Palm species richness, abundance and diversity in the Yucatan Peninsula, in a neotropical context

Autonomous reef monitoring structures (ARMS) have been proposed as a standardized, passive, nondestructive sampling tool. This study assessed the ability of ARMS to capture the cryptic species diversity of two coral reefs by recording species richness and taxonomic representativeness using conventional taxonomy. The capacity of ARMS, as artificial substrates, to favor the establishment of nonindigenous species over native species was also evaluated. The use of ARMS allowed the detection of 370 species morphotypes from nine phyla, yielding 13 new records of geographic distribution expansion, one exotic species for the Gulf of México and the Caribbean Sea, and six newly described species. It was also possible to make spatial comparisons of species richness between both reefs. ARMS captured cryptic diversity exceptionally well, with the exception of echinoderms. Furthermore, these artificial structures did not hinder the colonization ability of native species; in fact, the colonization patterns on the structures themselves represented the spatial differences in the structure of benthic assemblages. This study represents the first effort to make a conventional taxonomic description of the cryptic fauna of the Yucatan Peninsula using ARMS. It is recommended to assess coral reef species diversity, but more taxonomists specialized in marine invertebrates are needed.

Abstract A study was carried out to determine Sarcophagidae diversity attracted to the different stages of decomposition of a Boa constrictor cadaver during late winter in the Yucatan Peninsula. As a result of this study, seven species of Sarcophagidae were documented, Oxysarcodexia conclausa (Walker, 1861) (Diptera: Sarcophagidae), Peckia (Euboettcheria) volucris (Wulp, 1895) (Diptera: Sarcophagidae), Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830) (Diptera: Sarcophagidae), Oxysarcodexia amorosa (Schiner, 1868) (Diptera: Sarcophagidae), Ravinia derelicta (Walker, 1853) (Diptera: Sarcophagidae), Ravinia effrenata (Walker, 1861) (Diptera: Sarcophagidae), and Titanogrypa (Cucullomyia) placida (Aldrich, 1925) (Diptera: Sarcophagidae), The last five species listed are the first documentation of their presence in the Yucatan Peninsula in Mexico. Sarcophagids were present throughout the decomposition process; however, the greatest abundance and diversity of this family were present during the advanced decay stage. This is the first work on flesh flies in the region and the first in the country that has focused on wildlife.

AbstractAlthough the genusGracilariais well represented on the Mexican coasts, there are few studies focused on the taxonomic aspects and the clarification of the relationships between species. The high morphological plasticity exhibited by several of its representatives could underestimate the true species richness. In the present study, a group of cylindrical specimens ofGracilariafrom the southeastern Gulf of Mexico, previously identified asG. cornea, was collected. Based on COI-5P andrbcL sequences, these samples formed an independent group closely related toG. ferox, a flat species. Morphologically, our specimens differed fromG. feroxand the other species ofGracilariaby the presence of very small cystocarps and a thick pericarp composed of many layers of cells. We proposeGracilaria microcarpasp. nov. as the name for this group of cylindrical specimens from the Yucatan Peninsula of Mexico.

Objective. To analyze the valuation, use, and preservation of native palms as a non-timber forest product (NTFP) of high economic importance for rural communities in the Yucatán Peninsula, Mexico. Design/methodology/approach: The available literature on palms and their use in the Yucatán Peninsula (YP) was examined using the snowball method. Subsequently, different online flora databases were consulted in order to examine the taxonomic identities of palm species present in the YP. The reported uses were classified. Results: The YP has 20 native species that belong to 13 genera and three subfamilies. All of them are economically exploited as NTFPs, especially in construction (85%) and honey production (70%), followed by food and medicinal use (35% each), craftwork (30%), ornamental use (25%), and fodder (10%). These data confirm that native palms are an important livelihood means for the inhabitants of Mayan communities in the region. Study limitations/implications: The research faced a limited database of encyclopedias, anthologies, directories, books, or articles that interpret works or research about this topic. Findings/Conclusions: The local and regional use of palms represents an additional income for the people who use this natural resource on different productive scales, both in rural communities and city centers. An alternative to ensure the sustainability of palms would be to establish governmental programs for their reproduction

Integrating information about the spatial distribution of carbon stocks and species diversity in tropical forests over large areas is fundamental for climate change mitigation and biodiversity conservation. In this study, spatial models showing the distribution of carbon stocks and the number of species were produced in order to identify areas that maximize carbon storage and biodiversity in the tropical forests of the Yucatan Peninsula, Mexico. We mapped carbon density and species richness of trees using L-band radar backscatter data as well as radar texture metrics, climatic and field data with the random forest regression algorithm. We reduced sources of errors in plot data of the national forest inventory by using correction factors to account for carbon stocks of small trees (<7.5 cm DBH) and for the temporal difference between field data collection and imagery acquisition. We created bivariate maps to assess the spatial relationship between carbon stocks and diversity. Model validation of the regional maps obtained herein using an independent data set of plots resulted in a coefficient of determination (R2) of 0.28 and 0.31 and a relative mean square error of 38.5% and 33.0% for aboveground biomass and species richness, respectively, at pixel level. Estimates of carbon density were influenced mostly by radar backscatter and climatic data, while those of species richness were influenced mostly by radar texture and climatic variables. Correlation between carbon density and species richness was positive in 79.3% of the peninsula, while bivariate maps showed that 39.6% of the area in the peninsula had high carbon stocks and species richness. Our results highlight the importance of combining carbon and diversity maps to identify areas that are critical—both for maintaining carbon stocks and for conserving biodiversity.

Malaise Traps

A study on abundance and diversity of Hymenoptera was conducted in Gunung Datuk, Rembau. Samplings were conducted from November 2014 to February 2015 using six Malaise traps. Three traps were placed at Site 1 at 700m height for high elevation and the remaining traps were placed at Site 2 at 200m height for low elevation. A total number of 221 Hymenopteran were collected which consist of nine families namely Ichneumonidae, Formicidae, Braconidae, Bethylidae, Evaniidae, Tiphiidae, Vespidae, Pompilidae and Apidae. In this study, 93 individuals were obtained from Site 1, comprising nine families and 43 morphospecies while 127 individuals were obtained from Site 2 with nine families and 45 morphospecies. Formicidae was the most dominant family collected from both sites with a total of 104 individuals while the least family recorded was Apidae with only one individual. Shannon’s Weiner Diversity Index (H’) showed Site 1 had the higher diversity value with H’ = 3.17 compared to Site 2 with value H’ = 3.12. For Evenness Index, Site 1 had higher value compared to Site 2 with E’ = 0.84 and E’ = 0.82 respectively. Moreover, for Margalef Richness Index, Site 1 recorded R’ = 9.24 while site two recorded R’ = 9.08 which concluded that Site 1 had higher species richness compared to Site 2. Paired t-test showed that both sites had no significant difference with p>0.05. Overall study showed that the diversity and abundance of Hymenoptera in Gunung Datuk were low since the value of H’ is less than 3.50.
