Re-establishment of the genus Pseudalbizzia (Leguminosae, Caesalpinioideae, mimosoid clade): the New World species formerly placed in Albizia

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.

Trichoderma: recurso microbiológico y sus aplicaciones en la agricultura en Yucatán, México

Los productos sintéticos como nematicidas, fungicidas y fertilizantes empleados en la producción agrícola, contaminan suelo, agua y ocasionan daño a la salud de los productores y consumidores. Una alternativa al uso de estos agroquímicos son los microorganismos que habitan en el suelo, como los hongos del género Trichoderma, que promueven el crecimiento de cultivos y controlan enfermedades de plantas que se originan en la raíz, lo que favorece el cultivo agrícola libre de agroquímicos sintéticos. En esta nota se dan a conocer los modos de acción de Trichoderma y los avances de estudios realizados con cepas nativas del estado de Yucatán, para el control de patógenos en solanáceas.

Efficiency of combating property violence in the Northwest region of Mexico

Martin Flegl Eva Selene Hernández Gress (2023, [Artículo, Artículo])

The situation of violence in Mexico shows an alarming trend as the number of committed crimes increased by 10.9% in 2021 compared to 2020. In fact, 75.6% of the Mexican population perceives the insecurity. Due to the above, it is necessary to strengthen public security to combat this trend. However, the resources allocated to the public security in Mexico are limited. Although there are studies that investigate what causes the violence in Mexico, so far there is no study that measures the efficiency of combating the violence related to budgetary, human, and material resources of the public security. This article investigates the efficiency of combating the property violence in 206 municipalities in the Northwest region of Mexico through the Data Envelopment Analysis. The results show a low efficiency (56.67%) with significant differences between the states in the region. Baja California is the state with the lowest efficiency (17.61%), whereas the highest efficiency is found in Durango (67.25%). For the last, the need to carefully plan changes in the police force and the public security infrastructure was noted to improve the efficiency and the level of security.

Data for the synthesis, characterization, and use of xerogels as adsorbents for the removal of fluoride and bromide in aqueous phase

NAHUM ANDRES MEDELLIN CASTILLO ELIZABETH DIANE ISAACS PAEZ Liliana Giraldo Gutiérrez JUAN CARLOS MORENO-PIRAJAN ITZIA RODRIGUEZ MENDEZ SIMON YOBANNY REYES LOPEZ JAIME REYES HERNANDEZ SONIA JUDITH SEGOVIA SANDOVAL (2022, [Artículo])

"Groundwater with high fluoride concentrations has been recognized as one of the serious concerns worldwide. Besides, the fluoride released into the groundwater by slow dissolution of fluoride-containing rocks, various industries also contribute to fluoride pollution [1]. Excess intake of fluoride leads to various health problems such as dental and skeletal fluorosis, cancer, infertility, brain damage, thyroid diseases, etc. [2]. On the other hand, bromide is naturally present in surface and groundwater sources. However, during the chlorination process, bromide can be oxidized to HOBr, which can react with natural organic matter in water to form brominated organic disinfection byproducts, which are very harmful to human health [3]. Among various methods for water treatment, the adsorption process has been widely used and seems to be an efficient and attractive method for the removal of many contaminants in water, such as anions, in terms of cost, simplicity of design, and operation [4,5]. In the past years, xerogels and carbon xerogels, a new type of adsorbents, which are synthesized by the sol-gel polycondensation of resorcinol and formaldehyde, have gained attention due to their moldable texture and chemical properties [6]. Moreover, melamine addition in resorcinol and formaldehyde xerogels adds basic groups on its surface, favouring Lewis acid-base interactions between xerogels and other components by adsorption [7]. In this data article, the synthesis of three resorcinolformaldehyde (R/F) xerogels with an increasing amount of melamine (M) was carried out by colloidal polymerization (molar ratios of M/R = 0.5, M/R = 1.0, and M/R = 2.0). Additionally, samples of M/R = 0.5 xerogel were carbonized at 400, 450, and 550 degrees C under an inert atmosphere to increase their specific area. Organic and carbon xerogels obtained were characterized by FTIR, TGA, SEM, Physisorption of N 2, and the pH at the point of zero charge (pH PZC). All organic xerogels were also tested as adsorbents on the removal of fluoride and bromide ions from aqueous phase. The Freundlich, Langmuir, and Radke-Prausnitz isotherm models were applied to interpret the experimental data from adsorption equilibrium. Additionally, the data of the mass of the xerogel needed to remove fluoride and bromide from groundwater and fulfill the maximum concentration levels are also included."
