Latitudinal diversity gradients (LDG) and their explanatory factors are among the most challenging topics in macroecology and biogeography. Despite of its apparent generality, a growing body of evidence shows that ‘anomalous’ LDG (i.e., inverse or hump-shaped trends) are common among marine organisms along the Southeastern Pacific (SEP) coast. Here...
Environmental shifts are projected to lead to expansions, contractions and shifts in the geographic range of species in response to climate change. Most distribution forecasting methods assume that species respond to the environment as an undifferentiated entity along their entire distribution. However, environmental heterogeneity along a species’...
Este manual lo escribí con el afán de aportar en algo a la labor que ejercen los grupos de voluntarios, luego de participar por muchos años en ellos. Si es de ayuda para al menos una persona, ya me doy por pagado.
En este manual identifico los principales hitos de la ejecución de un voluntariado, y sugiero distintas formas de abordar sus problemas...
Despite its theoretical relationship, the effect of body size on the performance of species distribution models (SDM) has only been assessed in a few studies, and to date, the evidence shows unclear results. In this context, Chilean fishes provide an ideal case to evaluate this relationship due to their short size (fishes between 5 cm and 40 cm) an...
Simple Nicho es un software desarrollado por el proyecto FIA PYT-2016-0203, cuyo objetivo es el modelado de nichos ecológicos de especies exóticas para determinar su potencial distribución espacial sobre territorio chileno. Este software consiste en una interfaz gráfica desarrollada en R v 3.5.0 (R Core Team, 2017) por medio del paquete Shiny (http...
Didymosphenia geminata is a diatom that can alter aquatic systems. Several investigations have shown as chemical, and hydraulic factors have a great influence on the proliferation of D. geminata , but the study of other microalgae that could be associated with it has been poorly addressed. The objective of this study is to evaluate the relationship...

Despite its theoretical relationship, the effect of body size on the performance of species distribution models (SDM) has only been assessed in a few studies of terrestrial taxa. We aim to assess the effect of body size on the performance of SDM in river fish. We study seven Chilean freshwater fish, using models trained with three different sets of...

Background: Seed mass is a life history trait that is related to invasiveness. Under limiting conditions, a trade-off is observed whereby an increase in seed mass occurs at the expense of seed numbers; if the above trade-off holds across climatic gradients it can provide an opportunity to assess the fitness/invasive potential of exotic plants.
Aims...
A national-scale study of outcrossing potential within Chilean vascular flora was conducted using an upgraded algorithm, which adds parameters such as pollinator agents, climate, and geographic conditions. Datasets were organized and linked in a Web platform (www.flujogenico.cl), in which the development of a total outcrossing potential (TOP) predi...
Ha sido demostrado como la presencia de actividades antrópicas en hábitats fluviales determinan la disminución local de sus poblaciones. Al mismo tiempo, gran parte de estas especies en Chile se encuentran en alguna categoría de conservación, demostrando la gran presión antrópica ejercida sobre estos ecosistemas. Modelar la distribución geográfica...

RESUMEN
El peso de semilla es un atributo de historia de vida heredable que impacta significativamente sobre la adecuación biológica de las plantas. Su aumento ocurriría en desmedro del número de semilla; de esta forma, los individuos se ven sometidos a un compromiso entre el peso y el número de semillas, y su optimización se encuentra sometida a s...
Didymosphenia geminata (Lyngbye) Schmidt es una diatomea unicelular bentónica, endémica del Hemisferio Norte. Debido a su gran capacidad invasiva, produce proliferaciones masivas conocidas como “Didymo” o “Moco de Roca”, las que han llegado a cubrir un 100% de los sustratos en kilómetros de río, produciendo alteraciones fisicoquímicas y numerosos p...
El Mapa Chileno de la Extinción de Especies (www.proyectobiota.cl), es un modelo espacial ponderado montado en una plataforma Webmapping generada con tecnologías Open Source (código libre). Éste mapa representa de manera gráfica, lúdica e interactiva, las áreas del país en donde es posible encontrar mayor concentración de especies en categoría de c...
Didymosphenia geminata es una diatomea unicelular bentónica, reconocida como especie invasora a nivel mundial. La plaga se desarrolla en ríos oligotróficos y se caracteriza por la producción de grandes cantidades de mucílago, que generan alteraciones fisicoquímicas y numerosos problemas ambientales. En Chile se registró un crecimiento masivo a comi...
Modelos de análisis de viabilidad poblacional (PVA), logran identificar los riesgos de extinción en las poblaciones y han jugado un rol fundamental en Biología de la Conservación para identificar especies vulnerables o en peligro. Una mirada alternativa podría servir para evaluar la invasibilidad de las especies exóticas. Así, especies con menor ri...
