{"title":"A new case of communal egg-laying by iguanas and American crocodiles\u0000(Crocodylus acutus Cuvier, 1807) from a Caribbean atoll of Mexico","authors":"P. Charruau, Axel Rissac, David A. Macías Diaz","doi":"10.31611/ch.80","DOIUrl":"https://doi.org/10.31611/ch.80","url":null,"abstract":"Communal egg-laying in oviparous animals occurs when two or more conspecific females deposit their eggs in the same nest cavity (Espinoza & Lobo 1996). Although this behavior appears to be more widespread among reptiles than initially thought (Doody et al. 2009), interspecific communal egg-laying, which involves different reptile species, has been reported less frequently in the literature (Alfonso et al. 2012, Escobedo-Galván et al. 2019). Recently, Escobedo-Galván et al. (2019) published a review of reptile species that have been observed depositing their eggs in crocodile nests. In addition, Platt et al. (2021) provide more information on some reptile species nesting in Crocodylus moreletii and hybrid (C. moreletii x C. acutus) nests in Belize. These studies revealed that interspecific communal egg-laying has been documented for eight (33.3%) of the 24 crocodilian species recognized by the IUCN crocodile specialist group (http://www.iucncsg.org/pages/Crocodilian-Species.html). Among these eight species, three are from the family Alligatoridae (Alligator mississippiensis, Caiman latirostris, and Melanosuchus niger) and five are from the family Crocodylidae (Crocodylus acutus, C. intermedius, C. moreletii, C. novaeguineae, and C. rhombifer) (Escobedo-Galván et al. 2019). There also exist cases of interspecific communal egg-laying in nests of C. acutus x C. moreletii hybrids in Belize (Platt et al. 2021). Twenty-five reptile species have been recorded to deposit their eggs in these crocodile nests: 15 turtles, six lizards, and four snakes (Escobedo-Galván et al. 2019, Platt et al. 2021). Here we report a new case of interspecific communal egg-laying between Crocodylus acutus and iguanas on Cayo Centro, Banco Chinchorro Atoll, Quintana Roo, Mexico. Banco Chinchorro Atoll is a Biosphere Reserve located off the southeastern coast of the Mexican state of Quintana Roo, on the Yucatan Peninsula (see description in Charruau 2021). Cayo Centro is by far the largest cay of the atoll (541 ha) and is located in the center of the reef lagoon (Charruau 2021). Since 2006, we have been monitoring (annually) the reproduction of a recovering population of American crocodiles (Crocodylus acutus) present on this cay (Charruau et al. 2005, 2010, 2013, 2022, Charruau & Hénaut 2012, Charruau 2012). On May 17, 2021, during our annual survey, we found a crocodile nest (18.57°N, -87.33°W) containing 16 iguana eggs beneath 17 C. acutus eggs (Fig. 1). The crocodile nest was a mound (140 cm wide x 150 cm long x 36 cm high) and the substrate consisted mainly of sand with some leaf litter and a black nylon rope (Fig. 2). Crocodile eggs (n = 17) had a mean length of 66.1 ± 2.2 mm (range: 63.2–71.7 mm), mean width of 42.3 ± 0.7 mm (range: 41.2–43.7 mm), and mean mass of 71.5 ± 4.5 g (range: 66.3–84.1 g). Iguana eggs (n = 15) had a mean width of 22.2 ± 0.6 mm (range: 21–23 mm), mean length of 32.1 ± 0.5 mm (range: 31–33 mm), and mean mass of 9.0 ± 0.6 g (range: 7.7–9.9 g).

