Movements of scalloped hammerhead sharks (Sphyrna lewini) at Cocos Island, Costa Rica and between oceanic islands in the Eastern Tropical Pacific

Elena Nalesso (2019, [Artículo])

Many species of sharks form aggregations around oceanic islands, yet their levels of residency and their site specificity around these islands may vary. In some cases, the waters around oceanic islands have been designated as marine protected areas, yet the conservation value for threatened shark species will depend greatly on how much time they spend within these protected waters. Eighty-four scalloped hammerhead sharks (Sphyrna lewini Griffith & Smith), were tagged with acoustic transmitters at Cocos Island between 2005–2013. The average residence index, expressed as a proportion of days present in our receiver array at the island over the entire monitoring period, was 0.52±0.31, implying that overall the sharks are strongly associated with the island. Residency was significantly greater at Alcyone, a shallow seamount located 3.6 km offshore from the main island, than at the other sites. Timing of presence at the receiver locations was mostly during daytime hours. Although only a single individual from Cocos was detected on a region-wide array, nine hammerheads tagged at Galapagos and Malpelo travelled to Cocos. The hammerheads tagged at Cocos were more resident than those visiting from elsewhere, suggesting that the Galapagos and Malpelo populations may use Cocos as a navigational waypoint or stopover during seasonal migrations to the coastal Central and South America. Our study demonstrates the importance of oceanic islands for this species, and shows that they may form a network of hotspots in the Eastern Tropical Pacific. © 2019 Nalesso et al.

Following recent mimosoid phylogenetic and phylogenomic studies demonstrating the non-monophyly of the genus Albizia, we present a new molecular phylogeny focused on the neotropical species in the genus, with much denser taxon sampling than previous studies. Our aims were to test the monophyly of the neotropical section Arthrosamanea, resolve species relationships, and gain insights into the evolution of fruit morphology. We perform a Bayesian phylogenetic analysis of sequences of nuclear internal and external transcribed spacer regions and trace the evolution of fruit dehiscence and lomentiform pods. Our results find further support for the non-monophyly of the genus Albizia, and confirm the previously proposed segregation of

Hesperalbizia, Hydrochorea, Balizia and Pseudosamanea. All species that were sampled from section Arthrosamanea form a clade that is sister to a clade composed of Jupunba, Punjuba, Balizia and Hydrochorea. We find that lomentiform fruits are independently derived from indehiscent septate fruits in both Hydrochorea and section Arthrosamanea. Our results show that morphological adaptations to hydrochory, associated with shifts into seasonally flooded habitats, have occurred several times independently in different geographic areas and different lineages within the ingoid clade. This suggests that environmental conditions have likely played a key role in the evolution of fruit types in Albizia and related genera. We resurrect the name Pseudalbizzia to accommodate the species of section Arthrosamanea, except for two species that were not sampled here but have been shown in other studies to be more closely related to other ingoid genera and we restrict the name Albizia s.s. to the species from Africa, Madagascar, Asia, Australia, and the Pacific. Twenty-one new nomenclatural combinations in Pseudalbizzia are proposed, including 16 species and 5 infraspecific varietal names. In addition to the type species Pseudalbizzia berteroana, the genus has 17 species distributed across tropical regions of the Americas, including the Caribbean. Finally, a new infrageneric classification into five sections is proposed and a distribution map of the species of Pseudalbizzia is presented.

