Bird pollination of Canary Island endemic plants [PDF]
, 2008 The Canary Islands are home to a guild of endemic, threatened bird pollinated plants. Previous work has suggested that these plants evolved floral traits as adaptations to pollination by flower specialist sunbirds, but subsequently they appear to be ...

Strong diel variation in the activity of insect taxa sampled by Malaise traps
Ecological Entomology, EarlyView.Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

Ibis, EarlyView.Biodiversity conservation requires effective monitoring of ecological communities in remote locations, where limited accessibility often restricts survey efforts. Passive acoustic monitoring (PAM) is becoming an established method for measuring biodiversity, facilitated by the increased accessibility of autonomous recording units.

Using acoustic indices to detect interspecific bird interactions and behaviour
Ibis, EarlyView.Communication networks and acoustic interactions play a crucial role in shaping animal communities by mediating information exchange between individuals. These interactions contribute to the biophonic component of the soundscape—the acoustic environment of a place—which is increasingly analysed to understand ecosystem structure and functioning. However,

The impact of conservation translocations on vector-borne parasites : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Ecology at Massey University, Palmerston North, New Zealand [PDF]
, 2015 Wildlife conservation in New Zealand relies on translocations of endangered species to safe sites. While knowledge of the biology and behaviour of translocated hosts has steadily increased, the role of parasites in wildlife translocations has been ...

Sex‐biased dispersal in the Arabian babbler (Argya squamiceps)
Ibis, EarlyView.Sex‐biased dispersal plays a central role in shaping social structure and reproductive strategies in many bird species. In the Arabian Babbler Argya squamiceps, a cooperatively breeding species with pronounced male philopatry, dispersal occurs individually or in kin‐based same‐sex coalitions.

Ibis, EarlyView.The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,

BMC Ecology, 2019 Background In recent decades, a decrease of passerine densities was documented in Mediterranean shrublands. At the same time, a widespread encroachment of Aleppo pines (Pinus halepensis) to Mediterranean shrubland occurred.

Ejaculate allocation by male sand martins, Riparia riparia [PDF]
, 2001 Males of many species allocate sperm to ejaculates strategically in response to variation in the risk and intensity of sperm competition. The notable exception is passerine birds, in which evidence for strategic allocation is absent.
