Isotopic niche overlap between the invasive leiothrix and potential native competitors

We analysed niche overlap between the red–billed leiothrix Leiothrix lutea, a spreading exotic invasive bird, and the European robin Erithacus rubecula and the blackcap Sylvia atricapilla, similar native species, which are commonly considered as potential competitors in Mediterranean forests. We analyzed stable isotope ratios (δ13C and δ15N) from feathers of birds sampled in several locations within the Collserola mountain range (Barcelona, NE Spain) where leiothrix have strongly increased their numbers in the last decade and quantified niche overlap with nicheROVER. Blackcap individuals showed the lowest probability to be found in the isotopic niche of the other two species (around 60 %), while leiothrix and robins showed a high probability to share the same isotopic niche (82 %). Our results stress that competition for resources is potentially high and the species shared marked niche asymmetries, which may have implications for community dynamics in the long term

El programa Biodiversitat Micològica de les terres de Ponent. Notícia i primers resultats.

La tardor de 1994 ha presentat unes condicions molt favorables de pluviositat, humitat i temperatura, que han permès un estudi intensiu (59 excursions, 64 localitats) de la part occidental, baixa i seca, de Catalunya, de la qual es tenien molt poques dades micològiques. E1 catàleg preliminar que oferim, amb tot i l'absència de moltes espècies pendents d'estudi o confirmació, i també de les més eurioiques, considerades poc característiques, conté 170 espècies, i permet fer-se una idea de la flora fúngica xero-termòfila mediterrània, especialment, la de les brolles, pinedes i espais oberts. Al costat d'algunes espècies poc citades, com Eutryblidiella hysterina, Helvella villosa, Agaricus pilatianus, Amanita boudieri, Calyptella capula, Ceriporia bresadolae, Coprinus vosoustii, Henningsomyces puber, Hygrophorus carneogriseus, Marasmius corbariensis, Phellinus punctatus, Ramicola iberica, Skeletocutis percandida, Tulostoma nanum, T. occidentale, T. xerophilum, Typhula setipes, Xerocomus ichnusanus, d'altres han mostrat una abundància inusitada, com Mycocalicium minutellum, Amanita ovoidea, Clitocybe alexandrí, C. umbilicata, Entoloma rusticoides, Hebeloma edurum, Inocybe roseipes, Lepista rickenii, Lopharia spadicea, Omphalotus olearius, Phaeotellus rickenii, Polyporus meridionalis, Suillus bellinii, S. collinitus, Volvariella speciosa, Mucilago crustacea.

First look at soundscape biodiversity in tropical rainforests of the North Malaya Peninsula (Malaysia)

During September 2016, a recording expedition was undertaken in the Peninsular Malaysian rainforest, one of the most biodiverse areas on the planet. Semi-continuous recordings (one minute recording every five minutes) were obtained using Wildlife Acoustics SM4 recorders in order to characterize soundscape biodiversity and its relation to anthrophony using the Bioacoustic Diversity (BIO) and Normalized Difference Soundscape (NDSI) indices from the soundecology package for the R statistical computing environment. The recorders were located both within the interior of Belum National Park as well as in well preserved forests on its periphery. The relationship between biophony and anthrophony was obtained at sites known as kampungs orang asli, villages belonging to aborigines of the Temiar and Jahai ethnic communities located beside the forest. These results are compared with the values of acoustic indices obtained using similar methods in Mediterranean woodlands within the Collserola Natural Park (Barcelona), Spain. The recordings obtained in Peninsular Malaysia using both the SM4 and a Zoom H4n recorder combined with an Audio-technica handheld microphone have also allowed for testing of automated detection of specific rainforest species. During this initial testing phase, we chose the great argus (Argusianus argus), a phasianid bird known locally as the Burung Kuan for automatic detection using the monitor R package for acoustic template detection using R