Revisiting the phylogeny and taxonomy of the Pithecellobium clade (Leguminosae, Caesalpinioideae) with new generic circumscriptions

Iván Tamayo-Cen Benjamin Torke JOSE ENRIQUE LOPEZ CONTRERAS GERMAN CARNEVALI FERNANDEZ CONCHA Ivón Mercedes Ramírez Morillo Lilia Lorena Can Itza RODRIGO STEFANO DUNO (2022, [Artículo])

We present the most complete molecular phylogeny to date of the Pithecellobium clade of subfamily Caesalpinioideae. This neotropical group was informally recognised (as the Pithecellobium alliance) at the end of the 20th century by Barneby and Grimes (1996) and includes five genera and 33 species distributed from the southern United States and Caribbean Islands to north-eastern South America. Our aims were to further test the monophyly of the group and its genera and to identify sister group relationships within and amongst the genera. A phylogenetic analysis of nuclear ribosomal DNA sequences (ITS and ETS) was performed. The results provide further support for the monophyly of the Pithecellobium clade. The genera Ebenopsis, Pithecellobium and Sphinga were strongly supported as monophyletic. Havardia and Painteria were found to be non-monophyletic, prompting their re-circumscriptions and the description of two new genera: Gretheria and Ricoa. New combinations are made for the three species transferred to the new genera. © Iván Tamayo-Cen et al.

Los seres alados y solares del arte maya en el Norte de Yucatán

Rubén Morante (2023, [Capítulo de libro])

En nuestro trabajo de campo en el norte de Yucatán estudiamos la iconografía de sitios como Chichén Itzá, Ek Balam y Mayapán. En ellos observamos esculturas con gran calidad artística de seres humanos que portan alas y que, por ello, se presentan como seres celestes relacionados con deidades del panteón maya de los periodos Clásico tardío, Clásico terminal y Posclásico temprano. Para esta investigación partimos de un breve contexto etnohistórico, geográfico y arqueológico de otros sitios mayas, del centro y oriente de México, incluyendo imágenes de códices y pinturas que nos hablan del posible significado que las plumas, las alas y las aves tuvieron en Mesoamérica. Procedimos al análisis de las figuras aladas que se presentan en relación con importantes edificios de sitios del norte de Yucatán. La advocación solar que sugieren parece haber sido común y en esta zona, no sólo hablan de los grandes artistas que los esculpieron, sino de un sistema de creencias que pudo emanar de tradiciones mayas muy tempranas, que en el siglo IX d.C. se manifiesta de manera clara mediante un estilo depurado, una maestría técnica y una alta sensibilidad estética.

In our field work in northern Yucatán we studied the iconography of sites such as Chichén Itzá, Ek Balam, and Mayapán. There we saw great artistic quality sculptures of human beings that carry wings, and because of that we think that represented celestial beings related to deities of the Mayan pantheon of Late Classic, Terminal Classic and Early Postclassic periods. In our research we started with reviews of ethnohistorical, geographical and archaeological contexts in other Mayan sites, from central and eastern Mexico, including images from codices and paintings that tell us about the possible meaning of feathers, wings and birds in Mesoamerica. We proceeded analyze winged figures presented in relation to important buildings in northern Yucatán sites. Solar evocation suggested probably was common in this area and, sculptures not only speak about belief systems that could emanate from very early Mayan traditions, but also speak about great artists, that in 9th century AD. clearly manifested it through a refined style, technical mastery and high aesthetic sensitivity.

Perfil epidemiológico y características clínicas de la escleritis en una población del noreste de México

YOLANDA MACIAS RODRIGUEZ (2022, [Artículo])

