The nest building and beckoning behaviour, the female premating moult, the mating process, and parental care demonstrated by a pair of captive Macrobrachium australiense are described and compared with the reproductive activity previously recorded for several other palaemonid shrimps. This is believed to be the first record of nest building activity in the Natantia. Although M. australiense will breed in captivity without any apparent difficulty, the relatively low fecundity and small size of adults of this and most other Australian species of Macrobrachium seem to limit their economic potential for aquaculture.

AbstractPrevious data on crested porcupine reproduction biology were mostly collected in captivity or semi-captivity due to its elusive, burrowing and mainly nocturnal habits. Between 2017 and 2019 the reproductive behaviour (i.e., intrapair mounting and copulation, birth and parental care) of free-ranging crested porcupine was documented and described. Nightly rhythms of single and multiple mounting occurred throughout the year while only two copulation events were recorded. Three months after both copulation events, the birth of porcupettes (porcupine < 5 kg) was recorded. A stochastic phase characterized by an articulate courtship with distinct behavioural patterns always preceded each mounting event. After the stochastic phase, the presenting of the female evoked by Nose-Quill contact behaviour, occurred in 83.8% (n = 182) of mounting events, while in 16.1% (n = 35) a spontaneous presenting of the female occurred. The average duration of copulation lasted 24 s (SD = 7 s) with 17 thrusting (SD = 5.5 thrusting). Births of porcupettes occurred throughout the year from 1 to 3 times per pair per year and the litter size observed ranged from 1 to 2 porcupettes. The first emerging of porcupettes from burrow occurred at 10–15 days after birth. Parents and sub-adults of the family actively perform parental care and the permanence of sub-adults within the family (i.e., from birth to dispersal) resulted to be at least 1 year. This investigation provides new useful insights on porcupine reproductive behaviour in the wild. Such new knowledge may be useful to the management of porcupines in wild, semiwild and captive condition as well as to delineate the key habitat desiderata of this rodent.

Tachyglossus Aculeatus

Captive breeding of the short-beaked echidna (Tachyglossus aculeatus) has proven a difficult challenge; as recently as 2009, there were fewer than 10 echidnas born in captivity. We present observations of captive reproductive behaviour following video surveillance and measurements of body temperature collected from six captive female echidnas over a six-year period. In the first series of observations (2009–10) we examined the efficacy of artificial burrow boxes as possible aids for reproductive success. Females with access to burrow boxes had significantly higher levels of reproductive activity (P = 0.001), there was coincidental improvement in the production of eggs or pouch young (two eggs, one unhatched and one offspring). During 2009–10, a range of reproductive behaviours (courtship, copulation and postcopulation) were documented and analysed, as were new observations of oestrous cycle activity. Female body temperature was characteristically stable during egg incubation during this study and has the potential to be used as a tool for the assessment of reproductive status. Following initial observations, burrow boxes and infrared lamps were implemented as standard husbandry in our echidna breeding facility and the effects on reproductive success were monitored, albeit less intensively, for a further four years (2011–14). Although no direct causal effect could be ascribed, the use of burrow boxes and heat lamps coincided with a total of 13 young being born to four females in the last four years (2011–14). These female echidnas were found to be receptive at intervals throughout the breeding season, both before and after presumed incubation phases, suggesting that captive animals exhibit polyoestry. In 2012 and 2014, the same female showed evidence of producing two young from one breeding event.

AbstractThe lichen genus Lecanactis Körb. in Tasmania comprises six species: L. abietina (Ach.) Körb., which is widespread and pan-temperate; L. latispora Egea & Torrente and L. neozelandica Egea & Torrente, both shared with New Zealand and with the former recorded here from the Auckland Islands for the first time; L. mollis (Stirt.) Frisch & Ertz, shared with Victoria and New Zealand; L. aff. dilleniana (Ach.) Körb., a European species recorded provisionally for Tasmania on the basis of several sterile collections; L. scopulicola Kantvilas, which is described here as new to science and apparently a Tasmanian endemic. This new taxon occurs in rocky underhangs and is characterized by a thick, leprose thallus containing schizopeltic acid, and 3-septate ascospores, 19–30 × 4.5–6 μm. Short descriptions and a discussion of distribution and ecology are given for all species. A key for all 11 Australian species of the genus is provided, including L. subfarinosa (C. Knight) Hellb. and L. tibelliana Egea & Torrente, which are recorded for Australia for the first time, and L. platygraphoides (Müll.Arg.) Zahlbr., a first record for New South Wales. Lecanactis spermatospora Egea & Torrente and L. sulphurea Egea & Torrente are also included.

