Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

Ibis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

Insect Conservation and Diversity, EarlyView.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.

Incorporating light pollution into projections of the future distribution of Aspisoma sticticum Gemminger, 1870 under climate change in South America

Insect Conservation and Diversity, EarlyView.
Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.

Caste‐Associated Social Context Modulates Behavioural Interactions With Insecticide‐Exposed Individuals in Nasutitermes corniger (Termitidae: Nasutitermitinae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strategy.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods

Journal of Fish Biology, EarlyView.
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

Journal of Fish Biology, EarlyView.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...
