As such, their foraging ecology has been previously studied. However, multiple strong hurricanes have impacted the island reducing the number of natural vines around the cave directly affecting the population of snakes foraging at the cave entrance. We compared the foraging ecology between snakes using natural hunting structures and those using artificial perches provided in Culebrones cave. During March to July of 2021, we performed 30 visits to observe successful hunts and the prey handling time of every individual snake. Observations were repeated during the same period of the following year after the addition of artificial vines. The addition of artificial vines to the entrance of Culebrones cave had a positive effect on the snakes that visited the cave to hunt, observing an increase of three snakes on average per night. Prey handling time was longer when snakes hunted on rock walls when compared to those on vines, suggesting an advantage of vines over rocks as hunting perches. Continued monitoring of the foraging ecology in Culebrones cave should be conducted to determine if the addition of more artificial vines can be beneficial to the snake population at this location.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138950255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of eight species were enumerated on the sand flat: broadleaf panicum (Brachiaria adspersa (Trin.) Parodi), Indian bluegrass (Bothriochloa pertusa (L.) A.Camus), thin paspalum (Paspalum setaceum Michx.), goosegrass (Eleusine indica (L.) Gaertn.), common bermudagrass (Cynodon dactylon (L.) Pers.), southern sandbur (Cenchrus echinatus L.), crowfootgrass (Dactyloctenium aegyptium (L.) Beauv.), and tropical fimbry (Fimbristylis cymosa R.Br.). The greatest Species Relative Density (RD) was observed for Bothriochloa pertusa (76%) and Fimbristylis cymosa (10%), while the RD of all remaining species was ≤ 5%. The Shannon Diversity Index of the sand flat was 0.93, while the Shannon Equitability Index was 0.45, indicating moderate species diversity present within the sand flat. Although all eight species identified were previously reported on the island, characterization of their presence on the sand flat may provide further insights into their conservation significance, potential invasiveness, impacts on the ecosystem, and possible need for management/control. Continued monitoring of Cenchrus echinatus may be highly warranted due to previous documentation as an invasive species capable of displacing native vegetation in tropical regions.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138948373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There remains room for further growth inclusive of primary baseline information, such as determining the identity of flies of forensic importance on the various Caribbean islands. Descriptions of morphology and biology of immature stages of some flies are also lacking, especially for the family Sarcophagidae. Described here is the morphology of the third larval stage of two species of Sarcophagidae of forensic importance, Peckia (Peckia) chrysostoma (Wiedemann, 1830) and Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830). The two species were found to colonise and breed in decomposing pig meat. Specimens collected were reared and dissected using light microscopy. Key larval features are illustrated for use in identification, as an alternative or addition to adult morphology. Structures described include the anterior and posterior spiracle, anal segment, and cephalopharyngeal skeleton. Both species are considered to be of forensic importance and have been shown to colonise human corpses in a review of the literature.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138948957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dada su expansión poblacional en la región, el pez león se ha convertido en una invasión biológica que amenaza el ecosistema marino. El objetivo de este trabajo fue describir algunas características reproductivas básicas de este pez por vez primera para el sureste del golfo frente a la costa norte de la península de Yucatán, México. Las muestras fueron recolectadas a través de un programa de ciencia ciudadana, en el cual los pescadores buzos-langosteros arponearon pez león entre 2010 y 2018. La distribución de frecuencias de talla del pez león fue significativamente diferente entre sexos, con los machos más grandes que las hembras. La proporción en sexos fue signitificativa con predominancia de machos. Los análisis histológicos revelaron que la hembra y macho maduros más pequeños tuvieron 160 mm LT and 196 mm LT, respectivamente. Las hembras alcanzaron una madurez sexual (50%) a una talla menor comparada con los machos. Ambos sexos estuvieron en fase de desove capaz durante todos los meses de muestreo (junio a diciembre), con picos de índice gonadosomático en junio, septiembre y diciembre en las hembras. La estimación del intervalo de desove es cuatro días. En el sureste del golfo, el pez león madura a una talla mayor que el pez león del norte del golfo y el de otras regiones en el Océano Atlántico Oeste, con la excepción de Bermuda. Aunque el tamaño de muestra en nuestro estudio es limitado, la oportunidad para identificar la talla de madurez es útil para establecer una línea base para la historia de vida del pez león en el sureste del golfo.","PeriodicalId":55274,"journal":{"name":"Caribbean Journal of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135635417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
