Integrative Zoology, EarlyView.Some eggs are pyriform as this may attain a larger surface area‐to‐volume ratio making them grow and hatch quicker. ABSTRACT Bird eggs can be spherical, ellipsoid, ovoid, or pear‐shaped (pyriform), the latter being the most complex. There is however no unambiguous evolutionary/adaptive explanation for this final, exotic shape.

Methods in Ecology and Evolution, EarlyView.Abstract Pollinator declines pose a significant threat to ecosystem services, making effective monitoring methods critical for conservation efforts. Current research on pollination interactions remains constrained by traditional methods such as direct observations, which have limited spatial and temporal coverage and are inherently biased toward ...

Pollination ecology in the tropical Andes: moving towards a cross‐scale approach
Biological Reviews, EarlyView.ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Description of a new genus and species of hummingbird from Panama [PDF]
, 1911 Since January, 1911, Mr. E. A. Goldman, of the Biological Survey, U.S.Department of Agriculture, has been detailed to the Smithsonian Biological Survey of the Panama Canal Zone to collect mammals and birds in the Canal Zone and adjacent parts of Panama...

Individual variation in animal communication: from species averages to unique voices
Biological Reviews, EarlyView.ABSTRACT The comparative study of communicative behaviour in non‐human animals, especially primates, has yielded crucial insights into the evolution of human language. This research, mostly focused on the species and population level, has improved our understanding of the various socio‐ecological factors that shape communication systems.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna
Biological Reviews, EarlyView.ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Citizen‐science data provides new insight into annual and seasonal variation in migration patterns
Ecosphere, 2015 Current rates of global environmental and climate change pose potential challenges for migratory species that must cope with or adapt to new conditions and different rates of change across broad spatial scales throughout their annual life cycle.

Biological Reviews, EarlyView.ABSTRACT The ability of individuals to cope with their environment, and therefore the likelihood that they survive and pass on their genes (i.e. fitness), is largely determined by physiological state. Tracking physiological state in wild animals, however, is challenging.

Frontiers in Ecology and EvolutionCurrent studies of animal–plant mutualistic interaction networks and species climate change resilience call for redesigning biodiversity conservation management toward preventing species coextinction cascades and using interspecific hybridization as a ...
