1. Behavioral and physiological responses of forest musk deer (Moschus berezovskii) to experimental fawn manipulation

Author:

Subject:
Moschus berezovskii; adverse effects; animal behavior; breeding; captive animals; deer; fawns; humans; juveniles; metabolites; phenotype; stress response; urination; weaning; wild animals
Abstract:
... High stress response is an important factor impeding the breeding of wild animals in captivity. Experimental fawn manipulation is considered a suitable approach to reduce the negative effects of behavioral and physiological stress. The forest musk deer (Moschus berezovskii) is classified as “endangered” by the IUCN Red List due to over-exploitation for musk production. Musk is highly valued for it ...

2. Infestation with the parasitic nematode Philometra ovata does not impair behavioral sexual competitiveness or odor attractiveness of the male European minnow (Phoxinus phoxinus)

Subject:
Philometra; Phoxinus phoxinus; animal behavior; courtship; females; hosts; males; minnows; odors; parasites; prediction; sexual selection
Abstract:
... Our understanding on the role of chemical signals in parasite-mediated sexual selection is still limited, and only some existing studies have focused on fish. Furthermore, published studies on the effect of parasite infection on behavioral sexual competition of the male hosts have yielded contradictory results. Here, we examined whether the infection of the body cavity-dwelling parasitic nematode ...

Subject:
Panthera onca; Pteronura brasiliensis; antipredatory behavior; breeding; carnivores; foraging; monogamy; predation; risk
Abstract:
... Group-living in carnivores is mostly associated with cooperative hunting and anti-predator defense. Giant otters (Pteronura brasiliensis) live in monogamous and cooperative breeding groups, where mechanisms other than cooperative foraging may be driving group maintenance in the species. We herein describe three interactions between giant otters and jaguars (Panthera onca) observed in the wild, two ...

4. Signature whistles in wild bottlenose dolphins: long-term stability and emission rates

Author:

ISSN:

Subject:
acoustics; animal behavior; dolphins; estuaries; group size; Portugal
Abstract:
... Whistles are key elements in the acoustic repertoire of bottlenose dolphins. In this species, the frequency contours of whistles are used as individual signatures. Assessing the long-lasting stability of such stereotyped signals, and the abundant production of non-stereotyped whistles in the wild, is relevant to a more complete understanding of their biological function. Additionally, studying the ...

5. Spatial and temporal adjustments allowing the coexistence among carnivores in Liguria (N-W Italy)

Abstract:
... We investigated the seasonal spatial and temporal co-occurrence of three carnivore species in Liguria region (NW Italy)—the red fox (Vulpes vulpes), the European badger (Meles meles) and the wolf (Canis lupus)—using the information provided by camera-trapping monitoring. Data were collected from January 2013 to January 2015 by positioning camera traps in 200 sample stations. During 3479 trap days, ...

Abstract:
... True Shrikes (Laniidae) are sit-and-wait predators that hunt prey from elevated perches and frequently impale them on sharp objects in conspicuous places. During the 2014 breeding season, we followed a pair of Loggerhead Shrike (Lanius ludovicianus) through their reproductive cycle and documented over 100 h of their behavior on video. On three occasions, the shrikes were observed hunting grasshopp ...
