Effects of surface fires on understorey insectivorous birds and terrestrial arthropods in central Brazilian Amazonia.

open access: yes, 2003
Understorey insectivorous birds are highly vulnerable to different forms of habitat disturbance in tropical forests. Here we examine the effects of an unprecedented surface fire on understorey insectivores and forest litter arthropods in a terra firme ...

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

The Presence and Behaviour of Birds at Two Prescribed Fires in Sweden. [PDF]

open access: yesEcol Evol
Shifting fire regimes pose immediate threats to animal conservation. Swedish birds appear to mostly ignore prescribed fire, and some species even continue to sing. Behavioural plasticity towards fire is poorly understood, but may prove to be an essential tool in animal conservation.

Beyond first clutches: Second broods reshape selection on breeding timing in forest and urban great tits

open access: yesJournal of Animal Ecology, EarlyView.
Most studies of selection on breeding timing consider only first clutches. Using a 13‐year dataset of urban and forest great tits, we show that including second broods reshapes estimates of natural selection, revealing that early breeding is favoured through increased probability of multiple brooding and higher annual reproductive output.

Effects of native and non-native shade trees on insect predation pressure on Kenyan coffee farms

open access: yesFrontiers in Conservation Science
IntroductionAgroecosystem practices that aim to increase biodiversity and ecosystem services have the potential to benefit both wildlife and farmers. Shade-coffee systems are well-studied in the Neotropics, but less is known about the relationships among

The density and diversity of birds on farmland in West Africa

open access: yes, 2008
The area of land farmed in Africa is predicted to double by the year 2050 yet very few African studies have investigated the impact of different farming intensities and regimes on bird communities. This study examined avian species richness and diversity

The effect of piospheres on the ecology of insectivorous birds and their arthropod prey

open access: yes, 2023
Desertification is the degradation of arid ecosystems that result in the loss of biodiversity. Piospheres are areas of local degradation around a central point due to overgrazing and increased herbivore presence.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Bird community structure in riparian environments in Cai River, Rio Grande do Sul, Brazil [PDF]

open access: yesBiotemas, 2012
Urbanization produces changes in riparian environments, causing effects in the structure of bird communities, which present different responses to the impacts. We compare species richness, abundance, and composition of birds in riparian environments with
