“…By analyzing the genome of one species against the genomes of other species, it is possible to find species-specific target sequences that could identify that species. Thus, AGE has the potential to identify any two species, especially for closely related species that are difficult to distinguish, which have garnered significant attention, for example, ants [ 40 , 41 , 42 ], butterflies [ 43 , 44 ], bees [ 45 ], spiders [ 46 , 47 ], and fish [ 48 ].…”

Survival crises stalk many animals, especially endangered and rare animals. Accurate species identification plays a pivotal role in animal resource conservation. In this study, we developed an animal species identification method called Analysis of whole-GEnome (AGE), which identifies species by finding species-specific sequences through bioinformatics analysis of the whole genome and subsequently recognizing these sequences using experimental technologies. To clearly demonstrate the AGE method, Cervus nippon, a well-known endangered species, and a closely related species, Cervus elaphus, were set as model species, without and with published genomes, respectively. By analyzing the whole genomes of C. nippon and C. elaphus, which were obtained through next-generation sequencing and online databases, we built specific sequence databases containing 7,670,140 and 570,981 sequences, respectively. Then, the species specificities of the sequences were confirmed experimentally using Sanger sequencing and the CRISPR-Cas12a system. Moreover, for 11 fresh animal samples and 35 commercially available products, our results were in complete agreement with those of other authoritative identification methods, demonstrating AGE’s precision and potential application. Notably, AGE found a mixture in the 35 commercially available products and successfully identified it. This study broadens the horizons of species identification using the whole genome and sheds light on the potential of AGE for conserving animal resources.

“…These species have a high level of interspecific polymorphism (variable body size of workers) and lack intraspecific morphological characters that help in their differentiation (Pitts et al, 2005; Shoemaker et al, 2006; Fox et al, 2012; Pitts et al, 2018). Despite taxonomic lists (see Rossi & Fowler, 2004; Lapola & Fowler, 2008; Fernández et al, 2021) that have recorded S. invicta and S. saevissima , these species can be difficult to identify due to low taxonomic resolution (Kempf, 1961). Most of the time, Solenopsis workers are separated into morphospecies, as done in “ATLANTIC ANTS: a data set of ants in Atlantic Forests of South America” (Silva et al, 2022), which includes 64 nominal species (of the 965 recorded) and 701 morphospecies (of the 5285 recorded).…”

“…Solenopsis (Hymenoptera: Formicidae) comprises 191 species and 22 subspecies of ants (Bolton, 2022). In the Neotropical Region, there are 116 species (Fernández et al, 2021), of which 24 are fire ants (Pitts et al, 2018). Most fire ants are native to South America (Trager, 1991; Pitts et al, 2018) and have a wide geographic distribution (Ascunce et al, 2011; Fernandes et al, 2016; Janicki et al, 2016).…”

Impact of native vegetation cover near crops on the occurrence and molecular diversity of fire ants

Solenopsis invicta and Solenopsis saevissima are the most common fire ants in Brazil. Environmental disturbances favour the colony dispersal of both species, particularly those with an anthropogenic origin. However, the frequencies of the species can vary according to the amount of anthropogenic disturbances. Crops near native vegetation fragments is a common landscape in the Brazilian Atlantic Forest. Here, we analyse if there is influence of native vegetation cover on the occurrence of these fire ants and their molecular diversity in crops. Our hypothesis is that these species are antagonistic in terms of occurrence and molecular diversity when compared in the same habitat. We selected crops near fragments with around 50% of native vegetation cover, a percentage informative enough to detect biological responses from insects belonging to a same order. Nests were collected and the species were identified using external morphology, and mtDNA COI sequences. We reject our hypothesis, which suggest that the species colonize the vegetation patches around crops in a similar way. Solenopsis invicta is not limited by vegetation cover, and has a high haplotype diversity when compared to S. saevissima, particularly when the vegetation cover is greater than 50%. Additionally, the vegetation cover seems to not have influence in the total number of haplotypes, but the species have haplotypes that are exclusive to each landscape. Our findings suggest that S. invicta is expanding to native vegetation areas that it has not occupied before, as S. saevissima was dominant there.

“…The ant fauna collected in the urban fragments of the TDF in the city of Santa Marta represent around 64% of the subfamilies registered for the Neotropics and Colombia, as well as 35% of the genera in Colombia [40]. Of the 84 determined species, 77 were identified at the species level, corresponding to 7% of the current records for the country [40,41].…”

Spatial and temporal variation in the diversity of ants in four urban fragments of the tropical dry forest in the city of Santa Marta was evaluated. The fragments were sampled four times in the dry and rainy season, from October 2019 to January 2020, using pitfall traps, mini-Winkler bags, baits, and manual collection. Both alpha and beta taxonomic diversity and their components were quantified. The functional groups were established based on proposals for Neotropical ant species. A total of 7 subfamilies, 37 genera, and 84 species were collected. Richness varied spatially from 33 to 61 species, but between the two seasons it was 72 and 76 species. Sites N01 and N02 had greater diversity than N03 and N04. In all the fragments, soil ants were dominated by Ectatomma ruidum, but litter ants showed a structure with less dominant species. The dissimilarity between fragments was 60–80%, attributable mainly to turnover (50–70%) but not to nestedness (10%). Seventeen functional groups were identified. Taxonomic diversity of ants in urban fragments in Santa Marta showed marked spatial variation, without influence from the seasons. Despite taxonomic turnover, there was broad similarity in functional groups between the fragments, indicating ecological equivalence of species between the ant assemblages.
