Effects of Redhead Nest Parasitism on Mallards [PDF]
, 1981 Female Redheads (Aythya americana) are known to deposit eggs in nests of Mallards (Anas platyrhynchos). Joyner (J. Wildl. Manage. 40:33-38, 1976) attributed a high rate of Redhead parasitism on Mallard nests at Farmington Bay, Davis Co., Utah, to ...

Parental-care parasitism: how do unrelated offspring attain acceptance by foster parents?
, 2011 In this review, we describe a new term, "parental-care parasitism", that we define as the interaction in which an individual (the parasite) obtains reproductive benefits while reducing or completely eliminating its own costs of parenting by exploiting ...

PLANTS, PEOPLE, PLANET, EarlyView.Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...

Pest Management Science, EarlyView.Combining intensive drone‐brood removal with brood interruption provided the most effective and consistent seasonal Varroa control. Abstract BACKGROUND Varroa destructor remains the most significant biotic threat to honey bee colonies, and increasing resistance to synthetic acaricides necessitates alternative control strategies.

Breeding Behaviors and Kinship in the Endangered Hawaiian Stilt (Ae‘o; Himantopus mexicanus knudseni) [PDF]
Ecol EvolA comparison of behavioral observations with genetic analyses of the Hawaiian Stilt on Molokaʻi revealed some evidence of conspecific parasitism, potential extra‐pair paternity, and inbreeding, although most observed family groups clustered together genetically, suggesting these alternative tactics may be relatively rare.

Modeling parasitism rate and parasitism risk: An illustration using a colonially nesting songbird, the red-winged blackbird \u3ci\u3eAgelaius phoeniceus\u3c/i\u3e [PDF]
, 2009 Ornithologists interested in the drivers of nest success and brood parasitism benefit from the development of new analytical approaches. One example is the development of so-called “log exposure” models for analyzing nest success.

Pest Management Science, EarlyView.Differences in the suitability of invasive alien plants as hosts drove variations in cascading bottom‐up effects in aphid host and parasitoid performance, potentially influencing top‐down regulation. Abstract BACKGROUND Invasive alien plants (IAP) can threaten biodiversity by disrupting trophic interactions and, consequently, affect agroecosystems by ...

Forest and fire drive moose (deníe) detections near their northern range limit
Wildlife Biology, EarlyView.One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...

Unraveling the origins of social parasitism in Megalomyrmex ants [PDF]
, 2008 textSocial parasitism, the exploitation of a society by other social organisms, has evolved independently numerous times within social animals. In this thesis, I integrate behavioral, evolutionary and chemical analyses to elucidate the evolution of ...
