Genetic diversity of Horsfieldia tetratepala (Myristicaceae), an endangered plant species with extremely small populations to China: implications for its conservation
<p>Genetic variation determines the evolutionary potential of a species and is vital for fully understanding the evolution of a species, as well as for developing optimal conservation strategies. <i>Horsfieldia tetratepala</i> is an economically important rainforest tree which has declined steadily, mainly though habitat destruction, and an endangered, narrow endemic in China where it is also classified as a Plant Species with Extremely Small Populations (PSESP). Effective conservation strategies for <i>H. tetratepala</i> are required urgently, but limited information about its<i> </i>genome is available. Accordingly, restriction site-associated DNA sequencing (RAD_seq) was used to sequence sixty-three <i>H. tetratepala</i> trees covering ten isolated populations to assess genome-level diversity and population structure, generating 8,103 high-quality SNPs. Low genetic diversity and moderate genetic differentiation was observed among populations, but Bayesian clustering divided the sampled <i>H. tetratepala</i> populations into two genetic clusters, though with some populations from Guangxi and Yunnan intermixed. Because of increasing of habitat fragmentation and human disturbance, conservation priority should be placed on populations with higher genetic variation (e.g., BB, TKH, DWS, and GLQ). Overall, our study provides valuable genomic resources for <i>H. tetratepala</i> that will significantly advance the formulation of effective conservation strategies.</p>

Figure 4 AIguana insularis sanctaluciae hatchlings (northeast Saint Lucia) B hatchling I. insularis insularis (IGU143, Union Island, Grenadines). The I. insularis hatchlings in both A and B show strong dark green to light green banding on the body and the tail, with a white mark at the scapular level C hatchlings alien I. rhinolopha in Florida. These iguanas have a nearly uniform green body with only some brown narrow banding on the body.

Figure 3 Photographs of three adult male Iguana insularis insularis on the Tobago Cays (Grenadine Islands). A IGU105 (Baradal). This male has the typical coloration of I. insularis insularis with faint black banding, eye with visible white area, nasal horns, small subtympanic plate and very few and small tubercles on the neck, but also presents atypical sublabial scales and conical scales on the nape B IGU112 (Petit Rameau) is a typical older male I. insularis insularis, with no black bands on the body (not shown in this photograph) C IGU110 (Petit Bateau) has a body with small and narrow ventral black bands and numerous black scales on the body. 1. relatively small subtympanic plate 2. mosaic of small scales 3. very low to low number of small neck tubercles 4. lateral and median horns 5. white visible in the eye. 6. brown eye 7. light cream coloration in old adults; green in juveniles and younger adults 8. light dewlap with some black scales (C) 9. small number of small gular spikes (not always visible on the photographs) 10. light body with different degrees of persistence of black stripes 11. light and high dorsal spikes with a pink or orange hue.

Figure 2 Distribution of iguanas in the Grenadine Islands (modified from Henderson and Powell 2018; Breuil et al. 2019). Note there are alien iguanas on some islands and not all of the island clusters shown here have purebred populations of I. insularis insularis. The grey line south of St. Vincent marks the break between the Saint Vincent Bank to the north and the Grenada Bank to the south. The black line between Petit St. Vincent and Petit(e) Martinique shows the political boundary between St. Vincent and the Grenadines to the north and Grenada to the south. The Grenadine Islands form an archipelago from the south of St. Vincent to the north of Grenada. Almost all the Grenadine Islands in St. Vincent and the Grenadines were surveyed during this work and, with the exception of Savan Island, had iguanas at the time of our visits. Petit Mustique was inaccessible during our survey. The islets of Sugar Loaf, Green Island,c and Sandy Island (all in Grenada) are reported to no longer have iguanas (Henderson and Powell 2018) but iguanas fitting the morphology of I. insularis insularis have been observed on Carriacou and Mabouya Islands (see text).

Figure 1 A distribution of the five Iguana species recognized by Breuil et al. (2020). The Lesser Antilles contain three endemic species (I. delicatissima, I. insularis, I. melanoderma) and the invasive aliens I. iguana and I. rhinolopha, which hybridize with the endemic insular taxa. The grey line between Central and South America indicates the approximate limit between the two recognized continental species, but the taxonomy and distribution of iguanas in this area warrants further investigation B the three geological banks referred to in this paper are separated by two horizontal dash black lines. The black line indicates the political boundary between the country of St. Vincent and the Grenadines to the north and Grenada to the south. The iguanas are named according to the results of this study and Breuil et al. (2020).
Hurricane-associated population decrease in a Critically Endangered long-lived reptile
<p><span>Catastrophic events, like hurricanes, bring lethal conditions that can have population-altering effects. The threatened Caribbean dry forest occurs in a region known for its high-intensity hurricane seasons and high species endemism, highlighting the need to better understand hurricane impacts in combination with habitat fragmentation and loss. However, such studies remain rare, and for reptiles are mostly restricted to </span><em>Anolis</em><span>. Here we used single-season occupancy modeling to infer the impact of the intense 2017 Atlantic hurricane season on the critically endangered Lesser Antillean Iguana, </span><em>Iguana delicatissima</em><span>. We surveyed 30 transects across eight habitats on St. Eustatius during 2017–2019, which resulted in 344 individual surveys and 98 iguana observations. Analyses of abundance and site occupancy indicated both measures for 2018 and 2019 were strongly reduced compared to the pre-hurricane 2017 state. Iguanas at higher elevations were affected more profoundly, likely due to higher wind speeds, tree damage and extensive defoliation. Overall, our results indicate a decrease in population estimates (23.3-26.5%) and abundance (22-23.8%) for 2018 and 2019, and a 75% reduction in opportunistic sightings of tagged iguanas between 2017–2018. As only small and isolated </span><em>I</em><span>. </span><em>delicatissima</em><span> populations remain, our study further demonstrates their vulnerability to stochastic events. Considering the frequency and intensity of hurricanes are projected to increase, our results stress the urgent need for population-increasing conservation actions in order to secure the long-term survival of </span><em>I</em><span>. </span><em>delicatissima</em><span> throughout its range. Given the projected increase and poleward shift of hurricanes, our study provides important insights from a non-model species.</span></p>
