Long‐term demography and spatial genetic structure reveal mechanisms of Sassafras albidum population persistence through clonality

American Journal of Botany, EarlyView.
Abstract Premise Vegetative regeneration is a key mechanism of woody plant persistence in forest ecosystems, and the coupled roles of basal sprouting and clonal growth in shaping long‐term population dynamics have been understudied. Basal sprouting replaces stems at fixed ramet locations, whereas clonal growth via root suckering produces spatially ...

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

American Journal of Botany, EarlyView.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

Pearl's causality for integrating ecological datasets: A case study on Myricaria germanica in northern Italy

Applications in Plant Sciences, EarlyView.
Abstract Premise Applied ecology can significantly influence policy decisions on environmental issues. Therefore, research in this field should be as transparent and reproducible as possible. Existing expertise from a broad range of disciplines should also be integrated into ecological research to allow researchers to maximize understanding of complex ...

Ontogenetic influences on foraging and mass accumulation by big brown bats (Eptesicus fuscus) [PDF]

Journal of Animal Ecology, 1998
SummaryJuvenile flying animals, including bats, often cease increasing, or even decrease in body mass after the onset of flight. The low body mass of juvenile bats may be a result of stresses associated with the initiation of flight, or may be an adaptation to reduce flight costs.To test these hypotheses, the body masses of adults and unknown aged ...

Variation in parrot jaw musculature

The Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Carbohydrate complex of green mass of leguminous forage crops

Feeds and Feed Production
Purpose. To analyze the significance of each of the indicators that are determined and used to characterize the carbohydrate-lignin complex of the green mass of legumes and cereals. Methods. In air-dried samples of the green mass of forage crops (alfalfa, sainfoin, goat's rue, horned yam, creeping clover, Pannonian peas), the content of crude fiber was

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

The Performance of an Alfalfa–Sainfoin Mixture in the Semiarid Southern High Plains of the USA

Crops
While alfalfa (Medicago sativa) is widely used as forage because of its many positive attributes, there are concerns regarding bloat in grazing ruminants, but tannin-containing legumes, such as sainfoin (Onobrychis viciifolia), are non-bloating. Based on
