Background The trade in manta ray gill plates has considerably increased over the last two decades. The resulting increases in ray mortality, in addition to mortality caused by by-catch, has caused many ray populations to decrease in size. The aim of this study...

Background The diversity and composition of the microbial community of tree leaves (the phyllosphere) varies among trees and host species and along spatial, temporal, and environmental gradients. Phyllosphere community variation within the canopy of an individual...

Urban habitats are characterized by a number of unique environmental variables, including modified vegetative structure, fragmentation, small patch size, invasive species, and higher levels of anthropogenic noise. Many songbird species are found less frequently...

Biodiversity-ecosystem function (BEF) experiments routinely employ common garden designs, drawing samples from a local biota. The communities from which taxa are sampled may not, however, be at equilibrium. To test for temporal changes in BEF relationships, I assembled...

Longitudinal studies focusing on lifetime reproductive success (LRS) have been used to measure individual breeding performance and identify commonalities among successful breeders. By extending the focus to subsequent generations we identify a proportion of high-quality...

Background Vestimentiferan tubeworms are some of the most recognizable fauna found at deep-sea cold seeps, isolated environments where hydrocarbon rich fluids fuel biological communities. Several studies have investigated tubeworm population structure; however,...

Small mammals play important roles in many ecosystems, and understanding their response to disturbances such as cattle grazing is fundamental for developing sustainable land use strategies. However, how small mammals respond to cattle grazing remains controversial....

Throughout much of North America’s boreal forest, the cyclical fluctuations of snowshoe hare populations (Lepus americanus) may cause other herbivores to become entrained in similar cycles. Alternating apparent competition via prey switching followed by positive...

Strange patterns of white discoloration on leaves as well as unusual outgrowth that resembles arrested generation of new branches on stem were observed on a plant in Singapore. The white discoloration patterns were random in size and shape but radiated from the...

Aim: Barriers continue to be built globally despite their well-known negative effects on freshwater ecosystems. Fish habitats are disturbed by barriers and the connectivity in the stream network reduced. We implemented and assessed the use of barrier data, including...

Coastal birds are critical ecosystem constituents on sandy shores, yet are threatened by depressed reproductive success resulting from direct and indirect anthropogenic and natural pressures. Few studies examine clutch fate across the wide range of environments...

Parrotfish are fundamental species in controlling algae phase-shifts and ensuring the resilience of coral reefs. Nevertheless, little is known on their ecological role in the South-western Atlantic Ocean. The present study analysed the ontogenetic foraging activity...

Background Global demand for food has led to increased land-use change, particularly in dry land ecosystems, which has caused several environmental problems due to the soil degradation. In the Cuatro Cienegas Basin (CCB), alfalfa production irrigated by flooding...

Background. Organism biomass is one of the most important variables in ecological studies, making estimations of organism weight one of the most common laboratory tasks. Biomass of small macroinvertebrates is usually estimated as dry (DW) or ash-free dry weight...
