Tardígrados asociados a una plantación de cítricos de traspatio en la comunidad de El Palmar en Quintana Roo, México

Abstract

El presente estudio provee el registro de tardígrados de líquenes en una plantación de cítricos de traspatio de la comunidad de El Palmar en el estado de Quintana Roo, México. Se proporciona la diagnosis de los géneros Ramazzottius, Mesobiotus y Milnesium. Se discute sobre la riqueza y abundancias de tardígrados en el estado. Se proporciona un cuadro comparativo de los caracteres más relevantes de los tres géneros.

A Strategy to Provide a Present and Future Scenario of Mexican Biodiversity of Tardigrada

“…The colors indicate the taxa recorded, while the different icons symbolize the taxonomic categories: square order, triangle family, and circle genus. Taxa richness is distributed similarly to records: 33 taxa from TVBP, 25 in SMOrP, 17 in YP, 16 in SMOcP, 11 in TP, 11 in VP, 5 in PLP, 4 in ChDP, 4 in BCP, 3 in BBP, 2 in SMSP and 1 in ChHP; while in the marine ecoregions we find 9 taxa in NGM and 2 in CS.The list of recorded Mexican tardigrades and the integration of their national and global distribution is shown in Table 1[25,[34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]87,88,[94][95][96][97][98][99][100][101]. This information allows us to recognize that 58 taxa are present in Mexico, and display a broad distribution in at…”

“…The second one is of Moreno-Talamantes et al [25] in 2019, where 55 species were recognized over eight years, including 11 new records and three previously described species [39,40,45]. Although numerous records were generated in the period 2011-2019 in non-specialized literature, both of genera [34][35][36][37]42,44,87] and species [41,88], these were not included in the latter listing, nor in the calculations of national diversity presented in later works [43,47]. From 2019 onwards the diversity of tardigrades increased notably in Mexico, due to the description of new species [46][47][48][49] and the recognition of new records at the specific and generic level [38,43,47,49].…”

“…Until 2011, the knowledge of tardigrades in Mexico was based on very restricted and occasional sampling, in some cases not even intended to address this taxon, with collections that did not include habitat descriptions and/or distribution patterns at local or regional scales [26][27][28][29][30][31][32]. However, studies over the last 10 years include species listings [33][34][35][36], new records [37][38][39][40][41][42][43][44], and descriptions of new species [45][46][47][48][49]. The results of these researchers suggest that, by the year 2021, in Mexico, more than 70 tardigrade species were recognized, and most of them are limnoterrestrial moss dwellers [43] and to a lesser extent marine species.…”
