Temporally‐indexed multi‐species density impact functions: Quantifying timing and impact of invasive predators on seabird breeding success

open access: yesConservation Science and Practice, EarlyView.
Conserving threatened species often requires effective predator suppression strategies, particularly on islands where introduced predators pose significant threats. Density‐impact functions provide a framework to quantify the relationships between predator abundance and impact but are currently limited to a single species with invariant impact.

Summary Account of the Carolina Parakeet in Arkansas [PDF]

open access: yes, 1984
The extinct Carolina Parakeet (Conuropsis carolinensis) once was part of the Arkansas avifauna. The first two reports of the species in what is now Arkansas were made in 1673 and 1718 by early French explorers.

Effectiveness of territorial protection categories in conserving an endemic island bird during population fluctuation

open access: yesConservation Science and Practice, EarlyView.
Static boundaries of protected areas failed to capture the Canary Islands stonechat's shifting distribution patterns. Abstract Protected areas represent cornerstones of biodiversity conservation on oceanic islands, yet their effectiveness for endemic species remains poorly evaluated. We assessed how various territorial protection categories conserve an

The Correlation of Avifauna Diversity and Its Habitat: An Observation Study at Mount Kawi Slope Waterfall, East Java

open access: yesJournal of Tropical Life Science
Avifauna inhabiting mountain forest ecosystems on Java Island face severe threats from anthropogenic disturbances. Despite this, the diversity of avifauna in specific areas, such as the Hutan Lindung Pegunungan Putri Tidur (HLPPT) on the slopes of Mount ...

Contribution of studies for environmental licensing to the knowledge of Santa Catarina avifauna in southern Brazil [PDF]

open access: yesBiotemas, 2006
The knowledge generated by studies for environmental licensing, even with reduced field samplings, can contribute to the recording of species of avifauna or actually extends the distribution in places of low knowledge.

Assessment of land‐based threats to Atlantic pelagic seabirds

open access: yesConservation Science and Practice, EarlyView.
Highly mobile pelagic seabirds face numerous land‐based threats during their breeding seasons, including invasive alien species, climate change, and diseases, which drive population declines. Using field expertise and a literature review, we collated a dataset assessing 18 threats affecting 49 species across 38 Atlantic Large Marine Ecosystems. We used

Zielvorstellungen und Entwicklungsperspektiven für den Ökolandbau aus Naturschutzsicht [PDF]

open access: yes, 2003
Der Ökolandbau wirtschaftet in der Regel deutlich naturnäher als der konventionelle und integrierte Landbau und kommt somit auch den Naturschutzzielen am nächsten.

The caliph and the falcons: a ninth‐century history from Iceland to Iraq

open access: yesEarly Medieval Europe, EarlyView.
In the late ninth and early tenth centuries, an extraordinary number of falcons were given to the ʿAbbāsid caliphs in Baghdad, many of which were white. Gifts from competing dynasties in the northern provinces of the Caliphate, at least some of these birds were almost certainly gyrfalcons from near the Arctic Circle.

Introduced birds in urban remnant vegetation : does remnant size really matter? [PDF]

open access: yes, 2006
Introduced birds are a pervasive and dominant element of urban ecosystems. We examined the richness and relative abundance of introduced bird species in small (1–5 ha) medium (6–15 ha) and large (>15 ha) remnants of native vegetation ...

Species characteristics predict the effectiveness of avian survey methods in an Afromontane sky‐island

open access: yesIbis, 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.
