There, black spiny-tailed iguanas ( Ctenosaura similis ) one several large invasive reptiles known to occupy burrows imperiled, native gopher tortoise Gopherus polyphemus may even exclude tortoises from their burrows. To test hypothesis burrows, we conducted field study on Gasparilla Island, Florida, USA. We used burrow estimate occupancy each within at sites with without sustained iguana removal efforts modelled co-occurrence patterns between two species. two-species analyses three predictions relating use. Our results support excluded by iguanas. The energetic cost excavating new is unknown but be substantial. In addition, vulnerable extreme temperatures predation while searching for location digging burrow. also show likely effective reducing Other perhaps some typically thought as “burrow commensals” have similar deleterious effects behavior.

The escalating accumulation of petroleum-based polymers has depleted resources and raised environmental concerns due to their non-recyclable non-biodegradable nature. Consequently, there been a growing interest in bio-based plastics, particularly algal-based biopolymers, which offer recyclability eco-friendliness. Algae-derived have distinct advantages, such as autotrophic growth reducing greenhouse gas emissions, rapid rate, low nutritional requirements, resilience harsh environments. Additionally, algae exhibit higher photosynthetic potential (10-20%) compared terrestrial plants (1%-2%). range algal-derived includes alginate, laminarin, fucoidan, carrageenan, agar, ulvan, polyhydroxyalkanoates (PHA), poly-(Hydroxybutyrate) (PHB). However, further efforts are required implement them on large scale. This review highlights algae's raw material for biopolymer production, exploring characteristics applications diverse industries like food pharmaceuticals.

Salvator merianae (Argentine Black and White Tegu, hereafter also ABWT) is a large bodied, omnivorous lizard native to South America. In Florida, where the species was introduced via pet trade invasive, there are at least 3 established populations as well numerous one-off observations. We collected ABWTs from public private property determine their diet in central Florida (Hillsborough County) 2012 2016. determined frequency of occurrence (FO) for items identified various taxonomic levels, calculated niche overlap check an ontogenetic shift diet, evaluated seasonal variation diet. Stomach contents revealed (n = 93) consume fruit, invertebrates, vertebrates, including hatchling Gopherus polyphemus (Gopher Tortoise). Frequency food varied seasonally. Vertebrate prey most common spring, whereas invertebrates plants were consumed frequently summer. Diets among very similar, indicated by Pianka's measure overlap, regardless age or sex. A greater proportion vertebrates compared other invasive (FOcentralFL 81%, FOsouthernFL= 37%, FOBrazil 27%, FOArgentina 44%).

Abstract Invasive species globally threaten biodiversity and economies, but the ecophysiological mechanisms underlying their success are often understudied. For those alien that also exhibit high phenotypic plasticity, such as habitat generalists, adaptations in response to environmental pressures can take place relatively quickly. The Argentine giant tegu ( Salvator merianae ; tegu) is a large omnivorous lizard from South America prolific, long‐lived, vagile, highly adaptable disturbed environments. They well suited climate of southeastern United States, introduced several disjunct areas, including Everglades, where voracious appetite threatens native wildlife. Tegus undergo winter dormancy (hibernation) cope with colder temperatures, while this behavior may facilitate invasion into more temperate regions, it present management opportunities. We studied thermal habits wild S. within invaded range southern Florida, USA. used radiotelemetry trail cameras verify aboveground behaviors, temperature dataloggers monitor surface (sun‐exposed [ T e ] shaded s ]), ambient ), subsurface ground h internal body b ) temperatures population free‐ranging tegus over seasons. evaluated behavioral data identified five biologically significant periods: pre‐hibernal, hibernal, cold snaps, hibernal‐basking, post‐hibernal. found maintained stability throughout hibernal period, frequently at above available microhabitats. Variation was lowest during hibernation snaps less variable than despite not leaving hibernaculum. Hibernal ingress egress were best predicted by differentials between exposed soil daily mean − daylength. Though we detected no sex differences, larger animals started sooner, stayed longer, retained higher fat stores study period. One individual did hibernate, representing only second record behavior. Despite limitations these descriptive data, first finely detailing wild, multiple time periods associate habitats its invasive range. Tegus' apparent ability for expands adaptability breadth underscores threat.
