From global trends to local microclimates: Assessing NOAA Coral Reef Watch alerts and ECOSTRESS thermal imagery in Belize

Ileana A. Callejas, Christine Lee, Charis E. Adams

Coral reefs are vital global ecosystems and are severely impacted by rising ocean temperatures, culminating in four global bleaching events, including the most recent in 2023-2024. This study employs a multi-scale nested analysis approach, combining observed bleaching and satellite thermal stress alerts …

The influence of urbanization and water reclamation plants on fecal indicator bacteria and antibiotic resistance in the Los Angeles River watershed: A case study with complementary monitoring methods

Ileana A. Callejas, Yuwei Kong, Katie E. Osborn, Wei-Cheng Hung et autres

Urban land use and water reclamation plants (WRPs) can impact fecal indicator bacteria (FIB) and antimicrobial resistance (AMR) in coastal watersheds. However, there is a lack of studies exploring these effects on the US West Coast. Additionally, there is limited research using …

Spatio-Temporal Dynamics of Total Suspended Sediments in the Belize Coastal Lagoon

Chintan B. Maniyar, Megha Rudresh, Ileana A. Callejas, Katie E. Osborn et autres

Increased tourism in Belize over the last decade and the growth of the local population have led to coastal development and infrastructure expansion. Land use alteration and anthropogenic activity may change the sediment and nutrient loads in coastal systems, which can negatively …

Use of Google Earth Engine for Teaching Coding and Monitoring of Environmental Change: A Case Study among STEM and Non-STEM Students

Ileana A. Callejas, L Huang, Marisol Cira, Benjamin Croze et autres

Computational skills are advantageous for teaching students to investigate environmental change using satellite remote sensing. This focus is especially relevant given the disproportionate underrepresentation of minorities and women in STEM fields. This study quantified the effects in both a STEM and a …

A GEE toolkit for water quality monitoring from 2002 to 2022 in support of SDG 14 and coral health in marine protected areas in Belize

Ileana A. Callejas, Katie E. Osborn, Christine Lee, Deepak R. Mishra et autres

Coral reefs are highly diverse ecosystems that provide many goods and ecosystem services globally. Coral reef ecosystems are also threatened by environmental stressors from anthropogenic sources and shifting climates. The United Nations Sustainable Development Goal 14 (“Life Below Water”) addresses the need …

Modeled Impacts of LULC and Climate Change Predictions on the Hydrologic Regime in Belize

Vanesa Martín-Arias, Christine E. Evans, Robert Griffin, Emil Cherrington et autres

Land use and land cover (LULC) change can have detrimental effects on water quality. In Belize, agricultural expansion creates the risk of increased sediment load and excess nutrients in runoff water, while deforestation removes potential infiltration sites for this outflow. Climate change …

Kinetic Properties of Microbial Exoenzymes Vary With Soil Depth but Have Similar Temperature Sensitivities Through the Soil Profile

Ricardo Eloy Alves, Ileana A. Callejas, Gianna L. Marschmann, Maria Mooshammer et autres

Current knowledge of the mechanisms driving soil organic matter (SOM) turnover and responses to warming is mainly limited to surface soils, although over 50% of global soil carbon is contained in subsoils. Deep soils have different physicochemical properties, nutrient inputs, and microbiomes, …
