“…Aun así, fue posible agregar 17 sitios en 7 años, en circunstancias que Martin (2011), compiló un total de solo 21 localidades para el período 1924-2011. Es probable que con diseños de muestreos pertinentes para la especie -ubicación de cámaras dirigida a micromamíferos, en sectores húmedos, con porciones de suelo descubierto y alta cobertura de sotobosque (Martin 2011)-sea posible incrementar de forma significativa el número de registros y el conocimiento de la comadrejita trompuda de forma similar a lo que ha ocurrido con otras especies como el monito del monte (Fontúrbel y Jiménez 2009, Oda et al 2019, Godoy-Guinao et al 2023.…”

In this work, we report new records of the Chilean shrew opossum (Rhyncholestes raphanurus), one of the least known mammals of the South American temperate rainforests. Using camera traps, we detected Chilean shrew opossums on 31 different occasions distributed over 17 sites, located in two protected areas of the Los Ríos region, southern Chile. The records, obtained in evergreen and alerce forests, as well as in eucalyptus plantations, show markedly nocturnal activity. These findings represent a significant increase in the number of locations where the presence of this species has been confirmed.

“…Forest ecosystems are three‐dimensional, with different characteristics influencing bird species' habitat use (Thiollay, 1992 ). A recent study using camera traps to assess species habitat use showed bird species‐specific vertical stratification patterns in temperate forests (Godoy‐Güinao et al, 2023 ). Among others, bird habitat selection in forest systems is influenced by the structural features of forests like deadwood, canopy cover, canopy openness (Bradfer‐Lawrence et al, 2020 ) and vertical foliage cover (grass, shrub, herbaceous, tree) and height (Gumede, Ehlers Smith, Ngcobo, et al, 2022 ; Maseko et al, 2019 ).…”

“…We predicted that increased structural complexity would increase bird species richness and functional diversity. Forest specialist bird species have specific microhabitat requirements (Murphy et al, 2018 ) with a strong vertical stratification in habitat use (Godoy‐Güinao et al, 2023 ). Also, the selected focal forest specialist species differ in their forest strata habitat use.…”

Forest transformation has major impacts on biodiversity and ecosystem functioning. Identifying the influence of forest habitat structure and composition on avian functional communities is important for conserving and managing forest systems. This study investigated the effect of forest structure and composition characteristics on bird species community structure, habitat use and functional diversity in 14 Mistbelt Forest patches of the Midlands of KwaZulu‐Natal in South Africa. We surveyed bird communities using point counts. We quantified bird functional diversity for each forest patch using three diversity indices: functional richness, functional evenness and functional divergence. We further assessed species‐specific responses by focussing on three avian forest specialists, orange ground‐thrush Geokichla gurneyi, forest canary Crithagra scotops and Cape parrot Poicephalus robustus. We found that bird community and forest‐specialist species responses to forest structure and tree species diversity differed. Also, forest structural complexity, canopy cover and tree species richness were the main forest characteristics better at explaining microhabitat influence on bird functional diversity. Forest patches with relatively high structural complexity and tree species richness had higher functional richness. Different structural characteristics influenced habitat use by the three forest specialists. Tree species diversity influenced C. scotops and G. gurneyi positively, while P. robustus responded negatively to forest patches with high tree species richness. Our study showed that site‐scale forest structure and composition characteristics are important for bird species richness and functional richness. Forest patches with high tree species diversity and structural complexity should be maintained to conserve forest specialists, bird species richness and functional richness.
