Native habitats in Southern California have been heavily impacted by human use, and open spaces like Crystal Cove State Park are often diminished and fragmented by urban development. Because we are cut off from most other large open spaces in Southern California, we want to know if Crystal Cove State Park is providing adequate space and suitable habitat to support a healthy population of larger mammal species such as coyotes, deer, and bobcats.
Spirostreptus spec. 1 is probably the most frequently kept millipede species in Germany, which is not least due to the easy breeding and uncomplicated keeping. Per brood there can be more than 150 young animals. Spirostreptus spec. 1 is very frugal and is the beginner species par excellence. It can live up to 5 years and reaches sexual maturity at about 2-3 years.
This species is orange and green ringed. It has a slim body. The collum (head shield) is colored orange. Likewise, the antennae and legs of Spirostreptus spec. 1 are orange. In males, the 7th segment is strongly thickened.
A tank for Spirostreptus spec. 1 should have a minimum base area of 40 cm x 40 cm and should also be at least 40 cm high. The substrate should be strewn 10 cm high, better higher. The animals are mainly crepuscular and nocturnal, therefore additional lighting is not necessary. This species is considered to be very frugal, nevertheless a temperature of 21C-26C and a humidity of 60-80% should be aimed at. As with the other species, the temperature should be introduced into the terrarium from above. To keep the humidity in the substrate, it is recommended to cover it with leaves, bark pieces or mosses. Climbing branches should not be missing in the tank. As food they mainly use the organic material contained in the substrate, but also additional food such as vegetables, fruit and millipede food are gladly accepted. As adults they often stay on the surface during the day and can be observed well.
With crocodilian species living up to 75 years in captivity, Evans and his team may have a few more years for breeding success. While zoos and crocodile farms are breeding Cuban crocodiles with the aim that someday they might join their wild relatives, that dream is still out of reach.
William Randolph Hearst was a man of insatiable curiosity and inexhaustible funds to indulge that curiosity. After building the marvel that is Hearst Castle with architect Julia Morgan, Hearst sought to expand the holdings of this property to include varied natural habitats for animals not native to California.
Unfortunately for Hearst Castle, the Hearst Castle Zoo was forced to dismantle due to financial constraints in 1937. All of the animals at Hearst Castle were either donated to public zoos or were sold to private collectors. However, when Hearst Castle was donated to the State of California in 1958, there was still a large variety of animals in and around the property, including some rogue zebras.
Today, Hearst Castle Zebras are most often spotted on the east side of Highway 1 just north of Cambria up to San Simeon and Hearst Castle. The zebras have settled in amongst Hearst Ranch cattle and the two species seem to have struck up a respectful coexistence.
Wildlife Rescue receives over 10,000 wild animals every year. Among these are opossums, raccoons, bobcats, coyotes, skunks, squirrels, and many other mammals along with over 100 species of birds and many reptiles.
Stress is a serious concern when rehabilitating wild animals and we do everything we can to eliminate it. Rehabilitation rooms are kept warm, lights dim, and voices low, and we use calming scents and remedies. Rescued animals, during preparation for release, are given proper housing that mimics what they would have in the wild and veterinary attention when needed.
Animals in rehabilitation can spend anywhere from a few days to several months at WRR before release. It all depends on the species, how old they were when they arrived, and the nature of their injuries. Releases take place on sites that have been inspected and approved by WRR animal care staff. Release sites are often large acreages, and all are chosen to meet species-specific needs for vegetation and terrain and that have year-round water and food sources. All release sites are hunting-free zones.
You might also consider bringing your feeders in at night and offering only what can be consumed within a day on the ground to avoid attracting rats and mice, which will happily nestle into your homestead and raise their many young on bird food. I put mine in a secure tub on the porch.
In the morning I do ground-scatter a breakfast portion of no-mess, high-quality millet (I use a pet bird grade millet mix rather than wild bird mix) and hulled sunflower, enough that will bulk up birds that can ground forage at breakfast but not leave extensive waste. There are some lovely species that just prefer ground-feeding; my beloved mourning doves, blackbirds, and even pine siskins love to forage below the feeders. In the winter I have an abundance of white-throated sparrows and dark-eyed juncos that are particularly appreciative.
