Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Tracking habitat use of migratory birds in a human‐dominated stopover site using deep learning and acoustic indices

open access: yesEcosphere
Bird migration is a fascinating behavioral phenomenon on earth, with annual movements along migratory routes forming complex migration networks. Stopovers, which serve as fuel stations for migratory birds, are critical to the success of long‐distance ...

Conservation of the critically endangered frog Telmatobufo bullocki in fragmented temperate forests of Chile : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Conservation Biology at Massey University, Albany, New Zealand [PDF]

open access: yes, 2015
Amphibians are currently facing several threats and are suffering severe population declines and extinction worldwide. Telmatobufo bullocki (Anura: Calyptocephalellidae) is one of the rarest and most endangered amphibian species in Chile's temperate ...

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

A Nested Demand Shares Model of Artificial Marine Habitat Choice by Sport Anglers [PDF]

open access: yes
There is growing public interest in the development of artificial habitats to enhance and diversify coastal marine resources for recreational and commercial uses. In this article, a hierarchical discrete choice model of recreational demand for artificial

Flower color variation in Digitalis purpurea: Pollination and soil influences across native and introduced populations

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

Construction of pathogenic Sec16a mutation mouse model using CRISPR/Cas9

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Yaqiang Hu et al. engineered a pathogenic Sec16a mutant mouse model using CRISPR/Cas9 technology. They observed that the Sec16a mutant mice displayed diminished learning and memory capabilities, along with a limb‐clasping phenotype upon tail suspension.

Comparative patterns of winter habitat use by muskoxen and caribou in northern Alaska [PDF]

open access: yes, 1992
Thesis (M.S.) University of Alaska Fairbanks, 1992Snow depth and hardness strongly influenced selection of feeding zones, (i.e., those areas used for foraging), in late winter by both muskoxen (Ovibos moschatus) and caribou (Rangifer tarandus grand) in ...
