“…We examined three groups of spiders: tarantulas (Theraphosidae), trapdoor spiders (Idiopidae) and wolf spiders (Lycosidae). For an arachnid, tarantulas have an unusually long lifespan, living for up to 34 years and taking up to 6 years to reach sexual maturity (Ibler et al, 2013; Kotzman, 1990; Mason et al, 2018; Montes de Oca & Mendoza, 2020). Males have a shorter lifespan and reach maturity earlier than females.…”

“…Males have a shorter lifespan and reach maturity earlier than females. At maturity, males leave their burrow in search of mates and generally die within months (Montes de Oca & Mendoza, 2020). The Australian tarantula Selenocosmia stirlingi , found within the study area, has a gestation period of about 9 months, followed by a parental care period of roughly 4 months (Kotzman, 1990).…”

The density and abundance of arid‐dwelling taxa often change significantly in response to precipitation fluctuations and the abundance of their predators. The survival and density of burrowing arthropods and their burrows in arid environments following prolonged dry periods and subsequent rains is poorly understood, as is the potential influence of reintroductions of their predators, such as fossorial mammals. The persistence of these arthropods and their burrows may be important for other species that rely on them for food or use their burrows for shelter. In this study, we examined the density of burrowing and ground‐nesting arthropods and their burrows in Australia's Strzelecki Desert over two years between 2019 and 2021. This period spanned the tail‐end of the worst drought on record and subsequent drought‐breaking rains. We employed a Before‐After Control‐Impact (BACI) study design to examine the short‐term effects of a fossorial mammal reintroduction of the greater bilby (Macrotis lagotis) into predator‐free fenced exclosures and used an inspection camera to detect the presence of spiders and other taxa within individually marked burrows. We observed the largest changes in arthropod abundance and burrow density between a period that encompassed a third consecutive summer in drought and the commencement of drought‐breaking rains, with some taxa declining by as much as 77% (p < 0.001). While the density of harvester ant middens erupted over this time, the density of tarantulas, trapdoor spiders and scorpions declined significantly. The greater bilby reintroduction had no short‐term effect on the densities of the arthropods or their burrows, but their arrival may have implications on their post‐drought recovery. Further studies are needed to determine if the significant declines in arthropod populations and burrows are reflective of normal boom‐bust population dynamics due to the poor natural history knowledge of the arthropods we examined.

“…Actualmente no hay suficientes sistemas de caracterización de los estudiantes que consideren variables de índole afectiva, cognitiva o social, relacionadas con preferencias por un programa universitario de pregrado, por lo que no existe un sustento empírico que guíe a las instituciones en programas de apoyo a estos procesos (Carrasco-Salazar et al, 2014). En la misma línea, las falencias del proceso formativo, en cuanto a la correcta inserción de la orientación vocacional en el currículum, serían un aspecto que impide al estudiante realizar la selección adecuada del programa universitario que quiere cursar, pues, en el orden institucional, se deses-tima la importancia de su autoconocimiento, así como las propias limitaciones, las fortalezas y las preferencias (Mendoza et al, 2016).…”

Para los jóvenes, la elección acertada de un pro-grama universitario constituye un desafío para ellos, su familia y la sociedad, puesto que el desarrollo personal, el éxito profesional, los valores y el servicio a la comunidad dependen de ella. Considerando que los factores que intervienen en esta elección son variados, el estudio buscó determinar, empíricamente, si el grado de autoestima y moti-vación escolar tiene efecto en la matrícula de un programa universitario, como primera preferencia. La muestra corresponde a los 2626 jóvenes que ingresaron a la Universidad de Concepción, Cam-pus Chillán, en 2016-2021. Se utilizó un modelo pro-bit binario, pues la variable dependiente toma uno de dos valores discretos. El grado de autoestima y motivación se midió a partir de uno de los índices de desarrollo personal y social (IDPS), entregado por la Agencia de Calidad del Ministerio de Educación de Chile para cada establecimiento de egreso de enseñanza media. Se incorporaron variables de control, como las características personales del estudiante y del establecimiento. Los resultados conﬁrman que, cuanto mayor es el índice de autoestima y moti-vación escolar, mayor es la probabilidad de que el estudiante ingrese al programa de su primera preferencia. Este análisis conﬁrma (1) la importancia de este Indicador y (2) que aún faltan avances para fortalecer programas escolares que pongan el énfasis en propiciar condiciones que permitan el desarrollo integral de los estudiantes, destacando las fortalezas por sobre las debilidades.

Searching the web builds fuller picture of arachnid trade

et al. 2022

Wildlife trade is a major driver of biodiversity loss, yet whilst the impacts of trade in some species are relatively well-known, some taxa, such as many invertebrates are often overlooked. Here we explore global patterns of trade in the arachnids, and detected 1,264 species from 66 families and 371 genera in trade. Trade in these groups exceeds millions of individuals, with 67% coming directly from the wild, and up to 99% of individuals in some genera. For popular taxa, such as tarantulas up to 50% are in trade, including 25% of species described since 2000. CITES only covers 30 (2%) of the species potentially traded. We mapped the percentage and number of species native to each country in trade. To enable sustainable trade, better data on species distributions and better conservation status assessments are needed. The disparity between trade data sources highlights the need to expand monitoring if impacts on wild populations are to be accurately gauged and the impacts of trade minimised.
