The Marine Science Institute at University of California Santa Barbara requests continued funding to
maintain research collaborations with The Nature Conservancy (TNC) and U.S. Fish and Wildlife Service
(USFWS) at Palmyra Atoll National Wildlife Refuge (PANWR). Our goal is that high-quality scientific
research and academic rigor are applied to TNC's conservation programs and FWS's management for
Palmyra. Our research objectives are geared towards applied scientific approaches to conservation/
restoration - with information gained at Palmyra applied locally as well as to more impacted reef systems
globally. To this end, we aim to continue close collaborations with colleagues in Moorea, French Polynesia
and reef managers worldwide.
*State the problem and need that this project/program will address.
TNC's newly outlined pillars of conservation, science, and restoration map out an aggressive strategy for
Palmyra to become a global model of reef resilience, rainforest and island conservation, and sustainable
fishing practices. However, this path relies heavily on collaboration with scientific patterns such as those at
UCSB and the lab of Dr. Jenn Caselle. As long-standing collaborators with extensive history in Palmyra (~20
years), we have designed and initiated numerous experiments and projects focused on these objectives.
Continued support will ensure that scientific efforts at Palmyra will be at the highest level and outcomes will
be published and publicly available.
*Project outcomes. Defined as impacts or changes that will be achieved in 1-5 years as a result of your (and
partner) efforts. These may include a policy, human behavior or activity, or state of ecosystem or species.
Our research for the next 3 years at PANWR has 3 foci: 1) animal movement and nutrient redistribution; 2)
herbivory and coral reef resilience; and 3) sustainable fishing practices. All of our research aims to provide
actionable advice to reef managers to improve coral reef health, resilience and fisheries management
practices at Palmyra and globally in the face of climate and small-scale human stressors. The outcome will
be better managed coral reefs.
1) Coral reefs are paradigmatic in that they harbor remarkable levels of diversity and biomass despite
existing in nutrient poor environments. Recent research (including our own) has shown that fish-derived
nutrients (i.e. fish pee) provide significant inputs of nitrogen and phosphorus that support high productivity
on coral reefs. The aggregation and movement patterns of fishes can concentrate and redistribute these
important nutrients within and among reef zones, yet, these pathways are grossly understudied. Our
extensive dataset on animal movements includes more than a dozen species that represent numerous
trophic groups across a range of movement patterns. In this funding period we aim to augment these
movement data and synthesize existing data in order to develop an island-wide movement model of fishderived
nutrient pathways, with a particular focus on nutrient subsidies across habitats and hotspots due to
fish aggregations. This project will potentially 'bust' the global paradigm of how healthy coral reefs exist in
nutrient-depleted oceans and add an under-appreciated motivation for rebuilding fish populations on
2) On coral reefs, herbivores perform the critical function of removing algae that otherwise compete with
corals for space, light, and nutrients. Overfished reefs are transitioning to dominance by algae worldwide,
particularly after disturbance events. Our work in Palmyra aims to understand the role of large herbivores in
coral reef recovery and resilience, with a focus on the fine-scale and large-scale mechanisms that underpin
reef health. During this funding period we will maintain our large-scale herbivore exclusion experiment
(initiated in 2018) and conduct complementary small-scale experiments to test how key ecological process
(e.g. coral predation, coral recruitment) contribute to community reassembly. Our ongoing work impacts
reefs globally by providing reef managers and stakeholders with evidence-based results of the importance

of large, intact herbivore communities that are contextualized by similar, concurrent work being done on the
more impacted reefs of Moorea.
3) In 2018, in collaboration with TNC and building on our long history at Palmyra, we initiated a markrecapture
study employing a small-scale, catch-and-release recreational fishery to assess the stock size
and survival rates for fish species that utilize Palmyra's extensive shallow water and lagoon habitats. This
project is one in our portfolio that most directly informs FWS managers, in fact, they have requested these
data and analyses to better inform a compatibility determination on sport fishing at Palmyra. The
overarching goal of this project goes beyond Palmyra and aims to provide insight for managers worldwide
on best practices for successfully managing similar fisheries, as well as demonstrating the long-term
economic value associated with healthy, intact fish communities.
*Project outputs. Defined as the direct results of short-term (1-2 years) activities undertaken with the Marisla
Foundation grant. These include events, products, or services you create over the duration of the grant period.
Examples include workshops/trainings, reports, meetings with key decision- makers, stakeholder engagements,
Our outputs from this program fall into two categories: programmatic successes for the Palmyra Atoll
research station and its collaborators, and scientific successes related to conservation and management of
coral reefs. Programmatic successes at the end of this funding period will include the well-functioning field
station that supports the collaborative scientific/conservation efforts at Palmyra. This includes frequent
working groups with TNC scientists to design and implement scientific studies and hypothesis testing
around new and ongoing conservation programs at Palmyra. Scientifically, success will be measured by the
extent that our scientific results are published and used to inform conservation and management of Palmyra
and other coral reef system worldwide. Additionally, in this funding period we will maintain collaborations and
host working groups with colleagues in Moorea to continue developing and conducting comparative
experiments in both impacted and unimpacted systems.

Moorea Coral Reef Long Term Ecological Research Program (MCR-LTER) - The Caselle Lab closely
collaborates with Dr. Deron Burkepile and Dr. Thomas Adam of the UCSB Moorea Coral Reef LTER. Current
work includes collaborative reef resilience experiments in Moorea and Palmyra and within the current
funding period we aim to develop an island-wide movement model for fish derived nutrient redistribution
pathways across various habitats.
*Description of potential challenges (internal or external) that your organization may encounter when
implementing this project/program and potential strategies for overcoming them.
At times it can be challenging to apply scientific lessons learned from Palmyra to other, more-impacted
systems across the world due to its remote and largely undisturbed setting. While ecological knowledge
gained in undisturbed systems has intrinsic value, we strive to produce research that can inform
management practices and improve reef health more broadly. To do this we take advantage of studying the
limited disturbances that exist at Palmyra (our experiment studying recovery after a shipwreck and invasive
species) and by contextualizing our results by conducting parallel research with collaborators working in an
impacted system (partnerships within the Moorea LTER).
