Abstract The biodiversity of tropical rainforests is under extreme pressure due to the expansion agricultural land. Beyond immediate risk species extinction, intensification land use can alter species' behaviour with consequences for entire ecosystem. In this study we investigated impact on acoustic cicadas in highly biodiverse Ecuadorian Chocó region. We used passive monitoring (PAM) collection audio data, from which identified and analysed sound activity structure daily patterns along a chronosequence forest recovery. At landscape scale studied surrounding either dominated by or forests cicadas. Cicada was significantly lower active agriculture compared undisturbed old‐growth increased recovery gradient. diurnal pattern changed simple more complex synchronized gradient towards forests. A additionally reduced simplified Taken together, at local scales affects overall activity, synchrony vocalizing song This concerning trend considering direct link between chorusing fitness However, mature restoration embedded surroundings showed restored cicada behaviours similar those forests, underlines conservation value advanced secondary importance support regeneration tropics.

Swallows (Hirundo spp.) inhabit a variety of habitats in both tropical and temperate zones. Barn rustica), particular, frequently roost large numbers construct mud nests on buildings, causing nuisance to humans. At the Glami Lemi Biotechnology Research Centre (GLBRC), which is located Peninsular Malaysia, there are certain structures that utilised by number swallows for perching resting. This results defacement exterior walls caused their droppings. Hence, analysis presented this paper delves into factors influencing presence numbers. The objective study was examine fluctuations perched relationship with three environmental parameters: temperature, relative humidity, light intensity. Three hours observation were conducted two different sessions (i.e., morning afternoon) times per week one year. showed appeared be stable throughout year, except November December, when it increased tremendously reached its peak.
