The California Department of Fish and Wildlife (CDFW) works with agencies, organizations, and other interested persons to study, protect, and preserve CESA-listed species and their habitats. CDFW also conducts scientific reviews of species petitioned for listing under CESA, administers regulatory permitting programs to authorize take of listed species, maintains an extensive database of listed species occurrences, and conducts periodic reviews of listed species to determine if the conditions that led to original listing are still present.

The law requires federal agencies, in consultation with the U.S. Fish and Wildlife Service and/or the NOAA Fisheries Service, to ensure that actions they authorize, fund, or carry out are not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of designated critical habitat of such species. The law also prohibits any action that causes a "taking" of any listed species of endangered fish or wildlife. Likewise, import, export, interstate, and foreign commerce of listed species are all generally prohibited.
Any type of wild plant or animal may be included in the list of species protected by CITES [see Resolution Conf. 9.24 (Rev. CoP17) and the range of wildlife species included in the Appendices extends from leeches to lions and from pine trees to pitcher plants. While the more charismatic creatures, such as bears and whales, may be the better known examples of CITES species, the most numerous groups include many less popularized plants and animals, such as aloes, corals, mussels and frogs.
The aye-aye eats grubs (insect larvae), which it finds by tapping on trees with its fingers. By listening carefully to the noise produced by the tapping, it can tell if a grub is hidden under the bark.
Macaws are members of the family Psittacidae, one of the three parrot families (not all of the members of this family are macaws). Macaws are large, colorful birds with large bills and long tails. Most species can be told apart from other parrots by their featherless faces.
After diagnosis of tarantula hair ocular injury, the first decision to be made in terms of treatment is whether removal of the hairs should be attempted. Some reports suggest better outcomes if the hairs can be removed [6, 15]. Our patient responded very well to simple removal of the offending hairs and a very short course of topical antibiotic/steroid combination therapy. However, removal of the hairs is not appropriate in all cases [3, 9]. Factors that suggest leaving the hairs include: a large number of hairs, deep corneal penetration, lack of patient tolerance, and risk of perforation . It has been suggested that the removal of deeper hairs is not necessary because the hairs may be absorbed without further complications [1, 7].
A recent global review of birds caught in spider webs reported only three Asian cases. Given this surprisingly low number, I made a concerted effort to obtain additional Asian cases from the literature, the internet, and field workers. I present a total of 56 Asian cases which pertain to 33 bird species. As in the global dataset, mostly small bird species were caught in spider webs, with a mean body mass of 17.5 g and a mean wing chord length of 73.1 mm. Consequently, birds with a body mass >30 g were very rarely caught. This Asian review corroborates the global review that smaller birds are more likely to be caught and that Nephila spiders are most likely to be the predators. Continuous monitoring of spider webs is recommended to ascertain the frequency of these events.
Birds should therefore always attempt to avoid collision with spider webs, while the interests of spiders may differ depending on the species. Some spider species opportunistically consume trapped birds (especially large Nephila spiders, see below) and may therefore keep their webs inconspicuous to birds. However, other spider species apparently try to avoid collisions and the consequent damage to their webs by making them more visible to birds (Bruce et al. 2005; Walter and Elgar 2011).
Certainly, a bird being caught in a spider web remains a rather rare event. I never encountered such a case in several years of birdwatching in tropical and subtropical regions, and 58 out of 68 people (85 %) who replied to my request for information also never encountered such a case. The remaining people had only encountered one case in their entire life except for Amar-Singh H., S. Pande, P. Round, G. Welch, and C.-t. Yao who each had encountered two (this does not include the multiple cases reported in the publications of Boedijn 1933; Manchi and Sankaran 2009; Kasambe et al. 2010). For any small bird, it is nevertheless a considerable risk because it carries the highest fitness cost, i.e. death. Combined with the facts that some spider species attempt to make their webs more visible to birds (Bruce et al. 2005; Walter and Elgar 2011), presumably to avoid collisions and the consequent damage to their webs, and that small bats are also at risk of spider predation (Nyffeler and Knörnschild 2013), the risks of collision, entanglement or death are probably high enough to facilitate the evolution of some avoidance behaviour in small birds. Even for larger bird species, there may be fitness costs; a 142 g Hooded Butcherbird (Cracticus cassicus) had to spend several minutes to preen itself after a collision with a spider web (Brooks 2012). To even begin to evaluate the magnitude of this risk, continuous video monitoring of spider webs would be required to establish collision frequencies, or captive birds could be used in experimental settings with spider webs.

The Southern Ocean around Antarctica is no longer free from invasive marine species. The North Atlantic spider crab Hyas araneus (Linnaeus, 1758) (Crustacea: Decapoda: Majidae) has been recorded for the first time from the Antarctic Peninsula. Isolated for at least 25 million years, the endemic Antarctic Southern Ocean marine fauna is now being exposed to human-mediated influx of exotic species. Invasive species and polar warming combined can foster the probability of arrival and colonization by non-indigenous species, with unpredictable consequences for the Antarctic marine biota.
