientific presenters included Amanda Barth (Western Monarch and Native Pollinator Working Group), Wendy Caldwell (Monarch Joint Venture), Ryan Drum (USFWS) and Wayne Thogmartin (USGS), Cat Darst (USFWS), Cheryl Schultz (Washington State University), Matt Forister (University of Nevada – Reno), Louie Yang (University of California – Davis), Sarah Hoyle (Xerces Society for Invertebrate Conservation), Francis Villablanca (Cal Poly State University), Elizabeth Crone (University of California – Davis), and Sarina Jepsen (Xerces Society for Invertebrate Conservation).

The Department of the Interior announced a $1 million dollar award to the National Fish and Wildlife Foundation’s (NFWF) Monarch Butterfly and Pollinators Conservation Fund, and the Fish and Wildlife Service announced a Pollinator Conservation Center. In addition, two bills to support the Monarch Action, Recovery, and Conservation of Habitat (MONARCH) Act and the Monarch and Pollinator Highway Act were proposed last year; if passed, these acts would support a variety of initiatives focused on monarch research and conservation.

We are very excited that Zoe Wood and Calvin Carroll will be joining the lab this year! Zoe will be a Ph.D. student in the Graduate Group in Ecology and Calvin will be a Ph.D. student in the Population Biology Graduate Group starting in the fall. Welcome!

The Bilinski Fellowship supports “interdisciplinary, innovative, and highly collaborative” projects at the Bodega Marine Laboratory. Projects must “bridge the natural sciences, social sciences, and/or humanities”. Tracie’s project will support her continued research into the ecology of carrion beetles on ephemeral resource patches, and a collaborative in situ art exhibition along Mussel Point trail at the Bodega Marine Reserve.

Elizabeth Postema received  one of twelve $10,000 scholarships from Phi Beta Kappa, the nation’s oldest academic honor society. In addition, Elizabeth also received a separate research grant from the 2022 Maurer-Timm Endowment to support her project “Effects of temperature-induced color plasticity on warning signals in pipevine swallowtail larvae (Battus philenor)”.

Abstract

1. To evaluate how increased anthropogenic nutrient inputs alter carbon cycling in grasslands, we conducted a litter decomposition study across 20 temperate grasslands on three continents within the Nutrient Network, a globally distributed nutrient enrichment experiment

2. We determined the effects of experimental nitrogen (N), phosphorus (P), and potassium plus micronutrient (K_μ) additions on decomposition of a common tree leaf litter in a long-term study (maximum of 7 years; exact deployment period varied across sites). The use of higher-order decomposition models allowed us to distinguish between effects of nutrients on early- versus late-stage decomposition.

3. Across continents, addition of nitrogen (but not other nutrients) accelerated early-stage decomposition and slowed late-stage decomposition, increasing the slowly decomposing fraction by 28% and the overall litter mean residence time by 58%.

4. Synthesis. Using a novel, long-term cross-site experiment, we found widespread evidence that nitrogen enhances the early stages of aboveground plant litter decomposition across diverse and widespread temperate grassland sites, but slows late-stage decomposition. These findings were corroborated by fitting the data to multiple decomposition models and have implications for nitrogen effects on soil organic matter formation. For example, following nitrogen enrichment, increased microbial processing of litter substrates early in decomposition could promote production and transfer of low molecular weight compounds to soils, and potentially enhance stabilization of mineral-associated organic matter. By contrast, by slowing late-stage decomposition, nitrogen enrichment could promote particulate organic matter (POM) accumulation. Such hypotheses deserve further testing.

Abstract

Nature-based tourism has potential to sustain biodiversity and economic development, yet the degree to which biodiversity drives tourism patterns, especially relative to infrastructure, is poorly understood. Here, we examine relationships between different types of biodiversity and different types of tourism in Costa Rica to address three questions. First, what is the contribution of species richness in explaining patterns of tourism in protected areas and country-wide in Costa Rica? Second, how similar are the patterns for birdwatching tourism compared to those of overall tourism? Third, where in the country is biodiversity contributing more than other factors to birdwatching tourism and to overall tourism? We integrated environmental data and species occurrence records to build species distribution models for 66 species of amphibians, reptiles, and mammals, and for 699 bird species. We used built infrastructure variables (hotel density and distance to roads), protected area size, distance to protected areas, and distance to water as covariates to evaluate the relative importance of biodiversity in predicting birdwatching tourism (via eBird checklists) and overall tourism (via Flickr photographs) within Costa Rica. We found that while the role of infrastructure is larger than any other variable, it alone is not sufficient to explain birdwatching and tourism patterns. Including biodiversity adds predictive power and alters spatial patterns of predicted tourism. Our results suggest that investments in infrastructure must be paired with successful biodiversity conservation for tourism to generate the economic revenue that countries like Costa Rica derive from it, now and into the future.

Abstract

Projecting species’ responses to climate change at continental scales is a current “grand challenge” of ecological research. Insects are sensitive indicators of both climate and land-use change and recent studies indicate widespread declines in many geographic regions. To predict changes across entire ranges, a variety of species distribution models have been developed, but rarely account for regional variability, ecological interactions or a species’ potential to adapt to changing conditions. This project spans multiple institutions situated in the United States’ southwest, polar north, and temperate eastern regions. A series of physiological experiments will be implemented for five widespread butterfly species with populations sourced from different biomes within each of their ranges. Caterpillars will be subjected to a range of conditions mimicking past, current and future climates. Their development rate, survivorship, immune response, and genetic structure and gene expression (which genes are actively coding for proteins) will be measured and used to build models that predict distributional shifts. Data collected by community (“citizen”) scientists will be used to validate the models. This project requires substantial cross-disciplinary collaboration, and a central goal is to recruit diverse trainees at the graduate and undergraduate levels and train them in the “science of team science”. Project trainees will develop independent research ideas that align with and expand the project’s scope and travel between and work at collaborating institutions as an inter-lab exchange to learn new techniques and be exposed to different research philosophies. Finally, the project has significant management implications for insect biodiversity conservation.
