AbstractAgonistic encounters and facultative parental care in Hyla faber were observed in two localities in southeastern Brazil. Maximum male density was 0.9 and 3.3 males/m2 in Campinas and Ribeirão Branco, respectively. Aggression was escalated and the highly variable aggressive calls were specific to each phase of the encounter. The last, more aggressive phases rarely occurred in Campinas; in Ribeirao Branco they occurred frequently. Male parental care (egg attendance) was common in Ribeirao Branco while it was never observed in Campinas. Egg attendance lasted one to two nights and was observed only during high male density. The main benefit of egg attendance seemed to be avoiding nest intrusion by other males (sunken eggs and/or embryos invariably die). Males may build additional nests during egg attendance, but attending males did not attract females (they did not call).

Although we celebrate the centennial of Brachycephalus garbeanus’ discovery, little progress has been done on understanding this species’ biology apart from a few morphological and ecological studies, which includes its redescription based on three specimens from the type-series, microhabitat use, sexual dimorphism in body size, and feeding habits. This species is endemic to the Serra dos Órgãos Mountain range, in the state of Rio de Janeiro, southeastern Brazil. Here we redescribe B. garbeanus based on a wide sampling, including its advertisement and aggressive calls, and also the chigger mites infestation pattern. The advertisement call is longer than 25.8 s with pulsed notes series emitted at an average rate of 2.3 notes/s and 14.1 pulses/s; long inter-note interval with 320 ms; notes with distinctly short pulses (1 to 16 ms); low dominant frequency for this genus (3.0-5.4 kHz) and presence of four harmonics. This species is often parasitized by chigger mites of Hannemania, with a prevalence of infection of 67%, mainly affecting the ventral body surface. Females had a higher prevalence of parasites than males and there was no correlation found between the size of specimens and the number of parasites. Our study, provides an important and overdue taxonomical contribution, including a large amount of novel information for B. garbeanus.

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.

Abstract The non-native African tuliptree, Spathodea campanulata (P. Beauv), is widely distributed in altered Neotropical environments, where hummingbirds are important pollinators. We investigated the assemblage of hummingbirds which fed on its nectar and described their behavior, to understand possible influences of the exotic tree on the territorial behavior in an altered environment in southeastern Brazil. Seven species fed on flower resources, mainly Eupetomena macroura (Gmelin, 1788), Amazilia lactea (Lesson, 1832), and Florisuga fusca (Vieillot, 1817). Visiting time was positive correlated with number of flowers accessed, but in most visits, hummingbirds get the nectar by pillage, instead of frontal access. Flower availability varied throughout months; however, we found no evidence of significative correlation between available flowers and number of agonistic encounters. Despite a high number of animal-plant interactions and a strong territorialism of some species observed in African tuliptree foraging site, there may be other plants at local scale influencing the behavioral patterns observed.

Most reptiles exhibit no parental care and aggressive behaviour towards heterospecific predators has rarely been recorded in the natural environment. Several species of the subfamily Egerniinae are amongst the most highly social of all squamate reptiles, exhibiting stable social aggregations and high levels of long-term social and genetic monogamy. We have examined Cunningham’s skinks, Egernia cunninghami, over a three-year period during late January and early February (total 32 days) in the alpine region of New South Wales using video and thermal imaging. Four birthing sessions were witnessed during our field studies of social aggregations of skinks. Our observations monitored skink encounters, in the presence of offspring, with an eastern brown snake, Pseudonaja textilis (two separate encounters, one recorded by video/imaging) and 12 encounters with the Australian magpie, Gymnorhina tibicen. All events were associated with aggressive chasing and/or attack by adult skinks. The first snake encounter involved the active targeting of a recently born juvenile with the mother of the juvenile attacking the snake (running towards the snake, biting and remaining attached for several seconds). The second encounter (the following year) comprised two adult skinks attacking and biting a snake, Pseudonaja textilis. All magpie encounters resulted in chases by adult skinks.

The reproductive behavior of four intertidal hermit crab species [Clibanarius antillensis Stimpson, 1859, C. sclopetarius (Herbst, 1796), C. vittatus (Bosc, 1802), and Pagurus criniticornis (Dana, 1852)] was studied in São Sebastião Channel, southeastern Brazil. The overall behavior followed previous descriptions for Diogenid and Pagurid hermit crabs but some particular differences were recorded. Male to male agonistic encounters over females and guarding behavior were more common to C. sclopetarius, C. vittatus, and Pagurus criniticornis. During guarding, males clearly grasped females' chelipeds, eyestalks, and the margins of their shell apertures. This oblique guarding and, simultaneously, accessing behavior (OGAP) has never been described for hermit crabs and was more common to C. sclopetarius and C. vittatus. Pagurus criniticornis did not present the typical jerking behavior of pagurids. Multiple copulations between a single pair were recorded in all species while in only one occasion a female of C. vittatus was observed copulating with two males. In the post-copulatory behavior males held females for some time and, after that, they were left inactive and sometimes totally to partially buried in the substrate. In mating pairs of all species males were larger than females and two individuals (out of 23) of C. antillensis, one (out of 5) of C. sclopetarius and one (out of 3) of C. vittatus, which courted successfully as males fertilizing females' eggs, were demonstrated to be intersex, with both male and female gonopores.

The objective of this study was to characterize the reproduction of Cichla kelberi in an artificial lake, located in the municipality of Leme, in the state of São Paulo, Brazil. Breeding occurred in spring, and summer. The L50 and the L100 of this species were 192 and 235 mm (L50), for males and females, respectively, and 290 mm (L100) for both sexes. Spawning was parceled. The oocytes matured at a size of 428.4 µm, reaching their maximum at 2,203.2 µm. A mean of fecundity were of 12,129.2 oocytes, with the mean of oocytes in each batch of 4,897.7. This species has external fertilization, is nonmigratory, and with parental care of the young. Various attributes of the peacock bass make their introduction a temptation. However, due to their feeding and reproductive characteristics, they have no natural predators, making it difficult to control their population growth or eradicate them.
