Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Isolation of Acetic Acid-Producing Bacterial Strains and Utilization as Microbial Inoculants in Sorghum Silages

Agriculture
This study aimed to isolate, characterize, and identify acetic acid-producing lactic acid bacteria from fresh sorghum plants and silage, and to evaluate the effect of the isolates as microbial inoculants on taxonomic diversity and silage fermentation ...

Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

Ecography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Butterfly abundances but not patch occupancy buffered by vegetation heterogeneity during climatic extremes

Ecography, EarlyView.
As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

Factors influencing the conservation characteristics of baled and precision-chop grass silages [PDF]

, 2011
peer-reviewedThe composition of baled silage on Irish farms frequently differs from that of comparable precision-chop silage. This paper concerns a field-scale study designed to investigate: (a) the effects of number of layers (2, 4, 6 or 8) of ...

Long‐distance pollen transport mediated by migratory hoverflies

Ecography, EarlyView.
Long‐distance animal migrations shape ecosystems by redistributing nutrients, connecting populations, and mediating ecological interactions. However, the ecological contributions of many abundant insect migrants remain poorly quantified. Hoverflies are among the most numerous migratory insects and highly efficient pollinators, suggesting that their ...

Effect of equine flysheets on fly avoidance behaviours, body temperature, stress level, and heart rate

Equine Veterinary Journal, EarlyView.
Abstract Background Flysheet use is common without any published scientific evidence to justify their use. Objectives To demonstrate the effectiveness of flysheets at reducing fly avoidance behaviours and measuring changes in body temperature, heart rate, and cortisol levels. Study Design Ten‐week alternating crossover design.

Effects of Additives on the Fermentation Quality and Bacterial Community of Silage Prepared from Giant Juncao Grass Grown in Saline–Alkali Soil

Agronomy
This study investigated the effects of different additives on the fermentation quality and bacterial community of silage prepared from Giant Juncao grass (Cenchrus fungigraminus) grown in saline–alkali soil. Four treatments were compared: a control group

Legacy effects of redlining on the distribution of greenspaces in US cities

Frontiers in Ecology and the Environment, EarlyView.
We investigated how a discriminatory housing policy—redlining—has shaped the spatial patterns and configurations of greenspaces throughout 177 cities in the contiguous US. Housing segregation has been a long‐term development practice that has sequestered communities of color to areas with elevated environmental and public health risks.