A few quick points: when you attract birds, you open up to the potential for more wildlife interaction. If you come across an injured bird, contact a wildlife rehabilitator. It is illegal to rehabilitate native birds without a permit, and there are many risks in causing further harm. The Humane Society has a state-by-state list of links to local sources, and the Tennessee Wildlife Resources Agency breaks down our regional licensed rehabilitators by county. Keep a list of local avian rehabilitators handy.
However, by feeding birds we may be afforded wildlife viewing opportunities we might not expect, and fall in love with those we do. Here are a few of the less common species that came to dine during the storm and have since departed.
Evolutionary biologists Rosemary and Peter Grant spent four decades tracking changes in body traits directly tied to survival in the famous Galpagos finches. They also identified behavioral characteristics that prevent different species from breeding with one another. Their pioneering studies documented natural selection in real time and revealed clues about how 13 distinct finch species arose from a single ancestral population that migrated from the mainland 2 million to 3 million years ago.
Innovations and problem-solving abilities can provide animals with important ecological advantages as they allow individuals to deal with novel social and ecological challenges. Innovation is a solution to a novel problem or a novel solution to an old problem, with the latter being especially difficult. Finding a new solution to an old problem requires individuals to inhibit previously applied solutions to invent new strategies and to behave flexibly. We examined the role of experience on cognitive flexibility to innovate and to find new problem-solving solutions with an artificial feeding task in wild redfronted lemurs (Eulemur rufifrons). Four groups of lemurs were tested with feeding boxes, each offering three different techniques to extract food, with only one technique being available at a time. After the subjects learned a technique, this solution was no longer successful and subjects had to invent a new technique. For the first transition between task 1 and 2, subjects had to rely on their experience of the previous technique to solve task 2. For the second transition, subjects had to inhibit the previously learned technique to learn the new task 3. Tasks 1 and 2 were solved by most subjects, whereas task 3 was solved by only a few subjects. In this task, besides behavioral flexibility, especially persistence, i.e., constant trying, was important for individual success during innovation. Thus, wild strepsirrhine primates are able to innovate flexibly, suggesting a general ecological relevance of behavioral flexibility and persistence during innovation and problem solving across all primates.
The ability to innovate and to find new problem-solving strategies can have important fitness consequences for animals. More innovative individuals or species enhance their ability to exploit new resources, or to use existing resources more efficiently. They may even invade or create new niches or survive the invasion of another species (Kummer and Goodall 1985; Laland et al. 1996; Reader and Laland 2003; Sol et al. 2005; Ramsey et al. 2007; Morand-Ferron and Quinn 2011). For example, innovative anti-predator responses against novel predators (Berger et al. 2001) and adjusted breeding behaviors help animals to survive in changing ecological conditions (Brooke et al. 1998).
Observational studies of innovations in the field are rare, as innovations are scarce and unpredictable (e.g., Gajdon et al. 2006; Turner et al. 2012; Schnoell and Fichtel 2013). Moreover, in order to recognize a behavior as an innovation, long-term behavioral observations are required, complicating field studies even more (van Schaik et al. 2006). However, a few studies have successfully implemented an experimental approach to study innovations in animals in their natural environment (birds: Webster and Lefebvre 2001; Bouchard et al. 2007; Boogert et al. 2010; Morand-Ferron and Quinn 2011; Morand-Ferron et al. 2011; mammals: Biro et al. 2003; Benson-Amram and Holekamp 2012; Thornton and Samson 2012). In contrast to studies on captive animals, which mainly tested separated animals with novel problem-solving tasks (e.g., Manrique et al. 2013), field experiments have the potential to provide more insights into the factors that drive innovation in nature as an entire free-ranging social group can be tested (Ramsey et al. 2007; Reader and Biro 2010).
Recent research revealed that various factors influence problem-solving abilities and behavioral plasticity (Kappeler et al. 2013; Snell-Rood 2013). Innovation rates were found to be a useful tool to quantify species differences in cognition and behavioral flexibility in birds (Lefebvre et al. 1997, 1998; Lefebvre 2000) and primates (Reader and Laland 2002). These studies revealed that innovation rates correlate with relative brain size in both taxa, with more innovative species having enlarged associative brain areas (Lefebvre et al. 1997, 2004; Timmermans et al. 2000; Reader and Laland 2002). Perceptual and learning differences may also influence innovation rates, with individuals that are able to perceive the causal structure of a problem or to generalize across different problems being more likely to innovate (Day et al. 2003).
