Diversity dynamics in New Caledonia: towards the end of the museum model?

<p>Abstract</p> <p>Background</p> <p>The high diversity of New Caledonia has traditionally been seen as a result of its Gondwanan origin, old age and long isolation under stable climatic conditions (the museum model). Under this scenario, we would expect species diversification to follow a constant rate model. Alternatively, if New Caledonia was completely submerged after its breakup from Gondwana, as geological evidence indicates, we would expect species diversification to show a characteristic slowdown over time according to a diversity-dependent model where species accumulation decreases as space is filled.</p> <p>Results</p> <p>We reanalyze available datasets for New Caledonia and reconstruct the phylogenies using standardized methodologies; we use two ultrametrization alternatives; and we take into account phylogenetic uncertainty as well as incomplete taxon sampling when conducting diversification rate constancy tests. Our results indicate that for 8 of the 9 available phylogenies, there is significant evidence for a diversification slowdown. For the youngest group under investigation, the apparent lack of evidence of a significant slowdown could be because we are still observing the early phase of a logistic growth (i.e. the clade may be too young to exhibit a change in diversification rates).</p> <p>Conclusions</p> <p>Our results are consistent with a diversity-dependent model of diversification in New Caledonia. In opposition to the museum model, our results provide additional evidence that original New Caledonian biodiversity was wiped out during the episode of submersion, providing an open and empty space facilitating evolutionary radiations.</p

Integrative taxonomy of the genus Dyscolus (Coleoptera, Carabidae, Platynini) in Ecuadorian Andes

International audienceThe genus Dyscolus Dejean, 1831 is a highly speciose taxon of neotropical Carabidae and the major component of high-altitude ground beetle communities in the tropical Andes. The aim of this study is threefold: (i) refine the taxonomic position of the equatorial members of Dyscolus using molecular data, (ii) provide a delimitation of the species found in Ecuador in páramo and montane forest environments based on a robust combination of molecular and morphological data, (iii) describe the new species and take the nomenclatural decisions made necessary by the results of this study. The seclusion of Dyscolus from more basal platynine clades including Platynus, Batenus and Glyptolenus, is supported by a phylogenetic analysis of the COI marker. Twenty-five new species of Dyscolus, most of them microendemic, are described and illustrated: D. aquator Moret sp. nov. (Tandayapa, Pichincha), D. arauzae Moret sp. nov. (Mt Cayambe, Pichincha), D. arborarius Moret sp. nov. (Parque Nacional Yacuri, Loja), D. barragani Moret sp. nov. (Mt Ayapungu, Chimborazo), D. crespoae Moret sp. nov. (Parque Nacional Podocarpus, Zamora-Chinchipe), D. danglesi Moret sp. nov. (Parque Nacional Yacuri, Loja), D. donosoi Moret sp. nov. (Parque Nacional Podocarpus, Zamora-Chinchipe), D. eleonorae Moret sp. nov. (Cotopaxi and Pichincha provinces), D. famelicus Moret sp. nov. (Papallacta, Napo), D. giselae Moret sp. nov. (Reserva Otonga, Cotopaxi), D. globoculus Moret sp. nov. (Parque Nacional Podocarpus, Zamora-Chinchipe), D. gobbii Moret sp. nov. (Guamaní and Mt Antisana, Pichincha), D. incommunis Moret sp. nov. (Tandayapa, Pichincha), D. marini Moret sp. nov. (Parque Nacional Podocarpus, Loja), D. piscator Moret sp. nov. (Guamaní, Napo), D. placitus Moret sp. nov. (Guamaní, Napo), D. ravidus Moret sp. nov. (Parque Nacional Podocarpus, Loja), D. rivinus Moret sp. nov. (Reserva Otonga, Cotopaxi), D. rugitarsis Moret sp. nov. (Parque Nacional Yacuri, Loja), D. ruizi Moret sp. nov. (Parque Nacional Podocarpus, Loja and Zamora), D. salazarae Moret sp. nov. (Parque Nacional Podocarpus, Loja), D. silvestris Moret sp. nov. (Papallacta, Napo), D. sulcipedis Moret sp. nov. (Parque Nacional Yacuri, Loja), D. verecundior Moret sp. nov. (Mt Illiniza and Mt Corazón, Pichincha) and D. verecundissimus Moret sp. nov. (Mt Chimborazo, Chimborazo). Dyscolus palatus Moret, 1998 is newly synonymized with D. denigratus (Bates, 1891). We demonstrate the subgenus Hydrodyscolus Moret, 1996 to be polyphyletic and therefore consider it a junior synonym of Dyscolus Dejean, 1831