Michaelides","doi":"10.31611/78","DOIUrl":"https://doi.org/10.31611/78","url":null,"abstract":"In the state of Florida, USA, lizards of the genus Anolis are well represented with at least nine established non-native species and a single native species, A. carolinensis. The most recently introduced species is A. allisoni, a close relative to both the native A. carolinensis and one of the introduced species (A. porcatus). Anolis allisoni is thought to have been present in two locations in Florida since at least 2013 based on photographic evidence. Here, we analyzed mitochondrial DNA (mtDNA) sequences from these three closely related Anolis species to infer the most likely region of origin in the native range and confirm the establishment of the recent invader in Tampa, Florida. We found a single haplotype belonging to A. allisoni, which was closely related to native sequences from east-central Cuba. The most likely geographic origin is a tourist destination in the province of Sancti Spiritus, suggesting the potential for human-mediated introduction of A. allisoni to Florida. Given the evidence of hybridization within the carolinensis subgroup, the presence and establishment of the phylogenetically related and ecomorphologically similar A. allisoni may create novel opportunities for interspecific genetic exchange.","PeriodicalId":344218,"journal":{"name":"Caribbean Herpetology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129831886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advantages of this definition are that it captures nearly all islands with endemic species and with at least some Antillean-derived species, and still circumscribes a region of high biodiversity and biogeographic significance. We argue that Caribbean islands, in this expanded sense, are also cohesive from a conservation standpoint in that they share high human population densities and similar conservation threats. A disadvantage of this definition, strictly applied, is that it includes some islands (e.g., Trinidad) that have mostly mainland species. However, we propose that researchers can increase the stringency of the definition so that it is less inclusive, and make comparisons between different definitions as needed. We provide an updated checklist with standardized common English names for the 1,013 species of amphibians and reptiles occurring in the region, along with principles for constructing common names.","PeriodicalId":344218,"journal":{"name":"Caribbean Herpetology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117041569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schmidt, Nicolas Tirard","doi":"10.31611/CH.65","DOIUrl":"https://doi.org/10.31611/CH.65","url":null,"abstract":"The herpetofauna of Montserrat includes only two snakes, Alsophis manselli and Antillotyphlops monastus, both endemic (Hedges et al. 2009; 2014). Therefore, the discovery of an introduced third species is important, especially when it may pose a threat to the native blindsnake, Antillotyphlops. Here, we report the presence of Indotyphlops braminus, the Brahminy Blindsnake, on Montserrat. One individual, 130 mm in total length, was collected under a rock in the Belham River Valley, Salem (16.74139, -62.21861) in late April 2017 by N. Tirard. It was preserved in ethanol and catalogued into the collection of the New York State Museum (NYSM 6453). This is the first record of that invasive species from Montserrat but it has been documented from other Caribbean Islands: Anguilla, Barbados, Grand Cayman, Grand Turk, Guadeloupe, La Désirade, Martinique, New Providence, Petite St. Vincent, Providenciales, St. Barthélemy, St. Croix, St. Eustatius, St. Kitts, and St. Martin (Powell & Henderson 2012, Lorvelec et al. 2016). Indotyphlops braminus is a triploid obligate parthenogen (Wynn et al. 1987) with a clutch size of 1–8 (Ota et al. 1991). The clutch size of Antillotyphlops monastus is unknown but is probably similar. Given that half of the A. monastus population are females and all I. braminus are females, if all else is equal, I. braminus will produce more offspring than A. monastus. Blindsnakes generally eat ants and termites (Webb et al. 2001) and therefore the two blindsnakes on Montserrat are probably competing for food. Powell et al. (2016) listed the Montserrat blindsnake as “near threatened.” The presence of a competitor that probably reproduces more quickly may further threaten this endemic blindsnake population. For field identification, Indotyphlops braminus usually is very dark dorsally, sometimes appearing black. The Montserrat blindsnake is paler dorsally, often pinkish-tan in coloration. Under magnification, Indotyphlops (Fig 1A) differs in head scalation (Hedges et al. 2014) from Antillotyphlops (Fig. 1B).","PeriodicalId":344218,"journal":{"name":"Caribbean Herpetology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131846007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our report is the furthest south the species has been recorded in the wider Caribbean (CABI Invasive Species Compendium, 2018). On 19 August 2018, one of us (KD) first observed a small population of about five individuals, including an adult male (Fig. 1) near an urban area at La Romain, southwestern Trinidad (10.2498, -61.4861). One of us (DB) caught a juvenile on 26 August 2018 at the same location, and (RJA) brought it to The University of the West Indies Zoology Museum (UWIZM) at the St. Augustine Campus, Trinidad, where it was preserved in 95% ethanol and catalogued (UWIZM.2018.38). Eight other species of Anolis have been reported from Trinidad and Tobago (Murphy et al. 2018), with six of these being introduced to the country; Anolis cristatellus represents the seventh introduced Anolis to Trinidad and Tobago. It can be easily distinguished from all other Anolis on Trinidad by the crest on the tail and body of adult males (Figure 1). Anolis cristatellus has been introduced to countries outside of its native range through human facilitations, such as the transporting of ornamental potted plants (CABI Invasive Species Compendium 2018). The area where we observed the anoles was near the coast, with industrial development nearby. There are two subspecies of Anolis cristatellus and all of those that have been introduced outside of their native range are apparently A. c. cristatellus (Henderson & Powell 2009). Anolis cristatellus has the potential to compete with and displace native and other introduced Anolis species on Trinidad. They occur in both urban and forested areas in their native range and have various attributes that would contribute to being a successful invasive (CABI Invasive Species Compendium 2018). Therefore, the species is considered an ideal organism for studying invasion and adaptation. Tracking and reporting on their distribution can further contribute to knowledge on its invasive and adaptive capabilities.","PeriodicalId":344218,"journal":{"name":"Caribbean Herpetology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134630861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
