Evaluation of Biochar as a Litter Amendment for Commercial Broiler Production

Journal of Applied Poultry Research, 2019
SUMMARY: Litter amendments are commonly used in commercial broiler production to improve litter quality and overall house conditions. While litter amendments used to limit the formation of gaseous ammonia have been studied extensively, there has been ...

Fungal ecological strategies reflected in gene transcription - a case study of two litter decomposers. [PDF]

, 2019
Microbial communities interplay with their environment through their functional traits that can be a response or an effect on the environment. Here, we explore how a functional trait-the decomposition of organic matter, can be addressed based on genetic ...

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Effects of burial on leaf litter quality, microbial conditioning and palatability to three shredder taxa [PDF]

, 2012
1. Heterotrophic microorganisms are crucial for mineralising leaf litter and rendering it more palatable to leaf-shredding invertebrates. A substantial part of leaf litter entering running waters may be buried in the streambed and thus be exposed to the ...

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Three invasive insects alter Cycas micronesica leaf chemistry and predict changes in biogeochemical cycling

Communicative & Integrative Biology, 2016
Leaf litter chemical traits were measured for Cycas micronesica plants in Guam following leaf herbivory by the scale Aulacaspis yasumatsui, the butterfly Chilades pandava caterpillar, or the leaf miner Erechthias sp. to determine the influence of the non-

Ecological integrity of boreal streams [PDF]

, 2007
Running waters provide a number of services for humans, such as drinking water and food resources and many freshwater animals are confined and specialised to this environment.

Assessment of broiler chicken welfare in Southern Brazil [PDF]

, 2016
Scientific literature on broiler chicken welfare in Brazilian industrial systems is scarce. This study aimed at assessing broiler chicken welfare on industrial farms in the State of Rio Grande do Sul, Southern Brazil, using the Welfare Quality (R ...

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Responses of microbially driven leaf litter decomposition to stream nutrients depend on litter quality

Hydrobiologia, 2017
Este artículo contiene 14 páginas, 4 figuras, 1 tabla. The present study aims to understand how microbial decomposition of leaf litter from two riparian tree species differing in their quality varies among streams covering a gradient of nutrient concentrations. We incubated leaf litter from alder (Alnus glutinosa) and sycamore (
