Space invaders: Searching for invasive Smallmouth Bass (Micropterus dolomieu) in a renowned Atlantic Salmon (Salmo salar) river

open access: yesEcology and Evolution, 2020
Humans have the ability to permanently alter aquatic ecosystems and the introduction of species is often the most serious alteration. Non‐native Smallmouth Bass (Micropterus dolomieu) were identified in Miramichi Lake c.

Exploring consumer preferences for wild meat and other animal proteins in Gamba, Gabon: Implications for conservation and management of natural resources alongside extractive industry

open access: yesPeople and Nature, EarlyView.
Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Collaborative approach in the study of the reproductive biology of the dusky grouper Epinephelus marginatus (Lowe, 1834) (Perciformes: Serranidae) = Abordagem colaborativa no estudo da biologia reprodutiva da garoupa verdadeira Epinephelus marginatus (Lowe, 1834) (Perciformes: Serranidae)

open access: yesActa Scientiarum: Biological Sciences, 2006
Several aspects of the reproductive biology of the dusky grouper Epinephelus marginatus were investigated using a collaborative methodology. 193 specimens of dusky groupers were obtained in collaboration with fish market personnel in the city of São ...

Uncommon southwest swells trigger sea urchin disease outbreaks in Eastern Atlantic archipelagos

open access: yesEcology and Evolution, 2020
Recurrent sea urchin mass mortality has recently affected eastern Atlantic populations of the barren‐forming sea urchin Diadema africanum. This new episode of die‐off affords the opportunity to determine common meteorological and oceanographic conditions

From settler gardens to digital naturalists: human aesthetic preferences and land use changes facilitate the biogeographical expansion of a wild plant–virus interaction

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Anthropogenic facilitation of wild plants based on aesthetic preferences for particular traits can change the biogeography and ecology of natural communities. We use a mixed‐methods socioecological approach to characterize the ways in which humans interact with a common, widely distributed plant and a generalist viral symbiont that induces an ...

Relationship between Holocene climate variations over southern Greenland and eastern Baffin Island and synoptic circulation pattern [PDF]

open access: yesClimate of the Past, 2009
Lake pollen records from southwest Greenland and eastern Baffin Island show strong regionalism in climate trends of the last 7000 cal years. July surface air temperature reconstructions from pollen indicate larger amplitude cooling in southwest Greenland

The functional role of ants in no‐till cropping systems

open access: yesPest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

The South Atlantic–South Indian Ocean Pattern: a Zonally Oriented Teleconnection along the Southern Hemisphere Westerly Jet in Austral Summer

open access: yesAtmosphere, 2019
Extratropical teleconnections significantly affect the climate in subtropical and mid-latitude regions. Understanding the variability of atmospheric teleconnection in the Southern Hemisphere, however, is still limited in contrast with the well-documented
