“…Through the collection and identification of bycatch, it is possible to incidentally monitor the communities of beneficial arthropods present in the system. Bycatch data can be collected in monitoring programmes with extensive spatial and temporal coverage and hold valuable potential for application in conservation studies (Wieten et al 2012; Hung et al 2015; Mester et al 2020; Petsopoulos et al 2021). Despite the tremendous potential, bycatch data are often ignored and excluded from analyses and publications because of the additional work required to sort and identify specimens of perceived secondary value than the target pest (Petsopoulos et al 2021).…”

The invasive pea leaf weevil, Sitona lineatus (Linnaeus) (Coleoptera: Curculionidae), damages field peas, Pisum sativum Linnaeus (Fabaceae), and faba beans, Vicia faba Linnaeus (Fabaceae), on the Canadian prairies. We used semiochemical-baited pitfall traps to monitor and detect S. lineatus range expansion and capture associated predaceous ground beetles (Coleoptera: Carabidae) in pulse-growing regions across Alberta. Traps captured male and female S. lineatus in all pulse-growing regions in the spring and fall, including a first record of S. lineatus in the Peace River region of northwestern Alberta. Pheromone-baited traps captured more weevils than unbaited traps did, and the addition of host plant volatiles did not increase the catch. More weevils were captured in traps in pea fields compared to in faba bean fields. Rubber septa lures released more pheromones and attracted a similar number or more weevils to traps than microcentrifuge tube lures did. Ground beetle capture was not affected by semiochemical baits targeting S. lineatus. Ground beetle diversity varied by region and collection period, but the most frequently collected species was Pterostichus melanarius, a potential predator of S. lineatus. This study shows that pitfall traps baited with rubber septa pheromone lures can be used to monitor new and expanding S. lineatus populations, as well as potential natural enemy communities.

“…Sin embargo, en el área de amortiguamiento del área protegida existieron varias zonas de pastizales; no obstante, solamente en un pequeño pastizal se registró un cuerpo de agua, el cual favoreció la presencia de las ranas. Según Garey & Provete (2016) y Mester et al (2020), las zonas de amortiguamiento se están convirtiendo en refugios para los anfibios, ya que proporcionan hábitats que garantizan el mantenimiento y la conectividad de las poblaciones de anfibios con los hábitats idóneos dentro de las áreas protegidas. Jiménez-Casalombo et al-G. riobambae en un gradiente de urbanización a desaparecer dentro del área protegida, causando que se redujeran las poblaciones de G. riobambae.…”

“…Posiblemente la pequeña población de G. riobambae registrada en el área de amortiguamiento del área protegida, se encontraba aislada ya que la distancia de este hábitat hacia otro similar dentro del área protegida es muy extensa. Mester et al (2020) en su estudio con varias especies de anfibios en el Parque Nacional Hortobágy, menciona que, para evitar poblaciones aisladas se debe trabajar en restaurar la conexión de hábitats en zonas de amortiguamiento de áreas protegidas, para así ampliar hábitats idóneos y establecer una conectividad funcional con las áreas protegidas. Sin embargo, el cuadrante establecido para la zona conservada no abarcó toda el área protegida, solamente se realizó un muestreo en el sendero principal, paralelo al canal de agua Valdés hasta llegar al río Sambache y sus alrededores.…”

Las ranas marsupiales han atravesado dramáticas declinaciones poblacionales en Ecuador, como consecuencia de la transformación y pérdida de hábitats naturales, entre otras causas. Este estudio busca entender cómo varía la abundancia de Gastrotheca riobambae en un gradiente de urbanización, que incluye zonas conservadas, rurales, periurbanas y urbanas en la provincia de Pichincha, Ecuador. Cada zona se demarcó por un cuadrante de 100 hectáreas, en donde se caracterizaron diecisiete variables de composición de paisaje y hábitat de reproducción, se realizaron tres transectos de 500 x 3 m para el registro de ranas adultas, además de barridos con redes de acuario para registrar la abundancia de renacuajos en los cuerpos de agua. Se realizó un análisis de componentes principales (ACP) para evaluar la correlación entre variables de composición de paisaje y hábitat de reproducción, después se ajustó un Modelo Aditivo Generalizado (GAM) para relacionar la abundancia con las variables no correlacionadas. Se registraron 94 ranas adultas y 312 renacuajos en el gradiente de urbanización, el cual influyó de manera significativa en la variación de la abundancia de G. riobambae (X2(2) = 20.63, p < 0.001; X2(2) = 66.98, p < 0.001). Sin embargo, y al contrario de lo esperado, no se presentó una relación lineal en el gradiente de urbanización, ya que las zonas rural y peri-urbana, presentaron una mayor abundancia de ranas que la zona conservada. La cantidad de cuerpos de agua, las áreas de pastizales y la cobertura vegetal estuvieron relacionadas con las zonas de mayor abundancia a lo largo del gradiente, al igual que la cobertura de dosel, la temperatura superficial y el volumen del cuerpo de agua, los cuales describen el hábitat de reproducción. Se concluye que, G. riobambae ocupa ambientes transformados por actividades humanas en zonas rurales y periurbanas, pero estos hábitats requieren ciertas características idóneas para su desarrollo y supervivencia.

“…Postrestoration succession can often lead to states when the number of species and/or conservation values first increases and then it declines (e.g. Mester et al 2020). For example, flower-rich temperate montane hay meadows, which depend on regular low-intensity use by mowing or grazing, undergo succession upon abandonment of use, leading to shrub encroachment and eventually to a closed forest (Prokopová et al 2018).…”

Ecosystem restoration implies focusing on multiple trophic levels and ecosystem functioning, yet higher trophic levels, that is, animals, are less frequently targeted by restoration than plants. Habitat diversity, the spatial heterogeneity between and within habitat patches in a landscape, is a well-known driver of species diversity, and offers possible ways to increase species diversity at multiple trophic levels. We argue that habitat diversity is central in whole-ecosystem restoration as we review its importance, provide a practical definition for its components, and propose ways to target it in restoration. Restoration targeting habitat diversity is used commonly in aquatic ecosystems, mostly to increase the physical diversity of habitats, meant to provide more niches available to a higher number of animal species. To facilitate the uptake of habitat diversity in terrestrial ecosystem restoration, we distinguish between compositional and structural habitat diversity, because different animal groups will respond to different aspects of habitat diversity. We also propose four methods to increase habitat diversity: varying the starting conditions to obtain divergent successional pathways, emulating natural disturbances, establishing keystone structures, and applying ecosystem engineer species. We provide two case studies to illustrate how these components and methods can be incorporated in restoration. We conclude that targeting habitat diversity is a promising way to restore habitats for a multitude of species of animals and plants, and that it should become mainstream in restoration ecology and practice. We encourage the restoration community to consider compositional and structural habitat diversity and to specifically target habitat diversity in ecosystem restoration.