Origine de la biodiversité en Nouvelle-Calédonie (analyse phylogénétique de l'endémisme chez les insectes dictyoptères)

Dans le but d analyser l origine de l endémisme en Nouvelle-Calédonie, l histoire évolutive des Insectes Blattidae (Hexapodes, Dictyoptères) a été reconstruite au niveau moléculaire par l application de différentes méthodes phylogénétiques. Les différents résultats obtenus, aux niveaux régional et local, permettent de modifier fortement les scénarios de l origine de la biodiversité en Nouvelle-Calédonie. Loin d être une relique purement Gondwanienne et une région dont la diversification a été progressive et ancienne ( Modèle Muséum ), la Nouvelle-Calédonie montre les caractéristiques nuancées de toutes les faunes tropicales, avec plusieurs strates de peuplement et une combinaison d événements anciens et récents. Ce scénario se révèle être aussi plus cohérent avec l histoire géologique mouvementée de la Nouvelle-Calédonie, notamment la submersion totale du territoire.PARIS-BIUSJ-Thèses (751052125) / SudocPARIS-BIUSJ-Physique recherche (751052113) / SudocSudocFranceF

Active at the beginning of the night (7.30&ndash;9 pm) on the surface of the leaf litter above ground.&lt;/p&gt; Geographic distribution &lt;p&gt;Only known from the type locality in Southern Ecuador, in the Parque Nacional Podocarpus.

Body length: 10.2 mm (holotype) to 12.3 mm (paratype). Body piceous black, legs brownish with reddish-brown femora. Elytral microsculpture made of oblong sculpticells, shallowly impressed. Head big, convex dorsally; mandibles long and sharp, as long as the length of the head from base to apex of the labium; eyes moderately bulging, genae oblique, slightly convex in dorsal view. Pronotum transverse, subquadrate, narrower at base than at apex; lateroapical lobes broadly rounded; hind angles obtusely rounded; two pairs of lateral setae. Elytra oval-shaped, convex, with effaced humeri. Striae weakly impressed, with traces of punctuation; intervals 1&ndash;4 slightly convex, 5&ndash;8 flat; third interval with five or six discal setae. Last visible abdominal ventrite of the female with two pairs of setae along its apical margin. Legs slender but short; fourth metatarsomere with convex sides, without subapical dorsolateral setae (holotype) or with weak and short subapical dorsolateral setae (paratype), apical lobes ovoid, the outer lobe slightly longer than the inner lobe. Male genitalia: unknown. &lt;i&gt;Female genitalia&lt;/i&gt;: unstudied.&lt;/p&gt; Comparisons &lt;p&gt; This isolated species remotely resembles &lt;i&gt;Dyscolus segnipes&lt;/i&gt; Moret, 1990, with which it coexists in the Guaman&iacute; p&aacute;ramo. &lt;i&gt;Dyscolus segnipes&lt;/i&gt; has much shorter mandibles and well developed subapical dorsolateral setae on the fourth metatarsomere. The COI tree places &lt;i&gt;gobbii&lt;/i&gt; and &lt;i&gt;segnipes&lt;/i&gt; in two clades far apart from each other.&lt;/p&gt; Habitat &lt;p&gt;Humid superp&aacute;ramo, from 4200 to 4400 m a.s.l. The Guaman&iacute; specimen was collected under a stone on the shore of a small lake; the Antisana specimen was collected by pitfall trapping in a mesic environment, 20 metres from a glacier-fed stream.&lt;/p&gt; Geographic distribution &lt;p&gt;Microendemic species, restricted to the Antisana and Guaman&iacute; areas in the Eastern Cordillera.&lt;/p&gt;Published as part of &lt;i&gt;Moret, Pierre &amp; Murienne, Jérôme, 2020, Integrative taxonomy of the genus Dyscolus (Coleoptera, Carabidae, Platynini) in Ecuadorian Andes, pp. 1-55 in European Journal of Taxonomy 646&lt;/i&gt; on pages 40-42, DOI: 10.5852/ejt.2020.646, &lt;a href="http://zenodo.org/record/3829682"&gt;http://zenodo.org/record/3829682&lt;/a&gt
