Perspectives and behaviors surrounding planting practices in North America inform genetic conservation realities for American ginseng (Panax quinquefolius)

PLANTS, PEOPLE, PLANET, EarlyView.
American ginseng is a shade‐obligate, North American medicinal plant that is widely traded and used internationally. To meet global demand, ginseng is cultivated in forest farms in the Appalachian region of the USA and field‐based artificial shade farms in two regions: Ontario, Canada and Wisconsin, USA. We conducted social research leveraging in‐depth

Beyond abundance: the impact of sampling design on effective population size estimates in capercaillie

Wildlife Biology, EarlyView.
Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.

Inbreeding depression in Solanum carolinense (Solanaceae), a species with a plastic self-incompatibility response

BMC Evolutionary Biology, 2008
Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

Water depth and human disturbance drive occupancy of endangered softshell turtles (Nilssonia spp.) in eastern Nepal

Wildlife Biology, EarlyView.
Freshwater turtles play vital roles in maintaining the health of aquatic ecosystems by supporting ecological balance, nutrient cycling and regulating prey populations. Unfortunately, they are among the most threatened species worldwide. Habitat fragmentation, illegal trade, overharvesting for meat, and use in ethnomedicinal practices have severely ...

Release from natural enemies mitigates inbreeding depression in native and invasive Silene latifolia populations

Ecology and Evolution, 2019
Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success of plant invasions if introduced populations ...

Male Assistance in Parental Care Does Not Buffer Against Detrimental Effects of Maternal Inbreeding on Offspring

Frontiers in Ecology and Evolution, 2018
The severity of inbreeding depression often varies across environments and recent work suggests that social interactions can aggravate or reduce inbreeding depression.

Forty years of captive breeding in Przewalski's horse: pedigree‐based insights into population growth, sex ratio, and inbreeding

Wildlife Biology, EarlyView.
Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Inbreeding depression in crambe1 [PDF]

Pesquisa Agropecuária Tropical, 2016
ABSTRACT Inbreeding depression in plants, caused by selfing or crossing among plants with a high degree of relatedness, is a genetic phenomenon that affects quantitative traits. This study aimed at verifying the occurrence of inbreeding depression in crambe progenies originated from selfing, in comparison with open pollination progenies.

Quantification of human‐caused mortality in an imperiled turtle

Wildlife Biology, EarlyView.
For many threatened and endangered species, the importance of human‐caused mortality relative to other sources has not been quantified, making it difficult to assess the effectiveness of mortality‐reduction strategies. We used radio telemetry data, pooled across studies at protected sites in the US states of Illinois and Wisconsin, to estimate natural ...