La epiescleritis (ESC) y escleritis (SC) son enfermedades que se caracterizan por causar inflamación de la capa externa fibrosa del globo ocular, la esclera y epiesclera. Estos padecimientos fueron descritos desde el siglo XIX y el Dr. Watson proporcionó la clasificación clínica que se usa para ordenarlas en sus diferentes subtipos. La etiología de las ESC y SC puede ser idiopática o asociada a causas específicas, como enfermedades autoinmunes, traumatismos, cirugías o infecciones. En diversas poblaciones del mundo se han reportado previamente las características de las ESC y SC. Sin embargo, en la población mexicana solo existen reportes de casos de presentaciones inusuales de ESC y SC y una sola serie reportando las características de la SC. Por lo anterior, se decidió llevar a cabo el presente estudio para expandir el conocimiento acerca de las características de la ESC y SC en la población mexicana. Se realizó un estudio retrospectivo y observacional. El diseño metodológico corresponde a una serie de casos. Se incluyeron pacientes con diagnóstico de ESC y SC, que hubieran firmado el consentimiento informado para participación en investigación clínica. Se analizaron los expedientes físicos y electrónicos de los pacientes que cumplieran con los criterios de inclusión, se tomó la información correspondiente a las variables previamente establecidas y se vació en una hoja de Microsoft Excel y posteriormente se analizaron estadísticamente con el programa SPSS (IBM). Se encontraron y analizaron 55 casos de ESC y 130 casos de SC. En ambos grupos hubo una predominancia del sexo femenino y la edad media fue mayor en pacientes con SC que en ESC (52.26 vs. 44.78 años). El tipo más común de ESC fue la simple y en SC la anterior difusa. La SC posterior fue el subtipo menos frecuente. La etiología más frecuente en ESC y SC fue la idiopática, y la segunda en frecuencia fue la espondiloartropatía asociada al haplotipo HLA B27 y la artritis reumatoide respectivamente. Los motivos de consulta más frecuente fueron ojo rojo solamente y ojo rojo doloroso. Los síntomas más comúnmente descritos por los pacientes con ESC y SC fueron ojo rojo, sensación de cuerpo extraño, dolor, lagrimeo y visión borrosa. Asimismo, los datos clínicos más comúnmente encontrados en pacientes con ESC y SC fueron la ingurgitción de los plexos conjuntivales y epiesclerales, queratopatía punteada superficial y queratitis ulcerativa periférica. La agudeza visual promedio fue buena tanto en ESC como en SC, siendo de 20/25 y 20/30 respectivamente. Para el análisis de tratamiento y recurrencias, se consideraron a los pacientes con un seguimiento mayor a una consulta, consistiendo estos últimos en 35 ESC y 108 SC. En la ESC, 91.4% de los pacientes fueron tratados con un AINE oral, 57.1% con esteroide tópico y 5.7% con AINE tópico. En SC, 76.9% usaron un AINE oral, 62% un esteroide oral, 50% un esteroide tópico y 52.7% un agente imnunosupresor. 29.6% de los pacientes con SC tuvieron una recurrencia. Al comparar la presente serie con las series de ESC y SC reportadas previamente en la literatura se encontró una considerable cantidad de similitudes, como la predominancia del sexo femenino, la media de edad, la incidencia estimada, los síntomas y signos, el tratamiento empleado y la cantidad de recurrencias y su asociación a una edad menor. Debido a todos lo anterior, se concluyó que la presentación de las ESC y SC en la población mexicana es similar a la presentación en otras poblaciones del mundo, previamente reportadas.

Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research—from developing and testing theory on forest structure and dynamics, to estimating forest carbon stocks and their uncertainties, and integrating remote sensing imagery into forest monitoring programmes. However, these data can be surprisingly hard to come by, particularly for certain regions of the world and for specific taxonomic groups, posing a real barrier to progress in these fields. To overcome this challenge, we developed the Tallo database, a collection of 498,838 georeferenced and taxonomically standardized records of individual trees for which stem diameter, height and/or crown radius have been measured. These data were collected at 61,856 globally distributed sites, spanning all major forested and non-forested biomes. The majority of trees in the database are identified to species (88%), and collectively Tallo includes data for 5163 species distributed across 1453 genera and 187 plant families. The database is publicly archived under a CC-BY 4.0 licence and can be access from: https://doi.org/10.5281/zenodo.6637599. To demonstrate its value, here we present three case studies that highlight how the Tallo database can be used to address a range of theoretical and applied questions in ecology—from testing the predictions of metabolic scaling theory, to exploring the limits of tree allometric plasticity along environmental gradients and modelling global variation in maximum attainable tree height. In doing so, we provide a key resource for field ecologists, remote sensing researchers and the modelling community working together to better understand the role that trees play in regulating the terrestrial carbon cycle. © 2022 The Authors.
