Exploring Marine Ecosystems and Native Plants: Insights from Coral Reefs to Backyard Gardens
The coral microbiome is a powerful mechanism for resiliency with significant capacity to protect its host from pathogens, parasites, toxins, eutrophic waters, heat stress, and bleaching. This study will investigate whether heat tolerant coral species that retain their beneficial microbiome during a heat stress event can aid less heat tolerant species in recovering beneficial microbiome members via horizontal transmission during or post-heat stress.
The purpose of this study was to identify a bacterial sample collected from a local storm water reservoir using the 16S rRNA gene to identify it. The genetic sequence was then used to explore the evolutionary relationships of the identified bacteria. A freshwater sample from Lake Pasadena was cultured, and DNA was extracted from a selected colony. The 16S rRNA gene was amplified via PCR and confirmed by gel electrophoresis (~1500 bp). Sequencing and BLAST analysis identified the bacterium as Acinetobacter johnsonii. Phylogenetic analysis using MEGA11 placed it within a eurytopic group of Gammaproteobacteria, capable of surviving diverse environments. Sub-tree groupings highlight habitat adaptability and catalase activity as a key ecological trait.
Invasive species are a significant source of biodiversity loss in a given habitat. This is largely because they can quickly reach high population levels and outcompete native individuals. This rapid population growth will usually result in significant, harmful overall impact on ecosystems. This study examines the population density factors of the invasive Indo-Pacific red lionfish… Continue reading Are invasive Lionfish affected by population density?
This summer I got to take my niece and nephew shark tooth hunting at Caspersen Beach in Florida. Caspersen beach is renowned for its abundance of fossilized shark teeth, and as such, is a popular destination for fossil hunters.
As the effects of climate change increase, organizations throughout the the Florida keys have ramped up their restoration efforts. However, without identifying heat-tolerant coral genomes, these restoration efforts cannot succeed. Heat-tolerant corals are crucial to conservation efforts for a number of reasons including; outplanting more resilient corals in restoration projects, selective breeding projects, and understanding the evolutionary potential of this coral species. This paper presents research findings on tests conducted to measure heat tolerance of Staghorn Coral (Acropora Cervicornis) that is critically endangered and a focal species for most restoration efforts in the Florida Keys.