THE musky rat-kangaroo (Hypsiprymnodon moschatus) is endemic to the tropical rainforests of north-east Queensland (Johnson and Strahan 1982). It is the smallest (510 ? 530 g) and most unusual member of the marsupial superfamily Macropodoidea (Dennis and Johnson 1995). Unlike other macropodoids, H. moschatus is frugivorous, diurnal, has an opposable first digit on the pes, a running quadrupedal gait and possesses a relatively unspecialised digestive tract (Johnson and Strahan 1982; Dennis 2002). It also differs from all other macropodoids in typically giving birth to multiple young, usually twins ? although single young and triplets are regularly reported both in the wild and in captivity (Troughton 1967; Johnson and Strahan 1982; Johnson et al. 1983; Dennis and Marsh 1997; Lloyd 2001). However, the birth of more than three young has not previously been observed in H. moschatus or any other macropodoid, even though all species possess four teats.

Conditions leading to successful reproduction of Didelphis marsupialis in captivity are described. A trial involving four mating pairs which had been maintained at least four months in the laboratory resulted in three litters and one false pregnancy. This is, to our knowledge, the first record of successful breeding of this species in captivity.

Abstract: Blood samples collection is a common method in biological research using domestic animals. However, most blood sampling techniques are complicated and highly invasive and may therefore not be appropriate for wildlife animals in research concerning stress. Thus, a non-invasive method to measure steroid hormones is critically needed. The first goal of this study was to determine how glucocorticoids concentrations are impacted by translocation and reproductive activity in crab-eating-fox (Cerdocyoun thous) in captivity. The physiological relevance of fecal glucocorticoid metabolites was further validated by demonstrating: (1) The translocation of a male to a females enclosure resulted in a 3.5-fold increase compared to baseline concentrations, (2) changes in adrenocortical activity, as reflected in concentrations of fecal cortisol metabolites during reproduction, gestation and lactation in females foxes, indicating that social interactions resulted in large increases of fecal glucocorticoids metabolites during the reproductive season. From these findings we conclude that fecal samples can be used for the non-invasive assessment of adrenocortical status in crab-eating-fox.

ABSTRACT The blue discus (Symphysodon aequifasciatus) is often sold for ornamental purposes. It is a neotropical cichlid from South America, which is native to the rivers of the Amazon basin of Brazil, Peru and Colombia. The purpose of this study was to characterize the reproductive behavior of S. aequifasciatus and identify features that can later be used by breeders to facilitate the handling and reproduction of this species in captivity. The experiment was divided into two stages: the first dealt with partner selection and couple formation to observe the behaviors of territoriality, pursuing, fleeing, biting, stay, protecting and cleaning of the substrate. The second stage documented mating behavior, nesting and parental care, to observe vibration, spawning, permanence with the offspring, aeration of eggs, cleaning of spawning, color change and shift-taking in parental care. The results of the study allowed identifying disputes for and establishment of territory, as well as the selection and cleaning of the substrate for spawning performed by both sexes. The parental care was observed from spawning in the substrate until the care for the larvae. It was found that the reproductive success of this species is closely linked to biparental care observed during the entire reproductive process and early stages of the hatchings.

To satisfy stringent welfare criteria a farrowing pen must meet the sows’ needs for freedom of movement and allow her to exhibit most normal behaviours.Pens must be designed which provide adequate space for the loose housed farrowing sow but which have additional features to promote high standards of pig care. The sow should not be left to farrow indiscriminately within the pen but must be provided with an enriched environment to satisfy both her needs and those of the piglets. Within the pen the sow requires a suitable nest site and material to manipulate immediately pre-farrowing. These features can only be provided when it becomes known what the sows’ find desirable. In previous work it was shown that sows’ preferred to build their nests and farrow within a cubicle rather than in a corner or against a straight but open wall and that sows exhibit intensive nest building activity in the 14 hours before farrowing. In this trial the objective was to determine the farrowing sows’ response to an arrangement of parallel walls spaced 0.55, 0.95 and 1.35 m apart. The rationale behind the measurements was that they approximated to the body width, height and length of a generalised sow. Information about the sows’ response to such a wall arrangement would be useful if pens with walk-through nests were being designed.
