“…Previous studies have shown that changes in land‐use affect species richness (Palacio et al., 2020), with forest bird populations, and hence species richness generally increasing, while they decrease in agricultural and scrubland environments (Cabodevilla et al., 2022; López Bermúdez et al., 2016). In this line, forest expansion due to agricultural abandonment (Lasanta‐Martínez et al., 2005) may be beneficial for forest specialist species (Reino et al., 2018) by providing food resources and structural cover, although species richness may also be influenced by species functional traits (Lisón et al., 2022).…”

AimWhen studying the effects of global change on biodiversity, it is far more common for the effects of climate change and land‐use changes to be assessed separately rather than jointly. However, the effects of land‐use changes in recent decades on species richness in areas affected by climate change have been less studied. We assess the temporal turnover in species richness of an avian community between a historical period and a modern one as a consequence of global change.LocationSemiarid Mediterranean ecosystem (southeastern Spain).MethodWe fitted a hierarchical multispecies occupancy model for each period (1991–1992, and 2012–2017), obtaining avian species‐specific estimates of occupancy probability in relation to environmental covariates (elevation and forest cover). We analyse the relationships between changes in the bird community and environmental variables, analysing the temporal turnover of the species richness and the richness‐based species‐exchange ratio.ResultsThe estimated species richness accounting for detectability was higher than observed species richness, and decreased in the more recent period. Following our hypotheses, we observed a dual pattern of species richness increase associated with different elevations, showing different species turnover rates due to the joint effects of climate change and land‐use change. There is a trend towards greater species richness with higher elevations that is associated with climate change, where the species turnover rate is low. Also, species richness increased towards lower elevations, but with a high turnover rate. The latter can be due to species expansions throughout new habitat configurations in bordering forest systems associated with anthropic land‐use changes.ConclusionsOur study is of great interest to understand the temporal turnover of avian species richness associated with areas experiencing both climate and land‐use change.

“…Aunque la zona centro-sur de Chile ha sido reconocida como un punto caliente global de biodiversidad (Fuentes-Castillo et al, 2020;Myers et al, 2000), en las últimas décadas el valle central ha sufrido importantes transformaciones antrópicas con gran pérdida de bosque nativo, que se han transformado en pastizales para ganado, cultivos y plantaciones forestales de especies exóticas como Pinus spp. y Eucalyptus globulus (Lisón et al, 2022;Miranda et al, 2015Miranda et al, , 2017. Sin embargo, esta transformación no ha sido homogénea en todo el territorio y se han generado dos tipos de paisajes: (1) paisajes heterogéneos con pequeñas manchas de cultivos e interconectados por una red de áreas forestales y (2) paisajes homogéneos con grandes manchas de cultivos y manchas de bosque poco conectadas (ver Figura 1; Datos S1).…”

ResumenA pesar de su importancia ecológica y económica, en Chile se desconocen muchos aspectos de la ecología de los murciélagos y de su distribución. Esta situación no permite una correcta implementación de los esfuerzos de conservación aún cuando son legalmente reconocidos por sus beneficios para la agricultura. En este trabajo estudiamos la actividad y la comunidad de murciélagos en dos tipos de paisaje agrícola (homogéneo vs. heterogéneo) en un hotspot de biodiversidad en el centro‐sur de Chile. Para ello, monitoreamos cuatro transectos de 10 km en cada tipo de paisaje, con 10 puntos de escucha separados por 1 km. Estos transectos se repitieron 5 veces, una vez al mes. Evaluamos la actividad de los murciélagos según el tipo de cobertura forestal (nativa, mixta y plantaciones) y la densidad de árboles aislados. Nuestros resultados mostraron que el paisaje heterogéneo fue dominado por Tadarida brasiliensis mientras que el paisaje homogéneo fue dominado por Lasiurus spp. Sin embargo, sólo la especie T. brasiliensis fue afectada por el tipo de paisaje. En el paisaje heterogéneo, sólo las variables de cobertura forestal tuvieron un impacto significativo en la actividad de las especies de murciélagos, donde Lasiurus spp. y Myotis chiloensis tuvieron una respuesta positiva para bosque nativo y mixto, así como Lasiurus spp. tuvo una respuesta negativa para plantaciones. La densidad de árboles aislados tuvo un efecto negativo sobre la actividad de T. brasiliensis y Lasiurus spp. en el tipo de paisaje homogéneo. Nuestros resultados muestran la importancia de considerar los elementos forestales en el paisaje agroforestal para conservar las comunidades de murciélagos.

“…The impact of landscape context on species has been examined with birds in many regions [ 10 ], with examples including forests [ 11 ] and farmland [ 12 ]. Different responses of forest birds to different forest conditions have been observed in forest landscapes [ 13 , 14 , 15 ].…”

Landscape context can reflect the habitat structure and play an important role in bird species occurrences and abundance. For local biodiversity conservation and restoration, we examined the effects of landscape context on bird communities at different altitude gradients. Our study was conducted in four altitude gradients (<300 m, 300–599 m, 600–899 m, 900–1200 m) of subtropical evergreen broad-leaved forest in Wuyishan National Park, China. The bird survey was carried out in 115 transects in spring, summer, autumn and winter. We examined the effects of altitude, season and landscape context. The result showed that (1) species richness and abundance at <300 m altitude were highest among the four altitude gradients, and they showed more significant differences than those at other altitude gradients; (2) the species richness of birds was associated with altitude, season and landscape context, as the season is more significant than other explanatory variables; (3) at the landscape level, habitat configuration is more important. The average canopy height and contagion index positively correlated with the species richness and abundance of birds at all four altitude gradients. In particular, the average canopy height is significant at 300–599 m and 600–899 m altitude gradients. The study results can provide a theoretical basis and guidance for future national park conservation and management and ecological restoration in the subtropical evergreen broad-leaved forest regions.
