Classifying avian drinking behaviour: ecological insights and implications in a changing world
Biological Reviews, EarlyView.ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Communication across territory boundaries: distance-dependent responses in nightingales [PDF]
, 2017 In communication, vocal signals are often used for long-range signaling. Yet, little experimental evidence is available on the role of territorial signals across territory boundaries and their effectiveness at different propagation distances.

The costs of extra‐pair behaviours in birds
Biological Reviews, EarlyView.ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Oikos, EarlyView.By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Vocal ontogeny in neotropical singing mice (Scotinomys). [PDF]
PLoS ONE, 2014 Isolation calls produced by dependent young are a fundamental form of communication. For species in which vocal signals remain important to adult communication, the function and social context of vocal behavior changes dramatically with the onset of ...

Fruit use and fruit processing by euphonias, specialized avian frugivores
Oikos, EarlyView.Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

(Un)markedness of trills : the case of Slavic r-palatalisation [PDF]
, 2010 This paper evaluates trills [r] and their palatalized counterparts [rj] from the point of view of markedness. It is argued that [r]s are unmarked sounds in comparison to [rj]s which follows from the examination of the following parameters: (a) frequency ...

Simulated birdwatchers' playback affects the behavior of two tropical birds. [PDF]
PLoS ONE, 2013 Although recreational birdwatchers may benefit conservation by generating interest in birds, they may also have negative effects. One such potentially negative impact is the widespread use of recorded vocalizations, or "playback," to attract birds of ...

Аbout use of ancient weathering crusts formation during diamond-prospecting works
Мінеральні ресурси України, 2021 Complex research of Late Devonian – Early Carboniferous and Middle-Late Triassic weathering crusts on various rocks (terrigenous-carbonate formations, dolerites, tuffs, tuffaceous formations and kimberlites) indicated that in conditions of warm and humid
