Invasive plants can cause drastic changes in their new ecosystems, and these changes might depend also on future climatic conditions. Buffelgrass is an African C4 bunchgrass that has been introduced outside its native range for rangeland improvement and livestock feed. In the Caribbean region, it has been introduced to supplement managed pasturelands and can have an effect on the surviving native flora. To determine the potential range where these populations might be present in tropical dry forest biomes in the next decades, we ran species distribution models for the Puerto Rican bank. We found that buffelgrass will remain present in the tropical dry forest biome of the main island of Puerto Rico as well as nearby islands with equal or greater biodiversity refuges. With the increase in atmospheric greenhouse gases, more areas of Puerto Rico's coasts and nearby islands will become suitable habitat for this invasive grass. Those areas should be actively monitored for control and removal of this invasive grass.

Abstract The ant fauna in natural and rural areas of Jamaica has received substantial interest in the past. However, no recent works have focused primarily on the ants of urban and suburban areas. In this study, we assessed the species richness and origin of ants in urban and suburban areas of St. Andrew, Jamaica. Ant specimens were hand-collected within a 30 m radius area during a 15 minute search conducted at 27 sample sites during 39 sampling events. A total of 31 ant species were collected, representing a mixture of 18 native (58.1%) and 13 introduced (41.9%) species. Among the 18 species native to the Caribbean region, three (9.7%) are endemic to Jamaica, namely Camponotus hannani, Camponotus fugax, and Cephalotes jamaicensis. Sixteen tramp species (species with a worldwide distribution) represented 51.6% of the ant community, including Brachymyrmex patagonicus, Nylanderia steinheili, Paratrechina longicornis, Tapinoma melanocephalum, and Trichomyrmex destructor. Brachymyrmex patagonicus, Solenopsis geminata, and P. longicornis were most prevalent, being respectively found at 92.6%, 85.2%, and 81.5% of the sampled sites. Brachymyrmex obscurior, Camponotus fugax, Camponotus sexguttatus, Crematogaster steinheili, and Pheidole subarmata were among the least prevalent, each found at only one site. This publication presents the first published records of Solenopsis globularia and Monomorium pharaonis in Jamaica, with short descriptions of their habitats. The urban and suburban ant community of St. Andrew presents a relatively high species richness.

Abstract This study presents the first scanning electron microscopy investigation of the antenna of adult Bahamiola orbitalis, a species of potential forensic relevance. The specimens used in the analysis were obtained from traps baited with decomposing chicken in Jamaica, and 16 males were used in the morphometric analysis of the species. The antennae of B. orbitalis exhibit the typical characteristics of cyclorrhaphan Diptera, with the scape, the pedicel, and the postpedicel that bears the arista. The distribution, number, and location of sensilla on the antennae are described. Five types of sensilla were observed. The scape and pedicel have only chaetic sensilla, the postpedicel bears trichoid, basiconic, coeloconic sensilla, and clavate sensilla. Basiconic sensilla were the most numerous sensilla found on the antennae. Coeloconic sensilla are short-pegged and located in sunken depressions. The ventral surface of the postpedicel bears one sensory pit. This study provides additional information about the structure of the antennae in Sarcophagidae. This can be used to compare evolutionary relationships and identify shared characteristics.

Abstract Patterns and body coloration have multiple functions in animals, including in social behavior. Bird coloration is affected by several factors which can result in several types of color aberrations, most being caused by genetic mutations. Although they have not been systematically quantified across multiple species and populations, chromatic disorders in birds are presumably rare. Brown is the most common heritable aberration, and Progressive Greying is the most common aberration in general, although most forms are not straight forward heritable. There is much confusion in the literature among types of aberrations, especially regarding white birds. The Broad-billed Motmot, Electron platyrhynchum, is found from Honduras to Western Ecuador, Central Bolivia, and Central Brazil, generally below 1,100 m. It inhabits mature wet forests and older secondary growth. As a result of a casual observation, a juvenile, white Broad-billed Motmot was detected on October 14, 2022 at the Anura Amphibian Conservation Farm in San Ramón, Costa Rica. The beak and feet of this bird were normal colored, which indicate that the white plumage is not the result of Leucism. Also, the motmot had normal colored eyes, so it is not an Albino. Here we report this case and discuss on key aspects of chromatic disorders in birds.
