ABSTRACT Highways are structures that cause major impacts and threats to biodiversity. We analysed the effects of a highway on the abundance of the Rufous-capped Antthrush (Formicarius colma) in the stretch that intersects the Sooretama Biological Reserve, located in southeastern Brazil. Data were collected using the point-count census method, with points located on the forest edge near the highway

ABSTRACT The Plains-wanderer (Pedionomidae: Pedionomus torquatus) is a species of Australian shorebird that exclusively inhabits open grasslands. The reported presence of this species in the fossil deposits of Naracoorte Caves suggests that it once inhabited a wooded environment. It was therefore important to assess whether the fossils are indeed conspecific with P. torquatus before inferences on the

ABSTRACT Cooperatively breeding species vary widely in degree of social complexity, and disentangling relationships among group members can reveal the costs and benefits of cooperation. Here, we describe the social system of the cooperatively breeding Variegated Fairywren (Malurus lamberti) and explore how social complexity and group dynamics may affect cooperation and conflict.

ABSTRACT The decline of woodland birds around the world is well known.

Similarly, insect declines, which likely have been occurring for some time in Australia, have been recorded around the world in recent years, especially in areas of intensive

ABSTRACT Island endemic birds represent approximately 90% of contemporary avian extinctions globally. Introduced predators and land-use change are key drivers of population decline in this group. Where multiple threats may compound the impacts on species, the implementation of complementary approaches to threat assessment can be especially valuable.

Mitigation of seabird bycatch in New Zealand squid trawl fisheries provides hope for ongoing solutions Emu Austral Ornithol. (IF 1.3) Pub Date : 2023-06-05 Keith Reid, G. Barry Baker, Richard Wells
ABSTRACT Although there is an increasing awareness of the high rates of seabird bycatch in trawl fisheries globally, there is relatively limited implementation of effective mitigation measures. Seabirds that are attracted to the stern of the trawl vessel to feed on fish-waste can be drowned or injured when they collide with warps/cables or when they become entangled in nets.

ABSTRACT Geographic overlap of Olive-backed Oriole O. sagittatus and the Green Oriole O. flavocinctus is extensive in northern Australia, but they generally are separated by habitat. They overlap in New Guinea, however, where their habitat distinction is much reduced. Genetic methods in an earlier study detected unexpected hybridisation between the two species in New Guinea.
