Impacts of land use change on diaspore‐dispersing ant assemblages in southwestern Amazonia

Insect Conservation and Diversity, EarlyView.
Land use changes shift ant assemblages, more intensive land uses are dominated by generalist and open habitat specialist species engaging in group foraging. The diaspore removal rates cannot differ, but the quality of dispersal was lower in disturbed habitats.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Marine Sponges as Bioindicators of Nitrogen within Estuaries on the Oregon Coast [PDF]

, 2012
As filter feeders, sponges are highly integrated with their environment. Many sponges also host diverse communities of bacteria, including many that are hypothesized to carry out a variety of nitrogen transformations. The presence of these bacteria makes

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

Journal of Zoology, EarlyView.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

Plant Biology, EarlyView.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

Gold nano-particle modified silica monolithic micro-columns for selected chromatographic and biological applications. [PDF]

, 2011
Monolithic microcolumns and especially silica monoliths are showing several advantages compared to classical particle packed and organic polymeric monolithic columns: ease of production and functionalisation, excellent mechanical and thermal stability ...

Biodiversity and its restoration in limestone quarries: a review

Restoration Ecology, EarlyView.
Abstract Introduction Limestone quarries impact natural areas, and they are spreading in relation to human population growth. Little is known about the impact of limestone quarries and their restoration on biodiversity. Objectives This review aims to provide an overview of how biodiversity is assessed in limestone quarries, how it impacts biodiversity,

Trait‐based recovery of insect functional diversity following pine removal in a shrubland biodiversity hotspot

Restoration Ecology, EarlyView.
Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...
