Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Will Females Remain? Fuchsia Excorticata Gender Ratios and Pollen Deposition in Dunedin, New Zealand
Fuchsia excorticata (J.R.Forst. et G.Forst.) L.f. (Kōtukutuku, Onagraceae) is a gynodioecious and bird pollinated tree, with females reliant on pollinators, while hermaphrodites can self‐pollinate. Females are important for population persistence as only they produce female offspring, and all their seed is the product of cross‐pollination so not ...

New records of interesting xenophytes in the Iberian Peninsula [PDF]
New records of interesting xenophytes in the Iberian Peninsula. Botanical inventories in various parts of Spain mainly between 2005 and 2007 yielded numerous chorological novelties.Cyperus prolifer is probably reported for the first time in Europe ...

Seasonal variation in wild pig (Sus scrofa) diet revealed by DNA metabarcoding
Using DNA metabarcoding of fecal samples, we investigated the diet of wild pigs at an extensive bottomland hardwood forest ecosystem within Felsenthal National Wildlife Refuge in Southern Arkansas. We found that wild pig diet was highly diverse and included at least 74 plant families and 106 genera and 23 species of vertebrates.

In low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.

Dominant Species Drive Biomass and Diversity Responses to Nutrient Inputs
In a mesic grassland co‐limited by nitrogen and phosphorus, responses in plant community diversity and particularly of dominant species do not always correspond to responses in aboveground net primary productivity and functional group biomass production.

Temperature and the evolution of flower color: A review
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Understanding the winter diets of endangered ungulates is critical for developing effective conservation strategies in temperate ecosystems, where seasonal fluctuations significantly affect food availability. The long‐tailed goral Naemorhedus caudatus, an herbivorous ungulate listed as a category I ‘Endangered species' (EN) under the Korean Wildlife ...

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.
